SPECIFIC SAFETY PRECAUTIONS
1. Risk of Bursting
1.1 Serious injury or death may occur from an air tank explosion if the air tank is not
properly maintained or if modifications, alterations or repairs are attempted. Drain air
tank daily or after each use. Never drill into, weld, patch or modify the air tank. Replace
the tank immediately or replace the entire compressor, if a leakdevelops.
1.2 Serious injury or death may occur if modifications are made to the pressure switch,
safety relief valve or other components that control the tank pressure. Never make
adjustments to the components that control tank pressure. Do not make alterations to
the factory operating pressure settings. Check operation of the pressure relief valve on
a regular basis and never operate without a factory approved pressure relief valve.
1.3 Do not use plastic or pvc pipe for compressed air. Use only galvanized steel pipe and
fittings for compressed air distribution lines.
1.4 Check the manufacturer’s maximum pressure rating for air tools and accessories.
Compressor outlet pressure must be regulated so as to never exceed the maximum
pressure rating of the tool.
2. Risk of Explosion or Fire
Serious injury may occur if a fire is caused by overheating due to inadequate ventilation or
restrictions to any of the compressor’s ventilation openings. Never place objects against or
on top of an air compressor. Always operate air compressor at least 12 in. (30.5 cm) away
from any wall or obstruction. Always operate in a clean, dry and well-ventilatedarea.
3. Risk of Burn
Serious burn injuries could occur from touching exposed metal parts such as the compressor
head or motor during operation and even after the compressor is shut down for some time.
Never touch any of the exposed metal parts during operation and for an extended period of
time after the air compressor has shut down. Do not attempt maintenance on the unit until it
has been allowed to completely cool.

Contents:
• Air Compressor
BASIC AIR COMPRESSOR
COMPONENTS
The basic components of the air compressor are the electric
motor, thermal overload protection system (TOPS®), pump,
pressure switch and tank.
The electric motor (A) powers the pump.
TOPS®senses both temperature and current, providing better
motor overload protection than a magnetic starter, which senses
only current. TOPS®will automatically shutdown the compressor
when it senses an overload condition. Allow 10-15 minutes for the
unit to cool, then press the reset button on the motor to restart
the compressor.
The pump (B) compresses the air and discharges it into
the tank. The tank (C) stores the compressed air.
Fig.1

60 Gallon Single Stage Stationary Air Compressor
6For technical questions call 1-800-665-8685
8475006
V 1.6
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.
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.
MOTOR RESET SWITCH
WARNING! Ensure that all guards and shrouds are in place before pressing the reset switch to
restart the motor. Exposed components are hazardous and
could cause a serious injury to the user.
Once TOPS®shuts the compressor down, allow the pump to cool
for 10 to 15 minutes. Press the reset switch to restart the motor.
Take precautions before pressing the switch, as the motor and
pump may suddenly start without warning.
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. PRESSURE RELIEF VALVE
The air compressor is equipped with a safety-relief valve that is designed to discharge tank pressure
at a predetermined pressure setting. Check the pressure relief valve periodically by pulling on the
ring only when the tank pressure is completely drained.
The spring loaded valve should move freely within the pressure relief valve body. An inoperable
pressure relief valve could allow an excessive amount of tank pressure to build, causing the air tank
to catastrophically rupture or explode.
Do not tamper with or attempt to eliminate the safety reliefvalve.
C. 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.

Fig.3
ASSEMBLY
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 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 in. (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(A).
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 (see C).
4. Open the drain valve (E) by turning it anticlockwise.
5. Turn ON the main power disconnect switch. Turn the
pressure switch to the ON position (D). The motor should
start. Allow the compressor to run for 30 minutes, to break
in the internal parts. (Fig. 5)
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. Close the drain valve (F). Turn it clockwise.
8. Turn the pressure switch to the AUTO position (D). The
compressor will start and fill the tank to the cut-out
pressure and stop. As compressed air is used, the pressure
switch will restart the motor automatically.
PRE-START CHECKLIST
1. Always operate the compressor in a level position to allow
the tank to drain.
2. 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.
3. Check oil level daily and change at regular intervals.
4. 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.
5. 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.
1. Maintain the device with care. A device in good condition is ecient, easier to control and
will have fewer problems.
2. Follow the maintenance schedule for your compressor.
3. Drain tank of moisture after each day’s use. Leave the drain valve open until the next time it
is used. This will allow moisture to completely drain out and help prevent corrosion on the
inside of tank (Fig. 5).
4. Inspect the device fittings, alignment and hoses periodically. Have damaged or worn
components repaired or replaced by an authorized technician.
4.1 Pull the relief valve daily to ensure that it is operating properly and to clear the valve of
any possible obstructions.
4.2 Check that all connections are tight and don’t leak.

CHECKING THE OIL
Prior to daily operation, check the oil level in your compressor
pump. Check the sight glass to ensure the level is between A and
B. The optimal level is 2/3 full on the sight gauge. Do not operate
the pump with an inadequate or excessive amount of oil.
NOTE: Use synthetic, non-detergent air compressor oil.
CHANGING THE OIL
1. Remove the oil plug (F) and drain the oil until it slows to a drip, then close (Fig. 6).
2. Add oil to the pump by first removing the breather plug(G).
3. Add oil (approx. 40 oz/1.18 litres) until the level viewed through the sight glass is between
FULL (A) and ADD(B).
4. Replace the breather plug.
BELT-TIGHTENING DEVICE
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.
2. Loosen the motor mounting bolts.
3. Shift the motor to the point where the correct deflection exists.
4. Retighten the motor mounting bolts.
5. Check to ensure that the tension remained correct.
6. Reinstall the belt guard. All moving parts must be guarded.

8475006 V 1.6
PULLEY ALIGNMENT
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.
2. Loosen the motor mounting bolts.
3. Loosen the set screw on the motor pulley.
4. Align the motor pulley with the pump flywheel
(C = D = E).
5. Retighten the motor pulley set screw.
6. Adjust the proper belt tension.
7. Retighten the motor mounting bolts.
8. Reinstall the belt guard. All moving parts must
be guarded.
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 (H) and filter canister (I) to access the
filter (J).
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. Disconnect the power cord and coil it up on the handle. 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.
