Campbell Hausfeld CE7002 Compressors Manual
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 the 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.
Notice
- Tanks rust from moisture build-up, which weakens the tank. Make sure to drain the tank regularly and inspect it periodically for unsafe conditions such as rust formation and corrosion.
- Fast-moving air will stir up dust and debris which may be harmful. Release air slowly when draining moisture or depressurizing the compressor system.
- STOP 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.
Spraying Precautions
Do not spray flammable materials in the vicinity of open flame or near ignition sources including the compressor unit.
- Do not smoke when spraying paint, insecticides, or other flammable substances.
- Use a face mask/respirator when spraying and spray in a well-ventilated area to prevent health and fire hazards.
- Do not direct paint or other sprayed material at the compressor. Locate the compressor as far away from the spraying area as possible to minimize overspray accumulation on the compressor.
- When spraying or cleaning with solvents or toxic chemicals, follow the instructions provided by the chemical manufacturer.
Getting To Know Your Compressor
Description
This oil-lubricated compressor is designed for do-it-yourselfers with a variety of home and automotive jobs. These compressors power spray guns, impact wrenches, and other tools. Compressed air from this unit will contain moisture. Install a water filter or air dryer if the application requires dry air.
Unpacking
After unpacking the unit, inspect carefully for any damage that may have occurred during transit. Make sure to tighten fittings, bolts, etc., before putting the unit into service. In case of questions, or damaged or missing parts, please call 1-800-543-6400 for customer assistance. Have the serial number, model number, and parts list (with missing parts circled) before calling.
Picking the Location
Do not locate the compressor air inlet near the steam, paint spray, sandblast areas, or any other source of contamination. The compressor should be installed on a foundation of sufficient strength and rigidity to support it without vibrating. It is recommended to use shims under the mounting feet to level the compressor, to prevent “rocking” and excessive vibration. To reduce vibration, isolator pads are recommended. When isolators are used, install a flexible coupling between the tank and any pipe permanently attached to the tank.
Installing A Shut-Off Valve
A shut-off valve should be installed on the discharge port of the tank to control the airflow out of the tank. The valve should be located between the tank and the piping system. As shown in Figure 3, assemble the outlet valve to the pipe nipple. Install assembled valve at either end of the tank. Use thread sealant tape on threads of pipe nipple to prevent air leaks.
Never install a shut-off valve between the compressor pump and the tank. Personal injury and/or equipment damage may occur. Never use reducers in the discharge piping. When creating a permanently installed system to distribute compressed air, find the total length of the system and select pipe size from the chart. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply air pressure to the piping installation and make sure all joints are free from leaks BEFORE underground lines are covered. Before putting the compressor into service, find and repair all leaks in the piping, fittings, and connections.
Piping
Never use plastic (PVC) pipes for compressed air. Serious injury or death could result. Any tube, pipe, or hose connected to the unit must be able to withstand the temperature generated and retain the pressure. All pressurized components of the air system must have a pressure rating of 200 psi or higher. Incorrect selection and installation of any tube, pipe, or hose could result in bursting and injury. Connect the piping system to the tank using the same size fitting as the discharge port.
Starter solenoid (unit with electric start only)
- Disconnect the negative cable from the battery terminal before attaching wires to the solenoid.
- Remove the 1/4-inch nut from the left stud. Do not make contact with the right stud to avoid possible engine ignition.
- Attach the positive (red) battery cable to the left stud and reinstall the 1/4-inch nut. Tighten the nut one full turn after it is finger-tight.
- Attach the negative (black) battery cable to a convenient ground. The best place is at the engine mounting bolt. Other secure places on the engine are suitable.
- Reattach the negative cable to the battery.
Operation
Getting Started
- Do not operate the compressor higher than the rated speed. Excessive engine speeds can damage the compressor and engine. Do not disconnect the battery from the engine ignition while the compressor is running (models w/electric start only).
- Check the oil level in the compressor and engine crankcase and add oil if required.
- Fill the fuel tank with clean, fresh, regular unleaded (or regular leaded if not available) grade automotive gasoline. Do not mix oil with gasoline.
- Before starting the compressor, put the toggle lever in Unload position. After the engine reaches full speed, flip the toggle lever to the Loaded position.
- When putting the unit into service for the first time, the compressor should be run continuously for one hour to allow proper seating of the piston rings.
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 at 20 psi under maximum pressure setting by opening the drain 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.
Continuous run operation
Continuous run operation is designed for gasoline engine units to ensure the required air pressure is always available and to eliminate the need for frequent starting. The engine and the pump continuously run to keep the air tank at maximum operating pressure.
Idle down / unloading
This unit is equipped with idle down/unloading control. To check operation:
- Close the outlet valve.
- Start the compressor and allow pressure to reach the proper limit of the control valve, which is set at 175 psi for 2 stage compressor. At this point, the compressor should unload through the breather bushing on the control valve and the engine should idle down.
- Open the outlet valve and allow the pressure in the tank to drop to the lower limit of the control valve which is preset at 145 psi. At this point, the control valve should close allowing the compressor to begin loading the tank instead of discharging through the breather bushing.
