Chain brake (FIG 18)
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(Pic. b). To disengage the chain-brake, pull it back until it
touches the front handle.
Important: Be sure to confirm brake operation every time you use
the machine and periodically 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"."
With the chainsaw switched off the chain oil flow can be changed
by inserting a screwdriver in the hole on the bottom of the side of
the clutch. Increase or decrease the oil flow (See Fig 17) according
to your work conditions. Restart the chainsaw and check the rate
of flow meets your requirements.
