pushback!
Lying logs must not touch the ground at
the point where the cut is made –
otherwise the chain will be damaged.
Ripping

spiked bumper – risk of pull-in – position
the guidebar at as shallow an angle as

Vibrations
This power tool is minimizes the
vibrations transmitted to the operator's
hands.
However, the operator should seek
medical advice in the event of suspected
circulatory problems in the hands (e.g.
tingling sensation in the fingers).
Maintenance and repairs
Before all maintenance and repair work,
set the hand guard to ƒ and remove the
battery from the machine. This prevents
inadvertent starting of the motor.
The machine must be serviced regularly.
Do not attempt any maintenance or
repair work not described in the
Instruction Manual. All other work should
be carried out by a servicing dealer.
