TIPS FOR LONGER BATTERY LIFE - Charge the battery for 14 hours before first using the compressor. Use the charging adapter provided. - Recharge within 48 hours of use. - Make sure battery is fully charged when storing. - Recharge every 3-5 months, even during periods of light or no use. - This product uses a sealed, rechargeable lead acid battery. The compressor has a small air reservoir and the pump is controlled by a pressure switch. When the internal pressure reaches approximately 100 psi, the pump will turn back on. 1. There is a 20 amp automotive type cartridge fuse inside the accessory storage cover. If the compressor fails to operate at all, check the fuse. 2. Internal safety valve will release if pressure exceeds 160 psi. This indicates a compressor problem. If this happens, do not operate compressor. Take it to an authorized Campbell Hausfeld Service Center. 3. There is a tank drain on the bottom of the compressor to remove moisture from the tank. Pressure should be be below 15 psi before opening drain valve. 4. Make sure that there are no leaks in the hose, attachments and fittings. If there are leaks, the pump will cycle as it replaces the lost air and will run the battery down. 3 Cordless Air Compressor Pre-Operation (Cont.) INDICATOR LIGHTS The indicator lights on the unit read as follows: Green. Fully charged and ready to run. Yellow. Partially discharged and operational. Red. Battery is low.
