V 3.4
BASIC AIR COMPRESSOR COMPONENTS
The basic components of the air compressor are the
electric motor, pump, pressure switch,
and tank.
The electric motor (A) powers the pump.
The pump (B) compresses the air and discharges it into
the tank. The tank (C) stores the compressed air.
The pressure switch (D) shuts down the motor and
relieves air pressure in the pump and transfer tube when
the air pressure in the tank reaches the cut–out pressure.
As compressed air is used and the pressure level in the
tank drops to the cut–in pressure, the pressure switch
restarts the motor automatically and the pump resumes
compressing air.
A magnetic starter (E) is required for the proper
operation of the compressor. A magnetic starter that is
not factory mounted on the compressor can be mounted
on the wall if desired. Mount as close to compressor
as possible. Size the wires, protect them with conduit and provide branch circuit protection per
electrical and safety codes, as well as the most recent Canadian Electrical Code (CE) and Canadian
Centre for Occupational Health and Safety (CCOHS).
COMPRESSOR CONTROLS
Main Power Disconnect
Install a main power disconnect switch in the power line to the compressor, near the compressor’s
location for ease of use and safety. The disconnect switch functions are selected manually. When
the switch is in the ON position, power is supplied to the compressor. The pressure switch will start
up or shut down the compressor automatically, based on air demand. Always select OFF when the
compressor is not being used. When turned OFF, the main power disconnect switch shuts o all
power to the compressor.
Magnetic Starter Reset Switch
WARNING! 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 an overload, wait 10–15 minutes so the motor can cool down,
then press (never force) the reset switch on front of the magnetic starter to restart the motor.
A. PRESSURE SWITCH
WARNING! The pressure switch is preset. Do not attempt to tamper or adjust the setting.
The pressure switch controls the level of air pressure in the tank by automatically starting and
stopping the motor, as required to maintain the factory preset pressure level. The pressure switch
also automatically bleeds pressure from the pump head when the pump stops. This feature
eliminates back pressure in the pump, ensuring easier starting.
Fig.1

Visit www.princessauto.com for more information
8475014 V 3.4
B. TANK SAFETY VALVE
The tank safety valve is designed to discharge
tank pressure at a predetermined setting,
slightly above the compressor’s cut-out pressure
setting. The safety valve will protect against high
pressure ruptures if the pressure switch does not
shut o the compressor. Do not tamper with or
attempt to eliminate the tank safety valve.
C. PRESSURE RELIEF VALVE
The air compressor is equipped with a pressure
relief valve (located on the bottom of the
pressure switch) that is designed to release
compressed air from the compressor head and
outlet tube when the compressor reaches the
cut-out pressure setting or is shut o. The
pressure valve allows the motor to restart freely.
When the motor stops running, air will be heard
escaping from this valve for a few seconds. No
air should be heard leaking when the motor is running or after a brief release of air after reaching
the cut-out pressure.
Do not tamper with or attempt to eliminate the safety relief valve.
D. TANK PRESSURE GAUGE
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.
ASSEMBLY
LOCATION INSTALLATION
Locate the compressor according to the
following guidelines:
1. For optimum performance, locate the
compressor close to the power panel (see
section Main Power Panel) and as close as
possible to the place where the air will be
used. This ensures maximum power to the
compressor and maximum air pressure to the
air tool. If both of these conditions cannot
be met, it is better to locate the compressor
close to the power panel and use a longer
hose to reach the usage area.
2. The flywheel side of the compressor must be
at least 12 inches (30.5 cm) from any wall or
obstruction, in a clean, well-ventilated area, to ensure sucient air flow and cooling.
3. In cold climates, locate the compressor in a heated building to reduce problems with
lubrication, motor starting and freezing of water condensation.
4. The compressor must be level to ensure proper lubrication of the pump and good drainage
of the moisture in the tank.
5. Vibration pads under the tank’s feet are recommended.

ELECTRICAL POWER REQUIREMENTS
WARNING! All wiring should be performed by a qualified electrician.
Refer to the air compressor’s serial label for the unit’s voltage and amperage requirements. Ensure
that all wiring is done by a licensed electrician in accordance with all electrical and safety codes,
as well as the most recent Canadian Electrical Code (CE) and Canadian Centre for Occupational
Health and Safety (CCOHS).
MAIN POWER PANEL
For best performance and reliable starting, the air compressor must be plugged or wired into
a dedicated 240V circuit, as close as possible to the main power panel. A circuit breaker is
recommended. Use a time delay fuse if the air compressor is connected to a circuit protected by a
fuse, as the compressor will momentarily draw several times its specific amperage when
first started.
MAIN POWER DISCONNECT SWITCH
Low voltage or an overloaded circuit can make it dicult to start the motor or can cause the
circuit breaker to trip, especially in cold conditions. Low voltage can have several sources:
Low supply voltage from the local power company.
Other equipment running on the same line. The compressor may fail to start if any other
electrical devices are drawing from the compressor’s circuit.
Inadequate wiring to the power source. The input voltage will drop by 20 to 40 volts at
startup if the wiring is not adequate. Inadequate wiring depends on the distance between
the compressor and the 240V power source. As distance increases without a change in wire
gauge (thickness), the power will drop and not enough Volts/Amps will reach the motor.
The wire gauge must increase in size (gauge 8 is larger than gauge 10) to accommodate the
voltage drop. Refer to the Canadian Electrical Code (CE) to determine proper wire size for
your circuit.
GROUNDING INSTRUCTIONS
This product must be connected to a permanent, metallic wiring system or a grounding terminal/
lead on the equipment.
OPERATION
BREAK-IN THE PUMP
NOTICE! The pump is shipped with break–in oil, which should be changed after the first 8 hours
of operation. To reduce maintenance and repair problems, use only a premium compressor oil.
1. Check the level of oil in the pump with the sight glass. The pump oil level must be between A
and B (Fig. 4). Do not overfill or underfill.
2. Make sure the power is connected at the power panel.
3. Turn the pressure switch to the OFF position (A).
4. Open the drain valve (C) by turning it clockwise.
5. Turn ON the main power disconnect switch. Turn the pressure switch to the AUTO position

PRE-START CHECKLIST
1. Inspect/clean/change intake elements on a regular basis. The ingestion of dirt into the pump
is the primary cause of premature wear. Check intake filters daily.
2. Check oil level daily and change at regular intervals.
3. Check the tension of bolts and hardware on a regular basis. Operation of any equipment with
loose bolts and/or fittings will lead to excessive vibration and the premature failure of the
compressor system control components.
4. Drain moisture from the air tank daily. Water is a natural byproduct of compressed air. Drain
the air tank after each use to avoid internal tank corrosion. Keep drain valves open when not
in use.
DAILY START UP
WARNING! High temperatures are generated by the electric motor and the pump. To prevent
burns or other injuries, DO NOT touch the compressor while it is running. Allow it to cool before
handling or servicing. Keep children away from the compressor at all times.
1. Check the sight glass to ensure the level of oil in the pump is at the required level.
2. Turn the main power disconnect switch to the OFF position.
3. Close the tank drain valve.
4. Turn ON the main power disconnect switch. Turn the pressure switch to the ON position. The
pump will start filling the tank with air. When the air pressure in the tank reaches the level
preset at the factory, the pressure switch will turn o the electric motor. As air is used and
the pressure level in the tank drops, the pressure switch will start the motor and the pump
will begin refilling the tank.

PULLEY ALIGNMENT
NOTICE! Once the motor pulley is moved from its factory set location, the grooves of the flywheel
and pulley must be aligned to within 1/16 in. to prevent excessive belt wear.
To check pulley alignment, remove the belt guard and place a straightedge (A) against the pump
flywheel (B) (Fig. 10). Measure and record the distance from the straightedge to the edge of the
drive belt at point C. Then measure the distance from the straightedge to the edge of the drive
belt again at points D and E. Both distances should be the same as at point C. If either D or E are
dierent from C, there is a misalignment which must be corrected before the compressor is run.
To correct a pulley misalignment, use the
following procedure.
1. Remove the belt guard with a star
head screwdriver.
2. Loosen the motor mounting bolts.
3. Remove the 2 screws and lock
washers from the hub using a 7/16
in. wrench.
4. Insert the screws into the threaded
holes on the hub and tighten to
pull hub away from sheave,
remove screws.
DRIVE BELT TENSION ADJUSTMENT
Drive belt tensioning and pulley alignment are
done at the same time. They are discussed
separately for clarity.
Proper belt tension and pulley alignment
must be maintained for maximum drive
eciency and belt life. The correct tension
exists if a deflection (A) of 1/2 in. (13 mm)
occurs by placing 10 lb (4.6kg) of force (B)
midway between the motor pulley and the
pump flywheel (Fig. 8). Thisdeflection can
be adjusted by the following procedure. The
pulley should be carefully aligned with the
flywheel and all set screws should be
kept tight.
1. Remove the belt guard by removing the
screws using a star head screwdriver.
2. Loosen the motor mounting bolts.
3. Shift the motor to the point where the correct
deflection exists (A and B).
4. Retighten the motor mounting bolts to 10.8 to
15 ft-lb (14.7 to 20.3 N-m).
5. Check to ensure that the tension
remained correct.

CLEANING THE AIR FILTER
A dirty air filter will reduce the compressor’s performance and
life. To avoid any internal contamination of the pump, the filter
should be cleaned frequently and replaced on a regular basis.
Remove the wing nut (A) and metal cover (B) to access the
filter element (C).
Felt filters should be cleaned in warm, soapy water, rinsed and
allowed to air dry before reinstallation. Paper filters should
be replaced when dirty. Do not allow the filter to become
filled with dirt or paint. Replace the filter if it becomes filled
withpaint.
TESTING FOR LEAKS
Check that all connections are tight. A small leak in any of
the hoses, transfer tubes or pipe connections will substantially reduce the performance of your
air compressor. Locate a leak by spraying a small amount of soapy water around the area of the
suspected leak. Repair or replace the faulty component if bubbles appear. Do not over tighten
any connections.
STORAGE
Before storing the compressor for a prolonged period, use an air blowgun to clean all dust and
debris from the compressor. Turn the power disconnect switch to the OFF position. Open the drain
valve to release all pressure from the tank. This will also drain all moisture from the tank. Clean
the filter element and filter housing; replace the element if necessary. Drain the oil from the pump
crankcase and replace it with new oil. Cover the entire unit to protect it from moisture
and dust.
DISPOSAL
Recycle a device damaged beyond repair at the appropriate facility.
Contact your local municipality for a list of disposal facilities or by-laws for electronic devices,
batteries, oil or other toxic liquids.
IMPORTANT! DO NOT pollute the environment by allowing uncontrolled discharge of waste oil.
