Increased attention to operator safety is evident in the form of an emergency duty cycle status and a palletized mains switching system. The improved air cleaning system extends filter life without additional maintenance, and the high degree of vibration absorption makes the work process even more enjoyable for the operator.

Base equipment and chainsaw assembly

Safety precautions when working with a chainsaw

The chainsaw must be operated with both hands only. How to do it properly, you can see on numerous videos. It is imperative to protect the organs of the headphones, goggles and mask from dust, tires and chips. Also, do not forget to use protective gloves, outfitted but not restrictive clothing and closed, comfortable shoes.

Before starting work, check that the emergency stand is in good working order and that both fuel and oil are in the tank. The manufacturer does not recommend using the chainsaw in closed rooms, because the gasoline engine creates emissions for the operator.

In case of breakdowns or malfunctions, repair and maintenance can be carried out independently, for which purpose, carefully study the operating instructions and watch a video on how to assemble and disassemble the chainsaw Partner. However, the manufacturer itself insists on high, professional and qualified service in service centers.

Partner chainsaws operating instructions and maintenance

How to properly maintain the saw on the gasoline drive, how to adapt the carburetor, pull the chain, what fuel tank and what type of oil is used for lubrication, the main faults and the possibilities of their solution are used in the instructions to the chainsaw Partner 350 . You can study it electronically: Here:

Fuel mixture and oil for the partner 350 chainsaw

In the instructions, the manufacturer recommends using unhealthy gasoline mixed with special engine oil, which is designed for two-stroke engines. In reviews and videos, users of the Partner 350 chainsaw are often reminded of the importance of maintaining the ratio of gasoline to oil: 1 part oil to 40 parts gasoline. Pure gasoline should never be poured into the fuel tank. It can cause serious structural damage to the engine.

Air-cooled, premium quality oil for two-stroke engines should be used to lubricate the chain. It is also important to maintain a 40: 1 ratio. Neither the video nor the instructions recommend the use of oil lubrication, with a mixture ratio of 100: 1. The fact is that the engine quickly fails if the chainsaw does not receive sufficient engine and chain lubrication, and carries significant information that is not covered by the warranty.

Major chainsaw deformities and troubleshooting

The main problem faced by users and solutions in videos and reviews is that the engine won’t start. The reasons why the Partner 350 chainsaw won’t start are as follows:

The chainsaw engines were not started correctly.
The mixture proportions in the carburetor have not been maintained;
The spark plug or fuel filter is dirty.

To find out where the cause is, try disassembling your Partner 350, check your chainsaw settings, and correct any problems you find.

If the chainsaw isn’t working everywhere or if its functions are unstable, try changing the spark, cleaning the air filter, or adjusting the carburetor. You can see how to properly tune the carburetor in the video below.

In this case, if your chainsaw is unstable and emits a strong, smoky exhaust when running, you’ve probably got the fuel to oil ratio wrong. Try replacing the fuel mixture with a new one.

EGOR:

The value for money and quality of this chainsaw is top-notch. An inexpensive model with relatively good materials, build and saws. Before I started, I watched some instructional videos and worked on the air filter seal. Partner 350 was designed for cottage, some domestic work that does not require super-powered professional saws

Oleg:

I bought my partners 350 for my country house, to cut firewood, do small construction jobs, saw deadwood, etc. With proper care and maintenance chainsaw works perfectly and without problems. If you have decided to buy this machine, carefully and thoroughly read the manual and watch the additional video, so as not to write bad reviews later. I am more than satisfied with the quality of the saw itself and your work.

Advantages: sensitive quick start system, comfortable controls, sharp chain, no fuel or oil leakage. Maneuverable and ergonomic saw with a stable spar.

Disadvantages: The plastic is not of the best quality, but I do not consider it a significant disadvantage for the money. To get to the filter, you need to unscrew the screw.

Light the garden

To analyze the situation more accurately, do the following:

- Check that fuel is flowing into the carburetor – if not:
  - Saw’s gas tank is empty:
  - Swim needle is blocked;
  - No air in fuel tank;
  - The gasoline filter is clogged. These faults are corrected by cleaning the cleaning systems and filling the chainsaw with high-quality fuel.
  - If there is no spark after connecting to the ground wire, the problem is with the spark plug itself, which most likely needs to be replaced. In addition to the spark plug, other parts, such as the coil or ignition switch, often fail;
  - Recognizing a wet spark plug is a sure sign that the plug is primed. It can have the following causes:
    - Incorrect or improper factory carburetor settings;
    - Filling the carburetor block with fuel.
    Adjusting the carburetor
    
    If the chainsaw partner poorly starts, smokes heavily and does not meet the manufacturer’s stated characteristics, the question of how to adapt the carburetor of the chainsaw partner 350, should become the main for each user. To solve it:
    - Warm up the engine;
    - Twist the L screw to the stop, then loosen it by a quarter.
    - When the saw breaks down, twist the nozzle t;
    - For proper operation of the chainsaw Partner undermine the screw with maximum revolutions.
    A universal wrench and rotary knife (rotating crankshaft knife) are desirable for installation. The power and ignition settings are set at the partner’s factory. Therefore, a completely new saw is not required for rewinding.
    
    Malfunctions in the oil supply system
    
    A situation in which the chain lubricant flows inadvertently from the chainsaw body and does not reach the cutting parts does not indicate a need to repair the oil pump, clean the oil tube or replace it with a breathtaking replacement part. In addition, the lubrication current may indicate that the tubing connection to the oil sump is broken. If these breakdowns are not corrected in time, the chain begins to overheat, stretch and fail prematurely.
    
    Repair of the chainsaw “Partner” 350 with their own hands should be carried out only by people familiar with its device and the principle of operation. Only then we can hope that the replacement of the drive sprocket or crankshaft will be carried out correctly and safely for further work.
