PART DESCRIPTION QTY.

A Pressure Switch - AUTO/OFF Switch - In the AUT O position, the compressor

shuts off automatically when tank pressure reaches the maximum preset pressure. After air is used from the tank and drops to a preset low level, the pressure switch automatically turns the motor back on. In the OFF position, the compressor will not operate. This switch should be in the OFF position when connecting or disconnecting the power from the unit.

When the pressure switch turns the motor off you will hear air leaking out of the pressure switch unloader valve for a short time. This releases the air pressure from the discharge tube and allows the compressor to restart easier.

B ASME Safety Valve - This valve automatically releases air if the tank pressure

exceeds the preset maximum.

C Discharge Tube - This tube carries compressed air from the pump to the check

valve. This tube becomes very hot during use. To avoid the risk of severe burns, never touch the discharge tube.

D Check Valve - One-way valve that allows air to enter the tank, but prevents air in the

tank from flowing back into the compressor pump. E Belt Guard - Covers the belt, motor pulley and flywheel. 1 F Tank Drain Valve - This valve is located on the bottom of the tank. Use this valve to

drain moisture from the tank daily to reduce the risk of corrosion.

G Tank Pressure Gauge - Indicates amount of air pressure stored in tank. 1 H Air Filter - Keeps large particulates out of the air flowing into the compressor. 1

I Breather - Vent for crankcase. 1

OPERATING INSTRUCTIONS

ON/OFF CYCLING OF COMPRESSOR

WARNING

Risk of Bursting. Drain tank every day to

prevent corrosion and possible injury due to tank damage. For optimal performance of tank drain, tank pressure should be between 10 40 PSI. Do not operate drain with more than 40 PSI in tank or drain valve may be damaged. Drain tank of moisture daily using the drain valve in the bottom of the tank.

In the AUTO position, the compressor pumps air into the tank. When a shut-off (preset “cut-out”) pressure is reached, the compressor automatically shuts off.

If the compressor is left in the AUTO position and air is depleted from the tank by use of a tire chuck, tool, etc., the compressor will restart automatically at its preset “cut-in” pressure. When a tool is being used continuously, the compressor will cycle on and off automatically.

Unit Care and Maintenance. Drain liquid from tank daily.

NOTICE

In the OFF position, the compressor will not operate.

CARE AND MAINTENANCE

WARNING

Risk of Explosion. Disconnect,

tag and lock out power source, then release all pressure from the system before attempting to install, service, relocate or perform any maintenance.

All repairs should be performed by an authorized service representative. For efficient operation, perform the following maintenance.

4. Drain Tank. Disconnect, tag and lock out power source; release pressure. Drain moisture from tank by opening drain valve underneath tank once tank pressure is less than 40 psi (See Figure 2).

5. Check air filter to be sure it is clean. Replace filter if filter is dirty.

MOISTURE IN COMPRESSED AIR

Moisture in compressed air will form into droplets as it comes from an air compressor pump. When humidity is high or when a compressor is in continuous use for an extended period of time, this moisture will collect in the tank. When using a paint spray or sandblast gun, this water will be carried from the tank through the hose, and out of the gun as droplets mixed with the spray material.

IMPORTANT: This condensation will cause water spots in a paint job, especially when spraying

other than water based paints. If sandblasting, it will cause the sand to cake and clog the gun, rendering it ineffective. A ﬁ lter in the air line, located as near to the gun as possible, will help eliminate this moisture.

CARE AND MAINTENANCE

6. Check the safety valve by performing the following steps: a. Restore power to unit; turn pressure switch to the

AUTO position. Run until unit reaches 90 PSI. Turn pressure switch to OFF position.

b. Wearing safety glasses and hearing protection,

pull the ring on the safety valve to release pressure from compressor tank. Protect yourself from fast-moving air being released; do not allow fast-moving air to be directed toward your face (See Figure 3).

c. The safety valve should automatically close at

approximately 40-50 PSI. If the safety valve does not allow air to be released when you pull on the ring, or if it does not close automatically, it MUST be replaced.

7. Check belt for signs of excessive wear. If belt shows signs of wear, replace it. Check belt for proper tension / alignment.
