test run &
break in
to test run and break in the air com-
pressor:
1. put on safety goggles, and place the
compressor on a solid, level surface.
2. make sure the on/off lever is in the
up or the OFF position, as shown in
figure 4.
6. observe the tank pressure gauge
( figure 6) to verify that the tank pres-
sure climbs to approximately 105-110
psi. When the tank reaches this pres-
sure, the motor will automatically shut
OFF.
note: If the compressor reaches 115-
120 PSI, and does not automatically
shut
OFF, lift the ON/OFF lever up to
shut the motor OFF before the pressure
climbs any higher. Adjust the pressure
switch as outlined on
Page 20.
3. double check the oil level sight glass to
make sure the crankcase oil is at the full
mark.
4. Connect the compressor to the power
supply.
5. leave the drain valve (figure 5) open,
push the switch to the down position
or the
ON position, and allow the com-
pressor to free-run for 15 minutes for
a no-load break in before closing the
drain valve and allowing it to build air
pressure.

mately 30 minutes of actual use (not
including the cool-down times), change
the compressor oil, as outlined in
changing oil on page 18.
