MAINTENANCE

To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications will depend upon the hours of operation and the working environment. Compressor outfits in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks.

Risk of Unsafe Operation. Unit cycles automatically when power is on. When servicing, you may be exposed to

voltage sources, compressed air, or moving parts. Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pressure, and allow the air compressor to cool.

NOTE: See “Operation” section for the location of controls.

To Check Safety Valve

Risk of Bursting. If the safety valve does not work properly, over pressurization may occur, causing air tank

rupture or an explosion.

1.Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve.

To Drain Tank

1.Set the On/Auto/Off lever to “OFF” and unplug unit.

2.		Risk of Flying Objects. Pull the regulator knob out and
		turn counter-clockwise to set the outlet pressure to
	zero when removing hose or accessories to prevent hose backlash.

3.Remove the air tool or accessory.

4.Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring.
