Step 3 - Check the chain brake
This machine is equipped with a chain brake that will immediately disable the chain
upon the occurrence of kickback during cutting. The brake is automatically operated by
inertia forces, which act on the weight fitted inside the front guard. This brake can also be
operated manually with the front guard pushed forward to the guide bar. To disengage the
chain brake, pull it back until it touches the front handle.

IMPORTANT! Be sure to test brake operation every time you use the machine
and occasionally during the period of use.
How to confirm if the chain brake is functioning correctly
1. Turn off the engine and leave until cold.
2. With the chainsaw on a flat surface and the chain tensioned correctly, engage the
chain brake by pushing it forward until an audible click is heard. Then, wearing
protective gloves, attempt to move the chain by hand in the direction of normal rotation;
if this is not possible, the chain brake has been engaged. If the brake is engaged when
the chain is rotating at high speed for extended periods of time this can cause damage
to the clutch or for it to fail completely. When the brake is activated whilst cutting,
immediately release it, having first released the throttle lever, and set the chainsaw to
'STOP'.

Step 4 - Stop the engine
switch
1. Release the throttle lever to allow the engine to idle for a few seconds.
2. Set the switch to the 'STOP' position.
IMPORTANT! Do not put the chainsaw on the ground when it is still running. For
additional safety, switch the chainsaw off when not in use or between cuts. In the
event that the ignition switch will not stop the saw, pull the choke control out and
engage the chain brake to stop the engine. If the ignition switch does not stop
the saw when set to the 'STOP' position, have the ignition switch repaired before
using the chainsaw again, to prevent unsafe conditions or serious injury.
NOTE: When you have finished using the saw, always relieve the tank pressure by
loosening, then retightening, the chain oil and fuel mix caps. Allow the engine to cool before
storing.
Step 5 - Sawing
WARNING!
Before proceeding to your job, read the 'Safety instructions' section. It is
recommended to first practice sawing easy logs. Ensure your logs are securely
placed, using a saw or logging horse. This also helps you get accustomed to
your unit. Always follow the safety regulations. This chainsaw is designed to cut
wood ONLY. Cutting any other materials with this machine is DANGEROUS and
will damage the machine. Vibrations and kickback will vary with materials other
than wood, and the requirements of the safety regulations would not be met. Do
not use the chainsaw as a lever for lifting, moving, or splitting objects. Do not
lock it on a fixed stand. It is strictly forbidden to attach any accessories to this
product other than those supplied by the manufacturer.
It is not necessary to force the saw into the cut. Apply only light pressure while
running the engine at full throttle.
