2. Hold the handle with both hands and accelerate the
engine to high speed by throttle trigger.

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:
1. Stop the engine of the chain saw.
2. Operate the front and rear handles with your hands
(grip them lightly), so that the guide bar may be placed
at the height of about 40 cm as shown in fig.
3. 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.
4. 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 deteriores a little. Always
keep the device clean.
- Do not increase engine revolution while the chain
brake is engaged.
- Chain brake is used in emergencies. Do not use it
unless absolutely necessary.
- When using throttle latch at starting, keep the chain
brake position. And after starting the engine,
release the brake immediately.
