Oilless Compressors

Operation (Continued)

7.Attach chuck or other tool to open end of hose. Turn the regulator on.

In the ON position, the compressor pumps air into the tank. It shuts off automatically when unit reaches its maximum preset pressure. In the OFF position, the pressure switch cannot function and the compressor will not operate. Make sure switch is in OFF position when connecting or disconnecting power cord from electrical outlet.

ASME SAFETY VALVE

	! WARNING	attempt to adjust

the safety valve!

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 filter in the air line (MP3105), located as near to the gun as possible, will help eliminate this moisture.

	! CAUTION	If the thermal
		overload protector
	is actuated, the motor must be allowed
	to cool down before start-up is possible.
Figure 4	The motor will automatically restart
	without warning if left plugged into

	electrical outlet and unit is turned on.

Figure 3

This valve should be checked occasionally by pulling the ring by hand. Air may leak even after ring has been released. However, if the leaking continues for an extended period of time, or if the safety valve is stuck and cannot be activated by the ring, the safety valve MUST be replaced. (Note: Valve will reset when tank pressure reaches 40-50 PSI.)

REGULATOR KNOB

1.This knob controls air pressure to an air operated tool or paint spray gun.

2.Turn knob clockwise to increase air pressure.

3.To lower air pressure turn knob counterclockwise.

4.Turn fully counterclockwise to shut off flow of air completely.

! WARNING

Disconnect power source then release all pressure from the system before

attempting to install,

service, relocate or perform any maintenance.

Check compressor often for any visible problems and follow maintenance procedures each time compressor is used.

1.Pull ring on safety valve and allow it to snap back to normal position.

! WARNING	Safety valve must
	be replaced if it

cannot be actuated or it leaks air after ring is released.

2.Turn compressor off and release pressure from system. Drain moisture from tank by opening drain cock underneath tank. Tilt tank to remove all moisture.

3.Clean dust and dirt from motor, tank, air lines and pump cooling fins while compressor is still OFF.

LUBRICATION

This is an oilless type compressor requiring no lubrication.

THERMAL OVERLOAD PROTECTOR

This compressor is ! CAUTION equipped with an

automatic reset thermal overload protector which will shut off motor if it becomes overheated.

If thermal overload protector shuts motor OFF frequently, look for the following causes.

1.Low voltage.

2.Clogged air filter.

3.Lack of proper ventilation.

STORAGE

1.When not in use, store hose and compressor in a cool dry place.

2.Drain tank of moisture.

3.Disconnect hose and hang open ends down to allow any moisture to drain.
