Checking Safety Valve, Draining Air Tank Fig

English

Checking Safety Valve

WARNING: Risk of bursting. If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture or an explosion.

WARNING: Risk from flying objects. Always wear certified safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields when using the compressor.

Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. NOTE: Ring may be difficult to pull when air tank pressure is at 0 PSI. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve.

Draining Air Tank (Fig. 1)

WARNING: Risk of unsafe operation. Risk from noise. Air tanks contain high pressure air. Keep face and other body parts away from outlet of drain. Use eye protection [ANSI Z87.1 (CAN/CSA Z94.3)] when draining as debris can be kicked up into face.

WARNING: Risk from noise. Use ear protection [ANSI S12.6 (S3.19)] as air flow noise is loud when draining.

NOTE: All compressed air systems generate condensate that accumulates in any drain point (e.g. tanks, filter, aftercoolers, dryers). This condensate contains lubricating oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations.

1.Ensure On/Auto/Off switch is in the OFF position.

2.Place a suitable container under the drain valve (H) to catch discharge.

3.Grasp lever on drain valve.

4.Slowly rotate lever to gradually bleed air from air tank.

WARNING: Risk of bursting. Drain air tank daily. Water will con- dense in air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture.

CAUTION: Risk of property damage. Drain water from air tank may contain oil and rust, which can cause stains.

5.When air tank pressure gauge reads 10 PSI, rotate valve to the fully open position.

6.Close drain valve when finished.

Checking Air Filter Element (Fig. 1)

WARNING: Hot surfaces. Risk of burn. Outlet tube, pump head, and surrounding parts are very hot, do not touch. Allow compressor to cool prior to servicing.

1.Ensure ON/OFF switch (A) is in the OFF Position.

2.Allow unit to cool.

3.Remove filter cover (J) from base.

4. Remove element from filter base.
