Checking Safety Valve; Checking Air Filter - DeWalt DXCM301 Instruction Manual

WARNING: Risk of unsafe operation. Unit cycles automati-
cally when power is on. When performing maintenance, you may
be exposed to voltage sources, compressed air, or moving parts.
Personal injuries can occur. Before performing any maintenance or
repair, disconnect power source from the compressor and bleed off
all air pressure.
To ensure efficient operation and longer life of the air compressor
outfit, a routine maintenance schedule should be prepared and fol-
lowed. The following routine maintenance schedule is geared to an
outfit in a normal working environment operating on a daily basis.
If necessary, the schedule should be modified to suit the condi-
tions under which your compressor is used. The modifications will
depend upon the hours of operation and the working environment.
Compressor outfits in an extremely dirty and/or hostile environment
will require a greater frequency of all maintenance checks.
NOTE: See Operation section for the location of controls.

Checking Safety Valve

WARNING: Hot surfaces. Risk of burn. Tubes, pump head, and
surrounding parts are very hot, do not touch (see the Hot Surfaces
identified in Fig. 1). Allow compressor to cool prior to servicing.
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.
WARNING: Risk from noise. Use ear protection (ANSI S12.6
(S3.19) as air flow noise is loud when draining.
Before starting compressor, pull the ring
on the safety valve (G) to make sure
that the safety valve operates freely. If the
valve is stuck or does not operate smoothly,
it must be replaced with the same type
of valve.

Checking Air Filter

WARNING: Hot surfaces. Risk of burn. Tubes, pump head, and
surrounding parts are very hot, do not touch (see the Hot Surfaces
identified in Fig. 1). Allow compressor to cool prior to servicing.
A dirty air filter will not allow the compressor to operate at full
capacity. Keep the air filter clean at all times.
1. Ensure Auto/Off switch (B) is in the OFF (O) Position.
2. Allow unit to cool.
3. Unsnap the air filter cover to
remove (S).
4. Check the filter elements (T).
If they are dirty, blow
compressed air through the
filter element for 10-15
seconds or replace if needed.
If the filter is filled with paint,
replace it.
5. Place element into housing and reattach the air filter cover.
CAUTION: Risk of unsafe operation. Do not operate without air
filter.
