GENERAL
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 hy-
draulic 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 disconnect-
ing hoses, stand to the side and loosen slowly
to gradually release the internal pressure before
removing.
Handling of the Accumulator
High pressure nitrogen gas is enclosed in the accu-
mulator and incorrect handling could possibly bring
about serious injury due to explosion. The following
matters should be strictly observed:
• Do not disassemble.
• Do not bring close to fire or throw into a fire.
• Do not make hole, weld, or fuse.
• Do not subject to shock such as hitting or rolling.
• At time of disposal, it will be necessary to release
the enclosed gas. Please contact a Takeuchi sales
or service agent.
Be careful with grease under pressure
E3A6201
The track adjuster contains highly pressurized
grease. If the tension is adjusted without following
the prescribed 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.
