1 Chain brake and front hand guard

YOUR chain saw is equipped with a chain brake that is desig-
ned to stop the chain immediately if you get a kickback.
The chain brake reduces the risk of accidents, but only You can
prevent them.

Take care when using your
saw and make sure the
kickback zone of the bar
never touches any object.

1

The chain brake (A) can
either be activated
manually (by your left
hand) or automatically by
the inertia release
mechanism (a free-
swinging pendulum). On
most of our models the
front hand guard acts as a
counterweight in case of
kickback.

The brake is applied
when the front hand
guard (B) is pushed
forwards.

This movement activates
a spring-loaded
mechanism that tightens
the Brake Band (C)
around the engine drive
system (D) (Clutch Drum).

SAFETY INSTRUCTIONS

2

The front hand guard is
not designed solely to
activate the chain brake.
Another important safety
feature is that it prevents
the chain from hitting your
left hand if you lose your
grip on the front handle.

3

You can also use the
chain brake as a
temporary brake when you
change position or if you
put the saw down for a
short time. You should
also apply the chain brake
manually if there is a risk
of the chain accidentally
hitting anyone or anything
close by.

4

To release the chain brake
pull the front hand guard
backwards, towards the
front handle.

5

As mentioned in section A,
kickback can be very
sudden and violent.
Most kickbacks are
minor and do not always
activate the chain brake.
If this happens you
should hold the chain
saw firmly and not let
go.
