PRECAUTIONS FOR MAINTENANCE SAFETY
46 PW160-7H VEAM390100
WARNING: For reasons of safety, always follow these safety precautions.
HANDLING HIGH-PRESSURE HOSES
● Do not bend high-pressure hoses or hit them with hard
objects. Do not use any bent or cracked piping, tubes or
hoses. They may burst during use.
● Always repair any loose or broken fuel hoses or oil hoses. If
fuel or oil leaks, it may cause a fire.
PRECAUTIONS WITH HIGH PRESSURE OIL
● Do not forget that the work equipment circuits are always
under pressure.
● Do not add oil, drain oil, or carry out maintenance or inspec-
tion before completely releasing the internal pressure.
● If oil is leaking under high pressure from small holes, it is dan-
gerous 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.
● If you are hit by a jet of high-pressure oil, consult a doctor
immediately for medical attention.
PRECAUTIONS WHEN CARRYING OUT MAINTENANCE AT
HIGH TEMPERATURE OR HIGH PRESSURE
● Immediately after stopping operations, the engine cooling
water and oil at all parts is at high temperature and under high
pressure.
In this condition, if the cap is removed, or the oil or water 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.
