Draining The Tank; Checking The Safety Valve - Craftsman 107.16957 Operator's Manual

NOTE: Before connecting or disconnecting air tools, turn the
regulator knob counterclockwise to stop the flow of air.
Following all safety precautions in this manual and the
manufacturer's instructions in the air tool manual. You may
now use your air-powered tool.
If using an inflation accessory with a quick-connect fitting,
control the amount of air flow with the pressure regulator knob.
Turning the knob fully counterclockwise will completely stop
the flow of air.
NOTE: Always use the minimum amount of pressure
necessary for your application. Using a higher pressure than
needed will drain air from the tank more rapidly and cause the
unit to cycle on more frequently.
When finished, always drain the tank and unplug the unit.
Never leave the unit plugged in and/or running unattended.
WARNING
Check the air tool manual to insure the
correct air pressure regulator setting for optimum operation of
your air tools. If you are using an air tool not originally included
with the air tool kit supplied with this air compressor, your tool
may require more air consumption than this air compressor is
designed to supply.
Always read your air tool owner's manual to match the correct
air supply to your air tool to avoid damage to the tool or risk of
personal injury.
DRAINING THE TANK
See figure 10.
To help prevent tank corrosion and keep liquid and vapor
condensate out of the air supply, drain the compressor tank at
the end of each day's use.
To drain the tank:
Verify that the compressor is turned off.
Holding the compressor by its handle, tilt it in the direction of
the drain valve so that the valve is set in a lower position.
Open the drain valve by rotating it ¼ turn counterclockwise
(fig. 10).
Keep the unit tilted until all liquid and vapor condensate has
been drained into a suitable container.
NOTE: Condensate is a polluting material; dispose of it in
compliance with local regulations.
Close the drain valve by rotating it ¼ turn clockwise (fig. 10).

CHECKING THE SAFETY VALVE
See figure 11.
DANGER
Anything loosened from this device could fly up and hit you.
Failure to heed this warning could result in death or serious
personal injury.
The safety valve will automatically release air if the air receiver
pressure exceeds the preset maximum. The valve should be
checked before each day of use by pulling the ring by hand.
Turn the air compressor on and allow the tank to fill. The
compressor will shut off when the pressure reaches the preset
maximum.
Turn the air compressor off.
Pull the ring on the safety valve (fig. 11) to release air for
twenty seconds.
Safety
valve
Release the ring. Air will stop escaping when the ring is
released. Any continued loss of air after releasing the
safety valve ring indicates a problem with the safety valve.
Discontinue use and seek service before continued use of the
air compressor.

WARNING
or if the valve is stuck and cannot be actuated by the ring, do
not use the air compressor until the safety valve has been
replaced. Use of the air compressor in this condition could
result in serious personal injury.
