4. Make sure any tube, pipe, fitting, or hose connected to the unit can withstand operating temperatures
and retain pressure.
5. Never use reducers in discharge piping. Keep all piping and fittings the same size in the piping system.
PRE-USE INSPECTION
1. The unit is shipped with pump break-in oil and should be ready to operate. Be sure to check for proper
oil level before running the compressor. Break in oil should be changed after 150 Hours of operation
(active pumping time). See maintenance section for more information on oil changes and frequency.
2. Check for proper belt tension. There should be ½ inch of belt slack/deflection. Refer to maintenance
section if adjustment is necessary.
3. Inspect belts for frays or unit for an excess buildup of black rubber dust indicating belt wear.
4. Check proper operation of all pop off safety valves on unit. Pull rings on valves to ensure they move
and are free of any obstructions. DO NOT pull the safety valve on the tank if there is air in the tank!
WARNING: Never use plastic (PVC) pipe for compressed air. Serious
injury or death could result. Piping MUST have a pressure rating of
200 PSI or greater.
Oil level should be to the center of the red circle in the sight glass. Oil
level WILL SLIGHTLY LOWER once the unit turns on and oil begins to
circulate.
Proper belt tension is determined by pressing midway
between the motor pulley and the pump flywheel.
