check the dipstick at attached to the fill cap. The
hydraulic fluid should be at the notch on the dipstick.
CAUTION
DO NOT OVERFILL! DO NOT USE

PREVENTATIVE MAINTENANCE
Maintaining Hydraulic Oil Cooler Efficiency
Your machine is equipped with a hydraulic oil cooler, it is
integrated with the radiator and utilizes exhausted radiator air
from the engine fan to cool the hydraulic fluid. To maintain its
efficiency, periodically blow out the radiator & oil cooler fins
with compressed air. 100 p.s.i. is maximum
Changing The Hydraulic Fluid
1. Turn off the engine and engage the parking brake.
2. Place a drain pan on the floor below the reservoir.
3. Remove the hose and fitting located on the bottom
rear of the reservoir and allow the fluid to drain.
4. Discard the fluid in an approved manner, then replace
and reinstall the hose and fitting.
5. Remove the filler / breather cap located on top of the
reservoir and fill the reservoir with approved hydraulic
fluid.
