5.1 THROTTLE TRIGGER LEVER (Fig. 14.A)
It allows the activation of the chain.
The activation of the throttle trigger lever is
possible only after that the throttle lock buttom is
pressed (Fig. 14.B).
The cutting means stops automatically
when the throttle safety lever is released.
5.2 INTERLOCK BUTTOM (Fig. 14.B)
It allows the throttle trigger buttom to be used (Fig.

5.3 CHAIN BRAKE
This is a safety braking system that blocks the
chain movement when kickback occurs during
cutting. Kickbacks occur following an irregular
contact of the tip of the bar, with a rapid upward
movement of the bar that causes the hand to
strike the front guard (Fig. 1.D)
It must be manually released to disengage the
chain brake.
Chain brake engaged.
This is achieved when the
front hand guard is pushed
all the way forward.
Chain brake disengaged. This
is achieved when the front hand
guard is pulled all the way back,
towards the machine body,
until it clicks into position.
Do not use the machine if the chain
brake does not function correctly and
have it inspected by your dealer.
