Operating Procedures; Pre-Start Checklist; Initial Set-Up; Start-Up - DeWalt D55140 Instruction Manual

PREPARATION FOR USE
Pre-Start Checklist (Fig. 1)
1. Ensure the On/Off switch (A) is in the OFF position.
2. Plug the power cord into the correct branch circuit receptacle. See
Voltage and Circuit Protection under Installation.
3. Ensure air tank is drained, see Draining Air Tank under
Maintenance.
4. Ensure the drain valve (H) is closed.
5. Ensure safety valve (G) is functioning properly, see Checking
Safety Valve under Maintenance.
6. Turn regulator knob (D) counterclockwise until fully closed. Ensure
regulated pressure gauge reads 0 PSI (0 kPa).
7. Visually inspect air hose, replace if needed.
8. Attach hose and accessories.
WARNING: Risk of unsafe operation. Firmly grasp air hose in hand
when installing or disconnecting to prevent hose whip.
&WARNING: Risk of bursting. Too much air pressure causes a
hazardous risk of bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories. The regulator outlet
pressure must never exceed the maximum pressure rating.
Initial Set.up (Fig. 1)
WARNING: Do not operate this unit until you read and understand
this instruction manual for safety, operation and maintenance
instructions.

1. Ensure the On/Off switch (A) is in the OFF position.
NOTE: If hose is not connected to Quick Connect body, pull coupler
back until it clicks to prevent air from escaping through the quick
connect.
2. Plug the power cord into the correct branch circuit receptacle. See
Voltage and Circuit Protection under Installation.
3. Open the drain valve (counter-clockwise) fully to permit air to
escape and prevent air pressure build up in the air tank during
the break-in period.
4. Move the On/Off switch to the ON position. The compressor will
start.
5. Run the compressor for 15 minutes.
6. After 15 minutes, close the drain valve by turning clockwise.
The tank will fill to cut-out pressure and the motor will stop.
7. Compressed air will be available until it is used or bled off.
OPERATING PROCEDURES
Start-up (Fig. 1)
1. Follow Pre-Start Checklist under Preparation for Use.
2. Move the On/Off switch to the ON position and allow tank pres-
sure to build. Motor will stop when tank pressure reaches
cut-out pressure.
CAUTION: Risk of unsafe operation. Compressed air from the unit
may contain water condensation. Do not spray unfiltered air at an
item that could be damaged by moisture. Some air operated tools
or devices may require filtered air. Read the instructions for the air
tool or device.
3. Adjust regulator (D) to desired setting. See Regulator under
Features.
