SPECIFIC SAFETY RULES Always follow all safety rules recommended by the manufacturer of your air tool, in addition to all safety rules for the air compressor. Following this rule will reduce the risk of serious personal injury. Know your power tool. Read operator’s manual carefully. Learn its applications and limitations, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire, or serious injury.
Do not adjust regulator to result in output pressure greater than marked maximum pressure of attachment. Do not use at pressure greater than the rated maximum pressure of this compressor.

SPEED AND WIRING The no-load speed of the electric motor varies by model and specification. The motor speed is not constant and decreases under a load or with lower voltage. For voltage, the wiring in a shop is as important as the motor’s horsepower rating. A line intended only for lights cannot properly carry a power tool motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to support two or three tools.

FEATURES KNOW YOUR AIR COMPRESSOR PRESSURE REGULATOR KNOB See Figure 2. Before attempting to use this product, familiarize yourself with all operating features and safety rules. Use the pressure regulator knob to adjust the amount of air being delivered through the hose. REGULATOR PRESSURE GAUGE OIL-FREE UNIVERSAL MOTOR The current line pressure is displayed on the regulator pressure gauge. This pressure can be adjusted by rotating the pressure regulator knob.
ASSEMBLY NUT WASHER ASSEMBLING THE RUBBER FOOT AND WHEELS See Figure 3. Mount the rubber foot as shown in figure. Tighten firmly with an open-end wrench (not included) to secure it in position. NUT Mount the wheels as shown in figure. Tighten firmly with an open-end wrench (not included) to secure the wheels in position. WHEEL WASHER RUBBER FOOT WASHER SCREW SCREW Fig. 3 FITTING THE AIR FILTER See Figures 4 - 5 - 6.
ASSEMBLY BREAKING IN THE PUMP QUICK COUPLER See Figures 7 - 8. REGULATOR PRESSURE GAUGE Check and tighten all bolts, fittings, etc. Turn the pressure regulator knob fully clockwise to open the air flow. Press the red button of the On/Off switch and plug in the power cord. Open the drain valve completely. Pull out the red button of the On/Off switch and run the air compressor for 10 minutes to break in pump parts. Press in the red button of the On/Off switch. Close the drain valve.
OPERATION WARNING: 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. WARNING: If using an inflation accessory, control the amount of air flow with the pressure regulator knob.
OPERATION DRAINING THE TANK See Figures 9 - 10. 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 10) until all moisture has been removed. Drain moisture from tank into a suitable container.
MAINTENANCE WARNING: WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemical can damage, weaken or destroy plastic which may result in serious personal injury. Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc.
