Maintenance Chart - DeWalt D55167 Manual De Instrucciones

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.
NOTE: Any service operations not included in this section should
be performed by a D WALT factory service center or a D
E
authorized service center.

Checking Safety Valve
WARNING: Risk of bursting. If the safety valve does not work
properly, over-pressurization may occur, causing air tank rupture or
an explosion.

WARNING: Risk from flying objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side
shields when using the compressor.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. NOTE: Ring may
be difficult to pull when air tank pressure is at 0 PSI. If the valve is
stuck or does not operate smoothly, it must be replaced with the
same type of valve.
Draining Air Tank (Fig. 1)
WARNING: Risk of unsafe operation. Air tanks contain high pres-
sure air. Keep face and other body parts away from outlet of drain.
Use eye protection ANSI Z87.1 [ANSI Z87.1 (CAN/CSA Z94.3)]
when draining as debris can be kicked up into face.
WARNING: Risk from noise. Use [ANSI S12.6 (S3.19)] ear
protection as air flow noise is loud when draining.
NOTE: All compressed air systems generate condensate that
accumulates in any drain point (e.g., tanks, filter, aftercoolers,
dryers). This condensate contains lubricating oil and/or substances
which may be regulated and must be disposed of in accordance with
local, state, and federal laws and regulations.
1. Ensure On/Auto/Off switch (A) is in the OFF position.
2. Move compressor into an inclined position so drain valve (H) is
at the lowest point (this will assist in removing moisture, dirt, etc.
from air tanks)
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.
CAUTION: Risk of Property Damage. Drain water from air tank may
contain oil and rust which can cause stains.
3. Place a suitable container under the drain valve to catch
discharge.
