2. SAFETY GUIDELINES
DEFINITIONS
Safety symbols identify important safety messages that alert to the possibility of personal injury or death.
Review them carefully before operating the unit and before performing maintenance or repairs. Check the rules
and regulations at your location and identify possible hazards. The appropriate signal word for each message
has been selected using the following guidelines:
- Danger indicates an immediate and specific hazard, which will result in severe personal
injury or death if the proper precautions are not taken.
- Warning indicates a specific hazard or unsafe practice, which could result in severe
personal injury or death if proper precautions are not taken.
- Caution indicates a potentially hazardous situation, which may result in minor or moderate
injury if proper practices are not taken.
____________________________________________________________________________
IMPORTANT SAFETY INSTRUCTIONS
Read and understand the operator’s manual and all safety alerts before
operating or maintaining your Compressor. Be certain that everyone operating this
equipment is familiar with the recommended operating and maintenance procedures
and follows all the safety precautions. Never let children or untrained adults operate
the machine.
_______________________________________________________________________________
RISK OF FIRE OR EXPLOSION
Never spray flammable liquids in a confined area. It is normal for the motor and pressure switch to produce
sparks while operating. If sparks come into contact with vapors from gasoline or other flammable solvents,
they may ignite, causing a fire or an explosion. Always operate the compressor in a well-ventilated area as far
from spray area as possible.
RISK OF BURSTING
Air under pressure will cause injury, death or property damage. Do not exceed pressure rating. Safety relief
valve settings must not be changed, check regularly for proper operation. Do not weld, drill or modify
compressor tank; it can severely impair tank strength and cause extremely hazardous conditions. Any
adjustment by user will void the warranty.
RISK OF INJURY
Do not operate with belt guard removed. Wait for all moving parts to stop before removing belt guard for
compressor servicing. Belt guard must be fastened in place before starting the compressor.
RISK OF ELECTRICAL SHOCK
All electrical enclosures, cables, wiring and components must be installed and grounded in accordance with
national and local electrical code.
ALL WIRING MUST BE DONE BY A LICENSED ELECTRICIAN. Failure to comply could result
in personal injury or damaged components.

6
2. SAFETY GUIDELINES (cont’d)
RISK OF BURNS
High temperatures are generated by the operation of the compressor. Contact with hot surfaces, such as the
pump or discharge hose could result in a serious burn. Allow them to cool off before handling or servicing.
Keep children away from the compressor at all times.
RISK TO BREATHING
Toxic, volatile and corrosive vapors can cause personal injury. Provide adequate ventilation. Never directly
inhale compressed air produced by a compressor. It is not suitable for breathing purposes. Read all labels
when you are spraying paints or toxic chemicals and follow the safety instructions.
RISK OF HEARING AND EYE INJURY
Always wear hearing protection and approved safety goggles when using an air compressor. Failure to do so
may result in hearing loss and serious injury.

3. OPERATION
3.1 HOW THE COMPRESSOR WORKS
3.1.1 COMPONENTS
The basic components of the air compressor are the electric motor, pump, tank and pressure switch. The
motor (item A) powers the pump. The motor drives a pulley and belt, which transfers power from the motor to
the pump pistons via a flywheel and a crankshaft. The flywheel fan helps cool the pump.
The pump (item B) compresses the air and discharges it into the tank. As the piston in the pump cylinder
moves downward, air enters the cylinder through the filter and air intake valves at atmospheric pressure. As
the piston moves upward, it compresses the air and discharges it into the tank through an unloader/check
valve.
The tank (item C) stores the compressed air. A check valve at the tank inlet prevents the compressed air in
the tank from flowing back into the pump.
The pressure switch (item D) shuts down the motor when the air pressure in the tank reaches the kick-out
pressure. As compressed air is used and the pressure level in the tank drops to the kick-in pressure, the
pressure switch restarts the motor automatically, without warning, and the pump resumes compressing air.

3.1.2 CONTROLS
1. Check Valve
Check valves (item G in Figure 1, page 5) are designed to prevent backflow of air pressure in the
compressed air system (i.e. air flows freely in one direction only).
2. Pressure Relief Valves
The pressure relief valve (item E in Figure 1, page 5) aids in preventing system failures by relieving
pressure when compressed air reaches a determined level. They are available in various pressure
settings. Pressure relief valves are pre-set by the manufacturer and under no circumstances should
the setting be changed by anyone other than the manufacturer. All pressure relief valves must be
tested on a regular basis and kept clean by pulling the ring connector on the end of the valve.
3. Pressure Switch
The pressure switch detects the demand for compressed air and allows the motor to start. When the
system pressure reaches a set limit, the motor is shut off. Pressure switches provided, are pre-set at
the factory and should not be adjusted. WARNING! Never exceed the designed pressure for the
system or overload the motor beyond the amperage rating on the motor label.
3.1.3 INLET AIR SYSTEM
A clean, cool and dry air supply is essential to the satisfactory operation of your compressor. The standard air
filter that the compressor is equipped with when leaving the factory is of sufficient size and is designed to meet
normal conditions, when properly serviced in accordance with the maintenance section of this manual.
If however the compressor is to be installed in a location where considerable dust, dirt and other contaminants
are prevalent, consult your local Distributor for advice. It is the user’s responsibility to provide adequate
filtration for these conditions. Oil bath filters are not to be used.
CAUTION: Never locate the compressor where toxic, volatile or corrosive vapors, air temperatures
exceeding 100 degrees F, water, or extremely dirty air could be ingested. The performance of the
compressor system could be adversely affected.

9
3.1.4 DISCHARGE SYSTEM
1. Discharge Pipe
The discharge piping should be of the same diameter as the compressor discharge connection, or
sized so that the pressure drop at any point in the system does not exceed 10% of the air receiver
pressure.
2. Auxiliary Air Receiver
Install auxiliary air receivers near heavy loads or at the far end of a long system. This will ensure
sufficient pressures if the use is intermittent, or sudden large demands are placed on the system.
3. Moisture Removal and Air Filtration
As the air cools, moisture will condense in the line. This moisture must be removed before it reaches
the tool being used. To remove this moisture, run the main air line downhill to a moisture trap and
drain. All service line outlets should be installed above the moisture trap to prevent moisture from
entering the tool or device used with the air.
4. Shut-off Valves
Install shut-off valves in each drop line to isolate the tool and its accessories for servicing. You can
also install a bypass line around an accessory.
5. Air Receiver Tank
An air receiver tank stores the compressed air. WARNING! Pressure vessels must not be
modified, welded, repaired, reworked or subjected to operating conditions outside the
nameplate ratings. Such actions may cause property damage, severe injury or even death.
6. Drain Valve
A drain valve must be located in the bottom of the air receiver tank to allow for moisture drainage.
7. Air Pressure Gauge
The air pressure gauge on the tank measures air pressure inside the tank. Install the air pressure
gauge in the drop line for each tool to regulate air pressure to the tool. Never exceed the maximum
pressure rating.
8. Air Lubrication
Install an air lubricator only for those tools requiring lubrication. DO NOT use a lubricator for paint
spraying or similar applications.

3.2 ASSEMBLY
1. Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged in transit
complete a damage claim.
2. Check the compressor’s item number to confirm you have received the model ordered.
3. Ensure that adequate lifting equipment is available for moving the compressor. Follow good shop
practices and safety procedures.
4. If necessary for your model install rubber feet provided in the kit.
CAUTION! The shipping pallet is not designed as a base for an operating compressor. Remove
the compressor from the pallet and place it on the floor or a hard, level surface. The compressor must
be level to ensure proper lubrication of the pump and good drainage of the moisture in the tank. We
recommend the use of rubber vibration pads under the feet for stationary units.
5. The flywheel side of the compressor must be at least 12 inches (31cm) from any wall or obstruction in
a clean, well-ventilated area to ensure sufficient air flow and cooling.
6. Connect discharge system components (not included) to the tank outlet.
7. IMPORTANT! All wiring information is stated on the electric motor and on the pressure switch, or
provided with the magnetic starter (sold separately). Princess Auto cannot, by law, provide the
customer with any additional wiring information.
3.3 PRE-OPERATION CHECKLIST
1. Remove all loose pieces and installation tools from the compressor and check for installation debris.
2. Unless otherwise specified, compressors are normally shipped without lubricant in the crankcase. Add
the correct amount of specified oil to the crankcase of the pump.
3. Check motor and compressor pulleys for alignment and tightness on shaft.
4. Manually rotate the compressor pulley several rotations to be sure there are no mechanical
interferences.
5. Check belt tension.
6. Check all pressure connections for tightness and leaks.
7. Make sure all pressure relief valves are correctly installed.
8. Be sure all guards are in place and securely mounted.
9. Check fuses, circuit breakers and thermal overloads for proper ratings.
10. Open all manual shutoff valves at and beyond the compressor discharge.
11. After all the above conditions have been satisfied, the unit can be connected to the proper power
source.
12. Jog the starter switch to check the rotational direction of the compressor. It should agree with the
rotation arrow embossed on the compressor pulley.

4. Manually activate safety relief valves by pulling ring or lever.
5. Run the compressor unloaded for 20 minutes to lubricate and break-in the internal parts.
6. Close the drain cock. Compressor will fill the tank to the cut out pressure.
7. Check the operation of controls and system pressure.
8. Observe compressor operation closely for the first hour and then frequently for the next 8 hours of
operation.
9. After the first 8 hours of operation change the oil, check the belt tension and inspect the system for leaks.
WARNING! - High temperatures are generated by the operation of the compressor. Contact with hot
surfaces, such as the pump or discharge hose could result in a serious burn. Allow them to cool off
before handling or servicing. Keep children away from the compressor at all times.
3.5 DAILY STARTING CHECKLIST

4. MAINTENANCE
4.1 MAINTENANCE SAFETY
1. Turn off motor and relieve pressure before servicing
2. Open all manual drain valves within the area to be serviced.
3. Isolate the compressor from the compressed air supply by closing a manual shutoff valve upstream
and downstream from the compressor. Display a sign in clear view at the shutoff valve stating that the
compressor is being serviced.
4. Lock open a pressure relief valve within the pressurized system to allow the system to be completely
de-pressurized. NEVER remove a plug to relieve the pressure!
5. Wait for the unit to cool before starting to service. Temperatures of 125F can burn skin. Some
surface temperatures exceed 350F when the compressor is operating.
4.2 SERVICING INTERVALS
1. Before and / or After Use
a) Check pump oil level.
b) Drain drop legs and traps in air distribution system.
c) Manually operate the pressure relief valves.
d) Give compressor an overall visual inspection and be sure safety guards are in place.
e) Check for any unusual noise or vibration
f) Check for oil leaks.
2. 50 Hours or Every Two-Weeks Service

14
4.3 PUMP LUBRICANT
1. Oil Level
Always operate the unit in a level position. Prior to start-up, check the sight glass to ensure the oil in
the pump is at the required level. If the oil level is too low, remove the oil fill plug and add oil until the
level is at the center of the sight glass. For approximate oil requirements, see pages 16-17. Do not
overfill or under fill as it could damage the pump. CAUTION! The oil level in the pump crankcase
must be checked daily.
2. Oil Type
The correct lubricant is essential to the proper operation of your compressor. For single stage or 2-
stage compressors, use ISO 68, SAE 25 weight oil. This compressor oil is available at your local
Princess Auto store. CAUTION! Do not use motor oil in the compressor pump.
3. Condensation
Water condensing in the crankcase can occur under certain humid conditions or light duty cycling.
This water must be removed from the pump to prevent damage. Drain the oil and refill.
Condensation can be prevented by allowing the pump to reach its normal operating temperature by
releasing air from the tank and allowing the pump to run, or by using more air, which will cause the
pump to operate more frequently. CAUTION! A rise in the oil level and a milky color indicates that
condensation is forming in the crankcase. This condensation must be drained immediately or the
pump may be damaged.
4.4 PULLEY ALIGNMENT & BELT TENSION
Improper pulley alignment and belt tension are causes for motor overloading, excessive vibration and
premature belt or bearing failure. To prevent this from happening, check the pulley alignment and belt tension
on a regular basis.
Periodically, inspect both the motor and compressor pulleys for oil, grease, nicks or burrs. Clean or replace
pulleys if necessary. Make sure the pulleys are securely fastened. Align the compressor pulley with motor.
The drive belt grooves of both pulleys should be in line with each other. The compressor crankshaft must be
parallel to the motor shaft.
WARNING! To avoid personal injury, always shut off main power disconnects for the compressor and
relieve all air pressure from the system before performing any service on the air compressor.
1. Belt Tension
Proper belt tension and pulley alignment must be maintained for maximum drive efficiency and belt
life. The correct tension exists if a deflection (see A in Figure 3 on the next page) of ½” (13 mm)
occurs by placing 10 lb (4.4 kg) of force (see B in Figure 3 on the next page) midway between the
motor pulley and the pump flywheel. This deflection can be adjusted by the following procedure. The
pulley should be carefully aligned with the flywheel and all setscrews should be kept tight.

15
4.4 PULLEY ALIGNMENT & BELT TENSION (cont’d)
1. Belt Tension (cont’d)
Figure 3: Belt Tension
a) Remove the belt guard.
b) Loosen the motor mounting bolts.
c) Shift the motor to the point where the correct deflection exists.
d) Retighten the motor mounting bolts.
e) Check to ensure that the tension remained correct.
f) Reinstall the belt guard. All moving parts must be guarded.
2. Pulley Alignment
To check pulley alignment, remove the belt guard and place a straightedge (C in Figure 4 below)
against the pump flywheel (D in Figure 4 below). Measure and record the distance from the
straightedge to the edge of the drive belt (dimension E). Then measure the distance from the
straightedge to the edge of the drive belt again as shown by dimensions F and G. Both distances
should be the same as dimension E. If F or G is different from E, there is a misalignment that must be
corrected before the compressor is run. To correct a pulley misalignment, use the following
procedure.
a) Remove the belt guard.
b) Loosen the motor mounting bolts.
c) Loosen the setscrew on the motor pulley.
d) Align the motor pulley with the pump flywheel (E=F=G).
e) Retighten the motor pulley setscrew.
f) Adjust the proper belt tension.
g) Retighten the motor mounting bolts.
h) Reinstall the belt guard. All moving parts must be guarded.

*NOTE – LOW VOLTAGE – Low voltage can cause a multitude of problems. The most common cause of low
voltage is when the wire size (gauge) supplying power to the compressor is too small. The longer the run of
wire, the larger the diameter must be to overcome the inherent voltage loss caused by the wire resistance.
The supply voltage at the main panel could also be low as supplied by your local power company, or you may
have too many other pieces of equipment running off the same line. Your local electrician should be contacted
to evaluate and correct the problem according to the National Electrical Code.
