How to disassemble Parma electric saw. Frequent malfunctions

saw electric chain assembly Parma M3 Repair

Parma electric saws are produced in two types, each of which has its own design features, purpose and operational characteristics. In this case, we are talking about proven and reliable chain models and no less strong disk samples. The former replaced the once popular gasoline devices and borrowed the main nodes and aggregates from them.

Such models are arranged quite simply: they consist of a durable case with an electric engine built into it, a saw tire equipped with a cutting chain, a stretch mechanism and a chain lubricant system.

The principle of operation of the Parma chain saws is to transmit torque from the engine to the cutting circuit using a gearbox and a leading award. Simultaneously with the engine, an oil pump starts, which supplies lubricants from an oil tank onto the tire and supports the moving parts of the tool in working condition. Unlike gasoline models, Parma electric saws do not have a clutch, carburetor and air filters, which is why they require minimal maintenance and do not need to be adjusted.

All models of the Parma electric saw are equipped with a chain brake that turns off the engine when tires contact with solid objects. The brake drives a protective shield installed in front of the working handle. When hitting a nail, the saw is thrown up, and the operator involuntarily hit the protective shield. The engine is turned off instantly, so it is impossible to injure from contact with the cutting element.

In addition, many devices have a smooth start function that protects the engine winding from overheating and prolonging its life. Also, chain saws include a chain tensioner, which is driven by both using a special handle and by means of a wrench.

How to protect yourself from fakes

The more popular the technique, the more frustrated the market of the product of an incomprehensible property with the corresponding brand logos will be flooded. It is not necessary to recognize a fake before making a purchase. Subsequent deeds help to identify the falsify:

  • High.quality colorful packaging confirms the authenticity of the tool, measured colors, cheap cardboard indicates a reverse.
  • On the pages of the manufacturer’s website, a catalog of unique products is presented with proper descriptions, features and photos, look at the website and compare the proposed PARMA electric saw with the original.
  • We check visually the quality of casting, assembly, adjacent parts. porous structure, measurements and gaps between the details are required to be suspicious.
  • We read the bar code, it will give information about the tool, manufacturer and the country of production.

Electric saw chain “Parma” 2m

Electric saw mass 5.6 kg. Power of the transverse email. engine 2000 watts, power from the mains 220 V. This is an advanced modification with an automatic chain, which of course simply regulate. The oil tank is equipped with an observation window, allowing visually control the censor of the tank with lubricants.

The manufacturer perfectly balanced the tool, taking care of lowering the fatigue of the operator at the time of long.term work. Blocking the chain, motor, upper protection allow you to make the necessary safety conditions during operation. A saw set is used: a guide tire 40 cm long and a saw chain for 57 links.

Electric saws are an indispensable tool in a summer cottage or in a private house. She easily copes with the cut of thick branches, boards and various wood material. Even the most reliable tool has its own degree of wear, it is periodically required to correct small or large breakdowns. Do.it.yourself repair of electric saws is possible only in some cases and in the presence of certain skills and tools. Often the tool has to be given to the service. But there are some breakdowns that are easily corrected independently.

Review of the design of the chain electric saw

In order to master the repair skills of electric saw, it is necessary to understand their design. The main element that cuts the material is the saw chain, which is driven by the motor. The chain itself is a combination of cutting links, which are fastened with each other. The movement of the chain is made according to the plate called the bus. This part of high.quality steel is made, which is not susceptible to chips, scratches and corrosion. this is the main indicator of the quality of the tool. The tires are distinguished by the designs:

disassemble, parma, electric, malfunctions

The welded tire is something similar to a “sandwich” that is welded from three components into one, while a driven star is glued into the structure. A whole design with a change of tip is a product from one sheet, optimal for tool tools. In such a tire, the main load lies on the roller bearing of the driven star. The whole configuration allows you to reduce friction loss by 8-10%. If a tool with a solid tire made of solid alloy materials, then it is optimal for working with high load, as well as for operation in conditions of a large amount of sand, dust and dirt.

When working with an electric saw of any configuration, it is necessary to remember the possibility of a “reverse blow”. the tool to take the instrument in the direction of the person performing the work of a person. This situation arises if the very end of the saw tire rests against the processed material. To avoid injuries in such a situation, manufacturers equip the saw with an automatic chain brake.

The automatic brake of the chain is also called inertial drives, which works thanks to the shield in front of the left hand performing the work of a person. Before starting work, this shield is placed closer to the hand, so that, if necessary, it is quickly driven. If the moment of the reverse blow occurs, then the operator’s hand rests against this shield and the chain stops. The position changes and due to the impact of inertia. Such a system allows you to reduce the likelihood of repairing chain electric saw, since during the impact of its main mechanism will not be damaged.

Another system that prevents wear and breakdown is automatic lubrication of the chain. In a special tank, oil is poured, which is transmitted through the oil pump to the leading star and chain during the operation of the saw. Some models even have an oil supply controller, since with different intensity of work it is necessary for a different amount of its number. For example, Makita electricity repair involves inspection of the oil supply system.

Chain saws with an electric motor have some disadvantages or weaknesses. One of them is the design of the gearbox. The torque is transmitted to the chain through a gearbox, which has a hard bunch with an anchor of an electric motor. This design transfers all the loads to the motor, that is, if the workpiece contains hard inserts or the saw chain is dull, then it will not slide so smoothly along the surface. The result of this will be overheating of the motor or wear of some of its details. As a preventive measure, it is necessary to sharpen the saw in a timely manner and not put pressure on it during work. Often enters the service repair of Parma electric saw with this kind of fault.

Do.it.yourself chain electric saw

Equipment cannot work forever. one day you will have to maintain and repair chain power saws. To get rid of “low blood”, do not overpay or carry equipment to the service, use simple instructions!

We examined the most common problems:

Why is the oil pump breaks, how to fix it

The lubrication of the circuit should be carried out regularly, but sometimes the oil pump fails. The fault of everything is incorrect adjustment!

If the plunger is twisted a little stronger, the fist of the eccentric of the gear shaft can break it. In new saws, everything is already adjusted and ready for work. But if you have already worked and the oil has stopped supplied to the right volume, watch the video and check the plunger.

How to repair a chain

The saw chain breaks and breaks very often. it is important to make an editing strictly according to the template so that the equipment serves longer.

Everyone got used to working with one chain. they put it, worked, threw it out. And then put a new one on a worn star. Because of this, the step does not coincide, and the chain stretches from this.

A simple way to avoid this: purchase 1 asterisk and 3 new chains and periodically change them during operation. So, the chains will wear out evenly and last much longer.

Why is the stator burn, and how to avoid this

Do.it.yourself electric saws should be carried out strictly according to the instructions. Typically, problems are caused by violation of the assembly technology of the electric motor.

The new stator burns out for several reasons:

  • Too long bracket bolts can break through the stator
  • Dressed bolts of normal length
  • Bluted sewage planting (backlash)
  • Broken fan blades and the appearance of vibration
  • Unexpected screw

Also, when replacing the stator, it is important to check the degree of wear of the bearings. the landing should be dense.

Service of the saw

Before working with the electric saw, the owner needs to carefully read the factory instructions, understand security measures, study work methods, schedule of regulatory work, recommendations for eliminating malfunctions and breakdowns.

Before starting, it is always necessary to check the voltage in the electric network, test the lubricant system and the amount of oil. Tire, asterisk, saw chain are subjected to increased loads, so the oil level. both before starting and during operation, should always be higher than the indicated mark.

The lack of oil is extremely negatively affected by both the saw and the service life. The chain should only be lubricated with high.quality original oil or suitable by the characteristics of the viscosity of analogues, in accordance with the season of work, taking into account the state of wood. wet or wet. It is extremely unreasonable to use working out or other, supposedly “proven”, dubious lubrication recipes.

The main malfunctions and types of repair

Proper operation and maintenance of Parma-M5 electric saws is a prerequisite for the long-term stable operation of the tool. The manufacturer recommends taking into account the following features:

  • It is necessary to strictly comply with the rules for safe working with an electric tool.
  • Since the saw engine is not moisture.proof, it is forbidden to work in raw wet weather, rain, otherwise, the breakdown of the motor is inevitable.
  • Select an extension cable with the corresponding cross.section of the cable, with an increase in its length over 30 m, the efficiency of work is reduced.
  • It should be performed exclusively by those of the saw maintenance that are prescribed by the instructions, use only original spare parts. Sharpening of a saw, replacement of nodes, complex repairs is advisable to entrust the service specialists. Installation of an inappropriate saw headset, disassembly of Parma-M5 electric saws can lead to breakdowns, the occurrence of unforeseen situations. It is prohibited to disassemble the saw yourself during the period of the warranty period.
  • If the electric saw does not turn on, check the presence of voltage in the network, test the condition of the cable, sockets, whether the circuit brake is turned on.
  • If the chain stopped stopping instantly, defects in the friction clutch have appeared possible.

  • If the saw does not turn on, it is necessary to check the presence of power, the integrity of the wires and connections.
  • If everything is in order in the power supply, you need to check the brake of the chain that blocks the operation of the tool. To eliminate this problem, it is necessary to move the brake panel to another position.
  • If the measures described above did not turn on the saw, then it is necessary to check the integrity of the cable and the plug.
  • If the saw capacity has decreased, performance has fallen, it is necessary to replace the coal brushes, which, apparently, have worn out.
  • Quite often the chain does not stop immediately, but after a certain period of time. The longer the saw is operated, the more this time period becomes. To get rid of this problem, it is necessary to replace the drain brake tape, which was worn out after time.
  • Often an unpleasant, cutting ear sound appears in the work of the saw. Such a sound often appears due to a lack of oil in the mechanism or due to contamination of the grooves conducting it. Eliminate the malfunction is simple. pour oil and clean the furrows.
  • It is important to use only original spare parts when repairing, which are recommended by the manufacturer. If you use spare parts from third.party firms, this often leads to breakdowns of the tool or the occurrence of dangerous situations.
  • If there are damage to the case, then for the sake of your own safety, the saw must be handed over for repairs.
