FEATURES KNOW YOUR AIR COMPRESSOR SAFETY VALVES See Figure 1. Before attempting to use this product, familiarize yourself with all operating features and safety rules. Safety valves aid in preventing system failures by relieving system pressure when compressed air reaches a pre-determined pressure level. All air receivers must be equipped with an adequately sized safety valve. This type of valve is preset by the manufacturer and must not be modified in any way.
FEATURES PRESSURE VESSELS When using the compressor for spray painting, isolate the compressor as far away from the work area as practical, employing extra air hose rather than an extension cord. Warranty will be void if a failure is determined to be caused by dust, dirt or other contaminants. Air receiver tanks and other pressure containing vessels must be equipped with a properly sized pressure relief valve, pressure gauge, and a tank drain.
ASSEMBLY is responsible for providing a suitable foundation & rubber foot mounting where necessary. DANGER! Under no circumstances should a compressor be used in an area where toxic, volatile, or corrosive agents are used or stored near the compressor. HIGH ALTITUDE APPLICATIONS Refer to the engine manufacturer’s recommendations for operation of engines at high altitudes. CAUTION! Unusual noise or vibration indicates a problem.
OPERATION DRAINING THE TANK See Figure 3. The drain valve is located on the underside of each air tank(s). The compressor can be tilted in the direction of the drain valve in order to allow removal of tank moisture. To help prevent tank(s) corrosion and keep moisture out of the air used, the tank(s) of the compressor should be drained daily. DRAIN VALVE DRAIN VALVE WARNING! Do not open a drain valve on any air tank containing more than 30 PSI of air pressure! (Rotate drain valve right to open) Fig.
OPERATION Drain moisture from the air tank(s). Never attempt to drain the tank(s) without first relieving the system pressure (using the instruction found in Draining the Tank). 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. STARTING & STOPPING THE COMPRESSOR Connect the air line to the quick coupler. Rotate regulator knob fully counterclockwise in order to close the air flow.
OPERATION TANK PRESSURE GAUGE WARNING: 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. Following all safety precautions in this manual and the manufacturer’s instructions in the air tool manual, you may now proceed to use your air-powered tool. If using an inflation accessory, control the amount of air flow with the pressure regulator knob.
MAINTENANCE MAINTENANCE SCHEDULE WARNING: Refer to the gas engine owner’s manual for maintenance procedures to be performed on the engine. If the unit is used in an excessively dirty or dusty environment, check and perform all maintenance procedures more often. When servicing, use only identical Harbor Freight Tools replacement parts. Use of any other parts may create a hazard or cause product damage.
MAINTENANCE Yearly Inspect the tank yearly for rust, pin holes, or other imperfections that could cause it to become unsafe. Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. OIL DRAIN PLUG LUBRICATION OIL SIGHT GLASS See Figure 6. Before starting this compressor, check the lubricant level.
MAINTENANCE BELT ALIGNMENT & ADJUSTMENT See Figures 7 - 8 - 9 - 10. Drive belts tend to stretch with normal use and require adjustment periodically (check monthly).
