3.5.4 BELT TRANSMISSION – AUTOMATIC BRAKE
The cutter is equipped with modern belts that do not require special care. It is only necessary to control them regularly and exchange
them should you see cracks or breaks on their surface. It is necessary to check on the tightening pulleys setting after the first 5 hours of
operation, as the belt is being run-in. It is necessary to check the tightening pulleys function during the running-up, in order to prevent belt
damage caused by insufficient tension when the belt extends. It is also important to check the function of the automatic disc brake during
the running-up.
The correct belt transmission function is easy to check:

If you had problems with at least one of these, the tightening pulleys need adjustment as per N!P!O!L.

In case the tightening pulleys cannot be adjusted to prevent belt slipping, it is necessary to exchange the belt.

3.5.4.1.1 V-BELT EXCHANGE
Exchange the V-belt with a new one
98
every time you see cracks or breaks in its surface, or when it is so deteriorated that it cannot be
tightened with the tightening pulleys. Exact instructions for belt exchange are not included here, as their contents exceed the limitations of
this manual. When exchanging the belt, follow
"!MR
. Follow belt track around all guide elements!

3.5.4.2 BRAKE FUNCTION CONTROL AND ADJUSTMENT
Check the automatic brake function after every 10 hours of use. (Current control can be done during operation.) Every time you release
the disk drive clutch lever, the automatic brake must stop the disc within 5 sec.

Use V-belts recommended by the manufacturer only. Proper transmission function cannot be guaranteed when using other V-belts.

You may follow opposite instructions. First tighten the screw of the brake cable (towards handlebar rail) on the handlebars so that the axial clearance in the adjusting screw is 1 mm.
LRR
The condition of the axial clearance of the brake cable in the adjusting screw is met.
