* To check for air leaks apply a solution of soapy water around joints.
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: 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
identified in Fig. 2). Allow compressor to cool prior to servicing.
