5.2 THROTTLE TRIGGER LEVER

It allows the activation of the chain.
The activation of the throttle trigger lever (Fig.
16.A), can only be used if the throttle lock
lever is pressed simultaneously (Fig. 16.B).
The cutting means stops automatically
when the throttle safety lever is released.

5.3 INTERLOCK LEVER

The throttle lock lever (Fig. 16.B) allows the
throttle trigger lever to be used (Fig. 16.A).

5.4 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.

6. USING THE MACHINE

The safety regulations to follow
are described in chap. 2. Strictly
comply with these instructions to
avoid serious risks or dangers.
IMPORTANT For instructions
regarding the motor and the battery (if
supplied), read the relevant manuals.

6.1 PRELIMINARY PROCEDURES

Before starting to work, it is necessary to carry
out several checks and operations to ensure you
can work efficiently and in maximum safety.
6.1.1 Checking the battery
Purchase the battery with the capacity that
most suits your operational requirements
and fully charge it according to the
instructions in the battery booklet.
The list of approved batteries for this machine
is found in the "Technical Data" table.
• Before each use:
– check the battery charge status according
to the instructions in the battery booklet.
6.1.2 Filling with chain lubrication oil
Fill with chain lubrication oil before using
the machine. For oil filling methods
and precautions see par. 7.3.
6.1.3 Checking the chain tension
Perform all operations
with the motor off.
Always wear heavy duty work gloves.
Check the chain tension.
The tension is correct when the drive links
do not slip out of the chain guides if you hold
the chain in the middle of the bar (Fig. 10).
To adjust the chain tension:
1. loosen the cover nut, using
the supplied wrench;
2. turn the chain tension adjuster screw
(Fig. 9.A) to achieve the desired tension;
-
3. raise the bar and tighten the guard nut
securely using the wrench supplied (Fig. 11.A).
Never work with the chain loose,
as it can be hazardous if the chain
slips out of the bar guides.
IMPORTANT During the first period of use
(or after replacing the chain) it must be checked
more frequently due to settling of the chain.
