operation
Before connecting an air tool to this air
compressor, have a general idea as to
what the CFm (Cubic Feet per minute) air
requirement is for your tool. if the tool has
a CFm requirement higher than what the
compressor can supply, the tool will oper-
ate poorly. Additionally the compressor will
likely run continuously to keep up with the
demand and overheat possibly causing
damage. however, the model t21888 is
equipped with a thermal overload. When
the core temperature of the motor reaches
an unsafe level, the thermal overload will
trip open and cut power to the motor.
if the thermal overload trips, the compres-
sor must be allowed to cool for 30 minutes,
then you can push the reset button shown
in
figure 8, and resume operations.
in the future, do not allow the compressor
to constantly run and overheat.

to use your air compressor:
1. put on safety glasses.
2. make sure the compressor lever is in
the down or the OFF position, as shown
in figure 9.

3. Close the tank drain valve.
4. double check the oil level sight glass
shown in figure 10 to make sure the
crankcase oil is at the full mark.

5. Connect the compressor to the power
supply.
6. Connect the tool air hose to the com-
pressor.
the right-hand connection point pro-
vides full tank pressure with minimum
air restrictions. the gauge above the
fitting shows full tank pressure.
the left-hand connection point pro-
vides regulated air pressure. the gauge
above the fitting shows the pressure
level being delivered to the tool.
leaving a compressor while it is
plugged in can cause fire. if a leak
develops, the compressor may run
continuously until it overheats and
catches fire. When not in use, always
disconnect the compressor from
power, and drain the air tank.
