Figure 12: Adjustment of blade drive tension pulley and belt guiding at the pulley
Travel clutch pulley (Figure 13)
With the lever on the left handlebar grip fully pressed down, the pulley must ensure a
sufficient belt tension (spring on the cable being extended by about 10 mm as compared
with the loose condition). Possible corrections are to be made by means of adjustment bolt
No. 4 (see Fig. 14). With the lever switched off, the pulley must be parallel to the
longitudinal machine axis. Wire in the tension pulley Bowden cable must not show any
slackness. In the case that the adjustment bolt is completely unscrewed and it is necessary
to tighten the V-belt, the spring on the cable can be hooked into the front hole on the arm
of the tension pulley (Note: this coupling can be used already from the manufacturer) and
belt tension can be adjusted once again. The V-belt must always go between two M6 bolts,
which form the belt guiding when the drive is switched off.
