OPERATING! Add hydraulic oil to operating
level before use. Do not overfill.
To check the hydraulic oil level:
1. Park the unit on a level surface.
2. Start the unit and run it to operating
temperature (about 10 minutes).
3. Cycle the hydraulic cylinder in and out
two or three times.
4. Shut off engine.
5. Remove any dirt that may be around the
cap/breather on the hydraulic reservoir.
6. Remove cap/breather and wipe oil level
dipstick clean.
7. Replace cap/breather and fully tighten.
8. Remove cap/breather and check oil
level on dipstick. Oil should be within the
operating range. See
Figure 19.
9. Add hydraulic oil as necessary. Do not
overfill.

WARNING: HYDRAULIC FLUID
can result in severe burns. Fluid in
hydraulic system can penetrate
skin and result in serious injury or
death.
Be sure to stop the engine and
relieve hydraulic pressure before
doing any work on hydraulic parts.
Keep body and hands away from
pin holes or nozzles which expel
hydraulic fluid when under
pressure. Use paper or cardboard,
not hands, to search for leaks.
Ensure all hydraulic fluid
connections are tight and all
hydraulic hoses and lines are in
good condition before applying
pressure to system.
FOREIGN FLUID INJECTED
INTO BODY can result in
gangrene. Fluid must be surgically
removed within a few hours by a
doctor familiar with this form of
injury.
