Operating Procedures; Maintenance - DeWalt D55171 Instruction Manual

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 (turn lever 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/Auto/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 lever
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.
CAUTION: Risk of unsafe operation. Do not operate in vertical
position. Vertical position is for storage only.
2. Move the On/Auto/Off switch to the ON position and allow tank
pressure to build. Motor will stop when tank pressure reaches
cut-out pressure.
CAUTION: Risk of unsafe operation. Compressed air from the
unit may contain wa ter condensation and oil mist. Do not spray
un fil tered air at an item that could be damaged by moisture. Some
air op er ated tools or de vic es may require filtered air. Read the
in struc tions for the air tool or device.
3. Adjust regulator (F) to desired setting. See regulator under
Features.
Shut-down (Fig. 1)
1. Move On/Auto/Off switch (L) to the OFF position. nOte: If
finished using compressor, follow Steps 2 - 6.
2. Pull the regulator knob (F) out and turn counterclockwise until fully
closed. Ensure regulated pressure gauge reads 0 PSI. Push knob
in to lock in place.
3. Remove hose and accessory.
WARNING: Risk of unsafe operation. Firmly grasp air hose in hand
when installing or disconnecting to prevent hose whip.
4. Drain the air tank, see Draining Air tank under Maintenance.
Ensure air tank pressure gauge reads 0 PSI.
WARNING: Risk of bursting. Drain air tank daily. Water will
condense in air tank. If not drained, water will corrode and weaken
the air tank causing a risk of air tank rupture.
5. Allow the compressor to cool down.
6. Wipe air compressor clean and store in a safe, non­freezing
area.

MAINTENANCE

The following procedures must be followed when maintenance or
service is performed on the air compressor.
1. Ensure On/Auto/Off switch is in the OFF position.
2. Remove air compressor plug from outlet.
3. Drain air tank.
4. Allow air compressor to cool down before starting service.
nOte: All compressed air systems contain maintenance parts (e.g.,
oil, filters, separators) that are periodically replaced. These used parts
may contain substances that are regulated and must be disposed of in
accordance with local, state, and federal laws and regulations.
nOte: Take note of the positions and locations of parts during
disassembly to make reassembly easier.
