back so that you will not be struck when the tension
in the wood fibers is released. DO NOT stand on the
section of the tree limb which is being cut off.
● MAINTAIN THE CHAIN SAW WITH CARE. Keep the
cord clear of the chain at all times. Never carry the saw
by the cord or pull on the cord to disconnect it from the
socket. Keep the handles dry, clean and free from oil.
When storing the saw, use a scabbard or carrying case.
● PROTECT YOURSELF. Always wear goggles and
protective gloves when working with the chain saw or
while loading or adjusting the saw blade. To prevent
damage to your hearing, wear ear protectors; helmets
with a visor are particularly advantageous. Tight fitting
clothing and safety boots should also be worn to prevent
injury.Wear a dust mask if operation is dusty.
● CHAIN TENSION. Make sure that the chain tension
is correct, as specified in these instructions. Incorrect
tension may cause the chain to disengage from the
guide bar, which is extremely dangerous.
● THE CHAIN SAW MUST NOT BE OPERATED BY
ANYONE YOUNGER THAN 18 YAERS OF AGE. Always
pass on the operating instructions together with the chain
saw when lending it to someone else.
● CARRYING THE SAW. Before picking up the saw,
ensure that it has come to a complete stop and that your
finger is off the switch. Carry the saw by the front handle,
with the guide bar and the saw chain to the rear.
● GRIP SAW FIRMLY. Hold the saw securely with both
hands while the motor is running. Use a firm grip with
your thumbs and fingers encircling the chain saw
handles.
● THE SAW MUST NOT BE TOUCHING ANYTHING
WHEN IT STARTS UP.
● BEFORE MAKING A CUT, ALWAYS PLACE THE CLAW
STOP NEXT TO THE WOOD BEING CUT.
● ALWAYS HAVE FIRM FOOTING. NEVER use the chain
saw when standing on a ladder, in a tree or in any other
unstable places. DO NOT saw with one hand.
● USE A STRONG SUPPORT WHEN SAWING
CONVERTED TIMBER AND THIN BRANCHES. DO
NOT stack the timber and do not have it held by a
second person or with your foot.
● LOGS MUST BE SECURED IN POSITION.
● ON SLOPING GROUND, ALWAYS WORK FACING
UPWARDS.
● PULL THE SAW OUT OF WOOD ONLY WHEN THE
CHAIN SAW IS RUNNING.
● IF YOU ARE CARRYING OUT SEVERAL CUTS,
SWITCH OFF THE CHAINSAW IN-BETWEEN.
● SWITCH THE CHAIN SAW OFF BEFORE RELEASING
THE CHAIN BRAKE.
● PLUNGE CUTS AND HORIZONTAL CUTS MAY ONLY
BE CARRIED OUT BY PROFESSIONALS. There is a
high risk of kickback.
● HOW TO PREVENT KICKBACK. Kickback is the recoil
motion of the guide bar that occurs when the saw chain
at the tip (especially the top quarter) of the guide bar
contacts wood or any other solid object. In this case,
the saw will be uncontrolled and will be hurled towards
the operator at full power. Kickback can lead to loss of
control of the chain saw which is extremely dangerous.
● To avoid kickback:
a) Hold the chain saw firmly with both hands.
b) Do not over reach.
c) Do not let the nose of the guide bar contact a log,
branch, the ground, or any other obstruction.
d) Do not cut above shoulder level.
e) Make sure the chain is always properly sharpened.
Follow the details regarding sharpening and
maintenance contained in these instructions for a
better and safer performance. Follow the instructions
for lubricating and changing the guide bar.
f) Use devices such as a low kickback chain and chain
brake.
g) Never start cutting or cut with the tip of the guide
bar. Be careful when continuing cuts you are already
working on.
h) Always start cuts with the chain saw already running.
i) Never cut through more than one branch at a time.
When lopping off branches, be careful not to touch
any other branches.
j) When cross-cutting, pay attention to trunks standing
very close to each other. If possible use a saw-horse.
● IF THE CHAIN GETS STUCK WHEN SAWING WITH
THE UPPER SIDE OF THE GUIDE BAR IT MAY BE
THRUST TOWARDS THE OPERATOR. For this reason
you should saw wherever possible with the bottom side
of the guide bar, as the chain saw will then be thrust
away from the body towards the wood.
● PAY EXTRA ATTENTION WHEN CUTTING
SPLINTERED WOOD. Sawed off pieces of wood may be
catapulted in any direction causing a high risk of injury.
● WHEN LOPPING OFF BRANCHES, THE CHAIN SAW
SHOULD BE SUPPORTED WHEREVER POSSIBLE
AGAINST THE TRUNK. Branch lopping should be
carried out by trained personnel as there is a high risk
of injury.
● NEVER STAND ON THE TRUNK WHEN LOPPING OFF
BRANCHES.
● PAY SPECIAL ATTENTION TO BRANCHES UNDER
TENSION. DO NOT cut through freely suspended
branches from underneath.
● THIS CHAIN SAW SHOULD NOT BE USED FOR
FOREST WORK, ie. for felling and lopping off branches
in a forest. Because of the cable connection the saw
operator does not have the necessary mobility and his
safety is not guaranteed.
● ALWAYS STAND TO THE SIDE OF THE TREE BEING
FELLED.
● WHEN THE TREE IS BEING FELLED, WATCH OUT
FOR FALLING BRANCHES WHEN YOU STEP BACK.
● WATCH OUT FOR TRUNKS ROLLING TOWARDS
YOU.
