other parts will also become hot. Beware of scald (As
figure 1.27).
2) Carry out inspection and maintenance after oil and parts
are cooled to prevent scald. The hydraulic oil tank and
pipeline are high pressured, before maintenance or
replacement, it should release the pressure to avoid hot
oil erupting.
1.28 BE CAREFUL TO PRESSURE LIQUIDS
1) Effluent liquids in high pressure will penetrate through skin,
causing GBH (As figure 1.28.1).
2) Release pressure before disjoining liquids or other
pipeline to avoid this danger. Operate control lever
many times to release pressure.
3) Before supercharging, tighten all the connections.
4) Inspect leakage with cardboard, make sure to protect
your hand and body against touching high pressure
liquids (As figure 1.28.2).
5) If accident occurs, see the doctor at once.
6) Any liquid penetrated in skin must be cleaned within few
hours. Otherwise it will cause necrosis.
1.29 NO HEATING NEAR PRESSURE OIL PIPE
1) If heating near pressure oil pipe, the inflammable spray will cause
severe burn to nearly people. Don’t carry out welding, gas
protection welding, or gas cutting near pressure oil pipe or other
flammable goods.
2) If it is a must to carry out welding, gas protection
welding, or gas cutting near pressure oil pipe, it should
mount temporary fireproof jacket to protect hose or other
materials (As figure 1.29).
