Breaking In The Pump - Craftsman 107.16574 Owner's Manual

the switch to the (OFF) position will remove power from the motor
and stop the air compressor.
Pressure regulator knob
Use the pressure regulator knob to adjust the amount of air being
delivered through the hose.
The air pressure coming from the air tank is controlled by the
regulator knob. Turn the pressure regulation knob clockwise to
increase discharge pressure, and counterclockwise to decrease
discharge pressure. Follow tool operating instructions for
recommended pressure range.
Regulator pressure gauge
The current line pressure is displayed on the regulator pressure
gauge. This pressure can be adjusted by rotating the pressure
regulator knob.
Safety valve
This valve is designed to prevent system failures by relieving
pressure from the system when the compressed air reaches a
predetermined level. The valve is preset by the manufacturer and
must not be modifi ed in any way. To verify the valve is working
properly, pull on the ring. Air pressure should escape. When the
ring is released, it will reset.
Tank pressure gauge
The tank pressure gauge indicates the pressure of the air in the
tank.
Drain valve
The drain valve is used to remove moisture from the air tank after
the air compressor is shut off.
Motor thermal overload protector
This air compressor is equipped with a thermal overload device
which will turn the air compressor off automatically, if the air
compressor becomes overheated. If the motor turns OFF
repeatedly, check for the following possible causes first: Low
Voltage from the outlet. Lack of proper ventilation or outside air
or room temperature too high. Extension cord too long or wrong
gauge wire used.
To reset the air compressor:
Turn the air compressor off.
Unplug the air compressor, and allow it to cool for 30 minutes.
Plug the air compressor into an approved outlet.
Turn the air compressor on.
Air fi lter intake
This fi lter is designed to clean air coming into the pump and
requires no maintenance when operated in accordance with the
warnings and operating instruction outlined in this manual. To
ensure the pump continually receives clean, cool, dry air do not
operate this compressor in dust fi lled atmosphere. Ventilation
openings must be kept free from obstructions.
