ADjUsTIng The CUTTIng heIghT 

(PICTURe 3 PAge 8)

Proceed only after engine has been switched off and blade 

has come to a complete standstill.

• hold the adjustment lever firmly, tighten the lever to ensure 

unlocking, swing the lever towards the required position (5 

positions available), then slacken the action on the lever to allow 

the locking of the lever (picture 3 page 8).

On normal use the 4 wheels must be adjusted to the same 

height. however, the separate adjustment of each wheel 

makes it possible to adapt the cut to a possible unevenness, 

for example between the grass and an alley downwards, 

while preserving a perfectly horizontal shearing.

• This safety device controls the blade rotation of your self brush-

cutter mower. 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.

• Place behind the handlebar in working position and maintain your 

feet away from the cutting blade.

• Press the upper safety red lever against to the handlebar.

• Push the button and move the blade clutch control lever forward to 

engage the blade. The blade will remain engaged after the control 

lever has been released as long as the safety lever is kept pressed 

against the handlebar.

Don’t engage the blade when it’s in contact with long 

noncut grass as it could cause difficulties to start.

automatically braked and stopped within 3 seconds.

Release the safety lever to check if the blade stops 

immediately.

• Select the position 1 for a slow speed and 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 mower with the blade stopped. It’s the 

observation of your lawn which will guide you, choosing the 

optimal speed.

sPeeD ADjUsTMenT

• Select your speed and lock it in the position (1, 2 or 3).

loCKIng The DIffeRenTIAl

The differential can be locked to prevent the driving wheels from 

spinning and gain driving force on sloping ground or wet grass.

• Set the differential lock control lever to position [1].

• Bring the differential lock control lever back to position [0] to return 

to the active differential configuration and gain in handling capability.
