SAFETY
Maintenance
Precautions
Be careful with hot cooling
systems
E3A540
Do
not remove the radiator cap or drain plugs
when the coolant
is
hot. Stop the engine, let
the engine and radiator cool, and loosen the
radiator cap or drain plugs slowly.
Be careful with fluids under
pressure
Pressure can be retained
in
the hydraulic
circuit long after the engine has been shut
down.
• Release
all
pressure before working on
the hydraulic system.
• Hydraulic fluid under pressure can
penetrate the skin and eyes and cause
injury, blindness or death. Fluid escaping
from a small hole can be almost invisible.
Wear 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.
32
Release all pressure before
working on
the
hydraulic system
Oil
may spray out if caps or filters
are
removed
or pipes disconnected before releasing the
pressure
in
the hydraulic system.
• When removing plugs and screws and
disconnecting hoses, stand to the side
and loosen slowly to gradually release the
internal pressure before removing.
Be careful with grease under
pressure
E3A620
The track adjustercontains 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 put your face, arms, legs or body
in
front
of
the grease discharge valve.
• If no grease
is
expelled when grease
discharge valve
is
loosened, there
is
a
problem. Contact your nearest service
outlet for repairs.
DO
NOT disassemble,
because this
is
very dangerous.
