INSPECTION, MAINTENANCE, AND CLEANING

1.CAUTION! Always release all pressure from the system and disconnect all tools from the Air Compressor before performing any inspection, maintenance, or cleaning. Be aware that the sudden release of air from any valve or air tool can present a danger to one’s ears.

2.BEFORE EACH USE, inspect the general condition of the Air Compressor. Check all air fittings for leaks. Check for loose screws, misalignment or binding of moving parts, cracked or broken parts, damaged, and any other condition that may affect the safe operation of this tool. If abnormal noise or vibration occurs, immediately release all pressure from the system and have the problem corrected before further use. Do not use damaged equipment.

3.DAILY: EMPTY CONDENSATION FROM THE AIR TANKS (31).

The Drain Plugs are located underneath each Air Tank, and should be used daily to release all trapped moisture that may cause Air Tank corrosion. Slowly and carefully unscrew (no more than four threads) the Drain Plugs until the condensation begins to be released from the Air Tanks. Allow sufficient time for all of the condensation to escape from the Air Tanks. Then, firmly retighten the Drain Plugs. (See Figure E.)

4.DAILY: Check the Air Compressor oil level. If necessary, fill with a premium

quality, 30-weight, non-detergent, compressor oil. NOTE: When checking the Air Compressor oil level, make sure to unscrew (do not pull) the Oil Cap (23).

5.EVERY 100 HOURS OF USE: Clean the Air Filter (B4) with a mild solvent. Then, dry and reattach the Air Filter Sleeve. (Replace the Air Filter Sleeve if it is too dirty to properly clean.) To clean or replace the Air Filter Sleeve, remove the two Hex Socket Set Bolts. Remove the Air Filter Cover. Remove the Air Filter Sleeve and clean. Then, replace the Air Filter Sleeve and two Hex Socket Set Bolts.
