Condensate Discharge Piping; Pre-Start Checklist; Maintenance; Operating Procedures - DeWalt D55143 Instruction Manual

CONDENSATE DISCHARGE PIPING

To install a condensate discharge line, use piping at least one size
larger than the connection. Connect the piping so that it is secured
tightly and is routed to a suitable drain point. Use as short and
direct a pipe as possible. Condensate must be disposed of in
accordance with local, state, and federal laws and regulations.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g., tanks, filter, aftercoolers and
dryers). This condensate may contain substances which may be
regulated and must be disposed of in accordance with local, state
and federal laws and regulations.

Operating Procedures

PRE-START CHECKLIST

1. Ensure that the On/Off lever on the pressure switch is in the
OFF position.
2. Ensure that both tanks are drained so that moisture, dirt, etc.,
can be eliminated.
3. Ensure that the tank pressure gauge reads 0 PSI.
4. Ensure that the safety and drain valves are functioning properly.
5. Ensure that the drain valves are closed.
6. Ensure that all guards and covers are in place and securely
mounted. Ensure that all labels are legible. Do not use the com-
pressor until all of these items have been verified.
START-UP
1. Ensure that the On/Off lever on the pressure switch is in the
OFF position.
2. Pull out and turn the regulator knob counterclockwise until it is
fully closed. Push in to lock. The regulated pressure gauge
should read 0 PSI.
3. Remove the power cord from the cord wrap and plug into a
grounded outlet.
4. Move the On/Off lever to the ON position. Allow the compres-
sor to reach cut-out pressure limit. This pressure will cause the
compressor to shut down automatically.
NOTE: When the compressor is started and the tank is empty, an
air noise will be heard. This noise is normal as the unloader valve,
located in the pressure switch, is allowing air to escape from the air
compressor lines. This noise will also be heard when the unit shuts
off because the unloader valve is purging air from the lines.
5. Attach the hose and accessory.
6. Adjust the regulator to the desired setting.
NOTE: If any unusual noise or vibration is noticed, stop the com-
pressor and refer to the Troubleshooting Guide at the end of this
manual.
SHUT-DOWN
NOTE: NEVER stop the air compressor by unplugging it from the
power source. This could result in damage to the unit.
1. Ensure that the On/Off lever on the pressure switch is in the
OFF position.
NOTE: If finished using compressor, follow steps 2–7 below.
2. Unplug the cord from the outlet. When compressor is not in
use, utilize the cord wrap to keep the cord in place.
3. Turn the regulator knob counterclockwise until it is fully closed.
Ensure that the regulated pressure gauge reads 0 PSI.
4. Remove the hose and accessory.
5. Drain the air tanks.
6. Allow the compressor to cool down.
7. Wipe 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. Turn the On/Off lever on the pressure switch to the OFF
position.
2. Disconnect cord from electrical outlet.
