Doosan DX190W Operation And Maintenance Manual page 194

A. Cover inactive machine with tarpaulin if no suitable
shelter is available. Protect engine compartment,
transmission and hydraulics from entrance of dust.
B. In hot, damp, climates corrosive action will occur on
all parts of the machine and will be accelerated
during the rainy season. Rust and paint blisters will
appear on metal surfaces and fungus growth on other
surfaces.
C. Protect all unfinished, exposed surfaces with a film of
preservative lubricating oil. Protect cables and
terminals with ignition insulation compound. Apply
paint or suitable rust preventive to damaged surfaces
to protect them from rust and corrosion.
Operation in Dusty or Sandy Areas
Operation of the machine can cause dust in almost any area.
However, when in predominantly dusty or sandy areas,
additional precautions must be taken.
1. Keep cooling system fins and cooling areas clean. Blow
out with compressed air, if possible, as often as necessary.
Wear goggles when using compressed air.
2. Use care when servicing fuel system to prevent dust and
sand from entering the tank.
3. Service the air cleaner at frequent intervals, check air
restriction indicator daily and keep dust cup and dust valve
clean. Prevent dust and sand from entering engine parts
and compartments as much as possible.
4. Lubricate and perform services outlined on current
lubrication chart on machine and "Lubrication Chart and
Table" Section 4. Clean all lubrication fittings before
applying lubricant. Sand mixed with lubricant becomes
very abrasive and speeds wear on parts.
5. Protect machine from dust and sand as much as possible.
Park machine under cover or protect with tarpaulin to keep
dust and sand from damaging unit.
Operation in Rainy or Humid Conditions
Operation under rainy conditions is similar to that as in extreme
heat procedures listed previously.
1. Keep all exposed surfaces coated with preservative
lubricating oil. Pay particular attention to damaged or
unpainted surfaces. Cover all paint cracks and chip marks
as soon as possible to prevent corrosive effects.
