Atlas Copco Portable Compressor XAS185JD7

Check Electrolyte level and terminals of battery

Check Leaks in air-, oil- or fuel system

Check Engine minimum and maximum speeds

Check and Adjust Brake system (if installed)

Warning: Always use a fiber brush. Never use a wire brush or metal objects.

Front cooler baffle removed by unscrewing 4 bolts?

Dirt removed from the coolers with a fiber brush?

When cleaning by air jet, blow air through the cooler in reverse direction of normal flow.

If the dirt is oily, wash the coolers with degreaser or a cleansing agent.

Protect the electrical and controlling equipment, air filters etc. against penetration of moisture.

Solvent applied to the fins using a spray gun?

Rinse the blocks by means of a water jet max. 100 psi at 2 inch distance after a soaking-in period. Steam cleaning may also be applied.

NOTE! The quality and the temperature of the oil determine the oil change interval

NOTE! The prescribed interval (See section 4.2) is based on an oil temperature of up to 100oC (212oF) and normal operating conditions

NOTE! When operating in high ambient temperatures, in very dusty or high humidity conditions, it is recommended to change the oil more frequently

Run the compressor until warm. Close the outlet valve(s) and stop the compressor. Wait until the pressure is released through the automatic blow-down valve. Unscrew the oil filler plug (FP) one turn. This uncovers a vent hole, which permits any pressure in the system to escape

Drain the oil by removing all drain plugs. Drain plugs are located at the oil tank, discharge manifold, and oil injection manifold. Catch the oil in a drain pan. Screw out the filler plug to speed up draining. Tighten the plugs after draining

Remove the oil filter (OFc), e.g. by means of a special tool. Catch the oil in a drain pan

Clean the filter seat on the manifold, taking care that no dirt drops into the system. Oil the gasket of the new filter element. Screw it into place until the gasket contacts its seat, then tighten one half turn only

Fill the air receiver until the pointer of the oil level gauge (OLG) registers in the upper extremity of the green range. Take care that no dirt drops into the system. Reinstall and tighten the filler plug

Run the unit at no load for a few minutes to circulate the oil and to evacuate the air trapped in the oil system

Unscrew the final filter element (1) from the adapter head

Clean the adapter head sealing surface. Lightly oil the gasket of the new element and screw the latter onto the header until the gasket is properly seated, then tighten with both hands

After replacing the final filter’s element, prime fuel system with manual prime button (FU) located below the fuel filter’s housing

Check for fuel leaks once the engine has been restarted

Sign off on the fuel filter change

1. Keep the battery clean and dry

- Keep the electrolyte level at 10 to 15 mm above the plates or at the indicated level; top up with distilled water only
