Operation
For use with 12-volt DC power outlets rated 15 amps or higher. Do not
use with older 8 amp cigarette lighter receptacles.
FOR LOW PRESSURE INFLATION - MANUAL SHUTOFF ONLY -
INFLATION OF ITEMS THAT REQUIRE LESS THAN 20 PSI
1. Plug the power cord into a power outlet. NOTE: Some vehicles require the engine to
be running to power the inflator.
2a. If inflating a low pressure tire (such as an ATV tire or lawn tractor tire), attach
universal adapter to valve stem with the locking lever in the open/up position. Press
the universal adapter completely onto the valve stem thread. Failure to do so could
lead to loss of tire pressure during this process.
b. If inflating a sports ball, insert a metal inflation needle into the universal adapter.
Make sure the needle is secure in the adapter.
3. When the universal adapter is firmly in place, press the locking lever down. (See
Figure 2).
4. Turn pressure selector dial until the desired pressure field reads “LO” (LO setting is
just below 20 psi setting). (See Figure 3).
5. Press power button. (See Figure 4).
6. When item reaches desired firmness, press power button again to stop inflation.
The actual pressure will then read on the digital gauge after the inflator has
stopped. (See Figure 3).
If inflator immediately stops inflating and shuts off, make sure the
universal adapter is pressed fully on to the tire valve stem or the metal
inflation needle is inserted correctly (See Figure 2).
7. If more inflation is needed, repeat steps 5 and 6.
8. When desired pressure is reached, raise universal adapter lever and remove from
the tire valve stem or remove the metal inflation needle.
Overinflation can be dangerous. Pay attention while inflating low
pressure items to prevent overinflation.
Do not allow inflator to run unattended while in “LO” setting.
FOR STANDARD TIRE INFLATION - AUTOMATIC SHUTOFF -
INFLATION OF TIRES BETWEEN 20 PSI AND 99 PSI
1. Attach universal adapter to valve stem with the locking lever in the open/up
position. Press the universal adapter completely onto the valve stem thread. Failure
to do so could lead to loss of tire pressure during this process.
2. When the universal adapter is firmly in place, press the locking lever down. (See
Figure 2).
3. Plug the power cord into a power outlet.
4. Turn the pressure selector dial until desired pressure is reached. (See Figure 3).
5. Press power button. (See Figure 4). Unit will turn off automatically when set
pressure is reached.
If inflator immediately stops inflating and shuts off, make sure the
universal adapter is pressed fully on to the tire valve stem (See Figure 2 ).
6. When desired pressure is reached, raise universal adapter lever and remove from
the tire valve stem or remove the metal inflation needle.
