Operating Procedures; Maintenance - DeWalt D55155 Instruction Manual

. 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 0 minutes.
6. After 0 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 and oil mist. Do not spray unfil-
tered air at an item that could be damaged by moisture. Some air
operated tools or devices may require filtered air. Read the instruc-
tions for the air tool or device.
. Adjust regulator (D) to desired setting. See regulator under
Features.
Shut-down (Fig. 1)
1 Move On/Off switch (A) is in the OFF position. notE: If finished
using compressor, follow Steps  - 6.
. Turn regulator knob (D) counterclockwise until fully closed. Ensure
regulated pressure gauge reads 0 PSI (0 kPa).
. Remove hose and accessory.
4. Drain the air tank, see Draining Air tank under Maintenance.
Ensure air tank pressure gauge reads 0 PSI (0 kPa).
WARNING: Risk of bursting. Drain air tank daily. Water will con-
dense 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, non-freezing
area.

MAInTEnAnCE

The following procedures must be followed when maintenance or
service is performed on the air compressor.
1. Ensure On/Off switch is in the OFF position.
. Remove air compressor plug from outlet.
. 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.
notE: Any service operations not included in this section should
e
be performed by a D WALT factory service center or a D
authorized service center.
