SAFETY INSTRUCTIONS
1 Chain brake and front hand guard
YOUR chain saw is equipped with a chain brake that is designed 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 freeswinging pendulum). On
most of our models the
front hand guard acts as a
counterweight in case of
kickback.
A
B
3a Starting
The chain brake should be
activated when starting.
b 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.
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).
2 The front hand guard is
notdesigned 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.
C
D
B
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.
English – 5
SAFETY INSTRUCTIONS
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 will
be activated manually by
the movement of your left
hand.
2 Throttle lock
The throttle lock is designed
to prevent accidental operation of the throttle control.
When you press the lock (A)
(i.e. when you grasp the
handle) it releases the throttle
trigger (B).
When you release the handle
the throttle trigger and the
throttle lock both move back
to their original positions. This
movement is controlled by two
independent return springs.
This arrangement means that
the throttle control is
automatically locked at the
idle setting when you release
the handle.
3 Chain catcher
The chain catcher is designed
to catch the chain if it snaps or
jumps off. This should not
happen if the chain is properly
tensioned (see section on
”Assembly”
chain are properly serviced
and maintained.
(See section on
workinginstructions”
) and if the bar and
”General
).
A
B
7 During felling your left
hand grasps the front
handle in such a way that
it cannot activate the front
hand guard. In this
position the chain brake
can only be activated by
the inertia action of the
counterweight.
The inertia activated
chain brake increases
your safety but there are
certain factors to
remember (see point 6
above).
4 Right hand guard
Apart from protecting your
hand if the chain jumps or
snaps, the right hand guard
stops branches and twigs
from interfering with your grip
on the rear handle.
6 – English
SAFETY INSTRUCTIONS
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 vibration
level.
6 Stop switch
Use the stop switch to switch
off the engine.
7 Muffler
The muffler is designed to keep noise levels to a minimum and
to direct exhaust fumes away from the user.
The vibration damping system
reduces the vibrations
transmitted from the engine
and chain to the handles of
the chain saw. The body of
the saw, including the cutting
equipment, is insulated from
the handles by vibration
damping units.
Overexposure to vibration can lead to
circulatory damage or nerve damage in people
who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
These symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin colour or condition.
These symptoms normally appear in the
fingers, hands or wrists.
The exhaust fumes from the engine are very
hot and may contain sparks which can start a
fire. Never start the saw indoors or near
combustible material!
In areas with a hot, dry
climate there is a high risk of
forest fires. These areas are
sometimes controlled by
legislation and requirements
that among other things the
muffler must be equipped with
an approved type of spark
arrestor mesh.
For mufflers it is very
important that you follow the
instructions on checking,
maintaining and servicing your
saw (see the section on
”Inspecting, maintaining and
servicing chain saw safety
equipment”
).
The muffler gets very hot in use and remains
so for a short time afterwards. DO NOT
TOUCH THE MUFFLER IF IT IS HOT!
WARNING!
The catalytic converter muffler gets very hot
during and after use. This also applies during
idling. Be aware of the fire hazard, especially
when handling the saw near flammable
substances or vapours.

SAFETY INSTRUCTIONS
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.
When you buy any of our products we
guarantee the availability of professional
repairs and service. If the retailer who sells
your saw is not a SERVICING DEALER, ask
him for the address of your nearest SERVICE
AGENT.
1 Chain brake and front hand guard
1 Checking brake band wear
Brush off any sawdust,
resin and dirt from the
chain brake and clutch
drum. Dirt and wear can
impair operation of the
brake.
3 Checking the inertia brake release
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.
Regularly check that the
brake band is at least 0.6
mm thick at its thinnest
point.
2 Checking the front hand guard
A Make sure the
FRONT HAND GUARD
is not damaged and
that there are no visible
defects such as cracks.
B Move the front hand
guard forwards and
back to make sure it
runs freely and that it is
securely anchored to
the clutch cover.
4 Checking the brake trigger
Start the chain saw and
place it on firm ground.
Make sure the chain does
not touch the ground or
any other object.
Grasp the saw firmly,
wrapping your fingers and
thumbs around the
handles.
Apply full throttle and
activate the chain brake
by tilting your wrist
forward onto the front
hand guard. Do not let go
of the front handle.
The chain should stop
immediately.

English – 9
SAFETY INSTRUCTIONS
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.
CUTTING EQUIPMENT
This section describes how to choose and maintain your cutting
equipment in order to:
• Reduce the risk of kickback.
• Reduce the risk of the chain breaking or jumping.
• Obtain maximum cutting performance.
• Extend the life of cutting equipment.
The 5 basic rules
1 Only use cutting
equipment
recommended by us!
See the
section.
2 Keep the chain cutting
teeth properly
sharpened! Follow our
instructions and use the
recommended file
gauge. A damaged or
badly sharpened chain
increases the risk of
accidents.
”Technical data”
NEVER USE A CHAIN SAW WITH FAULTY
SAFETY EQUIPMENT. CARRY OUT THE
CHECKS AND MAINTENANCE MEASURES
DESCRIBED IN THIS SECTION. IF YOUR
CHAIN SAW FAILS ANY OF THESE CHECKS
CONTACT YOUR SERVICE AGENT TO GET IT
REPAIRED.
3 Maintain the correct
raker clearance! Follow
our instructions and
use the recommended
raker gauge. Too large a
clearance increases the
risk of kickback.
4 Keep the chain properly
tesioned! If the chain is
slack it is more likely to
jump off and lead to
increased wear on the
bar, chain and drive
sprocket.
5 Keep cutting equipment
well lubricated and
properly maintained!
A poorly lubricated chain
is more likely to break and
lead to increased wear on
the bar, chain and drive
sprocket.
