Inspect the entire hydraulic system for leaks. Areas to inspect include the motors and
pumps, the filter, tank, and coolers, the deck lift arm cylinder (under the front left of the
frame), all hoses, clamps, and fittings, and the entire area under the hydraulic system. If
any leaks are discovered, allow ample time for the hydraulic fluid to cool. Repair or
replace the defective parts and re-fill the hydraulic system before operating the Articula-
tor. Be sure to close the engine cover, and secure all latches.
3.10 Hydrostatic Pump Adjustment
Danger
DANGER!

Always use jack stands when adjusting the hydrostatic pumps!

Keep everyone clear of all controls while adjusting the hydrostatic pumps!
Occasionally, you may need to adjust the hydrostatic pumps to keep the drive wheels
from creeping. Follow these procedures to adjust the pumps:
1. Lift the rear of the drive unit until the drive tires clear the ground. Use jack stands for
safety.
2. Be sure steering control arms are locked in neutral position.
3. Start the drive unit, and set the throttle
arm to 3/4 full.
4. If either drive tire rotates, you need to
adjust the hydrostatic pump link arm
for that tire. The link arm is attached
to the bottom of the steering control
arm and the pump.
To adjust the link
arm, loosen the jam nut from the
hydrostatic pump link arm. Slowly turn
the link arm, watching the tire as it
turns. If the tire begins turning faster,
turn the link arm in the opposite direc-
tion until it slows, and eventually
stops. Tighten the jam nut to lock the
link arm into this position.
5. When finished, turn off the drive unit.
6. Be sure that both link arm jam nut on both sides are tight.
7. Lift the drive unit, remove the jack stands, and lower the unit to the ground.
