on the bare pump when it cools down and a "milky" appearance in
compressor lubricant. You may be able to prevent moisture from
forming in the bare pump by increasing ventilation or operating for
longer intervals.

NOISE CONSIDERATIONS

Consult local officials for information regarding acceptable noise levels
in your area. To reduce excessive noise, use vibration mounts or
silencers, relocate the unit or construct total enclosures or baffle walls.

assistance.
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. The compressor or
surrounding items can be damaged if the compressor is tipped.
MOVING
When moving the compressor into a position for use, grasp the handle
grip and carry the compressor as close to your body as possible.
WARNING: Ensure proper footing and use caution when carrying
the 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 compressor'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, 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 on the engine is in the OFF position.
2. Ensure that the tanks are drained so that moisture, dirt, etc. can
be eliminated.
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 valves are closed.
6. Check the oil level in the pump.
7. Check the oil level in engine crankcase.
8. 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 engine is in the OFF position.
2. Pull out and turn the regulator knob counterclockwise until it is fully
closed. Push the knob in to lock it. The regulated pressure gage
should read 0 PSI.
3. Ensure that there is fuel in the fuel tank.
4. Turn the ON/OFF lever on the engine to the ON position.
5. Rotate the manual lock on the pilot valve into the in-line position to
assist with start up.
