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
x
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.
x
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
x
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
x
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
x
the mains supply.
Pull the front guard (5) back into the "set"
x
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
x
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
x
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
x
chainbrake.
Notes:
It will not be possible to switch the tool on if
x
the front guard is not in the "set" position.
Avoid re-starting the tool until you hear the
x
motor come to a complete rest.
If the chain does not come to rest immediately
x
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.
x
Push the lock-off button (2) forward and then
push the on/off switch (1) to start.
When the motor starts, remove your thumb
x
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.
