DJUSTING THE TENSION OF THE DRIVE BELT
If you should notice that forward drive power has dropped, it will be necessary to
adjust the tension of stretcher’s spring to return to top operational conditions.
Access for making this adjustment is by taking off the inspection hatch on the tun-
nel beneath the seat.
Loosen the locking nuts (2) and tighten or loosen the screw (1) as much as nec-
essary for a length «A» of the spring (3) of:
A = 129 - 131 mm
A = 109 - 111 mm
measured to the outside of the end of the spring.
When the adjustment has been made, tighten the
nuts (2).
When replacing the belt, take
great care when using for the first few times as
engagement may be sudden until the belt is sufficiently run in.
