3. Ensure the drain valve (J) is closed.
4. Ensure safety valve (I) is functioning properly, see Checking
Safety Valve under Maintenance.
5. Check pump oil level, see Compressor Pump Oil under
Maintenance.
NOTICE: Do not operate without oil or with inadequate oil. D
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
items have been verified.
Initial Set-up (Fig. 1)
WARNING: Do not operate this unit until you read and
understand this instruction manual and the engine instruction
manual for safety, operation and maintenance instructions.
BREAK-IN PROCEDURE
NOTICE: 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 under-
stand the engine instruction's manual for safety, operation and
maintenance instructions.
4. Prepare engine for first time use,
WALT
e
see engine's instruction manual for
correct procedure.
5. Turn the engine ON/OFF switch (C)
to the ON position.
6. Place the fuel valve lever (O) in the
ON postion.
7. If the engine is cold, move the
choke (N) to the CLOSED position as shown. If the engine is
hot, move the choke to the OPEN position.
WARNING: Risk of unsafe operation. Pull starter grip slowly
until resistance is felt. Then pull starter grip (P) rapidly to avoid
kickback and prevent hand or arm injury.
NOTICE: Do not allow the starter grip to snap back. Return it gently
by hand.
NOTE: If the engine does not start, check the oil level and add oil
as needed.
NOTE: To ensure maximum oil lubrication, place the unit on a level
surface.
8. As the engine warms up, move the choke to the OPEN position.
9. 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.
10. Rotate the manual lock on the unloader valve into the closed
position so the air tank pressure can build.
