How to Start a Gasoline Grass Trimmer Properly

What oil to use for the grass trimmer?

Oil for 2-stroke trimmer engines must meet slightly different standards than oil for 4-stroke motors. Oil for a lawnmower must have a high degree of combustion, so as not to form soot on the internal parts of the fuel system (particles of soot may fall off and form scratches on the cylinder walls). Also 2-stroke oil should be well soluble in gasoline and be designed to work at high temperature.

With such serious standards in mind, modern garden equipment manufacturers produce special lines of 2-stroke oils designed specifically for trimmers and brushcutters. The oils from manufacturers like Hado and STIHL are ideal for this machine and provide excellent lubrication and have a low flammability level.

The reason why the grass trimmer malfunctions may be:

  • overfilling the tank;
  • Excessive pumping of fuel into engines equipped with a manual supercharger;
  • engine valves, cylinders, injectors, cam tappets and other moving parts are worn;
  • the tanks are out of gasoline and/or oil;
  • Spark plugs are out of order;
  • clogging of the fuel or air filter;
  • engine valves are leaking or burnt out.

How to service a lawn mower

Lawn mower. a popular technique for mowing unwanted vegetation in plots, gardens and parks. But like any other equipment lawnmowers need regular care, maintenance and sometimes minor repairs that you can do yourself. And if you bought a lawn mower, not an electric mower, what kind of gasoline should you fill the fuel tank? In this article we’ll look at the basic principles of chain saw care and tips on what to do with the machine before each start-up, how to prepare the fuel mixture and tell you some grass mowing secrets from experienced gardeners.

Lawnmower maintenance

Here you find information on how to take good care of all the machine’s parts, how to make adjustments, how to disassemble the machine and how to lubricate it (moving parts).

Engine. Keep the air filter clean, foam rubber products should be moistened with oil. The fuel filter needs to be checked at least once a week and replaced in a timely manner in case of malfunction. Muffler and spark plugs should be cleaned regularly (as they become soiled). Before each use, check that all nuts and bolts are properly tightened.

The bevel gear must be cleaned of dust and dirt as needed, since this prevents proper cooling and then lubricated with any type of gear lubricant, e.g. STIHL.

Trimmer head with fishing line. The mowing head must be cleaned after each use of the grass trimmer and replaced in good time if any deformation or cracks are found. Only a special cord (line) should be used for the trimmer, no rope or wire! The line diameter must be as specified for the particular model. The filament must be wound tightly, but without crossing the filaments.

Metal cutting attachments (blades and saw blades). Always sharpen metal objects (special files and templates are available for this purpose) at a special angle. It is desirable to turn the two-sided models from time to time for even wear. Dull or improperly sharpened discs and blades cause overloading of the engine and shorten the service life.

Protective guards must always be worn during mowing. They shelter the operator from flying grass and stones from under the cutting equipment, and reduce the load on the engine. After use, carefully clean the inside and outside of the housing with a jet of water or a soft cloth, taking care not to scratch the surface.

How to adjust the lawnmower (carburetor)

Correct adjustment is essential for the successful operation of the machine in the future.

Beginners sometimes don’t know how important this process is for chain saws and gasoline trimmers, and skip it or simply don’t know how to adjust the carburetor of a lawn mower, believing that the factory settings are quite enough. But this is not the case. All mechanisms should be inspected and the carburetor adjusted at regular intervals.

Important information and tips on tuning the gasoline carburetor in gasoline mowers:

  • There are 3 screws in the carburetor: left (H), bottom (T) and right (L). To get to the screws, you need to know how to disassemble the lawnmower, and more specifically, how to get to the carburetor. This information should be specified in the product data sheet.
  • The lower screw (T) is responsible for idling, the right (L) for the amount of fuel entering the combustion chamber at low RPM, and the left (H) is responsible for fuel entering at high RPM.
  • Turn on carburetor at idle speed. Correctly tuned, it works evenly when the engine is hot and cold, at low and high revs. If something goes wrong, turn lower screw (T).
  • Adjust fuel flow at low rpm by turning the right screw (L) a quarter turn counterclockwise.
  • Setting the carburetor at high RPM is performed as follows: open the throttle and press the maximum throttle. Turn the left screw (H) clockwise until the rpm goes down. Then turn the screw counterclockwise until the engine runs smoothly. Then slowly turn the screw back clockwise until you hear the engine running smoothly and evenly.
  • The spark plug is also an indicator of proper carburetor regulation. If it is defective, the spark plug is soiled, but if it is properly adjusted the spark plug will stay clean.

This is the most universal algorithm on how to adjust the carburetor on a lawn mower. Individual adjustment depends on the configuration of your machine model.

Preparing the fuel mixture for the lawnmower

Many novice users ask what kind of gasoline to pour into the lawnmower? The passport of each lawnmower should specify what fuel can be used with this particular model. However, the grass mower will not work on gasoline alone, you need a fuel mixture prepared in certain proportions. What is in the fuel for chain saws and gasoline trimmers?

Gasoline. any high-octane (AI-92 and 95 and a density of 750 to 770 kg per cube) is suitable.м). The gasoline must be fresh and clean, which means

Oil. you can use oil for two-stroke engines (with 10,000-15,000 rpm) of high quality, such as STIHL, PATRIOT, Husqvarna, Bigmaster will also do.

Fuel mixture proportions. if not stated differently in the product data sheet, you can use this scheme: 1:50 (2 percent oil from 100 percent gasoline) or 20:1000 ml.

One example of how to prepare fuel mixture (proportion 10 ml per 0.5 liter): pour 0.5 liter of petrol into a transparent container, gently add 10 ml of oil (you can use a syringe without needle), mix and pour the rest of the petrol in the end. Stir the mixture thoroughly. If the quality of gasoline is low, you may increase the oil volume to 25 ml.

Our article is an introductory nature, so if you have a lawnmower, how to dilute gasoline (the correct proportions of gasoline and oil) should be specified in the technical passport of the model.

Important! Shake the fuel mixture before each filling, so that the gasoline and oil are mixed evenly. Such fuel should not be stored for more than 2 weeks in favorable conditions (neither frozen nor overheated in the sun). Attention! If the color of fuel has changed (cloudy, darkened), you can not use such a mixture to avoid equipment failure.

A few secrets of how to correctly mow with a chainsaw

Many people know how a lawnmower looks like, how to use it on an overgrown plot of grass. However, there are some tricks that will allow you to mow vegetation faster and more efficiently.

  • Always mow from right to left, so the cuttings will fall over the previously mowed area. This is because the tool rotates counterclockwise.
  • Large and flat areas are best mowed in squares. Always mow from the edge of the field to the middle.
  • Mow high thickets best by moving the weed trimmer from side to side, starting from left to right. The first movement you mow the overall length, and the second. trim.
  • Mowing the slope. Use the straight mowing method. cut the grass along the slope, at the end go back and pass the next line.

Repairing the lawnmower yourself

This information refers to minor repairs to the unit, for major breakdowns or replacing major parts of the grasshopper it is better to contact specialized service centers.

Let’s consider how a lawnmower is arranged: the unit usually consists of the engine, the mowing head and the boom that connects them, as well as additional parts.

How to operate the gasoline trimmer

To prepare the gasoline trimmer for work, it is necessary to begin with an inspection of the condition of all parts, and the new unit should be unpacked and assembled according to the instructions. First you need to check that the gearbox has sufficient lubricant and oil in the crankcase. Next, you should prepare the fuel mixture in the correct proportions specified in the technical documentation for the product and start the engine at idle speed, so that it warms up and is fully ready to work.

Important! Never measure ingredients by eye, it will lead to poor engine performance and early failure of the gasoline trimmer.

The area to be mowed should be prepared for mowing. Clean it of unnecessary objects: large stones, iron, pieces of wood, glass, wire, etc. It is also undesirable to have people within 15 m of you. Depending on the type of vegetation on the site you should choose the right cutting tool: a fishing line is good for soft grass and weeds with thin stems, but a metal knife or a circular saw blade is good for dead grass, bushes and young growth. sites with mixed vegetation is more effective to handle with a knife or disc, this equipment is also suitable for making hay, as the fishing line breaks the grass into small pieces.

Users often add accessories to the basic set, for example, a saw blade. Let’s find out what is the best knife for a petrol trimmer and what varieties of this cutting tool there are.

Metal. more durable and heavy. With such tools the shaft rotates more slowly and needs a more powerful drive, which affects the service life of the motor. There are varieties: 4 or more teeth, solid or peorized, 2-4 blades on one blade. The choice of which type depends on the power of gasoline trimmer, boom type (straight/curved), and the task at hand. As a rule, with curved blades, a metal knife or disc is not used because a foreign object caught under the blade can fly off into a person. Are usually made of tool steel, forged or stamped (cheaper versions).

How to start a string trimmer, starting a weed eater is easy if you know how

Plastic. less strong and durable, but lighter in weight and in operation. Thanks to their flexibility, they reduce the load on the shaft and, consequently, the grass trimmer motor. Use for cutting dense grass, soft and stiff, and weeds, as well as plants with thin stems.

In addition to the classic forms of blades (2 or 4 blades), there is a variety of “Shark”. This equipment is placed in the trimmer head, from which as the rays diverge 3 thin blades, each set at an angle of 120 degrees and adjusted separately from the others. Shark knife cuts grass of different hardness and dead wood.

If you bought a new gasoline trimmer and haven’t used it yet, you should run in the engine to extend the life of the unit.

How to properly run in the gasoline trimmer

The running-in of the engine and the right first start is very important for the gasoline trimmer. They allow the parts to rub against each other and preserve the engine’s service life in the future. In addition, the technical work with the trimmer provides useful skills that will be useful in the operation of this gardening equipment.

The correct algorithm for running-in the engine:

  • Prepare the fuel mixture in the right proportions and pour it into the tank of the gasoline trimmer.
  • Add lubricant to the gearbox if necessary.
  • Run the engine at idle for 5 minutes and let it warm up. Increase the throttle 2 times for half a minute.
  • Turn the engine off for 20 minutes.
  • Do idle and accelerate as described in point 3 and again take a break for 20 minutes.
  • Running in of the gearbox. Mow the grass for 5 minutes and then turn off the engine for 15 minutes. Repeat this operation 4 times.

Run in the power tool until the tank is empty. After this, you can start working hard.

Important! Check the amount of grease in the gearbox and add it every 2-3 hours at the beginning of the operation. It is also important to permanently check the temperature of the engine and gearbox, avoid overheating to prevent damage to the power tool.

How to adjust the ignition of the power tool

The ignition system is involved in starting the engine. If it doesn’t engage, sometimes an ignition adjustment can solve the problem. This system is the same on all types of gasoline trimmers, so the rules for adjusting the ignition will be the same for all models.

The ignition system consists of two parts: the magneto (coil) and the flywheel with the impeller. As the flywheel accelerates, it creates a spark that ignites the spark plug, which ignites the fuel mixture.

A quick guide to adjusting the ignition system

Here’s how to adjust the ignition in a gasoline trimmer. This is a relatively simple procedure. You’ll need screwdrivers and a piece of thin cardboard.

  • The first thing to do is to unscrew the bolts that hold the engine cover and remove it. On some models, you must first remove the air filter cover and then get to the engine housing.
  • Use a screwdriver to remove the two bolts that hold the coil.
  • The flywheel should be turned so that the magnets are on top.
  • Then form an optimum gap between the magneto and the flywheel, this can be made with a small piece of thin cardboard the size of a business card. Place the cardboard between the magnets and the coil.
  • In this position, the magnetic field will attract the magneto to the flywheel. Carefully hold it and at the same time tighten the bolts on it.
  • Get a piece of cardboard.

In this uncomplicated way, you can adjust the ignition system in your gasoline trimmer yourself.

How to properly run in a new lawnmower

And so, if you’re wondering where and how to run the lawnmower correctly, the best solution is to follow exactly the instructions that conscientious manufacturers come with the general instructions for using the grass mower. But before performing this running-in activity correctly and accurately, a special fuel mixture should be prepared, containing high-quality gasoline and oil, the brands of which are specified in the instruction manual used for the grass trimmer. The best effect is achieved if:

  • The octane rating of the gasoline must be at least 95;
  • oil should only be used of the right consistency;
  • Run in and fine-tune the trimmer for the grass in all conditions, taking into account the total time of operation, forced breaks and starting up.

It is also worth remembering that bypassing STIHL trimmers and series of other well-known brands does not protect the device from preventive maintenance, carried out every six months.

Today there are many video reviews of running-in a gasoline brushcutter, explaining the following steps:

  • Using gasoline and branded oil, mix them in a clean bowl in the ratio of 1:25, where per 100 gr. of oil (e.g. 2-stroke) is 2.5 liters of fuel.
  • Check the lubrication of the lower gearbox, adding as needed.
  • Start the engine and let it idle for 5 minutes, and then pump it up every 20-30 seconds. at half-power without harsh throttle. The total length of the process is up to 15 minutes.
  • Let the machine rest for 20 minutes.
  • Turn it on and let it run idle for 5 minutes, after that turn it on every 20-30 seconds. Half-power without sudden movements. Total elapsed time is up to 15 minutes.
  • Allow the machine to rest for 20 minutes.
  • Having charged the mower line of the necessary diameter into the reel, run in the bottom gearbox by mowing soft grass for 5 minutes with a break of 5-10 minutes. Perform 4 repetitions.
  • If everything was done according to the instructions, the gasoline trimmer is ready for operation.
  • If necessary, every 2-3 hours of operation, additional lubrication is introduced into the lower gearbox.
  • Total running-in time. 3-4 hours.

When running in, don’t forget to take into account the time for mowing and resting to avoid overheating the engine and gearbox. In this case it is recommended to arrange the operation mode in the ratio of 15x15min. In very hot weather. 10×20.

How to make the right fuel mixture: Fuel = Gasoline Oil

Oil. high-quality, two-stroke oil for high-speed equipment (10-15 thousand rpm). rpm, about 200 rpm). Do not use motorcycle oils (low engine speed) or water-based oils (different cooling system). their use does not provide the necessary lubrication for piston groups and engine parts! You can use, for example, Husqvarna, STIHL or Champion oils.

Gasoline. any pure high-octane gasoline (number 92 or higher, with a density within the limits of 750-770 kg/m3). The purity of the gasoline must be:

The first start of the grass trimmer

When everything is checked and the prepared fuel mixture is poured into the tank, it is time to start the grass trimmer for the first time before running it in. To do this, you need to perform the following manipulations:

  • Position the brushcutter on a level, horizontal surface;
  • Move the choke control lever to the closed position;
  • Pump a few pumps of primer fuel into the carburetor;
  • Turn on the ignition tumbler;
  • Gently pull the starter cord until you feel resistance;
  • After starting make 3 4 jerks with the cord until the lawnmower starts;
  • After starting, open the air damper.

In case the lawnmower does not start or stalls the first time, slightly open the choke on the carburetor and try to start again.

Basic mistakes during start-up

Why the device does not start well, overheats? If such problems occur, it is recommended that you:

  • Check the volume of mixture in the tank.
  • Choose a quality fuel when buying.
  • Prepare the mixture according to the recommendations, instructions.
  • Change the position of the air bags. With the choke closed and 5 jerks, fuel may pour into the spark plugs.
  • Turn the ignition off when starting. The ignition is most often started immediately after the choke shutters are closed.

What you need to know before using your new lawnmower

After buying a lawnmower, the question arises how to properly assemble this construction, since many models are delivered in a disassembled form.

Here are the detailed instructions on how to assemble a classic lawn mower.

  • Unpack the parts and connect the unit with the motor and the boom as shown in the instruction manual. The kit usually comes with a set of hex wrenches.
  • Put the handle on the boom. To do this, unscrew the bolts on the clamp and place the handle in it. Bicycle models are mounted so that the throttle trigger is on the right side. Tighten the bolts.
  • Assembling the cover. We install the knife (if there is in the set) and screw the hood to the boom with a special fastener.
  • Installing the trimmer head. We unclamp the washers and fix the head by the side opening (pull the thin wire or bar to stop the head twisting). Unscrew the rear threaded nut.
  • Installing accessories. To secure the line, remove the conical washer and leave the flat washer. Then put on the cord reel and tighten. To attach the blade or disc, you need to remove both washers, put the blade on and close everything with a tapered washer and tighten the nut.

How to run the lawnmower correctly

Before starting the lawn mower, you must run the engine. This is to prolong the life of the machine, as the mechanisms must be well lapped to each other for smooth operation. In addition, you will know better how the lawnmower works from the inside and get the necessary skills to work with it.

Before starting the engine, you must lubricate the gearbox and prepare the correct fuel mix. How to prepare fuel for the running-in period,

Advice on how to run the lawnmower new or at the beginning of the season.

  • Use the following proportions for the fuel mixture when you start: 40 ml of oil per 1 liter of gasoline. It is necessary to fill the first 5 full gas tanks with this kind of mixture and then use the standard ratio given in the technical data sheet.
  • Do not run the engine at high engine speeds for a long time.
  • Work only with the engine warmed up, do not allow overheating.
  • Change the oil completely after the run-in.
  • Open the throttle to the maximum the first time the engine is running.

If you observe these rules, you will get the engine running in the most sparing mode and quality lubrication of the piston group. This will ensure the longevity of the lawnmower.

Important! In the beginning you may notice a small accumulation of oil in the muffler, which has not had time to burn. This is due to its high content in the fuel mixture. After the run-in period, change the oil-to-gasoline ratio to the normal oil-to-gasoline ratio for the model and the problem will disappear.

How to start the lawnmower

First of all, prepare the fuel mixture in the proportions as indicated in the data sheet. It is convenient to buy a special canister with two compartments for gasoline and oil.

Starting with a cold engine

  • Turn on the ignition.
  • Close the air damper and press the fuel button several times.
  • Put the mower on a flat surface and pull the starter cord gently until you feel resistance.
  • Pull the cord out quickly and several times.
  • Open the air damper.

Start with engine warmed up

Turn on the ignition and pull the cord until the engine starts.

Important! Do not start the engine with the ignition off! Do not use a fuel mix with the wrong proportions of gasoline and oil. Do not jerk start the machine more than 5 times if the choke is closed.

How to wind the filament on the lawnmower

Winding new cord onto the spool is a fairly easy process. You’ll need a reel of new fishing line of the right diameter and shape, a paring knife, and protective gloves for the job. The following is a diagram of how to change the line on a spool with 2 tendrils, as this is the most common version.

  • Cut a 2-4 m length of fishing line (the length of the cut depends on the thickness of the cord and the manufacturer’s advice). Do not use a longer cord as it will be less likely to rotate and pull out when you mow.
  • Remove the trimmer head from its mounting (each model has a different mounting method: with special clips or with a wing nut) and disassemble it. Accurately spread out all the parts next to each other without losing anything.
  • Wind the line on the spool. There are 2 types of spools: with or without a spacer bead.

Spool with spacer bead

  • Fold the line in two and put the fold over the groove in the spool. If you do not have one, simply cut the cord in two pieces along the line bend and fasten the ends in the holders.
  • Thread the ends into the special grooves on each part of the coil.
  • Start winding the remaining length of cord to one side.
  • Leave 20 cm on the ends and place them in opposite directions, pulling them through the special holes.
  • Cut the cord to the desired length in half.
  • Fix the tips in the coil in special mounts or extend into the holes.
  • The direction of winding is indicated on the bobbin, in which direction the cord must be wound. Wind it up without letting the sections cross over on the spool.
  • Place the ends on opposite sides and insert them in the slots provided. The diameter should match.

Important! Buy the branded cord that is recommended for your model of lawnmower. It is stronger than cheap counterparts and will last longer. Also pay attention to the diameter of the holes in the spools with a separating bead, so that you can find a line of suitable cross section. Do not wind the line tightly but wind it loosely while working.

To wind the line on a spool with 1 cutting end, do not fold the cord. For mowing heads with 4 spools of line, prepare 4 pieces of line. The winding scheme is the same as described above.
