Be careful with fluids under pressure
Pressure can be maintained in the hydraulic circuit
long after the engine has been shut down.
• Release all pressure before working on the hydrau-
lic system.
• Hydraulic fluid under pressure can penetrate the
skin or eyes and cause injury, blindness or death.
Fluid escaping from a small hole can be almost
invisible. Wear a safety goggles and heavy gloves
and use a piece of cardboard or wood to search for
suspected leaks.
If fluid is injected into the skin, it must be removed
within a few hours by a doctor familiar with this
type of injury.
Release all pressure before working on
the hydraulic system
Oil may spurt out if caps or filters are removed or
pipes disconnected before releasing the pressure in
the hydraulic system.
• Gradually loosen the vent plug to relieve tank
pressure.
• Move all the control levers and pedals several
times in all directions to release the pressure from
the working equipment circuitry. (For link type
controls)
• When removing plugs or screws or disconnecting
hoses, stand to the side and loosen slowly to gradu-
ally release the internal pressure before removing.
Be careful with grease under pressure
The track adjuster contains highly pressurized grease.
If the tension is adjusted without following the pre-
scribed procedure, the grease discharge valve may fly
off, resulting in injury.
• Loosen the grease discharge valve slowly. Do not
unfasten it more than one full turn.
• Do not put your face, arms, legs or body in front of
the grease discharge valve.
Disconnect the battery
Disconnect the battery before working on the electri-
cal system or doing any welding. Remove the nega-
tive (–) battery cable first. When reconnecting the
battery, connect the negative (–) battery cable last.
