Chain Brake; Checking The Clutch - Bavaria BPC 1950 Mode D'emploi

2. Fill the oil tank (B) with chain oil (Fig. 4).
Once you have fi lled the chain and oil tank, tigh-
ten the tank cover securely by hand. Do not use
any tools to do so.
6. Operation
Before you use the saw, check it for damage.
If you discover any damage, do not use it. The
chainsaw may be started only when the chain
brake is engaged. The chain brake is engaged
when the brake lever (6) is pushed forward.
Explanation of how it works: refer to Che-
cking the chain brake - Static check.

6.1 Chain brake

The chainsaw is fi tted with a chain brake which
reduces the risk of injury caused by the danger of
kickback. The brake is engaged when pressure is
applied to the hand guard (6), e.g. when the hand
of the person operating the chainsaw strikes the
hand guard (6) if kickback occurs. When the bra-
ke is engaged, the chain (3) stops abruptly.
Warning: The chain brake is intended to reduce
the risk of injury due to kickback; however, it is un-
able to provide adequate protection if the saw is
used carelessly. You must check the operation of
the chain brake on a regular basis. Test the chain
brake before the fi rst cut, after several cuts, after
maintenance is done on the chainsaw and if the
chainsaw has been subjected to strong impact or
if it has been dropped.
6.1.1 Checking the chain brake (Fig. 5A/5B/6)
Static check (engine switched off )
Chain brake disengaged (chain (3) is free to
move)
1. Pull the front hand guard (6) towards the front
handle (7). The front hand guard (6) must
make an audible click when it snaps into
place. (Fig. 5A)
2. It must be possible to move the chain (3) on
the guide rail (2).
Chain brake engaged (chain (3) is blocked)
1. Push the front hand guard (6) towards the
guide rail (2). The front hand guard (6) must
make an audible click when it snaps into
place. (Fig. 5B)

2. It must not be possible to move the chain (3)
on the guide rail (2).
Note: The front hand guard (6) must snap into
place in both positions. If you feel strong resis-
tance or if the front hand guard (6) does not snap
into place, do not use the chainsaw. Take your
chainsaw to an authorized service center for
repair.
Dynamic check (engine is started)
1. Place the saw on a fi rm and level surface.
2. Hold the front handle (7) with your left hand.
3. Start the chain saw by following the starting
instructions. (refer to 6.2 and 6.3)
4. Disengage the chain brake (pull the front
hand guard (6) towards the front handle (7)).
(Fig. 5A)
5. Grasp the rear handle (8) with your right
hand.
6. After a brief warmup period, run the engine
at full speed. With the back of your left hand,
push the front hand guard (6) towards the gui-
de rail (2). This will engage the chain brake.
(Fig. 6)
Danger: Engage the chain brake slowly and ca-
refully. Hold the saw fi rmly with both hands, and
make sure you have a good grip. The saw must
not touch any objects.
7. The chain (3) must stop abruptly. Immediately
release the throttle lever (11) when the chain
(3) has come to a stop.
Danger: If the chain (3) does not stop, shut off
the engine and take the saw to an authorized ser-
vice center for repair.

6.1.2 Checking the clutch

Carry out a functional check on the clutch on a re-
gular basis. Test the clutch before the fi rst cut, af-
ter several cuts, after maintenance is done on the
chainsaw and if the chainsaw has been subjected
to strong impact or if it has been dropped.
1. Start the chain saw by following the starting
instructions. (refer to 6.2 and 6.3)
2. Briefl y actuate the throttle lever and release
it to ensure that the throttle valve has been
released and the engine is idling.
3. The chain (3) must stop when the engine is
idling. The clutch has been designed so that
when the idling speed is increased by a factor
of 1.25 no chain movement can be detected.
