* 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 SAe 5W-40 full synthetic oil,
change oil every 200 hours of operation or once a year, whichever
comes first.
+ Perform more frequent in dusty or humid conditions

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.
