CHECKING THE BRAKE FUNCTION (continued)
• The chain should stop immediately.
• Release the throttle trigger.
PRE CUTTING TEST
• Familiarize yourself with your chain saw before you start cutting.
• For this purpose it may be wise to practice by cutting some small
logs or limbs several times.
• Do not allow either people or animals 15m into the work area. Multiple operators - Keep a safe distance between two or
more operators when working together simultaneously. Fig 9.
CHAIN LUBRICANT
• Hold the chain just above a dry surface and open the throttle to half speed for 30
seconds A thin line of “thrown” oil should be seen on the dry surface. Fig 10.
RELEASE THE CHAIN BRAKE
• When front hand guard is fully pulled towards the operator, chain brake is released.
• If the chain does not stop immediately, bring the saw to your Bushranger dealer to repair.
WARNING
Most hazardous is the kickback motion of the guide bar such that, in an instant the tip of the bar touches a wood or the
like. Chain brake reduced the possibility of injury due to kickback. You must always check that chain brake works properly
before use.
NON-MANUAL CHAIN BRAKE
The non-manual chain brake stops the operation of the saw chain in such a manner that kickback action produced at
the end of the guide bar non-manually actuates the chain brake. To make sure that the non-manual chain brake operates
properly, proceed as follows:
a. Stop the engine of the chain saw.
b. Operate the front and rear handles with hands (grip them lightly), so that the guide bar may be placed at the height of
about 35cm as shown in the figure aside.
c. Softly detach the left hand from the front handle, and touch the end of the guide bar against the wood or the like placed
below so that the machine receives an impact. (*at this time the rear handle should be gripped lightly with right hand).
The impact is propagated to the brake lever, which actuates the chain brake.
NOTE:
• For practice, while cutting a small tree, push the front guard forward to engage the brake.
• At all times, confirm whether the brake works properly before each work.
• If the chain brake is clogged with wood chips, function of the brake deteriorates a little. Always keep the device clean.

NON-MANUAL CHAIN BRAKE
•Release throttle trigger and turn ignition switch down.
NOTE
When engine does not stop, pull choke control knob
all the way out to stop engine.
Check and repair ignition switch before starting the
engine again.
•Chain tension should be checked frequently during
work and corrected if necessary.
•Tension the chain as tight as possible, but so it can
still be pulled easily along the bar by hand.
WARNING ▲ DANGER
MAKE SURE THAT THE ENGINE IS SHUT OFF
WHEN CHECKING CHAIN TENSION.
1) Place the chain saw on the ground.
2) Hold the handle with both hands and accelerate the
engine to high speed by throttle trigger.
3) Operate the chain brake by turning your left wrist
against the front hand guard during your grip on the
front handle.
4) The chain stop immediately.
5) Release the throttle trigger.
•Familiarize yourself with your chain saw before you

RUNNING
• After engine starts, allow it to idle for a few
minutes.
• Squeeze throttle trigger gradually to
increase engine revolution.
• The chain starts moving when the engine
reaches 3,800 r/min approximately.
• Ensure proper acceleration and lubrication
of saw chain and guide bar.
• Do not run the engine at high speed
unnecessarily.
• Be sure that saw chain stops moving when
throttle trigger is released.
STOPPING THE ENGINE
• Release throttle trigger and turn ignition
switch down.
NOTE
• When engine does not stop, pull choke
control knob all the way out to stop engine.
• Check and repair ignition switch before
starting the engine again.
CHECKING CHAIN TENSION
• Chain tension should be checked
frequently during work and corrected if
necessary.
• Tension the chain as tight as possible, but
so it can still be pulled easily along the bar
