4.2 BLADES BRAKE ADJUSTMENT
Disengaging the blades causes a brake to come
into action. This is to stop the blade turning within
five seconds.
Longer braking times do not comply with safety
regulations, but adjusting the brake so that it
stops more quickly than this can cause premature
wear of the brake pad ( 
➤in models with lever
operated engagement) or the slipping of the...

4.3 BRAKE ADJUSTMENT
Reduced braking power is corrected by adjusting
the spring on the brake rod, which is reached
through the inspection hatch beneath the seat.
The adjustment is to be made with the parking
brake engaged and consists of altering the length of
the spring 
(4)to the best measurement. The braking
capacity is increased by screwing the nut 
(3)down
on the rod (and thus shortening the length of the...

If it seems that the forward drive is not working
properly after a long period of use or after replac-
ing the belt, this may be caused by a change in the
length of the belt.
–A loose belt reduces output from the drive and
limits forward movement power;
–a belt which is too tight increases noise and
results in jerky movements or tipping up when
engaging...

order to get the correct travel for the pedal and to
reach the envisaged speeds both forwards and in
reverse.

cutting deck is parallel with the ground crosswise,
and slightly lower at the front.
Two types of adjustment are possible:
a)combined adjustment to the parallel and mini-
mum front and rear...

The steering allowance should never be excessive
if driving is not to be impaired.
Check that the movement is not caused by loose
linkage nuts and tighten all the nuts of the tie-rods
and ball joints.
If the movement is due to the ring gear / pinion cou-
pling, it will be necessary to adjust the arrangement
of the set of blocks between the ring gear and the
frame.
