General
The user must only carry out the maintenance and
service work described in this Operator's Manual. More
extensive work must be carried out by an authorized
service workshop.
Checking, maintaining and
servicing chain saw safety
equipment
WARNING! Always unplug the chainsaw
!
from the power supply before any
assembly, maintenance and/or checking
is done on the machine.
Note! All service and repair work on the machine
demands special training. This is especially true of the
machine's safety equipment. If your machine fails any of
the checks described below we recommend that you
take it to your service workshop.
Chain brake and front hand guard
Checking the front hand guard
•
Make sure the front hand guard is not damaged and
that there are no visible defects such as cracks. (75)
•
Move the front hand guard forwards and back to make
sure it moves freely and that it is securely anchored to
the machine. (76)
Checking the inertia brake release
•
Place the chain saw, deactivated, above a stump or
other stable surface. Release the front handle and let
the chain saw fall by its own weight, rotating around
the rear handle towards the stump.
When the bar hits the stump the brake should be
activated. (77)
Checking the brake trigger
•
Activate the chain saw. Make sure the saw chain does
not touch the ground or any other object. See
instructions under the heading Starting and stopping.
•
Grasp the chain saw firmly, wrapping your fingers and
thumbs around the handles. (44)
•
Apply full power and activate the chain brake by tilting
your left wrist forward onto the front hand guard. Do
not let go of the front handle. The chain should stop
immediately. (78)
Power trigger lockout
•
Make sure that the power trigger is locked at the idle
setting when the power trigger lockout is released.
(79)
•
Press the power trigger lockout and make sure it
returns to its original position when released. (80)
24 – English
MAINTENANCE
•
Check that the power trigger and power trigger lockout
move freely and that the return springs work properly.
(81)
•
Activate the chain saw and apply full power. Release
the power trigger and check that the saw chain stops
and remains stationary.
Chain catcher
•
Check that the chain catcher is not damaged and is
firmly attached to the body of the chain saw. (82)
Cooling system
To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1
Air intake (under the power trigger).
2
A fan on the motor.
•
Clean the cooling system with a brush once a week,
more often in demanding conditions. A dirty or
blocked cooling system results in overheating which
causes damage to the machine.
