Safety features

1. Always check that the safety features are in working
order before starting work. Do not use the chain
saw if the safety features are not working properly.
— Chain brake:
The chain saw is fitted with a chain brake which
brings the saw chain to a standstill within a fraction
of a second. It is activated when the hand guard
is pushed forwards. The saw chain then stops
within 0.15 s, and the power supply to the motor is
interrupted.
1. Chain brake applied 2. Chain brake released
— Run-down brake:
The chain saw is equipped with an run down
brake which brings the saw chain to an immediate
stop when the ON/OFF switch is released. This
prevents the saw chain from running on when
switched off, and thus presenting a hazard.
— The front and rear hand guards protect the user
against injury from pieces of wood which may be
thrown backwards, or a broken saw chain.
— The trigger lockout prevents the chain saw from
being switched on accidentally.
The chain catcher protects the user against injury
—
should the chain jump or break.

Transport and storage

When the chain saw is not in use or is
being transported, withdraw the mains plug
and fit the guide bar cover supplied with the
saw. Never carry or transport the saw with
the saw chain running.

1. Carry the chain saw by the front handle only, with
the bar pointing backwards.
2. Keep the chain saw in a secure, dry and locked
room out of the reach of children. Do not store the
chain saw outdoors.
MAINTENANCE
1. Withdraw the plug from the socket before carrying
out any adjustments or maintenance.
2. Check the power cable regularly for damage to the
insulation.
3. Clean the chain saw regularly.
4. Have any damage to the plastic housing repaired
properly and immediately.
5. Do not use the saw if the switch trigger is not
working properly. Have it properly repaired.
