Air Compressor
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.
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
When this manual refers to a part number, it refers to the included Parts List.
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, wire the air compressor into a dedicated 230V
circuit, as close as possible to the main electrical 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.
MAGNETIC STARTER
The air compressor requires a magnetic starter to prevent motor damage in the event of a
thermal overload.
LOW VOLTAGE PROBLEMS
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 230V 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. 3). 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 counterclockwise.
5. Turn ON the main power disconnect switch. Turn the pressure switch to the ON
position (B). The motor should start. Allow the compressor to run for 30 minutes,
to break in the internal parts. (Fig. 4)
NOTICE! Shut the compressor down immediately if the unit does not operate
properly after 30 minutes and contact Princess Auto Ltd. for a solution.
6. After about 30 minutes, shut o the main power disconnect.
7. Turn the pressure switch to o (A).
8. Close the drain valve (D). Turn it clockwise.
9. The compressor is ready for use.
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.

8475022V 1.3
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.
SHUTDOWN
1. Turn the pressure switch to the OFF position.
2. Turn the power disconnect switch to the OFF position.
3. Reduce pressure in the tank by slowly opening the drain valve at the bottom of the
tank. The escaping air will also blow condensation out. Leave the drain valve open
until the next use.
MAINTENANCE
WARNING! Only qualified service personnel should repair the device. An improperly
repaired device may present a hazard to the user and/or others.
CAUTION! Always unplug or shut down your compressor and drain the air tank
completely before attempting any type of maintenance. Wait for compressor to cool
before servicing.

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. 7). 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 and washers 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.
6. Reinstall the belt guard. All moving parts must be guarded.
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. 8). 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.

6. Replace hub by aligning non-threaded holes in hub to holes in sheave. Insert screws
and lock washers and tighten.
7. Adjust the proper belt tension.
8. Retighten the motor mounting bolts to 10.8 to 15 ft-lb (14.7 to 20.3 N-m).
9. Reinstall the belt guard. All moving parts must be guarded
DRIVE BELT REPLACEMENT
1. Remove the front of the belt guard by removing the screws and washers using a star
head screwdriver.
2. Loosen the motor mounting bolts.
3. Shift the motor towards the pump to the point where the belts can be easily removed
and installed.
4. Remove and replace belts. The belts must be centered over the grooves on the
flywheel and motor pulley.
5. Shift the motor back to the point where the correct deflection exists (see Drive Belt
Tension Adjustment).
6. Retighten the motor mounting bolts to 10.8 to 15 ft-lb (14.7 to 20.3 N-m).
7. Check to ensure that the tension remained correct.
8. Reinstall the belt guard. All moving parts must be guarded
TO REPLACE OR CLEAN A CHECK VALVE
1. Shut OFF the main power disconnect. Relieve all the air pressure from the tank
(refer to Shutdown in Operations). Make sure the compressor has cooled down
before servicing.
2. Using the appropriately sized wrench, loosen the compression nuts (A) on the check
valve (B) and pump head (C). Remove the transfer tube (D).
3. Using the appropriately sized wrench, loosen the compression nut (F) from the
connector (G), located on the side of the check valve. Remove the bleeder tube (E).
4. Making note of the orientation for reassembly, unscrew the check valve from the tank
(counterclockwise) using the appropriately sized wrench.
5. Using a pencil or screwdriver, carefully push the valve disc up and down (H). If the
valve disc does not move freely up and down, the check valve needs to be cleaned
or replaced.
6. Clean the check valve with warm soapy water and make sure to dry thoroughly
before reinstalling. If the disc valve still does not move freely up and down, it will
need to be replaced.
7. Apply thread sealant to the check valve threads and reinstall into the tank by turning

9. Replace the transfer tube and tighten compression nuts.
10. Perform the Break-In The Pump procedure in Operations to make sure there are no
leaks and the check valve is working properly.
CLEANING THE AIR FILTER
A dirty air filter will reduce the compressors 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.
Fig. 11
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.
