Break-in Procedure


CAUTION: 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 put
into service for the first time and when the check valve or a
compressor pump/motor has been replaced.
1. Ensure the On/Off switch
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
Assembly and Adjustments.
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 20 minutes.
6. After 20 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. A)
1. Follow Pre-start Checklist under Preparation for Use.
2. Move the On/Off switch
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 to desired setting. See Regulator
4
under Components.
Shut-down (Fig. A)
1. Move On/Off switch is in the OFF position. nOTE: If
1
finished using compressor, follow Steps 2 - 6.
2. Turn regulator knob 4 counterclockwise until fully
closed. Ensure regulated pressure gauge reads 0 PSI
(0 kPa).
3. 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 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.
1 is in the OFF position.
1 to the ON position and
6. Wipe air compressor clean and store in a safe, non-
freezing area.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.
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.
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.
nOTE: Any service operations not included in this section
should be performed by a D
e
a D WALT authorized service center.

* To check for air leaks apply a solution of soapy water around joints.
While compressor is pumping to pressure and after pressure cuts out,
look for air bubbles to form.
** The pump oil must be changed after the first 20 hours of operation.
Thereafter, when using SAE 5W-40 full synthetic oil, change oil every
200 hours of operation or once a year, whichever comes first.
+ Perform more frequent in dusty or humid conditions
Checking Safety Valve (Fig. B)

WARNING: Hot surfaces. Risk of burn. Aftercooler,
pump head, and surrounding parts are very hot, do
not touch (see the Hot Surfaces identified in Fig. B).
Allow compressor to cool prior to servicing.
