Digital Gauge Display (Fig. A, E, F)
The digital gauge display
amount of pressure being applied to the item being inflated
and also serves as a pressure gauge.
Refer to the Using the inflator as a Pressure gauge section.
To turn the digital gauge display on, install the battery
pack 11 into the inflator and squeeze the trigger switch
Refer to the switching On section.
Switching On (Fig. A, F)

WARNING: Risk of bursting. Do not leave unit
running unattended. Overinflation of tires and
other items could result in serious injury and
property damage.
nOTE: When powered on, the digital gauge display 4 on
the inflator will remain on for approximately 0.5 minutes
before the display shuts off/goes into sleep mode. This
occurs when the unit is not operating. To wake up the
system, press the trigger switch 1 . At this time the digital
gauge display will turn on and the inflator is ready for use.
To Inflate Using High Pressure (Fig. A, F)

WARNING: Risk of bursting. Excessive air pressure
may cause a hazardous risk of bursting or personal
injury. Check the manufacturer's maximum pressure
rating for items being inflated.

Improperly attached accessories or hoses can become
detached under pressure and can cause serious injury.
Possible air leaks can cause false pressure readings.
Make sure that all connections are secured tightly.
nOTE: If the pressure rating for the item being inflated is
above 30 PSI, note that the maximum run time is 5 minutes.
The high-pressure air hose
that need more air pressure, such as tires and basketballs.
The air chuck on the high-pressure air hose can be used
without an adaptor to inflate any application that has a valve
stem that fits the air chuck opening.
1. Remove the high-pressure air hose
storage area .

2. Attach a nozzle as described in the Fitting the
Accessories section. Attach the air chuck
stem to inflate a tire, or attach an accessory to inflate a
ball or other inflatable.
3. Attach or insert the nozzle into the object being inflated.
4. Squeeze the trigger switch
readout will appear on the digital gauge display
5. To stop the inflator at any time, release the trigger switch.
nOTE: The pressure readout on the digital gauge display
while inflating is a measurement of the changing pressure
between the item and the air hose. To get an accurate
reading, release the trigger switch and wait for the readout
to adjust. The gauge will indicate the pressure in PSI. When
the desired pressure is reached, release the trigger switch
and disconnect the inflator.

a couple of seconds. This is normal.
Using the Inflator as a Pressure Gauge
(Fig. A)

WARNING: Operating a vehicle with improperly
1 .
inflated tires could result in serious injury.
Your inflator does not have a calibrated pressure gauge;
therefore exact values are not binding. When using the
inflator as a pressure gauge, please verify pressure with a
separate gauge in advance.
1. Connect the high-pressure air hose
be checked.
2. Squeeze the trigger switch
3. The digital gauge will display the item's pressure.
4. After checking, detach the high-pressure air hose
from the application and return the air hose to the
storage area.
