Checking and adjusting the chain tension (fig. D)

Before use and after every 10 minutes of use,

you must check the chain tension.

◆ Lightly pull on the chain as shown. The tension

is correct when the chain snaps back after

being pulled 3 mm away from the guide bar.

There should be no “sag” between the guide

bar and chain on the underside.

Note: Do not over-tension the chain as this will

lead to excessive wear and will reduce the life of

the bar and chain.

Note: When the chain is new, check the tension

frequently (after disconnecting from the mains)

during the first 2 hours of use as a new chain

stretches slightly.

To increase the tension:

◆ Turn the screw (14) clockwise.

USE

Let the tool work at its own pace. Do not

overload.

Filling oil into the reservoir (fig. E)

◆ Remove the oil cap (3) and fill the reservoir with

the recommended chain oil. You can see the oil

level in the indicator slot (4). Refit the oil cap.

◆ Periodically switch off and check the oil in the

indicator; if it is less than a quarter full,

disconnect your chainsaw from the mains and

refill with the correct oil.

Auto-stop chainbrake (fig. F & G)

This tool is fitted with an auto-stop chainbrake which

will stop the chain within 150 ms each time you

release the rear trigger, or if kickback should occur.

This brake should be tested before every use.

How to set the chainbrake

◆ Make sure that the tool is disconnected from

the mains supply.

◆ Pull the front guard (5) back into the “set”

position .

The tool is now ready to use.

How the anti-kickback chainbrake works

In the event of kickback, your left hand comes in

contact with the front guard, pushing it backwards,

and stops the tool within 150 ms.

How the inertia activated chainbrake works

The chainbrake is activated when the front hand

guard is pushed forward, either manually, by the

back of the users hand or by its own weight. The

advantage of the inertia brake is that it is activated

by a severe kickback, eg. when the chain hits metal,

even if the users hand does not contact the front

guard, ie. when the saw is in the felling position.

How to test the anti-kickback chainbrake

◆ Grip the tool firmly in both hands on a firm

surface - make sure the chain is clear of the

ground and switch on (see “How to switch your

chainsaw on”).

◆ Rotate your left hand forward around the front

handle so that the back of your hand comes in

contact with the front guard and pushes it

backwards (fig. G). The chain should stop

within a few fractions of a second.

To reset after the operation of the chainbrake

◆ Follow the instructions for setting the

chainbrake.

Notes:

◆ It will not be possible to switch the tool on if

the front guard is not in the “set” position.

◆ Avoid re-starting the tool until you hear the

motor come to a complete rest.

◆ If the chain does not come to rest immediately

then this indicates that it needs tensioning (see

“Fitting the guide bar and chain”).

How to switch the tool on (fig. A)

◆ Grip your chainsaw firmly with both hands.

Push the lock-off button (2) forward and then

push the on/off switch (1) to start.

◆ When the motor starts, remove your thumb

from the lock button and grip the handle firmly.

Do not force the tool - allow it to do the work.

It will do a better and safer job at the speed for

which it is designed. Excessive force will stretch

the chain.
