WARNING
Failure to switch from normal mode to anti-freeze mode
in temperatures of ≤5 °C will reduce the output power of
the engine or lead to engine failure.
Always remember to return the product to the normal
operating mode when there is no risk of ice forming
inside the carburettor. Failure to switch from anti-freeze
mode to normal mode at normal temperatures may
result in engine failure.
STOPPING THE ENGINE
Release the throttle trigger and let the engine return to idle.
To stop the engine, move the ignition switch to the stop
(0) position. Do not put the product on the ground when
the chain is still moving. For additional safety, set the chain
brake when the product is not in use.
In the event that the ignition switch will not stop the product,
pull the choke lever out to the fully extended position (Full
Choke) and engage the chain brake to stop the engine.
If the ignition switch will not stop the product when set to
the stop position, have the ignition switch repaired before
using the product again to prevent unsafe conditions or
serious injury.
NOTE: When you are fi nished using the product, always
relieve tank pressure by loosening, then retightening, the
chain lubricant and fuel caps. Allow the engine to cool down
before storing.
HOLDING THE PRODUCT
See page 343.
Always hold the product with your right hand at the rear
handle and your left hand at the front handle. Grip both
handles with the thumbs and fi ngers encircling the handles.
Ensure that your left hand is holding the front handle so that
your thumb is underneath.
CHECKING AND OPERATING CHAIN BRAKE
1. Engage the chain brake by rotating your left hand
around the front handle. Allow the back of your hand to
push the chain brake lever/hand guard toward the bar
while the chain is rotating rapidly. Be sure to maintain
both hands on the handles of the product at all times.
2. Reset the chain brake back into the Run position by
grasping the top of the chain brake lever/hand guard
and pulling toward the front handle until you hear a
click.
WARNING
If the chain brake does not stop the chain immediately,
or if the chain brake will not stay in the run position
without assistance, take the product to an authorised
service centre for repair prior to use.
WARNING
When the throttle trigger is released and the engine is
running at idle speed, the saw chain must not move. If
it does continue to move there is risk of severe injury
to the operator. Do not use the product, return it to an
authorised service centre for professional adjustment.
CHECKING THE CLUTCH
1. Disengage the chain brake by pulling the chain brake
lever/hand guard towards the front handle until a click
is heard.
2. Allow the engine to run idle. Ensure that the saw chain
is not rotating. If the saw chain rotates while running at
idle speed, the clutch may be damaged. Do not use the
product. Return it to an authorised service centre for
professional adjustment.
3. Depress the throttle trigger half-way and run the product
at mid speed. The saw chain should rotate smoothly if
the clutch is in good working condition.
RESTARTING AFTER EXTENDED PERIODS OF HEAVY
USE
After using the chain saw for extended periods of time,
please let the unit run in idle, with the chain brake engaged
for 3 to 5 minutes, allowing accumulated heat of the engine
to dissipate through the forced-air cooling system.
This helps prevent a potential heat soak and thus potential
high stress of certain engine components (i.e. ignition
system and carburettor).
After complete shut-off of the engine, you may experience
diffi culties restarting the chain saw due to this condition,
which is completely normal. Thus, please allow the unit to
cool down before restarting.
Causes and operator prevention of kickback:
Kickback may occur when the nose or tip of the guide bar
touches an object, or when the wood closes in and pinches
the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator.
Pinching the saw chain along the top of the guide bar may
push the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of
the saw which could result in serious personal injury. Do
not rely exclusively upon the safety devices built into your
saw. As a chainsaw user, you should take several steps to
keep your cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below:
■ Maintain a firm grip, with thumbs and fingers
encircling the chainsaw handles, with both hands
on the saw and position your body and arm to allow
you to resist kickback forces. Kickback forces can
be controlled by the operator, if proper precautions are
taken. Do not let go of the chainsaw.
■ Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact and
