WARNING! The following safety messages
address a potential Fire Hazard:
• Keep heat, flames and cigarettes away from
hydraulic oil.
• Clean hydraulic oil spills immediately.
• Stop the engine before replacing the
hydraulic oil.
• Wait until the engine is cool to the touch to
replace the oil.
WARNING! Exposure Hazard. Avoid skin
contact with the hydraulic oil. If your skin is
penetrated by high-pressure hydraulic oil,
seek medical attention immediately. Any fluid
injected under the skin must be removed
surgically or gangrene may result.
WARNING! The following safety messages
address a potential Burn Hazard:
• Relieve internal pressure by slowly rotating
the hydraulic tank filler cap during removal.
• Make sure the hydraulic tank filler cap is
closed properly after replenishment of the
oil.
• When filling the hydraulic oil tank, do not fill
above the upper limit on the level gauge.
Overfilling may cause oil to gush from the
tank during machine operation.
For oil type and usage specifications, see
“LUBRICATING OIL” on page 5-10.
Secure the hydraulic oil fill and drain plugs after oil
replacement. Use seal tape on the threads to
prevent leaks.
Place the machine on a flat, level surface in the
TRAVEL position when replacing or checking the
oil.
Do not start the engine until the hydraulic system
is completely filled with oil.
Prevent contaminants from entering the oil or oil
system.
Inspect O-rings for damage when removing
high-pressure hoses. Replace as necessary.
