WARNING
The brake lever should snap into both positions. If
strong resistance is felt, or the lever does not move
into either position, do not use your saw. Take it im-
mediately to a professional Service Centre for repair.

Fuel and oil – Recommended fuels
Use only a mixture of unleaded petrol and special
2-stroke engine oil. Mix the fuel mixture as indicated
in the fuel mixing table.
m
CAUTION
Do not use a fuel mixture which has been stored for
longer than 90 days.
m
CAUTION
Never use 2-stroke oil with a recommended mixing
ratio of 1:40. The manufacturer’s warranty will be
voided in case of engine damage due to inadequate
lubrication.
m
CAUTION
Only use containers designed and approved for the
purpose to transport and store fuel. Pour the cor-
rect quantities of petrol and 2-stroke oil into the mix-
ing bottle provided (see scale printed on the bottle).
Then shake the bottle well.
Recommended fuels
Some conventional petrols are being blended with
oxygenates such as alcohol or an ether compound
to meet clean air standards. Your engine is designed
to operate satisfactorily on any petrol intended for
automotive use including oxygenated petrols.
It is recommended to use unleaded petrol as fuel.
Lubrication of chain and chain bar
Whenever you refill the fuel tank with petrol you must
also top up the level of chain oil in the chain oil tank.
It is recommended to use standard chain oil.

CAUTION
Never start or operate the saw unless the bar, chain
and chain brake lever / front hand guard are proper-
ly installed. In addition, always start with the chain
brake active. Proceed as follows for this:
m
WARNING
Wear high-strength gloves at all times when handling
or adjusting the saw chain.
m
If the chain is hard to turn around the chain bar or
jammed, it is too tightly tensioned. Make the following
small adjustments:
1. Undo the bar fastening wheel (Fig. 9/pos. 18) by
1/2 of a turn COUNTERCLOCKWISE. Then slack-
en the chain tension by slowly turning the chain
tensioning wheel (Fig. 9/pos. 3) IN A COUN-
TER-CLOCKWISE DIRECTION and then pull the
chain back and forth on the bar (Fig. 30). Contin-
ue until the chain can be moved smoothly but is
still closely seated (Fig. 4/pos. X2). Increase the
tension by turning the chain tensioning wheel IN
A CLOCKWISE DIRECTION.
2. When the saw chain is correctly tensioned, hold
the tip of the bar upwards and completely tighten
the bar fastening wheel (Fig. 9/pos. 18).
m
A new saw chain stretches, requiring adjustment
after as few as 5 cuts. This is normal with a new
chain, and the interval between future adjustments
will lengthen quickly.
m
If the saw chain is TOO LOOSE or TOO TAUT, the
drive wheel, chain bar, chain and crank shaft bearing
will suffer premature wear. Fig. 4/pos. X2 shows the
correct tension (when cold) and Fig. 4/pos. X3 shows
the tension (when warm). Fig. 4/pos. X1 shows a
chain that is too loose.
3. Chain brake mechanical test
Your chainsaw is equipped with a chain brake that
reduces the possibility of injury due to kickback. The
brake is activated if pressure is applied against the
brake lever when, as in the event of kickback, the
operator’s hand strikes the lever. When the brake is
actuated, chain movement stops abruptly.
m
WARNING
The purpose of the chain brake is to reduce the pos-
sibility of injury due to kickback; however, it cannot
provide the intended measure of protection if the saw
is operated carelessly. Always test the chain brake
before using your saw and periodically while on the
job. (See below for details of how to perform a test
of the mechanical brake).
4. To test chain brake
• The chain brake is DISENGAGED (chain can move)
when the BRAKE LEVER (5) IS PULLED BACK
(Fig. 11/pos. 2) AND LOCKED shown in Fig. 11.
• The chain brake is Activated (the chain is locked)
when the brake lever (5) is pulled forward and
the mechanism (shown in Fig. 10) can be seen. It
should not be possible to move the chain (Fig. 30).
