5. Check pump oil level, see Compressor Pump Oil under
Maintenance.
CAUTION:
Do not operate without oil or with inadequate oil.
D
EWALT is not responsible for compressor failure caused by
inadequate oil.
6. Check engine's oil and fuel level, see engine's instruction manual
for correct procedures.
7. Visually inspect drive belt. Replace belt if frayed, cracked, or worn.
NOTE: Outer belt cover must be removed to inspect drive belt.
8. Ensure all guards, covers, and labels are in place, legible (for
labels) and securely mounted. Do not use compressor until all

Initial Set-up
Read safety instructions before setting-up air compressor.
BREAK-IN PROCEDURE
WARNING: Risk of property damage. Serious damage may result
if the following break-in instructions are not closely followed.
This procedure is required:
• Before the air compressor is used for the first time.
• When the unloader valve has been replaced.
• When the compressor pump has been replaced.
The procedure:
1. Follow Pre-Start Checklist under Preparation for Use.
2. Rotate the unloader's manual lock to the open position to
prevent air tank pressure buildup.
3. Open the pressure regulator. Pull regulator knob (F) out and
rotate clockwise until it stops.
WARNING: Do not operate this unit until you read and understand
the engine instruction's manual for safety, operation and maintenance
instructions.
4. Prepare engine for first time use, see engine's instruction manual
for correct procedure.
5. Turn the engine ON/OFF switch (C) to the ON Position.
6. Start engine, see engine's instruction manual for correct
procedure.
7. Run the air compressor for 30 minutes to seat the rings and
lubricate all the internal surfaces. Ensure there is no pressure
build up in the air tank by observing the reading on the air tank
pressure gauge.
8. Rotate the manual lock on the unloader valve into the closed
position so the air tank pressure can build.
9. Close the pressure regulator. Rotate the regulator knob (F)
counterclockwise to its built-in stop and push knob in to lock in
place. This will allow air to build pressure in the air tank.
10. Compressed air will be available from the hose air outlet until it
is used up or bled off.
