SAFETY PRECAUTIONS 1B0BF00
Be careful with oils under pressure
Pressure is maintained in the hydraulic circuit long after
the engine has been shut down.
• Do not fill with, dispose of fuel/oil, or perform the in-
spection and maintenance until the internal pressure is
completely released.
• The hydraulic oil escaping from a small hole can be
hazardous if contacted. It is under high enough pres-
sure to penetrate the skin or eyes and cause serious
injury. If leak is suspected, protect your eyes and skin
by wearing protective glasses and thick gloves to
search for a leak. Also use a paperboard or plywood
to keep your skin from oil spurting. If oil penetrates the
skin, it must be surgically removed within a few hours
by a doctor familiar with this type of injury.
Release internal pressure before working on the
hydraulic system
Oil may spurt out if caps or filters are removed or pipes
are disconnected before releasing the pressure in the
hydraulic system.
• Gradually loosen the vent plug to release the internal
pressure of the hydraulic oil tank.
• Move all the control levers and pedals several times in
all directions to release the pressure from the circuit of
the working equipment (for link type controls).
• When removing plugs or screws, or when disconnect-
ing hoses, stand to the side and loosen them slowly to
gradually release the internal pressure before remov-
ing.
Be careful with grease under pressure
In the track adjuster, the grease has been injected under
high pressure. 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 put your face, arms, legs or body in front of the
grease discharge valve.
Handling of the accumulator
Be sure to handle the high-pressure nitrogen gas en-
closed in the accumulator with care according to proce-
dure. If handled incorrectly, it could explode and cause
serious injury. Strictly observe the following precautions:
• Do not disassemble.
• Do not allow flame near it or throw it into a fire.
• Do not drill, weld or fuse.
• Do not subject it to physical shock such as hitting, roll-
ing or dropping.
• Before disposing of the unit, the sealed gas must be
drained. Contact your sales or service dealer for help
with this.
Disconnect the battery
Disconnect the wiring from the both terminals (+ and -)
on the battery before working on the electrical system or
doing electric welding. Otherwise, short-circuit and ex-
plosion of the battery can result.
