6.5 Adjusting the wires of pulley, brake and wheel drive clutch.
In order to guarantee low operating forces on levers which control the drive switching, it
is advisable to lubricate the wires in Bowden cables at least 2x during the season with some
of oils available in atomiser (e.g. SILKAL, MD Spray, WD40). Correct functioning of the
machine also requires correct adjustment of drive controls.
The wire in the Bowden cable must always exhibit a slight slackness of approx. 1 mm
(with the lever of the cutting disk drive clutch and brake released) so that the brake
performance is sufficient. In order to achieve clearance of the brake wire in the Bowden
cable, adjustment bolts have to be screwed into the chassis or handlebars crossbeam at the
adjustment.
The wires in the Bowden cable of pulley and in the Bowden cable of wheel drive clutch
must be without slackness, slightly tense. In order to make the wires tense, adjustment bolts
have to be screwed out of the chassis or handlebars crossbeam at the adjustment.
Safety nuts in all adjustment bolts should be tightened by using two flat wrenches No.
10 or 9 (in accordance with the size of the M6 nut used). If there is no more step to be used in
the adjustment bolt, it is possible to displace the hook on the wire into another hole in the
sheet-metal lever on the handlebars (or on the wheel drive clutch lever on the gearbox and on
the arm of the tightening pulley – see Figs. 9 and 10) so that the initial tension of the wires
can be again regulated by the adjustment bolt.
