a s s i s t a n c e . TRANSPORTING When transporting the compressor in a vehicle, trailer, etc., ensure that the tanks are drained and the unit is secured. Use care when driving to avoid tipping the unit over in the vehicle. Damage can occur to the compressor or surrounding items if the compressor is t i p p e d . MOVING When moving the compressor, grasp the handle grip and carry the compressor as close to your body as possible. WARNING: Ensure proper footing and use caution when carrying compressor to avoid a loss of balance. Air Inlet Filter CAUTION: Do not operate without the air inlet filter. General Requirements The piping, fittings, receiver tank, etc. must be certified safe for at least the maximum working pressure of the unit. Use hard welded or threaded steel or copper pipes, cast iron fittings and hoses that are certified safe for the unit's discharge pressure and temperature. Use pipe thread sealant on all threads and tighten joints thoroughly to prevent air leaks. DO NOT USE PVC PLASTIC. CONDENSATE DISCHARGE PIPING To install a condensate discharge line, use piping at least one size larger than the connection. Connect the piping so that it is secured tightly and is routed to a suitable drain point. Use as short and direct a pipe as possible. Condensate must be disposed of in accordance with local, state, and federal laws and regulations. NOTE: All compressed air systems generate condensate that accumulates in any drain point (e.g. tanks, filter, aftercoolers and dryers). This condensate contains lubricating oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations. Operating Procedures PRE-START CHECKLIST 1. Ensure that the ON/OFF lever switch is in the OFF position. 2. Ensure that the tank is drained so that moisture, dirt, etc. can be e l i m i n a t e d . 3. Ensure that the tank pressure gage reads 0 PSI. 4. Ensure that the safety and drain valves are functioning properly. 5. Ensure that the drain valve is closed. 6. Check the oil level in the pump. NOTE: The air compressor is shipped without oil in crankcase. Add oil before using. 7. Ensure that all guards and covers are in place and securely mounted. Ensure that all labels are legible. Do not use the compressor until all these items have been verified. START-UP 1. Ensure that the ON/OFF lever on the pressure switch is in the OFF position. 2. Pull out and turn the regulator knob counterclockwise until it is ful- ly closed. Push in to lock. The regulated pressure gage should read 0 PSI. 3. Plug the power cord into a grounded outlet. 4. Move the ON/OFF lever to the ON position. Allow the compressor to reach cut-out pressure limit. This pressure will cause the compressor to shut down automatically. NOTE: When the compressor is started and the tank is empty, an air noise will be heard. This noise is normal as the cold start valves are allowing air to escape from the air compressor lines.
