SAFETY
PRECAUTIONS FOR MAINTENANCE
2-27
PRECAUTIONS WITH HIGH-PRESSURE OIL
Diesel fuel or hydraulic fluid under pressure can penetrate the skin or eyes and cause serious injury, blindness or
death. Fluid leaks under pressure may not be visible. Use a piece of cardboard or wood to find leaks but do not
use your bare hand.
q
Do not forget that the work equipment circuits are always under pressure.
q
Do not carry out any inspection or replacement operation before the pressure has been completely removed.
q
Check for cracks in the piping and hoses and for swelling in the hoses.
q
Always wear safety glasses and leather gloves.
q
If you are hit by a jet of high-pressure oil and suffer injury to
your skin or eyes, wash the place with clean water, and
consult a doctor immediately for medical attention.
PRECAUTIONS WHEN USING HIGH-PRESSURE GREASE TO ADJUST TRACK TENSION
Grease inside the track shoe tension adjuster is highly pressur-
ized. Do not make an error in the track shoe tension adjust-
ment steps, because a serious personal injury can be caused
by an error. Be sure to follow the steps correctly.
q
When discharging grease to loosen the track shoe tension,
do not loosen plug (1) more than one turn. Otherwise, plug
(1) may suddenly spring out.
q
Do not bring the face, hand, foot or other part of your body
near plug (1).
DO NOT DISASSEMBLE RECOIL SPRING
Do not disassemble the recoil spring as a cushion for the front idler. It is built in with a special jig, and if disassem-
bled carelessly, it will be ejected, causing a serious personal injury.
