Chainsaws Partner (Partner) - models and characteristics

Chainsaw device Partner

Each saw is powered by a reliable 2-stroke gasoline engine equipped with a forced air supply system. The motors used by the manufacturer are distinguished by their reliability and ability to operate properly under variable and constantly high loads. A solid reserve of torque makes it possible to use saws to perform various household and industrial tasks.

To start the engine, each chainsaw is equipped with a manual starter with an easy start function. This makes it possible to easily start the tool at very low temperatures. The fuel mixture is ignited using a proprietary spark plug and electronic ignition. A durable clutch is responsible for transmitting torque from the internal combustion engine to the tire.

All parts and mechanisms of each saw are placed in a reliable plastic case. It is made of multi-layer polymers, which gives it the ability to withstand accidental impacts and falls from low heights. The manufacturer has provided free access to filters and other frequently replaced elements. This greatly simplifies the DIY repair of the Partner chainsaw.

The Partner is responsible for sawing wood in each chainsaw using a proprietary bar and chain. The saw set operates under the control of an oil pump, which automatically supplies oil as the chain moves along the bar. When the headset hits a nail or any other hard object, the inertial brake is activated, which makes the tool completely safe for the operator.

Each Partner model stands out for its ease of use. The front and rear handles of the tool are covered with high-quality rubberized material, which prevents the operator’s hands from slipping during operation. The tool's effective anti-vibration system dampens strong engine vibrations. This makes it possible to use a chainsaw both on the ground and at height without feeling tired during its operation.

Adjusting the carburetor of a chainsaw Partner

Over time, every Partner chainsaw owner is faced with a deterioration in the operation of the tool’s internal combustion engine, as well as a sharp increase in the amount of fuel it consumes. The first thing to do in this case is to adjust the carburetor on the Partner chainsaw.

Immediately before tuning, you will need to clean the carburetor and all parts located next to it. You also need to wash or replace the air and fuel filters. After this, you will need to find 3 standard holes in the upper part of the protective cover of the tool. Inside them are adjusting bolts marked H, L and T. The letters are always indicated on the protective cover of the Partner chainsaw. The right bolt marked H is needed to adjust the quality of the fuel mixture. Accordingly, the left screw is designed to adjust the amount of fuel supplied, and is designated by the letter L. The third screw has a small spring on it. It is designated by the letter T, and is needed to adjust the position of the throttle valve when the engine is idling.

Setting up the Partner chainsaw carburetor is performed in the following order:

First, with the saw motor turned off, bolts H and L must be completely tightened clockwise, and then immediately unscrewed 1/5 of a turn in the opposite direction;
Then you need to start the engine of the tool and give it time to warm up. As soon as the engine warms up, you will need to start turning bolt L until the internal combustion engine reaches maximum speed. Immediately after this, the bolt must be turned 1/4 turn in the opposite direction. If the idle speed of the engine is too low or very high, then they should be adjusted with screw T;
Next, you need to connect a tachometer to the saw motor. After this, you will need to start turning bolt H until the engine reaches its highest speed. If the readings on the tachometer coincide with the instructions in the instructions for the tool, then you can proceed to the last stage of setup:
At the end, you need to make sure that after all the actions the saw chain does not start moving along the bar. If the headset moves, you will need to start turning the T screw in different directions. As soon as the chain stops moving, you can turn off the saw engine.

After adjustment, you need to start the tool again and check the operation of its engine. To do this, you need to press the gas trigger several times, increasing the load on the engine. If the internal combustion engine steadily gains and loses speed, it means that the carburetor adjustment of the Partner saw was completed successfully.

Setting up the carburetor

The Partner 351 chainsaw has several operating mechanisms that require periodic inspection and maintenance. One of them is a carburetor.

It is not recommended to repair the carburetor of the Partner 351 chainsaw with your own hands, but it is possible to make minor adjustments. There are two main breakdowns that can be fixed by adjusting the carburetor yourself:

The chain spins while the engine is idling. To correct the problem, use the adjusting screw. First, turn it completely clockwise. Then make 4.5 turns counterclockwise. The fault should disappear.
Incorrect supply of fuel mixture. There may be several reasons. From unbalancing adjusting screws to breaking carburetor parts. In any case, the adjustment follows the same pattern.

To adjust the carburetor, there are three adjusting screws: L – for high speeds, H – for low speeds, T – idle speed of the Partner 351 chainsaw.

The adjustment begins with screw T. To do this, start the saw and turn the adjusting screw counterclockwise until the chain stops.
Then turn screw L a quarter turn counterclockwise. During adjustment, the idle speed should have the largest turns.
Screw H is turned a quarter turn counterclockwise.

After these manipulations, a tachometer is taken and the revolutions are checked. They should correspond as much as possible to the speeds indicated in the passport of the Partner 351 chainsaw. If you still decide to adjust the carburetor of the Partner 351 chainsaw with your own hands, we recommend reading the article about adjusting the carburetor on a chainsaw. This general article contains all the necessary information and will greatly help you in this difficult process.

How to set the ignition on a Partner chainsaw?

Before setting the ignition, you will need to make sure that the spark plug is working properly. If it is not filled with the fuel mixture, and no traces of soot are visible on it, then you can start tuning. All subsequent actions boil down to adjusting the gap between the flywheel and magneto. The algorithm of actions is as follows:

First you need to take measurements of the current gap between the two elements. For stable operation of the ignition system, it should be no more than 0.2 mm. If the gap is too large, then it needs to be adjusted;
To do this, you will need to find 2 screws near the flywheel. By turning them, the flywheel will move away from the coil;
Moving the element a little, you need to install a template between it and the coil. After this, you will need to start turning the screws in the opposite direction until the flywheel comes close to the magneto. Then you need to remove the template and assemble the chainsaw.

As a result of a correctly set gap, problems when starting the Partner chainsaw will disappear. The engine will start quickly and reliably, both cold and hot.

Conditions for self-repair of chainsaws Partner

It is possible for the owner of the tool who has the skills to repair household appliances to fix the malfunction independently after the end of the warranty service. First you need to learn the technique. Experienced craftsmen believe that repairing a Partner 350 chainsaw with your own hands begins with correct diagnosis. To determine the nature of the repair, you must:

check the ignition system;
perform diagnostics of carburetor operation;
fuel system efficiency;
clean the muffler;
determine the performance of the piston system;
check chain lubrication;
determine the wear of components and the required spare parts for the Partner chainsaw.

Complex issues must be resolved with the involvement of specialists for consultation.

If the engine refuses to start, first of all check whether the spark plugs are working properly. They must be dry and have a contact gap of 0.5 -0.65 mm. Based on the condition of the unscrewed spark plug, you can determine signs of problems in the fuel system and equipment operation.

Check the serviceability of the spark plug by connecting it to the starter through the cap and placing it on the cylinder body. The spark plug is good if it produces a spark on the housing when the starter is pulled. If there is no spark, the wire is faulty or the spark plug is flooded or has expired.

A saw that has been used a lot may experience carburetor malfunctions. But first you should adjust the carburetor of the Partner 350 chainsaw, as shown in the video:

Repairing the carburetor can temporarily extend the engine's operating time. The passages in the carburetor can become clogged with low-quality fuel or through a leaky air filter. When disassembling the unit, it is necessary to wash and blow through all parts.

It is better to entrust the repair and adjustment of the carburetor, as the most critical component, to a specialist.

If fuel does not enter the cylinder:

You can clean the fuel filter after you have made sure that the fuel flow from the hose is low. Depending on the degree of blockage, it needs to be cleaned or replaced with a new one.
If the injection is clogged, remove the hose and clean the hole with a needle.
Not enough air enters the carburetor through a clogged air filter. The supply of mixture to the engine is disrupted.
Incorrect carburetor adjustment will lead to the same result.

The chain is not lubricated. To avoid overheating of the chain and its pulling, lubricant must be supplied to the working unit automatically. But since the oil is supplied through the channels, they can become clogged with fine wood dust. After each cycle of work, the canvas and gaps must be cleaned of dust and dirt. If oil is leaking, you need to check the integrity of the hose and the tightness of the connection to the tank. Replace the faulty hose or temporarily cover the hole with sealant. Repair the oil pump.

Malfunctions of the Partner 350 chainsaw include failure of long-term use parts. If the sprocket, tire, rubber anti-vibration seal is worn out, or the chain becomes dull, you need to take action in a timely manner. In harsh operating conditions, they must be under control, replaced, sharpened, and tightened on time.
