CALIFORNIA PROPOSITION 65
This product or
its power cord may
contain chemicals, including lead, known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
You can
create
dust when you cut, sand, drill or grind materials such as wood, paint, metal, concrete, cement, or other masonry. This dust often contains chemicals known to cause cancer, birth defects, or other reproductive harm. Wear protective gear.
GENERAL SAFETY INFORMATION
Air compressors are utilized in a variety of air system applications. Because air compressors and other components (material pump, spray gun, filters, lubrications, hoses, etc.) used make up a high pressure pumping system, the following safety precautions should be observed at all times. Only persons well acquainted with these rules of safe operation should be allowed to use the air compressor.
All electrical work
should be done
by a qualified (licensed or certified) electrician. On a properly wired circuit, the black wires supply a voltage potential even when the unit is off.
1. Read instruction manuals for each component carefully, before attempting to assemble, disassemble or operate your particular system.
2. Wear safety glasses and use hearing protection when operating the pump or unit.
3. Do not stand on or use the pump or unit as a handhold.
4. Do not exceed pressure rating of any component in system.
5. Protect material lines and air lines from damage or puncture. Keep hose and power cable away from sharp objects, chemical spills, oil, solvents, and wet floors.
6. Never point a spray gun at oneself or any other person. Accidental discharge may result in serious injury.
7. Check hoses for weak or worn condition, before each use, making certain all connections are secure; do not use if deficiency is found. Notify an authorized service facility for examination or repair.
Do not run
unattended. Leaving compressor in ON position may allow it to turn on inadvertently. To prevent this and possible damage from power surge, turn to OFF position after each use.
8. Release all pressures within system
slowly; dust and debris may be harmful.
Keep
fingers away from a running compressor; fast moving and hot parts will cause injury and/or burns.
Disconnect power
and depressurize system before servicing air compressor!
9. Follow all local electrical and safety
codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
10. Wiring and fuses should follow
electrical codes, current capacity, and be properly grounded.
11. Electric motors must be securely and
adequately grounded. See grounding instructions and extension cord information, in this manual.
12. Always disconnect power source
before working on or near a motor, or its connected load. If power disconnect point is out-of-sight, lock it in the open position and tag to prevent unexpected application of power.
13. Guard all moving parts; keep
visitors away. Never allow children in work area.
14. Use only a properly grounded
outlet that will accept a three pronged plug, and wear shoes to prevent shock hazards.
Be
careful when touching exterior of operating motor; it may be hot enough to cause injury. Compressor parts may be hot even if the unit is stopped.
15. Protect power cable from coming in
contact with sharp objects.
16. Clean electrical or electronic equipment with an approved cleaning agent, such as dry, nonflammable cleaning solvent.
Motors,
electrical equipment and controls can cause electrical arcs that will ignite a flammable gas or vapor. Never operate or repair the unit near a flammable gas or vapor. Never store flammable liquids or gases in the vicinity of the compressor.
17. To reduce fire hazard,
keep engine/motor exterior free of oil, solvent, or grease.
18. To avoid spontaneous combustion,
discard waste rags into approved metal waste cans.
19. NEVER reset safety valve or pressure
switch. Keep safety valve free from paint and other accumulations. This provides safety against over pressure.
Never remove or
attempt to adjust safety valve. Keep safety valve free from paint and other accumulations.
20. Do regular maintenance; keep all
nuts, bolts, and screws tight, to be sure equipment is in safe working condition .
21. Keep cleaning rags and other
flammable waste materials in a tightly closed metal container and dispose of later in the proper fashion.
22. Drain tanks of moisture after each
day’s use. If unit will not be used for a while, it is best to leave drain cock open until such time as it is to be used. This will allow moisture to completely drain out and help prevent corrosion of inside of tank.
23. Inspect tank yearly for rust, pin holes
or any other imperfections that could cause it to become unsafe. NEVER weld or drill holes in air 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 or damaged tanks.
Drain liquid from
tank daily.

Installation
LOCATION
It is extremely important to install the compressor in a clean, well ventilated area where the surrounding air temperature will not be more than 100°F.
A minimum clearance of 18 inches between the compressor and a wall is required because objects could obstruct air flow.
Do not locate the
compressor air inlet near steam, paint spray, sandblast areas or any other source of contamination. This debris will damage the motor.
Household use only. Store indoors. ELECTRICAL INSTALLATION
1. Check and tighten all bolts, fittings,
etc., before operating compressor.
2. Operate compressor in a ventilated
area so that compressor may be properly cooled.
3. Compressor should be located where
it can be directly plugged into an outlet, but if this is not possible, an extension cord may be used. It should be selected using the extension cord chart on page 3 as a guide.
4. To avoid loss of power and
overheating, it is better to use additional air hose instead of extension cords to reach work area.
WIRING
be in accordance with local codes and national electrical codes.
NOTE: 120 volt, compressor can be operated on a 120 volt, 15 amp circuit under the following conditions:
a. No other electrical appliances or
lights are connected to the same
branch circuit. b. Voltage supply is normal. c. Extension cords are of the
minimum gauge specified in this
instruction manual. d. Circuit is equipped with a 15 amp
circuit breaker or a 15 amp slow
blow fuse type T.
3. If above conditions cannot be met or if nuisance tripping of current protection device occurs, it may be necessary to operate compressor from a 120 volt, 20 amp circuit.
GROUNDING INSTRUCTIONS
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.
1. Local electrical wiring codes differ from area to area. Source wiring, plug and protector must be rated for at least the amperage

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 technician.
This product is for use on a nominal 120V circuit and has a grounding plug similar to the plug illustrated in Figure
2. Only connect the product to an outlet having the same configuration as the plug. Do not use an adapter with this product.
EXTENSION CORDS
To avoid loss of
power and overheating, it is better to use additional air hose instead of extension cords to reach work area.
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. An undersized cord results in a drop in line voltage and loss of power and overheating. [The table shows the correct size to use depending on cord length and nameplate ampere rating. When in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.]

Drain liquid from
tank daily.
Reduce tank pressure below 10 psi, then drain moisture from tank daily to avoid tank corrosion. Drain moisture from tank by opening the drain valve located underneath the tank.
Motor Protection - If the unit is over worked, a thermal limiter will shut unit off. If this happens, switch unit to OFF, wait 30 minutes to cool, turn ON again to resume work.
BEFORE FIRST START-UP BREAK-IN PROCEDURE
(Complete this procedure before using compressor for the first time. Once completed, it is not necessary to repeat.)
1. Turn regulator knob fully clockwise (to the right) to open air flow and open drain valve.
2. Turn On/Off switch to OFF position.
3. Plug in power cord.
4. Turn On/Off switch to ON position and run compressor for 30 minutes.
5. Turn On/Off switch to OFF position.
6. Unplug power cord.
The compressor is now ready for use.
OPERATING PROCEDURE
1. Turn regulator knob fully counter clockwise (to the left) to close air flow.
2. Connect air hose to outlet of regulator.
3. Turn On/Off switch to OFF position.
4. Plug in power cord.
5. Turn On/Off switch to ON position and let compressor run until it reaches automatic shutoff pressure.
6. Attach tire chuck or tool to end of hose.
7. Turn regulator knob clockwise (to the right) to desired pressure of tool being used.
ON/OFF CYCLING OF COMPRESSOR
In the ON 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 ON position and air is depleted from the tank by use of a tire chuck, tool,
HM7500 and HM7510
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.
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 pressure switch cannot function and the compressor will not operate. Make sure switch is in OFF position when connecting or disconnecting power cord from electrical outlet.
ASME SAFETY VALVE
Do not remove or
attempt to adjust
the safety valve!
Check the safety valve by performing the following steps:
1. Plug the compressor in and run until shut off pressure is reached (see Operating Procedure).
2. Wearing safety glasses, pull the ring on the safety valve (see Figure 4) to release pressure from compressor tank. Use your other hand to deflect fast-moving air from being directed toward your face.
Figure 4
3. The safety valve should automatically close at approximately 40-50 psi. If the safety valve does not allow air to be released when you pull on the ring, or if it does not close automatically, it MUST be replaced.
Safety valve must
be replaced if it cannot be actuated or it leaks air after ring is released.
PRESSURE GAUGES
Gauge attached to regulator indicates air pressure going to hose (and any tool attached to end of hose).
Gauge attached to pressure switch indicates air pressure in tank.
Maintenance
Release all pressure
and disconnect
power before making any repair.
1. Check compressor for any visible problems, especially check air filter to be sure it is clean.
2. Pull ring on safety valve and allow it to snap back to normal position (Figure 4).
Safety valve must
be replaced if it cannot be actuated or it leaks air after ring is released.
3. Daily with compressor shut off:
Depressurize system prior to draining tank. Drain moisture from tank by opening drain cock underneath end of tank and tilt to drain.
Drain Cock
