Checking drive pedal
A linkage connects the drive pedal to the shift
lever (2) on the transmission (7). When the drive
pedal is not actuated, the shaft-mounted leg
spring (6) always returns this lever to the center
position .
When at the center position, the drive pedal ad-
justment should provide for equal angles from
the horizontal for both forward and return foot-
rests.
An adjusting screw (8) beneath the drive pedal
limits pedal travel and, at the same time, the max.
drive speed (see technical specifications).
Note:
This limit must be observed especially in the
case of units licensed for road travel.
It is essential that the shaft-mounted leg spring
(6) securely rests against the dog pin (4) and
stop pin (5), and that it does not slip past these
two limiters (check intermediate plate (3)).
With the drive pedal at center position and with
the parking brake released, the unit may move
neither forward nor backward.
The drive pedal must travel without jerking or
binding.
Note:
All adjusting screws must be fixed with seal-
ing lacquer.
