points (R) when transporting. Use care when driving so to avoid tipping the unit over in the vehicle. Damage can occur to the unit or surrounding items if unit is tipped. Use a ramp if loading or unloading the unit from a height of more than 12" (304.8 mm).

LIFTING

Always use two people when lifting and lift from the recommended lift points (S).

WARNING: Risk injury from lifting. Unit weighs more than 160 lbs. (72.6 kg) Do not move or lift without assistance.

MOVING

1.Grasp handle (P) of compressor, and lift compressor high enough so unit can be rolled on the front tires.

WARNING: Risk of unsafe operation. Ensure proper footing and use caution when rolling compressor so that unit does not tip or cause loss of balance.

2.When location is reached slowly lower rear of compressor to ground. Always store compressor in a horizontal position. NOTE: Do not store in a standing position.

NOTE: Should the unit tip over, hard starting and smoking will occur due to oil spillage.

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 units discharge pressure and temperature. Use pipe thread sealant on all threads, and tighten joints thoroughly to prevent air leaks. DO NOT USE PVC PLASTIC.

WARNING: Risk of bursting. Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst from air pressure. Use only metal pipe for air distribution.

CONDENSATE DISCHARGE PIPING

If installing a condensate discharge line, the piping must be at least one size larger than the connection, as short and direct as possible, secured tightly and routed to a suitable drain point. 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., tank, filter, aftercoolers, dryers). This condensate contains oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations.

PREPARATION FOR USE

Pre-Start Checklist

1.Ensure engine ON/OFF switch (C) is in the OFF Position.

2.Ensure air tank is drained, see Draining Air Tank under Maintenance.

3.Ensure the drain valve (J) is closed.

4.Ensure safety valve (I) is functioning properly, see Checking Safety Valve under Maintenance.
