chain, see page 14.
IMPORTANT! If the carburettor mixture is too lean it greatly
increases the risk of engine failure.
Poor maintenance of the air filter will cause carbon build-up on
the spark plug and lead to difficult...

CHAIN SAW SAFETY EQUIPMENT
This section explains the various safety features of the saw,
how they work, and basic inspection and maintenance you
should carry out to ensure safe operation. (See the 
ÓWhat is

saw).
NEVER USE A CHAIN SAW THAT HAS
FAULTY SAFETY EQUIPMENT! Carry out the
inspection, maintenance and service routines
listed in this section.

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...

6 Ð English
6 The way the chain brake is triggered, either manually or
automatically, depends on the force of the kickback and the
position of the chain saw in relation to the object that the
kickback zone of the bar strikes.
If you get a violent
kickback while the
kickback zone of the bar
is farthest away from you
the chain brake will be
activated by the
movement of the
counterweight (INERTIA
ACTIVATED).
If the kickback is less
violent or the kickback
zone of the bar is closer
to you the chain brake...

5 Vibration damping system
Your chain saw is equipped
with a vibration damping
system that is designed to
minimise vibrations and make
operation easier.
When you use a chain saw
vibrations are generated by
the uneven contact between
the chain and the wood you
are cutting.
Cutting hardwoods (most
broadleaf trees) creates more
vibration than cutting
softwoods (most conifers).
Cutting with a chain that is
blunt or faulty (wrong type or
badly sharpened, see section
D) will increase the...

3 Checking the automatic brake
Hold the chain saw over a
stump or other firm object.
Let go of the front handle
so that the bar falls onto
the stump.
When the bar hits the
stump the brake should
be applied.
Inspecting, maintaining and servicing
chain saw safety equipment
SPECIAL TRAINING IS REQUIRED to service
and repair chain saws. This is especially true
of chain saw safety equipment. If your chain
saw fails any of the checks described below
take it to your SERVICE AGENT.

7 Muffler
Never use a chain saw
that has a faulty muffler.
Regularly check that the
muffler is securely
attached to the chain saw.
If the muffler on your saw
is fitted with a spark
arrestor mesh this must
be cleaned regularly. A
blocked mesh will cause
the engine to overheat
and may lead to serious
damage.
Never use a muffler if
the spark arrestor mesh
is missing or defective.
NEVER USE A CHAIN SAW WITH FAULTY
SAFETY EQUIPMENT. CARRY OUT THE
CHECKS AND MAINTENANCE MEASURES
