Chain brake and front hand guard

Your chain saw is equipped with a chain brake that is designed to stop the chain if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.

Take care when using your saw and make sure the

• Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw ﬁrmly and not let go.

• The way the chain brake is activ ated, either manually or automatically b depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes.

• In the felling position the left hand is in a position that es manual activation of the chain brake

mak impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action.

Will my hand always activate the chain brake during a kickback?

No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force ma y not be enough to trigger the chain brake. You should also maintain a ﬁrm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you.

There are also certain positions in which your hand cannot reach the front hand guard to activ brake; for example, when the saw chain is held in felling position.

Will my inertia activated chain brake always activate during kickback in the event of a kickback?

No. First y our brak e m ust be in w orking order . Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do bef ore you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance.

ate the chain

Will my chain brake always protect me from injury in the event of a kickback?

No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake ma y be activated b ut if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you.

Only you and proper working technique can eliminate kickback and its danger.

Throttle lockout

The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you g rasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting.

Chain catcher

The chain catcher is designed to catch the chain if it snaps or jumps off. Replace it if necessary with an aluminium chain catcher (is available as spare part). This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions).

GENERAL SAFETY PRECAUTIONS

Right hand guard

Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.

The machine transfer of vibration between the engine unit/cutting equipment and the machine chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.

Cutting hardwoods (most broadleaf trees) creates more vibr with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.

Stop switch

Use the stop switch to switch off the engine.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minim um and to direct exhaust fumes away from the user.

WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a ﬁre. Never start the machine indoors or near combustible material!

In areas with a hot, dry climate there is a high risk of ﬁres. These areas are sometimes subject to go requiring among other things the mufﬂer must be equipped with an approved type of spark arrestor screen.

CAUTION! The mufﬂer gets very hot during and after use. This also applies during idling. Be aware of the ﬁre hazard, especially when working near ﬂammable substances and/or vapours.

vernment rules

WARNING! Overexposure to vibration can lead to circulatory damage or nerve

damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. These symptoms may be increased in cold temperatures.

Cutting equipment

This section describes how to choose and maintain your cutting equipment in order to:

• Reduce the risk of kickback.

• Reduce the risk of the saw chain breaking or jumping

• Obtain optimal cutting performance.

WARNING! Never use a saw without a mufﬂer, or with a damaged mufﬂer. A damaged mufﬂer may substantially increase the noise level and the ﬁre hazard. Keep ﬁre ﬁghting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen.

Sharpening your chain and adjusting depth gauge setting

General information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings.

• A sharp chain eats its way through the wood and produces long, thic

k chips or shavings.

When you sharpen a cutting tooth there are four important f

actors to remember.

1 Filing angle

2 Cutting angle

3 File position

4 Round ﬁle diameter

It is very difﬁcult to sharpen a chain correctly without the right equipment. We recommend that you use our ﬁle gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.

data for information on the size of ﬁle and gauge that are recommended for the chain ﬁtted to your chain saw.

• Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difﬁcult to sharpen correctly.

Adjustment of depth gauge setting

• The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.

• You will need a ﬂat ﬁle and a depth gauge tool. We recommend that y acheive the correct depth gauge setting and bevel f or the depth gauge.

• Always ﬁle cutting teeth from the inside face. Reduce the pressure on the retur one side ﬁrst, then turn the chain saw and ﬁle the teeth on the other side.

• File all the teeth to the same length. When the length of the cutting teeth is reduced to 5/32 inch (4 mm) the chain is w

General advice on adjusting depth gauge setting

• When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be ﬁled down to achieve the recommended depth gauge setting.

Tensioning the chain

WARNING! A slack chain ma y jump off the bar and cause serious or even fatal injury.

The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.

Check the chain tension every time you refuel. NOTE! A
