Checking Oil; Changing Oil - DeWalt D55394 Instruction Manual

Purchase replacement parts from your local dealer or authorized
service center. Always use identical replacement parts.
7. Place element back in filter base.
8. Reconnect filter top to filter base. While pushing in, rotate clock-
wise 5 degrees.
CAUTION: Risk of unsafe operation. Do not operate without air
inlet filter.
Draining Air Tank (Fig. 1)
WARNING: Risk of unsafe operation. Risk from noise. Air tanks
contain high pressure air. Keep face and other body parts away from
outlet of drain. Use safety glasses [ANSI Z87.1 (CAN/CSA Z94.3)]
when draining as debris can be kicked up into face.
WARNING: Use ear protection [ANSI S12.6 (S3.19)] 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/Off switch is in the OFF position.
2. Place a suitable container under the drain valve to catch
discharge.
WARNING: Risk of bursting. Water will condense in the 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. Grasp black lever on drain valve (J).
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 valves when finished.
Compressor Pump oil (Fig. 1)

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 On/Off switch is in the OFF position.
2. Place unit on a flat level surface.
3 Remove dipstick (K) and wipe clean.
4. Insert and remove dipstick without
threading dipstick into crankcase as
shown in figure.
5. Check the oil level on dipstick.
If oil level is at or below "Add",
oil needs to be added. Add D
synthetic oil to the proper maximum level as shown in figure.
6. Replace dipstick/oil fill plug and tighten securely.
