Important Safety Information (Continued)
BREATHABLE AIR WARNING
This compressor/pump is not equipped and should not be used “as is” to supply breathing quality
air. For any application of air for human consumption, the air compressor/pump will need to be
fitted with suitable in-line safety and alarm equipment. This additional equipment is necessary to
properly filter and purify the air to meet minimal specifications for Grade D breathing as described in
Compressed Gas Association Commodity Specification G 7.1, OSHA 29 CFR 1910. 134, and/or Canadian
Standards Associations (CSA).
DISCLAIMER OF WARRANTIES
In the event the compressor is used for the purpose of breathing air application and proper in-line
safety and alarm equipment is not simultaneously used, existing warranties shall be voided, and the
manufacturer disclaims any liability whatsoever for any loss, personal injury or damage.
General Safety
• Read all manuals included with this product carefully. Be thoroughly familiar with the controls and the
proper use of the equipment.
• Follow all local electrical and safety codes as well as the United States National Electrical Codes (NEC)
and Occupational Safety and Health Act (OSHA).
• Only persons well acquainted with these rules of safe operation should be allowed to use the
compressor.
• Keep visitors away and NEVER allow children in the work area.
• Wear safety glasses and use hearing protection when operating the unit.
• Do not stand on or use the unit as a handhold.
• Before each use, inspect compressed air system and electrical components for signs of damage,
deterioration, weakness or leakage. Repair or replace defective items before using.
• Check all fasteners at frequent intervals for proper tightness.
Motors, electrical equipment and controls can cause electrical arcs that will ignite a flammable
gas or vapor. Never operate or repair in or near a flammable gas or vapor. Never store
flammable liquids or gases in the vicinity of the compressor.
Never operate compressor without a beltguard. This unit can start automatically without
warning. Personal injury or property damage could occur from contact with moving parts.
• Do not wear loose clothing or jewelry that will get caught in the moving parts of the unit.
Compressor parts may be hot even if the unit is stopped.
• Keep fingers away from a running compressor; fast moving and hot parts will cause injury and/or burns.
• If the equipment should start to vibrate abnormally, STOP the engine/motor and check immediately for
the cause. Vibration is generally an indication of trouble.
• To reduce fire hazard, keep engine/motor exterior free of oil, solvent, or excessive grease.
An ASME code safety relief valve with a setting no higher than the Maximum Allowable
Working Pressure (MAWP) of the tank MUST be installed in the air lines or in the tank for
this compressor. The ASME safety valve must have sufficient flow and pressure ratings to protect the pressurized
components from bursting. The flow rating can be found in the parts manual. The safety valve in the intercooler does
not provide system protection.
Maximum operating pressure is 135 psi for single stage compressors. Do not operate with
pressure switch or pilot valves set higher than 135 psi (single stage).

INSTALLATION INSTRUCTIONS
Grounding
This product must 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. This product is equipped with a cord
having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet
that is properly installed and grounded in accordance with all local codes and ordinances. Do not use
grounding adapter.
Risk of electric shock. Improper use of grounding plug can result in a risk of electrical shock. Plug
must be plugged into an outlet that is properly installed and grounded in accordance with local
codes and ordinances by a qualified electrician.
This product comes from the factory ready for use on a nominal 120 volt circuit and has a grounding plug
similar to the plug illustrated in Figure 2. If the listed conditions cannot be met or if nuisance tripping of
the current protection device occurs, it may be possible to operate the compressor from a 120 volt 20 amp
circuit. See Figure 2.
Check motor data plate for 240 volt compatibility. A 240 volt unit must be operated on a 240 volt circuit.
The cord must only plug into a 240 volt grounded outlet and may require a new cord and plug. See Figure
3. This product may be modified to operate at 240V. To do so, a 240V power cord needs to be purchased
and installed on the unit and wired into the pressure switch just like the 120V cord. The panel on the back
of the motor needs to be opened and the flag terminals need to be moved so that the brown wire that is
on terminal #1 is on terminal #7 and the white wire that is on terminal #3 needs to be moved to terminal #1
(where the brown wire was originally). See Figure 4.
All wiring and electrical connections should be performed by a qualified electrician. Installation
must be in accordance with local codes and national electrical codes. If not properly grounded,
this tool can cause an electrical shock, particularly when used in damp locations, in proximity of plumbing, outdoors.
Installation of grounding plug can result in electric shock. When repair or replacement of the
cord or plug is required, do not connect the grounding wire to either flat blade terminal. The
wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire. Never
connect green (or green and yellow) wire to a live terminal.

INSTALLATION INSTRUCTIONS (CONTINUED)
Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that accepts the
plug on the product. Make sure your extension cord is not damaged. When using an extension cord, be sure
to use one heavy enough to carry the current your product draws. For lengths less than 25 ft. 16-3 AWG
extension cords shall be used. An undersized cord results in a drop in the voltage and loss of power and
overheating. (NOTICE: Table below shows the correct size to use depending on cord length. When in doubt,
use the next heavier gauge. The smaller the gauge number, the heavier the cord.)
Use of an extension cord may cause excess heat to motor. This could lead to tripped breaker (at electrical
panel) or tripped thermal overload (on compressor motor). If this occurs, eliminate extension cord and plug
compressor directly into electrical outlet. Avoid using extension cords; use longer air hose(s) instead.
Check with a qualified electrician or serviceman when the grounding instructions are not completely
understood, or when in doubt as to whether the product is properly grounded. Do not modify the plug
provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician. Only
connect the product to an outlet having the same configuration as the plug. Do not use an adapter with
this product.

INSTALLATION INSTRUCTIONS (CONTINUED)
Lubrication
Before operating compressor,
ensure oil is filled to the center of the
sight gauge (see figure 5).
Using any other type of oil may
shorten pump life and damage valves.
RECOMMENDED OIL (2 OPTIONS)
Single viscosity SAE30 ISO100 nondetergent
compressor oil. Part number ST125303AV (0.5 qt) or
ST126701AV (4 qt).
10W30 synthetic oil such as Mobile 1 or CE0032 (1 qt).
OIL CAPACITY
Approximately 8.5 oz.
Remove cap from oil fill opening. Install breather (found
in parts bag with this manual). Check oil level. See
specification label on compressor pump for the proper
oil capacity and oil type. All lubricated compressor
pumps discharge some condensed water and oil with
the compressed air. Install appropriate water/oil removal
equipment and controls as necessary for the intended
application.
Do not use regular automotive oil. Additives in regular
motor oil can cause valve deposits and reduce pump life.
For maximum pump life, drain and replace oil after the
first fifty (50) hours of operation. Then perform oil changes
every three (3) months.

OPERATING INSTRUCTIONS
All lubricated compressor pumps discharge some condensed water and oil with the compressed air. Install
appropriate water/oil removal equipment and controls as necessary for the intended application.
Failure to install appropriate water/oil removal equipment may result in damage to
machinery or workpiece.
Start-up/Break-in Procedure
Risk of Personal Injury. Do not attach air tools to open end of the hose until start-
up is completed and the unit checks okay.
Risk of Personal Injury. Never disconnect threaded joints with pressure in tank!
1. Check oil level per the Lubrication Section of
this manual.
2. Open the bottom tank drain valve (see Figure
6).
Turn outlet valve to open air flow.
3. Plug unit in.
4. Move pressure switch to the AUTO position to
run the unit (see Figure 7).
5. Run the unit for thirty (30) minutes at zero (0)
psi (under no load) to break in pump parts.
6. Move the pressure switch lever or knob to OFF
and turn tank drain valve to shut off air flow.
The compressor is now ready for use.
7. Change oil after first fifty (50) hours of
operation. Then perform oil changes every
three (3) months or two hundred (200) hours of
run time, whichever comes first.
Compressor Use
It is extremely important to operate the compressor
in a clean, well-ventilated area where the
surrounding air temperature will not be more than
100°F. Do not locate the compressor air inlet near
steam, paint spray, sandblast areas or any other
source of contamination.

OPERATING INSTRUCTIONS (CONTINUED)
On/Off Cycling of Compressor
Risk of Bursting. Drain tank every day to prevent corrosion and possible injury due
to tank damage. Do not operate drain with more than 40 psi in tank or drain valve may be
damaged. Drain tank of moisture daily using the drain valve in the bottom of the tank.
Unit care and maintenance. Drain liquid from tank daily.
In the AUTO position, the compressor pumps air into
the tank. When a shut-off (preset “cut-out”) pressure
is reached, the compressor automatically shuts off.
If the compressor is left in the AUTO position and air
is depleted from the tank by use of a tire chuck, tool,
etc., the compressor will restart automatically at its
preset “cut-in” pressure. When a tool is being used
continuously, the compressor will cycle on and off
automatically.
In the OFF position, the compressor will not operate.
Drain Tank. Disconnect, tag, unplug and lock out
power source; release pressure. Drain moisture from
tank by opening drain valve underneath tank (See
Figure 8).
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air compressor
pump. When humidity is high or when a compressor is in continuous use for an
extended period of time, this moisture will collect in the tank. When using a paint
spray or sandblast gun, this water will be carried from the tank through the hose, and
out of the gun as droplets mixed with the spray material.
IMPORTANT: This condensation will cause water spots in a paint job, especially when
spraying other than water based paints. If sandblasting, it will cause the sand to cake
and clog the gun, rendering it ineffective. A filter in the air line, located as near to the
gun as possible, will help eliminate this moisture.

MAINTENANCE / REPAIR
MAINTENANCE AND INSPECTION INSTRUCTIONS
Disconnect, tag and lock out power source then release all pressure from the system before
attempting to install, service, relocate or perform any maintenance.
In order to maintain efficient operation of the compressor system, check the air filter and oil level before
each use. The ASME safety valve should also be checked daily (see Figure 9). Pull ring on safety valve and
allow the ring to snap back to normal position. This valve automatically releases air if the tank pressure
exceeds the preset maximum. If air leaks after the ring has been released, or the valve is stuck and cannot
be actuated by the ring, the ASME safety valve must be replaced.
Do not tamper with the ASME safety valve.
Tank
Never attempt to repair or modify a tank! Welding, drilling or any other modification will
weaken the tank resulting in damage from rupture or explosion. Always replace worn, cracked
or damaged tanks.
Drain liquid from tank daily.
The tank should be carefully inspected at a minimum of once a year. Look for cracks forming near the
welds. If a crack is detected, remove pressure from tank immediately and replace.
Compressor Lubrication
See Installation. Add oil as required. The oil should be changed every three months or after every 200 hours
of operation; whichever comes first.
If the compressor is run under humid conditions for short periods of time, the humidity will condense in
the crankcase and cause the oil to look creamy. Oil contaminated by condensed water will not provide
adequate lubrication and must be changed immediately. Using contaminated oil will damage bearings,
pistons, cylinders and rings and is not covered under warranty. To avoid water condensation in the oil,
periodically run the compressor with tank pressure near 120 psi for single stage compressors by opening the
drain cock or an air valve connected to the tank or hose. Run the pump for an hour at a time at least once a
week or more often if the condensation reoccurs.
IMPORTANT: Change oil after first 50 hours of operation.
Air Filter
Never run the compressor pump without an intake air filter or
with a clogged intake air filter. The air filter element should be
checked monthly (see Figure 10). Operating compressor with
a dirty filter can cause high oil consumption and increase oil
contamination in the discharge air. If the air filter is dirty it must
be replaced.
Components
Turn off all power and clean the cylinder head, motor, fan blades,
air lines, aftercooler and tank on a monthly basis.

Belts
Lock out and tag the power then release all pressure from the tank to prevent
unexpected movement of the unit.
Check belt tension every 3 months. Adjust belt tension to allow 3/8 inch to 1/2 inch deflection with normal
thumb pressure. Also, align belts using a straight edge against the face of the flywheel and touching the
rim on both sides of the face. The belts should be parallel to this straight edge (see Figure 11). Dimension A
should be the same as B and C to ensure proper alignment of the belts.
Slots in the bed-plate allow for sliding the motor back and forth to adjust belt tension.
Removing Belt Guard
When removing belt guard front to
inspect or replace belts, inspect plastic retaining
clips and replace if damaged or if clip can be removed without a tool.
Removing Retaining Clips
1. Using crescent wrench on pliers, rotate clip 90°.
2. Pull clip out and away from beltguard.
3. Reverse process to reinstall after inspecting the clip.
