Eliminating Excessive Creeping of Unit
(Figure 16)
1. If hydraulic system is cold, run unit for a minimum
of five minutes, then shut off engine.
2. With unit up to and facing a wall, jack unit up so
that both drive wheels are off the ground.
3. Start engine and release parking brake.
4. Move steering levers from forward to reverse
several times to make sure controls are free. Then
return steering levers to neutral position.
5. Check wheel(s) for movement.
6. Shut off engine.
NOTE: The right and left steering levers are adjusted
the same. To access the tie-rod, place hood in the full
service position.
7. Adjust tie-rod(s):
If the wheel is moving in a forward direction:
a. Loosen jam nut on each end of tie-rod.
b. Turn tie-rod counter clockwise (lengthening the
distance between steering lever and hydrostatic
transmission) several times.
If the wheel is moving in a reverse direction:
a. Loosen jam nut on each end of tie-rod.
b. Turn tie-rod clockwise (decreasing the distance
between steering lever and hydrostatic
transmission) several times.
8. Close hood.
9. Start engine.
10.Move steering levers from forward to reverse
several times. Then return steering levers to
neutral position.
11.Shut off engine.
12.If wheel is not moving, tighten jam nuts on tie-rod.
The adjustment is complete.
13.If wheel is still moving, repeat steps 7 though 12.
ADJUSTING UNIT TO TRACK STRAIGHT
Check and adjust tire pressure. Increase pressure on
side unit tracks to. DO NOT exceed maximum
recommended tire pressure. See Specifications on
page 12 for correct tire pressure.
If tire pressure adjustment does not solve tracking
problem, adjust limiter bolts on stop bracket (Figure
17). Front bolts adjust forward tracking and rear bolts
adjust reverse tracking. Lengthen limiter bolt (move
closer to lever) on side which is too fast.

STEERING LEVER HANDLE HEIGHT
ADJUSTMENT
The handles have three height positions (Figure 18).
Figure 18
1. Remove spacer, handle, and eccentric spacer from
steering lever.
NOTE: Position the right and left handles at the same
height.
2. Install spacer, handle, and eccentric spacer in the
appropriate height position. Do not tighten nut
holding eccentric spacer.
3. Turn eccentric spacer until the right and left
handles are the same height. Tighten nut.
WARNING: This adjustment requires
operating engine and opening the hood (on
models 992318 and 319 the hood safety
interlock switch must be bypassed). Use
extreme care to avoid contact with moving
parts and hot surfaces. Be sure rear of unit is
well supported and secure before starting
engine.
WARNING: Prior to adjusting unit tracking,
shut off engine, engage parking brake, and
remove ignition key.
