GENERAL SAFETY RULES ■ Additional safety protection will be required in some environments. For example, the working area may Jk WARNING: include exposure to a noise level which can lead to hearing damage. The employer and user must ensure that any necessary hearing protection is provided and used by the operator and others in the work area. Some environments will require the use of head protec tion equipment.
GENERAL SAFETY RULES ■ ■ Never point any tool toward yourself or others. Keep the exterior of the air compressor dry, clean, and free from oil and grease. Always use a clean Disconnect power supply, open drain valve to decompress tank and allow water to drain, and allow air compressor to become cool to the touch before servicing. Turn pressure regulator knob fully cloth when cleaning. Never use brake fluids, gasoline, petroleum-based products, or any strong solvents to clean the unit.

ELECTRICAL EXTENSION CORDS SPEED AND WIRING Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the air compressor’s plug. When using the air compressor at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the compressor will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat.
GLOSSARY OF TERMS Air Filter Pressure Switch Porous element contained within a metal or plastic hous ing attached to the compressor cylinder head which removes impurity from the intake air ofthe compressor. Air Tank Automatically controls the on/off cycling of the compres sor. It stops the compressor when the cut-off pressure in the tank is reached and starts the compressor when the air pressure drops below the cut-in pressure. Cylindrical component which contains the compressed air.

FEATURES KNOW YOUR AIR COMPRESSOR PRESSURE REGULATOR KNOB See Figure 2. Use the pressure regulator knob to adjust the amount of air being delivered through the hose. Before attempting to use this product, familiarize yourself with all operating features and safety rules. REGULATOR PRESSURE GAUGE DESCRIPTION The current line pressure is displayed on the regulator pressure gauge. This pressure can be adjusted by rotating the pressure regulator knob.
ASSEMBLY ASSEMBLING THE RUBBER FOOT AND WHEELS See Figure 3. ■ ■ NUT S=WASHER(s) Mount the rubber feet as shown in figure. Tighten firmly with an open-end wrench (not included) to secure it in position. RUBBER ©^FOOT Mount the wheels as shown in figure. Tighten firmly with an open-end wrench (not included) to secure the wheels in position. I—WASHER li—SCREW WHEEL SCREW Fig. 3 ASSEMBLING THE HANDLE See Figures 4 - 5. ■ ■ HANDLE Lower the handle onto the compressor body, as shown in Figure 4.
ASSEMBLY PRESSURE SWITCH (ON/OFF) BREAKING IN THE PUMP See Figures 6 - 9. ■ ■ ■ ■ ■ ■ ■ Check and tighten all bolts, fittings, etc. Turn the pressure regulator knob fully clockwise to open the air flow. Place the lever of the pressure switch in ‘OFF’ position and plug in the power cord. Open the drain valve completely. Place the lever of the pressure switch in ‘AUTO’ position and run the air compressor for 10 minutes to break in pump parts. Place the lever of the pressure switch in ‘OFF’ position.
OPERATION dk WARNING: ¿k WARNING: Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict serious injury. Your tool may require more air consumption than this air compressor is capable of providing. Check the tool manual to avoid damage to the tool or risk of personal injury.
OPERATION DRAINING THE TANK See Figures 10 - 11. To help prevent tank corrosion and keep moisture out of the air used, the tank of the compressor should be drained daily. A correct use of the drain valve: ■ ■ ■ ■ ■ ■ Verify that the compressor is turned off. Holding the handle, tilt the compressor toward the drain valve so that it’s set in a lower position. Open the drain valve completely. Keep the compressor tilted (figure 11) until all moisture has been removed.
MAINTENANCE CHECK THE OIL LEVEL AT REGULAR INTERVALS A WARNING: See Figure 13. When servicing, use only identical Harbor Freight Tools replacement parts. Use of any other parts may create a hazard or cause product damage. oil level must be between the two marks MAX and MIN on Place the compressor on a level and straight surface. The the oil sight glass (fig. 13). Changing the oil: use SAE 40 oil (for cold climates, SAE 20 is recommended).
MAINTENANCE When the oil has drained out, re-fit the oil drain plug (fig. 13). Fill new oil through the oil filler opening until it comes up to the required level. Do not overfill. After topping up, tighten the oil fill plug (fig. 14), making sure that there are no leaks during use. Once a week, check the oil level to assure proper lubrication. SAFETY GUARD FOR THE V-BELT Fig. 15 RETENSIONING THE V-BELT See Figures 15 - 17.
MAINTENANCE CLEANING THE INTAKE FILTER See Figure 19. The intake filter prevents dust and dirt being drawn in. It is essential to clean this filter after at least every 100 hours in service. A clogged intake filter will decrease the compressor’s performance dramatically. Undo the two allen screws. You can then remove the filter from the two halves of the plastic housing, tap it to remove the dirt, blast it down with low-pressure compressed air (approx. 3 bar) and re-insert it.
TROUBLESHOOTING Problem Compressor will not run Motor hums but cannot run or runs slowly Fuses blow/circuit breaker trips repeatedly Thermal overload protector cuts out repeatedly Air receiver pressure drops when compressor shuts off Solution Possible Cause Loss of power or overheating Check for proper use of extension cord No electrical power Check to be sure unit is plugged in Check fuse/breaker or motor over load Blown shop/house fuse Replace shop/house blown fuse Shop/house breaker open Re
TROUBLESHOOTING Problem Solution Possible Cause Air leak from the valve of the pressure Check valve does not perform its Unscrew the hex-shaped head of the switch function correctly due to wear or dirt on check valve, clean the housing and the the seal special rubber disk (replace if worn).
