Warning: 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
