Before Using the Air Compressor

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.

Since the air compressor and other components (pump, spray guns, filters, lubricators, hoses, etc.) used make up a high pressure pumping system, the following safety precautions must be observed at all times:

1. Read all manuals included with this product carefully. Be thoroughly familiar with the controls and the proper use of the equipment.

Follow all local safety codes as well

2. as the United States Occupational Safety and Health Act (OSHA).

3. Only persons well acquainted with these rules of safe operation should be allowed to use the compressor.

4. Keep visitors away and NEVER allow children in the work area.

Caution indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury.

Notice indicates important information, that if not followed, may cause damage to equipment.

5. Wear safety glasses (meeting ANSI Z87.1 or in Canada CSA Z94.3-99) and use hearing protection when operating the pump or unit. Everyday glasses are not safety glasses.

6. Do not stand on or use the pump or unit as a handhold.

7. Before each use, inspect compressed air system, fuel system and electrical components for signs of damage, deterioration, weakness or leakage. Repair or replace defective items before using.

8. Check all fasteners at frequent intervals for proper tightness.

Never operate compressor without a beltguard. Com-pressors can start automatically without warning. Personal injury or property damage could occur from contact with moving parts.

Do not wear loose clothing or jewelry

9. that will get caught in the moving parts of the unit.

Safety Instructions (continued)

Compressor parts may be hot even if the unit is stopped.

10. Keep fingers away from a running compressor; fast moving and hot parts will cause injury and/or burns.

11.If the equipment should start to vibrate abnormally, STOP the engine/motor and check immediately for the cause. Vibration is generally a warning of trouble.

NEVER refuel a running or hot engine. Explosive fuel can cause fires and severe burns. Avoid overfilling fuel tank.

12. Check fuel level before starting the engine. Do not fill the gas tank indoors. Wipe off any spilled gas before starting the engine.

Gasoline vapor is highly flammable. Refill outdoors or only in well ventilated areas. Do not store, spill or use gasoline near an open flame or heat devices such as a stove, furnace, or water heater, which utilize a pilot light, or any device that can create a spark. If gasoline is accidentally spilled, move unit away from the spill area and avoid creating any source of ignition until gasoline vapors have dissipated.

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.

Carbon monoxide can cause severe nausea, fainting or death. Do not operate unit inside a closed building or a poorly ventilated area.

13. To reduce fire hazard, keep engine/motor exterior free of oil, solvent, or excessive grease.

Never remove or attempt to adjust safety valve. Keep safety valve free from paint and other accumulations.

14. Do not tamper with governor setting on engine. Overspeeding the unit severely shortens engine life and may also be very hazardous.

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.

anks rust from moisture build-up,

15.T which weakens the tank. Make sure to drain tank daily and inspect periodically for unsafe conditions such as rust formation and corrosion

16. Fast moving air will stir up dust and debris which may be harmful. Release air slowly when draining moisture or depressurizing the compressor system.

Spraying Precautions

Do not spray flammable materials in vicinity of open flame or near ignition sources including the compressor unit.

19. Do not smoke when spraying paint,

insecticides, or other flammable substances.

20. Use a face mask/respirator when

spraying and spray in a well ventilated area to prevent health and fire hazards.

TOP the engine whenever leaving the

work area, before cleaning, making repairs or inspections. When cleaning, repairing or inspecting, make certain all moving parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent accidental starting.

18. Allow engine to cool before storing.

21. Do not direct paint or other sprayed material at the compressor. Locate compressor as far away from the spraying area as possible to minimize overspray accumulation on the compressor.

22. When spraying or cleaning with solvents or toxic chemicals, follow the instructions provided by the chemical manufacturer.

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 - 1966, 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 Campbell Hausfeld disclaims any liability whatsoever for any loss, personal injury or damage.

Glossary of Terms

ASME Safety Valve

A safety valve that automatically releases the air if the air receiver (tank) pressure exceeds the preset maximum.

PSI (Pounds per Square Inch)

Measurement of the pressure exerted by the force of the air. The actual psi output is measured by a pressure gauge on the compressor

SCFM (Standard Cubic Feet per Minute)

Sometimes called CFM (Cubic Feet per Minute). Measurement of air volume delivered by the compressor.

Air Delivery

A combination of psi and SCFM. The air delivery required by a tool is stated as (number) SCFM at (number) psi. The combination of these figures determines what size unit is needed.

Air Tank Capacity

The volume of air stored in the tank and available for immediate use. A large tank allows the intermittent use of an air tool with an air requirement higher than the compressor’s rated delivery.

Regulator

A control that adjusts the line pressure to the proper amount needed to operate spray guns and air tools.

Tank Pressure Gauge

Indicates tank pressure in psi.

Line Pressure Gauge

Displays the current line pressures. It is regulated by the regulator knob.

Cut-in/Cut-off Pressure

Specific psi at which a compressor starts and stops while refilling the air tank.

Unpacking and Checking Contents

1. Remove the air compressor from the carton.

2. Place the compressor on a secure, stationary work surface and look it over carefully.

Do not operate unit if damaged during shipping, handling or use. Damage may result in bursting and cause injury or property damage.

are 1/4” universal-style quick connect fittings and allow rapid tool changes.

Operating Your Air Compressor

Before starting the compressor, thoroughly read all component instruction manuals, especially the engine manual.

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.

Moisture in Compressed

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.

Air

Drain liquid from tank daily.

Do not attach air tools to open end of the hose until start-up is completed and unit checks OK.

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.

Lubrication

This compressor is shipped with oil.

Use single viscosity, ISO 100 (SAE 30), non-detergent compressor oil; or Mobil 1 5W30 or 10W30 synthetic oil may also be used. See illustration for proper oil fill.

Refer to engine manual for proper oil level and type.

Start-Up

To ensure proper operation, unit must be on a level surface.

1. Fill engine with oil and gasoline per

instructions furnished with engine.

2. Remove the compressor dipstick

breather or check oil sight glass to verify proper oil level.

3. Turn manual unloader lever up to a

horizontal position to allow the compressor pump to run without compressing air.

To Start Gasoline Engine

4. Move the choke lever to the CHOKE

position, turn the fuel lever ON, and turn the engine stop switch to the ON position.

5. Pull start grip lightly until resistance is

felt, and then pull briskly.

6. As the engine warms up, gradually

move the choke lever to the open position. See gas engine manual for more details.

7. Run the compressor unloaded for

approximately 30 minutes to break in the pump.

8. After approximately 30 minutes, move

the unloader lever down to the loaded position. The compressor will begin to

pump air into the tank. When maximum tank pressure is reached, the compressor automatically unloads, bringing the engine to idle. The engine remains at idle until tank pressure falls to a preset level. The engine then accelerates and the compressor pumps additional air into the tank.

Manual Unloader Lever in the Loaded Position

Maintenance

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 weekly (per maintenance schedule), oil level and gasoline level before each use. The ASME safety valve should also be checked weekly. 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.

With engine OFF, clean debris from engine, flywheel, tank, air lines and pump cooling fins.

Maintenance Schedule

Do not attempt to tamper with the ASME safety valve!

Check Oil Level l Drain Tank l Check Air Filter l Check Safety Valve l Blow Dirt From Unit l Check Belt Tightness l Change Oil l

Maintenance (continued)

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 tanks daily.

The tanks 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.

Tank Drain (2)

Filter Removal, Inspection and Replacement

To change a filter, pull off the filter housing cover. If filter element is dirty, replace element or entire filter.

Drive Belt

Belt stretch is a result of normal use. When properly adjusted, the belt deflects about 1/2” with five pounds of pressure applied midway between the engine pulley and pump.

To adjust drive belt tension:

1. Remove belt guard and loosen

engine brace.

2. Loosen the four fasteners holding the

engine to the baseplate.

3. Shift the engine in the proper direc-

tion. The belt must be properly aligned when adjustment is made.

4. To align belt, lay a straight edge

against the face of the flywheel, touching the rim at two places.

5. Adjust flywheel or engine pulley so

that the belt runs parallel to the straight edge.

6. Use a gear puller to move the pulley

on the shaft and tighten fasteners.

7. Adjust brace and reinstall belt guard.
