D2) FORWARD BELT
Remove the brake adjustment device (Fig.7 Ref. A) by unscrewing the screw (Fig. 7 Ref. B),
slip off the rotor engagement belt (Fig.12 Ref. A) by turning the engine pulley anticlockwise.
Slip off the "FORWARD" belt (Fig. 11 Ref. A) from the large pulley side (Fig. 11 Ref. B) , by
turning the engine pulley anticlockwise (Fig. 11 Ref. C).
Fit on a new belt by slipping it onto the engine pulley (Fig. 11 Ref. C) first, then onto the other
(Fig. 11 Ref. B), switch on the engine and make sure that the forward clutch engagement
lever (Fig. 1 Ref. A) is released and that in this condition the belt does not work. Should the
belt engage move the engine slightly towards the front of the machine by unscrewing the
fixing nuts (Fig. 13 Ref. A)
When retightening the nuts after making this adjustment make sure that the two pulleys (Fig.
11 Ref. B, Ref. C) are perfectly aligned.
