Chainsaw Partner 350 repair manual. Chainsaw partner 350: malfunctions and their elimination

One of the main features of this saw, its users note the durability of operation with a minimum number of failures.
And yet they happen. To determine why the saw stopped working, you need to make an elementary diagnosis. If the saw does not start, then:

• there is no spark on the candle;
• fuel is not supplied;
• no air enters.

First you should check for a spark: unscrew the candle, attach it to the high-voltage wire and put it on the cylinder, pull the starter. If there is a spark, then clean and adjust the gap on the candle (0.5 - 0.65 mm). If it is not there, then you need to change: either the flywheel or the coil (magneto). In addition, the candle itself may fail or the high-voltage wire may be interrupted.

The next step is to check the fuel supply. To do this, disconnect the supply hose from the carburetor and check its presence. Absence may mean that the fuel filter or supply system is clogged. And the carburetor itself may become clogged.

If you do not have experience in repairing and cleaning it, entrust this work to specialists.

If the air supply deteriorates, the saw should start, but it will work poorly. Remove and wash the air filter. Put it in place only after complete drying.

If the saw starts well, runs at idle and stalls when gas is supplied, the muffler is most likely clogged. Remove, disassemble, wash, put in place and work on.

You can also easily change the saw bar and chain, carburetor, starter, oil pump, ignition and clutch with your own hands.

And you will be quite capable of replacing a broken starter cable after watching this video:

We recommend entrusting more complex chainsaw repairs related to replacing the cylinder-piston group or crankshaft to specialists, although if you are familiar with two-stroke engines, this work will not be difficult for you, and spare parts for Partner chainsaws are not in short supply in Russia.

If there is a spark, clean and adjust the gap on the spark plug (0.5 - 0.65 mm). If this is not the case, you need to change: either the flywheel or the coil (magneto). In addition, the spark plug itself or the high voltage wire may break.

The next step is to check the fuel supply. To do this, disconnect the supply hose from the carburetor and check its presence. Missing may mean that the fuel filter or supply system is clogged. And the carburetor can also be clogged.

Easily with your hands, you can also change the saw blade and chain, carburetor, starter motor, oil pump, ignition and clutch.

Algorithm and description of the disassembly process

If you need to completely disassemble the Partner 350 chainsaw, the first thing disassembly begins with is cleaning the saw with a compressor. Next, the chainsaw nodes are removed in the following order:

• chain brake cover and saw set;
• top cover;
• saw handle;
• starter.

After the first stage of disassembly is over, we re-clean the chainsaw with a compressor, since we already have access to the air ducts, which in most cases are heavily polluted with wood dust.

In the next step, it is convenient to remove the air filter housing and Partner 350 carburetor.

After removing the carburetor, the cylinder inlet port must be plugged with a rag, this will protect against foreign objects entering the engine crankcase.

The muffler can be removed either immediately after the carburetor has been removed, or after the engine has been removed. The outlet window is also closed with rags.

Next, remove the clutch and flywheel.

To do this, you will need to use a piston stopper by installing it in the candle hole.

The clutch on all Partner 350 chainsaws is unscrewed in the direction of the chain, this is done so that it does not unwind during operation. The flywheel nut has a standard thread and is unscrewed with a socket by 13, counterclockwise.

After removing the clutch, access to the oil pump appears, it must also be removed.

At the last stage, you need to unscrew the screws of the engine and remove it from the case.

Instructions for removing the flywheel from the crankshaft

To remove the flywheel, you will need to use a special puller, but most craftsmen use a soft metal drift, because with its help the removal process is greatly accelerated.

The bottom line is that the flywheel nut is unscrewed until it is level with the plane of the shaft, after which, using a hammer and a punch mounted on the nut, with one sharp blow, the flywheel is removed from the shaft.

The method is a bit barbaric, but time-tested and recommended by many masters as the most practical and reliable.

Chainsaw Partner 350 Starts and stalls. Similar posts

Why does a chainsaw stall when you press the gas?

Hello! If you ended up on this page, then, most likely, your chainsaw stalls when you press the gas, and you want to find out why this is happening and what to do about it. Whatever, I will try to help you in this dilemma, having analyzed the most common prerequisites for such damage, as well as ways to eliminate them.

To begin with, I’ll write right away for novice users that many chainsaws require the engine to warm up at idle for about one minute before work. Why does a chainsaw start and stall - reasons and Here the chainsaw stalled and does not start or the chainsaw stalls stalls. Until the engine is warmed up, the saw may stall when gas is added.

So, if a warm chainsaw can idle, but stalls under load, this means that:

• incorrectly configured or clogged carburetor - the most common case;
• it lacks air, the consumption of which increases sharply with increasing speed - this means that the air filter is dirty (the rarest case, because the filter is dirty evenly, because the user first notices the loss of power);
• she lacks fuel, the consumption of which also increases with increasing speed - this means that the fuel filter is dirty (also an infrequent case);
• well, and the worst case, if there is excessive friction between the piston and the cylinder wall, associated with a lack of oil in the fuel mixture - after such operation of the chainsaw, you will most likely fly into the repair of the piston group, because on the piston and cylinder walls, blockages are formed that prevent saw work.

Let's analyze these cases separately.

Troubleshooting common problems

The Partner 350 has popular faults that owners of these saws can diagnose and fix on their own. Let's take a closer look at popular malfunctions and how to fix them yourself.

Silences when you press the gas

If the Partner 350 stalls when you press the gas, then most likely there are problems with the fuel system. The most common failure is an incorrectly adjusted carburetor or its malfunction, as well as extraneous air leakage.

Tip: If the chainsaw stalls with increasing speed, do not immediately adjust the carburetor. Start by checking the engine for foreign air leaks. One of the signs of air leakage is increased idling.

Runs and dies

If the Partner 350 starts up and immediately stalls, then, as in the previous case, there may be several reasons, but the most common is a difficult fuel supply. It is worth starting troubleshooting by checking the condition of the fuel filter and lines. If fuel is supplied normally, then check the spark and try to start the chainsaw on a new candle, as the saw may stall due to interruptions in sparking.

It is also necessary to check the draft of the air damper. If it does not open the choke or does not open fully, then the engine may stall from excessive fuel enrichment.

Lack of chain lubrication

There are several reasons for the lack of lubrication on the Partner 350 chainsaw, and in this case we can list them all.

1. Oil line break.
2. Clogged oil filter.
3. Worm gear defective.
4. Clogged line or pump.

How to solve oil pump problems is described above.

Pouring a candle

A very common problem that Partner 350 owners have to face. The first thing to start with is to replace the spark plug with a known good one. If it doesn’t help, the spark is good, but the engine floods, then the reason is hidden in the carburetor settings. Instructions for diagnosing and setting up a carburetor for Partner 350 are on our website.

Chainsaw Partner 350 does not start. How the mechanism works

In fact, all tools, both foreign (Huskvarna, Makita, Shtil, Partner 350), and Chinese chainsaws, and Russian ones (Druzhba, Ural), are identical. Partner 350 chainsaw won't start. Therefore, it will not be difficult to find the reason why the device does not start and stalls.

There are four elements in which difficulties may arise:

• Fuel for which the carburetor is responsible;
• Lubricant;
• The air that enters;
• A spark, the quality of which depends on the ignition unit.

All of them depend on each other and interact with each other. If any element does not work correctly, then the saw stops working.

Let's start with the fact that all tools start up differently - hot and cold. Two commonly used mechanisms are responsible for this process.

Be sure to see what is written in the user manual. It says that when you turn it on, you need to make sure that the emergency stop brake is locked. But it is much more difficult to start a saw with a brake, so sometimes it is better not to apply the brake.

As you can see from the instructions, inside the case there is a fuel tank and an engine, and outside there is a saw part (tire with a chain), a handle and a starter.

First you need to figure out exactly how the tool does not start. For example, the saw starts, but immediately stalls, or it loses the power of work, the quality of the cut.

Perhaps interruptions in operation occur due to problems in the engine. Stihl (stihl) chainsaw does not start: how to start. But I would not recommend disassembling it right away.
