Second: Dismount the front plastic cover so that you can see the belt and disc drive pulley (Pict.11). (Marking (1) a (2) in pictures 10 and 11 are the
same and belong to the same cable.)
1) Tighten the belt by unscrewing the bolt
55
(1) in Pict.10 for approximately 1 mm in the direction of the arrow (away from the frame) and
repeat the check according to b). Continue tightening until condition b) is met and at the same time the belt transmission grip
56
stops while
wheel drive clutch lever is loose. If the bolt (1) cannot be unscrewed any further, screw it in completely against the direction of the arrow and
hook the spring at the end of the cable into a further opening in the pulley arm. Repeat tightening the belt until condition b) is met.
Check the automatic brake function after every adjustment!
2.5.4.1.1 V-belt exchange
Exchange the V-belt with a new one
57
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 Pict.13. Follow belt track around all guide elements!
Seek authorised service in case you lack appropriate manual skills.
2.5.4.2 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.
Do not continue working with the cutter unless you remove the automatic brake defect.
Seek authorised service in case you lack appropriate manual skills.
In case the brake does not stop the cutting disc in the given time span, it is necessary to adjust the brake cable (2) Pict.10 a 11. . Adjusting screw,
which tightens the brake cable (2) to the cutter frame Pict.10, needs to be screwed in against the direction of the arrow (towards the frame), so that the
axial clearance of the brake cable in the adjusting screw is 1 mm. Check the automatic brake function. If complete tightening the screw (2) does not offer
adequate brake effect, tighten the adjusting screw of the brake cable on the handlebars so that the axial clearance of the brake cable in the adjusting screw
is 1 mm. Check the automatic brake function
58
.
If, after the adjustment
59
, the brake does not work properly, contact an authorised service center.
