Chain brake
The saw is equipped with a chain brake. The brake is designed to
stop the chain immediately in the event of a kick-back. The brake
activates when the hand guard is pushed forward (1).
If the brake is aiready activated, it is disengaged by pulling the
front hand guard back towards the front handle (2).
When working with the saw, the chain brake must be disengaged.
Use the chain brake as a ’’parking brake”, if you move the saw
with the engine running.
Inertia activated chain brake
The inertia activated chain brake is activated when the front hand
guard is pushed forward, either manuaily or by a weight in the
hand guard.
The advantage of the inertia brake is that the brake is activated
after kick-back, even if the user’s left hand does not contact the
hand guard, i.e., also when the saw is in the feliing position.
Control and maintenance of the chain brake
Braking function control:
The chain brake must be checked several times daily. Place the
saw on firm ground. Hold the handles with both hands and apply
full throttle. Activate the chain brake by turning your left wrist
against the hand guard, without releasing your grip around the
front handle. The chain should stop immediately (illustr.).
Inertia activating function control
The chain brake must be checked several times daiiy. Hold the
chain saw approx. 35 cm (14") above a trunk or other firm object
(illustr.).
CAUTION! The engine must be shut off.
Release your grip around the front handle and let the saw by its
own weight rotate around the rear handle. When the tip of the bar
hits the trunk, the brake should activate.
Maintenance:
/j\ WARNING! Dirt and wear affect the function of the brake.
’ Follow all maintenance instructions, carefully. If anything is
incorrect with your chain brake contact your servicing dealer.
With the engine shut off, the hand guard can be moved back and
forth, to ensure that the mechanism works freely and also that the
brake activates. If necessary, clean the brake from resin and
chips. Lubricate the mechanism and bearing surfaces with oil.
Check that the brake band is at least 0.65 mm (.026 in) thick, at
the most worn part.
