Lubricate axle bearings on wheel-mounted units

Proper lubrication of the portable compressor's bearing axle is critical to its proper function and reduction of wear on this part.

Use a wheel bearing grease that conforms to MILSPEC MIL-G-10924 or a high temperature one such as lithium complex NLGI consistency #2

Axles with the E-Z Lube feature can be periodically lubricated without removing the hubs from the axle.

Remove the rubber cap from the grease cap's end

Using a full charged grease gun, place the gun onto the grease zerk located on the end of the spindle. Make sure the nozzle is fully engaged on the fitting

Pump grease into the zerk. The old grease will be displaced and flow out of the cap around the grease gun nozzle

When the new grease starts flowing out of the cap, disengage the gun and wipe off any excess off the cap; and replace the rubber plug

Warning: Ensure the compressor is off and all internal pressure is relieved before starting the procedure

Run the compressor for five to ten minutes to warm the fluid

Shut the compressor down and relieve all internal pressure

Drain the fluid sump by removing the plug, or opening the valve at the bottom of the sump tank

Change the compressor fluid and replace the fluid filter element

Fill the sump with fluid in accordance with the specifications

Check the fuel filter for water

Drain water from the fuel/water separator

Place a container for collecting the fluid under the drain

Open the drain valve by turning it two turns to the left. Any water in the separator bowl will flow out through the drain

When the fluid flowing from the drain changes from water to fuel, close the drain valve by turning the valve to the right until tight

Replace the fuel filter of the fuel/water separator

Loosen and remove the air filter and cover

Remove the primary and optional secondary elements

Clean the body, inside and out, with a damp cloth

Reinstall (if clean) or replace the secondary element if installed

Replace the new primary filter element

Reposition the cover and lock it into the position

Reset the filter restriction indicator (if equipped)

Inspect air filter element for any light leaks indicating damage

Inspect all gaskets and gasket contact surfaces of the housing for any damage

Store clean elements for later use in a clean container

Inspect and tighten all air inlet connections before operating the compressor
