Doosan Compressor HP1300WCU

Bare Airend -- Pertains to major airend parts (rotors, housings, and bearings).

Airend Components -- Pertains to auxiliary attachments to the bare airend (drive coupling, seals, pumps, valves, tubes, hoses, fittings and filter housing).

The compressor oil must be replaced every 500 hours of operation or six (6) months, whichever comes first for models HP600 -- P1600.

Refer to the fluids and lubricants chart for ambient temperature ranges and specifications, in the lubrication section of this manual.

WARNING: Do not remove the cap from a HOT engine radiator. The sudden release of pressure from a heated cooling system can result in serious personal injury.

The engine cooling system is filled at the factory with a 50/50 mixture of water and ethylene glycol. This permanent type antifreeze contains rust inhibitors and provides protection to --35° F (--37°C).

The use of such a mixture is recommended for both summer and winter operation. When using water alone, be sure to add a reputable brand of rust inhibitor to prevent internal corrosion.

Is the coolant mixture 50/50 water and ethylene glycol?

Is rust inhibitor added when using water alone?

It is recommended to test the freezing protection of the coolant every six months or prior to freezing temperatures. Replenish with a fresh mixture every twelve months.

Has the freezing protection of the coolant been tested?

Has the coolant been replenished with a fresh mixture?

A drain for the system is located in the bottom radiator tank. An alternate method would be to disconnect a bottom radiator hose.

Fasteners, Guards Check: Visually check entire unit in regard to bolts, nuts and screws being properly secured. Spot check several capscrews and nuts for proper torque. If any are found loose, a more thorough inspection must be made.

Air Cleaner Elements: Check when indicated.

Engine: Replace oil changes, oil & fuel filters, etc.

WARNING: High pressure air can cause serious injury or death from hot oil and flying parts. Always relieve pressure before removing caps, plugs, covers or other parts from pressurized air system.

The scavenge line originates at the receiver--separator tank cover and terminates at the compressor airend through an orifice. Once a year or every 2000 hours of operation, whichever comes first, remove this line and any orifice, thoroughly clean, then reassemble.

NOTICE: Excessive oil carry-over may be caused by an oil-logged separator element. Do not replace element without first performing the following maintenance procedure:

Check oil level. Maintain as indicated earlier in this section.

Thoroughly clean scavenge line, any orifice and check valve.

Assure minimum pressure valve (if so equipped) has proper setting.

Run unit at rated operating pressure for 30 to 40 minutes to permit element to clear.

Warning: This procedure requires trained personnel with PPE!

Trailer secured on adequate capacity jack stands

Adjusting hole cover removed from the adjusting slot on the bottom of the brake backing plate

Brake shoes expanded until the pressure of the linings against the drum makes the wheel very difficult to turn

Starwheel rotated in the opposite direction until the wheel turns freely with a slight lining drag

Adjusting hole cover replaced and wheel lowered to the ground

Procedure repeated on all brakes
