While compressor is pumping to pressure and after pressure cuts out,
look for air bubbles to form.
** The pump oil must be changed after the first 20 hours of operation.
Thereafter, when using DeWALT synthetic or SAE 40, non-detergent
air compressor oil, change oil every 200 hours of operation or once a
year, whichever comes first.
+ Perform more frequent in dusty or humid conditions
Checking Safety Valve (Fig. 1)
WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head,
and surrounding parts are very hot, do not touch (see the Hot
Surfaces identied in Fig. 2). 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.
Before starting compressor, pull the ring on the safety valve 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 Element (Fig. 1)
WARNING: Hot surfaces.Risk of burn.Aftercooler,pump head,and
surrounding parts are very hot, do not touch (see the Hot Surfaces
identied in Fig. 2). Allow compressor to cool prior to servicing.
1. Ensure the On/Off switch (A) is in the OFF position.
2. Allow unit to cool.
3. Remove air filter (N) from unit.
4. Carefully pry filter top from base.
5. Remove element from filter base.
6. If element needs cleaning, blow out with air. Replace if
needed. Purchase replacement parts from your local dealer or
authorized service center. Always use identical replacement
parts.
7. Place element back in filter base.
8. Snap filter top to filter base.
9. Reassemble air filter to unit. Ensure exhaust outlet points
down.
CAUTION: Risk of unsafe operation. Do not operate without air
inlet lter.

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. Use ear
protection [ANSI S12.6 (S3.19)] as air ow 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. Move compressor into an inclined position so drain valve (J) is
at the lowest point (this will assist in removing moisture, dirt,
etc. from air tanks)
3. Place a suitable container under the drain valve to catch
discharge.
4. Grasp knurled knob on drain valve.
5. Slowly rotate knob to gradually bleed air from air tank.
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.
6. When air tank pressure gauge reads 10 PSI (68,9 kPa), rotate
valve to the fully open position.
7. Close drain valve when finished.
Compressor Pump Oil (Fig. 1)
CHECKING OIL
WARNING:Hot surfaces. Risk of burn. Aftercooler, pump head,
and surrounding parts are very hot, do not touch (see the Hot
Surfaces identied in Fig. 2). Allow compressor to cool prior to
servicing.
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. Reinsert dipstick fully into oil fill port for a few
L
K
seconds to allow oil to collect on the
dipstick.
5. Remove oil dipstick to read oil level. Oil
should not exceed top raised line on
dipstick. If oil is below lower mark, add
same type of oil in crankcase and follow
Steps 4 - 6.
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.
CAUTION: Risk of unsafe operation. Overlling
with oil will cause premature compressor failure. Do
not overll.
6. Replace dipstick.
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.

GLOSSARY
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air
delivery.
PSI: Pounds per square inch; a unit of measure of pressure.
kPa (kilopascal): Metric pressure measurement. 1 kilopascal
equal 1000 pascals.
Code Certication: Products that bear one or more of the
following marks: UL, CUL, ETL, CETL, have been evaluated
by OSHA certified independent safety laboratories and
meet the applicable Underwriters Laboratories Standards
for Safety.
Cut-In Pressure: While the motor is off, air tank pressure drops
when accessory is used. When the tank pressure drops to a
certain low level the motor will restart automatically. The low
pressure at which the motor automatically restarts is called
cut-in pressure.
Cut-Out Pressure: When an air compressor is turned on
and begins to run, air pressure in the air tank begins to
build. It builds to a certain high pressure before the motor
automatically shuts off, protecting your air tank from
pressure higher than its capacity. The high pressure at which
the motor shuts off is called cut-out pressure.
Branch Circuit: The circuit carrying electricity from electrical
panel to outlet.
Duty Cycle: For proper operation of your air compressor, it is
recommended that a 50% duty cycle be maintained; that is,
the air compressor should not run more than 5 minutes in any
10 minute period.
