• If adjustment is needed to drive
handles loosen jam nuts with ½"
wrench and turn control rod to
proper length. Retighten jam nuts
to lock rod in place. See Figure 40
2. To make the machine drive straight:
•
Tighten both dump valve nuts
snug. See Figure 38 from towing
the machine for location.
•
Test drive machine in open,level,
clear area. Set Speed-lock to 3
or less and hold handles firmly
against Speed-lock bar.
• Note what direction the machine
tends to drift. If machine drifts left
loosen right hand dump valve nut.
If machine drifts right loosen left
hand dump valve nut. Work in ¼
turn increments; dump valve nuts
are sensitive. Do not have both
nuts loose or a loss of power will
result.
3. Parking brake adjustment:
•
The only adjustment is to the
linkage system, the internal wet
disk brake is not adjustable on the
wheel motor.
•
To adjust the linkage, loosen jam nuts with ½" wrench
and turn control rod to tighten or loosen. Retighten jam
nuts and confirm that brake still engages, disengages, and
handle moves freely.
Replacing Hydraulic Oil & Filter
(First 100 hours and every 500 hours after)
WARNING!
Hydraulic Oil is hot during normal
operation and can burn. Do not open hydraulic
system with hot oil under pressure!
Note
: It is impossible and unnecessary to drain the entire
hydraulic system. This procedure will replace enough of the
oil to preserve the life of the unit.
1. Block front tires and jack rear of unit per jacking
instructions. With unit cool to slightly warm locate the oil
supply hose as shown in Figure 41.

2. With a catch pan in place, use a 1" wrench to remove the
hose at the valve end, supporting the other end of the valve
fitting with a backhold wrench to prevent movement.
3. Feed the loose end of the hose behind the covers to a
suitable drain pan.
4. Remove rear tires with a ¾" socket and loosen lower
motor hose on each side as shown in Figure 43 with a ⅞"
wrench. Route hose to an appropriate catch pan.
Figure 42: Motor hose location
5. Remove spark plug wires from engine to allow it to crank
but not run.
6. Crank engine to allow pump to move fluid trapped in
system to be removed. Crank for 5 seconds at a time,
allowing starter to rest for 30 seconds in between cranks.
Engage drive handles in reverse while cranking.
7. Stop cranking when hydraulic reservoir is empty. Do not
continue to crank with reservoir dry.
8. Locate and remove the hydraulic oil filter under the dash.
Be careful not to spill the oil in the filter. Pre-fill new filter
with fresh oil, allowing filter paper to absorb the oil before
reinstalling.
NOTE: Filter must be replaced with same size and type (10
micron) or warranty is void. See Figure 43.
