CUTTING HEIGHT ADJUSTMENT
Proceed only after engine has been switched off.
• Push the handlebar downwards to reduce the control effort.
• Operate the cutting height adjustment control (a picture 10).
• Lower or mount the handlebar to the desired height (3 positions) (b
picture 10).
• Release the cutting height adjustment control.
STARTING AND STOPPING THE BLADE
BLADE BRAKE CLUTCH
• This safety device controls the blade rotation of your self-pro-
pelled brush-cutter. The machine drive can also be used apart
from blade rotation, specially when taking the machine outside
the cutting area.
USE
Before you engage the blade, make sure that the engine
is warm enough and that it’s running at the maximum run
(throttle control lever on [MAX] position).
• Stand behind the handlebar in working position and keep your feet
away from the cutting blade.
• Push the red safety button to the right and hold it (1 picture 11).
• Apply the blade clutch control lever to the handlebar (2 picture 11),
then release the safety button. The blade will remain engaged after
releasing the safety button as long as the clutch lever is held against
the handlebar.
Don’t engage the blade when it’s in contact with long uncut
grass as it could cause difficulties to start.
BLADE STOP
• Release the blade clutch lever to stop blade rotation. The blade will
be automatically braked and stopped within 7 seconds.
PARKING BRAKE (A PICTURE 12)
This security feature locks the wheels so as to immobilise your brush-
cutter.
• To engage the parking brake, pull the brake lever towards the back of
the machine and release it from its lock.
• To release the parking brake, pull the brake lever back and engage it.
DRIVE SPEED ADJUSTMENT
The hydraulic transmission enables the drive to be adapted to all
cutting conditions through progressive speed variation controlled by
the control lever.
Opt for a slow speed (position 1) when the conditions of use are diffi-
cult (wet grass, high or too dense, uneven ground).
Select a superior position (position 2 or 3) for a high speed if
the conditions of use allow it: dry grass, neither too high nor too
dense, flat ground or displacement of the brush-cutter with the blade
stopped.
It is the observation of your terrain that will guide you in choosing
the optimal speed of advancement.
SPEED ADJUSTMENT
• Move the selector lever located on the left of the dashboard (a picture
13) in the notched position corresponding to the selected speed range
(1, 2 or 3).
DRIVE CONTROL
To move
• Act on the control lever (b picture 13). The speed is at maximum
when the control lever is closed to the handlebar.
• To stop position, release the lever.
Go reverse
• To go into reverse, release the control lever. Pull the reverse lever
(c picture 13) backwards. The speed of recoil is maximum when the
speed selector is maintained in rear stop, it will be even more reduced
that the reverse command will be accompanied to the initial position.
• To stop the machine, release the reverse control lever.
Be particularly careful when you use the reverse gear: disen-
gage the blade, and do not let yourself be surprised by the
machine’s movement.
Disengagement of transmission
• Pull the by-pass control to [0] position (b picture 12).
• Do not forget to switch the control to position [1], to be able to use
the transmission drive again.
DIFFERENTIAL LOCK CONTROL
The differential can be locked to prevent the driving wheels from
spinning and gain driving force on sloping ground or wet grass.
• Actuate the differential lock control lever (picture 14).
• Release the differential lock control lever to return to the active diffe-
rential configuration and gain in handling capability.
Pay special attention when changing direction when using
the differential lock.
BLOCKING THE IDLING WHEELS (AH75)
In order to guarantee a good trajectory in reverse, the rotation of the
idling wheels must be locked with the latch (picture 15).
CUTTING - PRECAUTIONS FOR USE
ON SLOPES
• Place the throttle control lever on [MAX] position.
• Engage the blade (double safety control).
• Engage the drive control lever.
Never touch the blade when it is rotating.
