This Air Compressor becomes extremely hot during operation. Do not touch any part of the Air Compressor during operation other than the Switch (34). Note: If the Air Compressor becomes too hot, it will activate an automatic thermal protector, shutting down the unit. If that happens, switch the power off and wait until the unit becomes cool (at least 15 minutes) to restart it. Note: We strongly recommend keeping your vehicles engine running during operation so as not to deplete your vehicle battery. Only operate your vehicle s engine in a well-ventilated area. Your vehicle produces carbon monoxide, an odorless, colorless gas, during operation; carbon monoxide inhalation can result in serious illness or death. Warning!! Only operate the Air Compressor on a level, stable platform. Do not place The Air Compressor on sandy or dusty ground. 1. Warning!! Make sure the Switch (34) is in the OFF position. 2. Attach the Red (+) Battery Clamp to the Positive (+) terminal of your 12 volt battery. 3. Attach the Black ( ) Battery Clamp to the Negative ( ) terminal of your 12 volt battery. 4. Start the vehicle s engine and keep it running throughout the process. See carbon monoxide warning above. 5. Attach the Quick Coupler to the Air Compressor. See FIGURE 1 below. FIGURE 1 Quick Coupler Page 4
Operation (continued) Note: If the Air Compressor becomes too hot, it will activate an automatic thermal protector, shutting down the unit. If that happens, switch the power off and wait until the unit becomes cool (at least 15 minutes) to restart it. 6. Thread the Brass Connector to the tire valve stem. See FIGURE 2 below. FIGURE 2 FIGURE 3. For Various Inflatables Brass Connector For Sporting Balls To fill sporting balls or other inflatables (i.e. rafts), use the three tips shown above in FIGURE 3. Simply attach the desired tip to the Brass Connector (See FIGURE 2) 7. Turn the Switch (34) to ON to begin inflation. Note: You may experience a slight delay for the compressor motor to start back up when the unit is pressurized. This is normal. 8. Fill to the item manufacturer s recommended pressure. Risk of Explosion! Never exceed 150 PSI or the working pressure of the item being inflated, whichever is less. 9. Monitor the inflation progress with the inline gauge. Turn the Switch (34) to OFF when the tire is full. To get the most accurate measurement, momentarily stop inflating. 10. Disconnect the Brass Connector as shown in FIGURE 2. 11. Disconnect the Red (+) Battery Clamp from the Positive (+) terminal of your 12 volt battery. 12. Disconnect the Black ( ) Battery Clamp from the Negative ( ) terminal of your 12 volt battery. Page 5
Maintenance Warning!! Never attempt any maintenance procedures when the unit is connected to a 12 Volt power source. Give the Air Compressor ample time to cool before touching the unit. 1. Before each use, make sure the Air Filter (14) is clean and clear of dust and debris. Snap of the cover of the Air Filter (14) and visually inspect the Air Filter (14). If it is minimally dirty, blow it off with a gentle burst of air. If it is too dirty to clean with a gentle burst of air, replace the filter. Clogged air filters greatly reduce performance and increase stress on the compressor. 2. Do not try to lubricate your Air Compressor. It comes with a permanently lubricated, maintenance free motor. 3. If the unit stops working and won t restart after it cools, check the fuse. If the 30 Amp fuse on the Battery Clamp power lines blows out, simply snap off the lid of the fuse holder, remove the fuse, and replace it. Snap the lid back on. See FIGURE 4.
