Tank Safety Valve (see B)
Used to allow tank pressure to escape into the atmosphere.
If the pressure switch does not shut off the compressor at it's "cut-
out" pressure setting, the safety valve will protect against high
pressure by releasing tank pressure at it's factory set pressure
(slightly higher than the pressure switch "cut-out" setting). To
operate manually, pull the ring on the valve to relieve air pressure
in the tank.
This air pressure regulator enables you to adjust line
pressure to the tool you are using.
,__ Never exceed the maximum working
pressure of the tool.
To adjust pressure setting, pull out the knob and turn
clockwise to increase pressure, and counterclockwise to
decrease pressure. To lock a pressure setting, push the knob in.
Regulated Pressure Gauge (see F)
This gauge measures the regulated line pressure.
Quick Connect(s) (see G)
A quick release for attaching and removing the air hose.
Pressure Release Valve (see C)
The pressure release valve (located on the bottom d the
pressure switch), is designed to release compressed air from the
compressor head and outlet tube when the compressor reaches
"cut-out" or is shut off. The pressure valve allows the motor to
restart freely. When the motor stops running, air wilt be heard
escaping from this valve for a few seconds. No air should be
heard leaking when the motor is running or after brief release
after reaching "cut-out" pressure.

Tank Pressure Gauge (see D)
This gauge measures the pressure level of the air stored
in the tank. It is not adjustable by the operator, and does not
indicate line pressure. B

MOTOR RESET SWITCH NOTE: To handle the initial electrical toad of starting the
'_ _Ensure that all guards and shrouds are in
place before pressing the reset switch to restart the
motor.
If the motor shuts down because of
overload, wait 10-15 minutes so the motor
can cool down, then press (NEVER force)
the reset switch (see H) to restart the
motor.
ELECTRICAL WIRING
Refer to the air compressor's serial label for the unit's voltage
and amperage requirements.
Use a dedicated circuit
For best performance and reliable starting, the air
compressor must be plugged into a dedicated circuit,
as close as possible to the fuse box or circuit breaker.
The compressor will use the full capacity of a typical 15 amp
household circuit. If any other electrical devices are drawing from
the compressor's circuit, the compressor may fail to start. Low
voltage or an overloaded circuit can result in sluggish starting that
causes the motor overload protection system or circuit breaker to
trip, especially in cold conditions.
air compressor, a circuit breaker is recommended. If the air
compressor is connected to a circuit protected by a fuse, use dual
element time delay fuses (Buss Fusetron type "T" only).
EXTENSION CORDS
NOTE: Avoid use d extension cords.
For optimum performance, plug the compressor power cord
directly into a grounded wall socket. Do not use an extension cord
unless absolutely necessary. Instead, use a longer air hose to
reach the area where the air is needed.
If use of an extension cord cannot be avoided, the cord
should be no longer than 50 feet and be a minimum wire size of
12 gauge (AWG). Do not use a 16 or 14 gauge extension cord.
Use only a 3-wire extension cord that has a 3-btade
grounding plug, and a 3-stot receptacle that will accept the
plug on the product. Make sure your extension cord is in good
condition. An undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. The smaller the gauge
number, the heavier the cord.
GROUNDING INSTRUCTIONS
This product should be grounded. In the event of an electrical
short circuit, grounding reduces the risk of electric shock by
providing an escape wire for the electric current.
