Chainsaw care and maintenance

Jonsered chainsaws are built to survive tough challenges, but they do need some looking after to work safely and efficiently. Here are a few easy tips.

You can do most maintenance yourself using the instruction manual. Your Jonsered dealer has all the spare parts and accessories you need and will also be happy to assist you when it’s time for service.

After every shift

Check the chain tension and lubrication. Retention the chain and top up the chain oil if necessary. Get into the habit of refueling the saw before you put it away for the evening. That way it will always be ready.

At regular intervals

When the air filter starts clogging up with sawdust you should remove the filter and wash it in a little tepid water and mild detergent. How often you need to do this depends on how much you use the saw.

Jonsered’s unique turbo air cleaning system removes most of the sawdust from the intake air before it reaches the air filter. This means you do not need to clean the air filter on a Jonsered turbo saw as often as with most other chainsaws.

Now and then you should also blow the sawdust and dirt out from the cooling fins and the brake band.

How to cross-cut a trunk with a chainsaw

Think ahead before you begin to cross-cut, especially if it is a large trunk. Where will the next length fall when you cut through it? And what will happen to the rest of the tree when you cut off a large, heavy length?

Start by gripping the front handle with your left thumb and apply full throttle before you begin to cut. Stand diagonally behind the saw while you work, not directly behind it.

If the trunk is supported at both ends

If you try to cut the trunk from above when it is supported at both ends, the cut will close up and trap the saw. This is why you must always cut the trunk from below. First make a shallow cut in the top of the trunk above the cutting point to prevent the trunk from splitting.

If the end of the trunk is unsupported

If the end of the trunk you intend to cross-cut is suspended in the air, you must cut it from above to avoid trapping the saw. But first make a shallow cut in the underside of the trunk at the cutting point to prevent the trunk from splitting.

If the saw becomes caught in the cut

Sometimes it can be hard to judge how a log is lying. If the saw becomes caught you must never try to shake the saw free with the engine running. You could injure yourself and damage the saw. Instead you should stop the engine and prize open the cut to release the saw. Work calmly and methodically.

Chainsaw safety features

There are a number of safety aspects to consider when operating a chainsaw. Here is an overview of the safety features on Jonsered chainsaws.
1. Chain brake

The greatest hazard when working with a chainsaw is if the saw kicks back. Kickback can happen if something contacts the upper quadrant of the tip of the bar, or if you try to cut with that same quadrant (the “kickback sector”). The bar tip will then try to climb upwards, and the saw will be thrown backwards by the force of the rotating chain.

You should always make sure the bar tip does not contact anything, and never try to cut with the kickback sector of the bar.

This is why the chain brake is an important safety feature of the chainsaw. If activated, it can stop the chain in a fraction of a second in the case of a kickback. The chain brake can be triggered in two ways on all Jonsered saws: either by the motion of the saw during kickback, or if the wrist of your left hand strikes the kickback guard.

2. Chain catcher

If the saw chain is not maintained properly it may jump off or break. The chain catcher is designed to protect the operator by stopping the chain from flying backwards.

3. Right hand guard

Designed to protect your fingers if the chain jumps off or breaks.

4. Throttle lock

Prevents accidental throttle operation. As an additional safety feature you must activate the throttle lock to operate the throttle.

5. Stop button

Conveniently positioned so you can stop the engine quickly.

Clearing technique for plain grass

Our expert advice on how to clear plain grass, including movements and operating tips that make your work easier and more efficient.

Effective clearing of large areas of grass and long working hours call for powerful machines fitted with a trimmer head. The trimmer line’s cutting area is very large, but it is also very demanding on power, as the line causes a braking-while-cutting effect.

The engine as well as the cutting equipment work under extreme strain. Thanks to the torque increase, due to the gear ratio in the angle gear, even the smaller Jonsered brushcutters have a higher capacity than normal for their class. In parks, where grass clearing is often a question of removing weeds and trimming areas where lawn mowers cannot reach, this gives an extra power margin.

Working technique

You can work with either single or double-sided sweeping movements. Towards the end of the movement release the throttle and accelerate before starting the next movement. The reason why you should not operate the tool constantly at maximum speed is because clearing using a trimmer head is extremely demanding work for the machine. The engine must provide maximum power at the same time as the trimmer line causes a braking effect.

Clearing on slopes

The general rule when planning clearing work on slopes is that you always move along the slope, not up or down. Start at the bottom and let the cut material fall downwards, thereby avoiding using the machine in grass that has already been cut.

Chainsaws and personal safety

Wearing the right clothes and safety equipment when working with a chainsaw is extremely important. Here is an easy-to-follow guide to prevent injury.

When operating a chainsaw, you should never work in jeans or everyday shoes, even if you just cutting a little wood outside the front door. Protective clothes and equipment must always be used.

6 tips to dress safely

1. Protective trousers are important. Jonsered’s logging pants have built-in saw protection, with long fibres designed to jam the chain in an instant if it penetrates the outer fabric.

2. An approved helmet with hearing protectors and visor is also very important. These protect your hearing, eyes, face and head.

3. Our protective boots have steel toecaps, saw protection over the instep and a rugged tread pattern. They protect your feet and give you a safe footing.

4. Work gloves protect your hands from small cuts and grazes. Especially important when you sharpen or replace the chain.

5. A first aid kit should always be kept handy. Keep it in your shirt pocket or logger’s belt if you have one.

6. A long sleeved shirt or jacket is essential to protect your arms from sharp branches and flying chips.

You will find everything you need to work safely, and in comfort, at your local Jonsered dealer and in the Jonsered catalogue.

Clearing technique for coarse brush and bushes

Our expert advice on how to clear coarse brush and bushes, including movements and operating tips that make your work easier and more efficient.

The larger Jonsered machines are used with the heavier three-tooth grass and brush blade, which slices effortlessly through stems. If the stems are too thick, then fit a clearing blade, which will cut through the stem. “A rule of thumb”: When the stem is as thick as a thumb, use the clearing blade.

The smaller lightweight Jonsered machines are equipped with the four-tooth grass and brush blade, which works smoother and gives less kick. Alternatively fit a special clearing blade, Opti 26T, which has been specially designed for these machines. If you have a loop handle this should be changed to a “J” handle.

Sweeping movements

In dense vegetation it is preferable to work with a single-sided sweeping movement from right to left – or the reverse – and guide the cut material to the side. The density of the vegetation determines the width of the clearing arc.

In sparse vegetation you work with sweeping movements in both directions. Let the blade do the work using gentle sweeping movements releasing the throttle at the end of the movement. Before starting the next sweep, accelerate to bring the blade up to speed. Operating the blade at high speed gives it the required momentum, while releasing the throttle gives the engine a breathing space

How to use a brushcutter

There are a number of safety aspects to consider when using a brushcutter. Here is an overview of how to dress in order not to get injured, and how to operate the machine efficiently.


Preparations

Always wear a visor, safety glasses and hearing protection when clearing, or a safety helmet with visor and hearing protection if the stand reaches head height. Shoes, protective footwear or strong boots should always be worn.

In dense stands you should wear heavy-duty clothing. When clearing brush and grass, heavy-duty trousers and a shirt or jacket will generally be sufficient.

The harness and anti-vibration system

The design and individual adjustment options of the harness play a crucial role. The harness distributes the machine’s weight so that the body is not put under unnecessary strain. Therefore the harness should not hang loosely, but sit tight against the body. The machine’s suspension point should also be adjusted so that you obtain the correct working angle to the ground.

There are also several other fixing points on the machine, partly so the cutting equipment works parallel to the ground and partly so the machine is correctly balanced.

Most brushcutters are equipped with vibration damping between the engine and shaft. However, as soon as the cutting equipment starts to bite, other vibrations and types of impact occur. To overcome this, Jonsered has developed a unique anti-vibration system. The whole of the upper section with the handle and the section that rests against the body is isolated from the engine and shaft. Jonsered also has a full anti-vibration system on machines fitted with loop handles.

Starting point

The ideal starting point when using a brushcutter is this: A straight back, the hands extended comfortably in front of you and the cutting equipment directly in front of the body.

As Jonsered brushcutters have an angle between the double handle and the shaft, offset 7 degrees to the left, a left-hand sweep is not obstructed by the body and handle colliding. It is this, which allows you to effectively sweep in both directions, without excessive twisting of the back.

Each type of vegetation requires its own clearing technique. On this website you will find easy-to-follow how-to articles on clearing thick grass, plain grass, and coarse brush and bushes.
