Troubleshooting, Adjustments, & Service

SEAT ADJUSTMENT

The seat and ground speed control levers should be
adjusted so that operator’s elbows are supported by the
arm rests when his/her hands are on the controls, and
the ground speed control levers can be moved through
their full range of motion without contacting the opera-
tor’s legs.

Seat Position Adjustment

The seat can be adjusted forward and back. Move the
adjustment lever (A, Figure 20) towards the left hand
side of the machine, slide the seat to the desired posi-
tion, and release the lever.

GROUND SPEED CONTROL LEVER
ADJUSTMENT

The control levers can be adjusted in three ways. The
alignment of the control levers, the placement of the
levers (how close the ends are to one another) and the
height of the levers can be adjusted.

To Adjust the Handle Alignment:

Loosen the mount

bolts (A, Figure 21) and pivot the lever(s) (C) to align with
each other.

To Adjust the Handle Placement:

Loosen the jam nuts

and adjust the placement bolt (B, Figure 21) in or out to
properly adjust the lever end spacing.

To Adjust the Handle Height:

Remove the mounting

hardware and reposition the handle either up or down
from its original position. You will need to readjust the
handle alignment as described above.

SPEED BALANCING ADJUSTMENT

If the rider veers to the right or left when the ground
speed control levers are in the maximum forward or
reverse position, the top speed of each of these levers
can be balanced by turning the adjustment bolt(s) (A & C
Figure 22). Only adjust the speed of the wheel that is
traveling faster.

TO REDUCE THE SPEED OF THE FASTER WHEEL

1. Loosen the jam nut securing the top speed adjust-

ment bolt (A, C).

2. Turn the top speed adjustment bolt COUNTER-

CLOCKWISE to reduce the speed.

3. Retighten the securing nut when adjustment is com-

plete.

WARNING

DO NOT adjust the rider for a faster overall speed
forward or reverse than it was designed for.
