SWDM40 OPERATION & MAINTENANCE MANUAL
1.7.13 Preventing Inhaling Asbestos Dust
1 Prevent inhaling possible asbestos dust. The asbestos fiber may cause lung cancer
2 Some seals contain asbestos fiber. In these components, normally, the asbestos is in
the resin or kept closed. If the asbestos containing parts don’t cause dust, there isn’t
any danger in normal disposal
3 In order to prevent dust, don’t clean with compressed air, and avoid brushing and
grinding asbestos-contained materials. In maintenance work, wear regulated respirator,
and use a special dust collector to clean asbestos. If dust collector is not available, use
a little oil or water to damp the asbestos-contained material. Comply with working
area rules and asbestos disposal rules. Keep other people from entering in working
area.
1.7.14 Be Cautious of Inhalation of Smoke or Exhaust Gas
1 Inhaling exhaust gas may cause disease, or even death
2 If the machine is operated inside a building, open windows and doors to ensure
sufficient ventilation, or use long exhaust pipe to discharge smoke
1.7.15 Preventing Scald
1 During operation, engine oil, gear oil, hydraulic oil and cooling water will become hot.
Also engine, hose, exhaust pipes, and other parts will also become hot. Beware of
scalding
2 Carry out inspection and maintenance after oil, water and parts have cooled to prevent
scalding. The hydraulic oil tank and pipeline are high pressured. Before maintenance
or replacement, the pressure should be released to avoid hot oil erupting.
1.7.16 Be Cautious of High Pressure Liquids
1 Liquids in high pressure can penetrate through skin, causing GBH.
2 Release pressure before disconnecting any pipes to avoid the danger
3 Operate control lever many times to release pressure.
4 Before pressurizing, tighten all the connections.
5 Inspect leakage with cardboard. Pay attention to protect your hand and body.
6 If accident occurs, see a doctor at once.
7 Any liquid penetrating the skin must be cleaned within a few hours, otherwise it will
cause tissue decay.
1.7.17 Be Careful of High Pressure Gas
1 High pressured heat quality can cause serious injury accidents.
2 Air pipeline can be repaired and maintained by air defense
