and add fluid to raise the level to the mark on
the dipstick. Do not over fill the tank.

Checking the Hydraulic
Lines
After every 25 operating hours, check the hydraulic
lines and hoses for leaks, loose fittings, kinked
lines, loose mounting supports, wear, weather,
and chemical deterioration. Replace all moving
hydraulic hoses every 1500 hours or 2 years, which
ever comes first. Make necessary repairs before
operating.
Hydraulic fluid escaping under pressure
can penetrate skin and cause injury. Fluid
injected into the skin must be surgically
removed within a few hours by a doctor
familiar with this form of injury or gangrene
may result.
• Keep your body and hands away from
pin hole leaks or nozzles that eject high
pressure hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks, never use your hands.

Cleaning

Removing Debris from the
Traction Unit
Important: Operating the engine with a
blocked radiator, may result in engine damage
from overheating.
1. Park the traction unit on a level surface, raise
the loader arms, and install the cylinder locks.
2. Stop the engine and remove the key.
3. Remove the front access cover.
4. Clean any debris from the grill.
5. Open the rear access cover.
6. Wipe away debris from the air cleaner.
7. Clean any debris build-up on the engine with a
brush or blower before each use.
Important: It is preferable to blow
dirt out, rather than washing it out. If
water is used, keep it away from electrical
items and hydraulic valves. Do not use
a high-pressure washer. High-pressure
washing can damage the electrical system
and hydraulic valves or deplete grease.
8. Replace and secure the front and rear access
covers.
9. Remove and store the cylinder locks and lower
the loader arms.
