SAFETY
PRECAUTION WITH HIGH PRESSURE OIL
1
• Do not forget that the work equipment circuits are always under pressure.
• Do not add oil, drain oil, or carry out maintenance or inspection before com-
pletely releasing the internal pressure.
• If you are hit by a jet of high pressure oil, consult a doctor immediately for med-
ical attention.
• If oil is leaking under high pressure from small holes, it is dangerous if the jet of
high pressure oil hits your skin or enters your eyes. Always wear safety glasses
and thick gloves, and use a piece of cardboard or a sheet of wood to check for oil
leakage.
PRECAUTION WHEN CARRYING OUT MAINTENANCE AT HIGH TEMPERATURE OR PRESSURE
1
• Immediately after stopping machine operations, the engine coolant and oil are at high tempera-
tures and under high pressure. In this condition, if the radiator cap is removed, or the oil or cool-
ant are drained, or the filters are replaced, this may result in burns or other injury. Wait for the
temperature to go down, then carry out the inspection and maintenance in accordance with the
procedures given in this manual.
PRECAUTION WHEN USING HIGH PRESSURE GREASE TO ADJUST TRACK TENSION
1
• Grease is pumped into the track tension adjustment system under high pressure. If the specified
procedure for maintenance is not followed when making adjustments, the plug or grease fitting
may fly out and cause damage or personal injury.
• When loosening the grease drain plug, never loosen it more than one turn.
• Never put your face, hands, feet, or any other part of your body directly in front of any grease
drain plug or valve.

• Keep away from rotating parts and be careful not to let anything get caught in them. If your body
or tools touch the fan blades or fan belt, they may be cut off or sent flying, so never touch any ro-
tating parts.
WASTE MATERIALS

• Never dump waste oil in a sewer system, rivers, etc.
• Always put oil drained from your machine in containers. Never drain oil directly on the
ground.
