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 engine START/RUN/OFF switch (C) is in the OFF
position.
2. Place a suitable container under the drain valve to catch
discharge.
3. Grasp black lever on drain valve.
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.
4. Slowly rotate lever to gradually bleed air from air tank.
5. When air tank pressure gauge reads 10 psi, rotate valve to the
fully open position.
6. Close drain valve when finished.

CHECKING OIL
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. 2). Allow compressor to cool prior to
servicing.
CAUTION: Risk of Unsafe Operation. Overfilling with oil will cause
premature compressor failure. Do not overfill.
NOTE: When filling the crankcase, the oil flows very slowly into the
pump. If the oil is added too quickly, it will overflow and appear to
be full.
1. Ensure engine START/RUN/OFF switch (C) is in the OFF
Position.
2. Place unit on a flat level surface.
3. Remove oil fill plug (K).
4. Check the oil level. Oil should not

exceed top raised line on side of crack-
case. (Oil will be even with bottom of
threads in crankcase fill port), if needed
add D
eWALT synthetic oil to the proper
level.
5. Replace oil fill plug and tighten
securely.
CHANGING OIL
NOTE: Pump oil contains substances that are regulated and must
be disposed of in accordance with local, state and federal laws and
regulations.
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. 2). Allow compressor to cool prior to
servicing.
1. Ensure engine START/RUN/OFF switch (C) is in the OFF
position.
2. Allow the unit to cool.
3. Disconnect spark plug wire.
4. Drain air tank.
5. Locate a suitable container under pump drain plug (L).
6. Remove the oil fill plug (K) from crank case.
7. Remove the oil drain plug (L).
8. Allow ample time for all oil to drain out. (Tilting the compressor
towards the drain plug will assist in draining.)
9. Install the oil drain plug.
