OPERATiON
QUiCk SHUTOff SWiTCH
See Figure 15.
Depress the quick shutoff switch at any time to stop the
inflator.
DiGiTAL GAUGE
See Figures 15.
NOTE: Digital gauge displays pressure of high
pressure hose only. Preset features apply to high pressure
applications only.
The digital gauge on the inflator is multifunctional. It serves
as a pressure gauge, monitors the amount of pressure being
applied to the item being inflated, and can change air pres-
sure measurement units from PSI to BAR to KG/CM
 .
To turn the digital gauge ON, press the ON/RESET button
or depress the switch trigger.
NOTE: Make sure digital gauge is set at 0 before use. If gauge
reads “Err” or needs resetting, press and hold
ON/RESET
button for 4-7 seconds.
NOTE: The digital gauge will automatically shut off when not
in use for  and a half minutes or more.
To use the pressure gauge feature:

Turn digital gauge on by pressing ON/RESET button or
depressing and releasing switch trigger.
 Place air chuck over valve stem and lock in place. Readout
will appear on gauge.
NOTE: The pressure readout on the gauge while inflating
is a measurement of the fluctuating pressure between the
item and the high pressure hose. To get an accurate read-
ing, stop inflating and follow above instructions for reading
the air pressure.

To switch from PSi, kG/CM 2 , and BAR:
 With gauge ON, press and hold down ON/RESET button
for a t least 7 seconds.
 The current measuring unit will flash. Press the
ON/RESET button again to select the desired measur-
ing unit.
 The setting takes effect after the display stops flashing.
(4-7 seconds)
NOTE: After preset pressure has been set, pressure setting
stays in the gauge memory for 10 seconds. To recall the
previous pressure setting for up to 10 seconds after infla-
tion, press the (
+ ) or ( - ) button.
To reset preset pressure, press and hold the ON/RESET
button.

 Connect either high or low pressure hose to item to be
inflated.
 Depress and hold switch trigger until desired pressure is
reached.
 Release the switch trigger.

NOTE: Digital gauge displays pressure of high pressure
hose only.

With gauge ON, press and hold down ( + ) or ( - ) buttons
to select desired shutoff pressure.
NOTE: Numbers will flash while setting pressure. Holding
buttons down will make the pressure number increase/
decrease faster.
 Depress switch trigger.
 Push the lock-on button forward.
 Release the switch trigger and the inflator will continue
running.
NOTE: For preset pressures of 39 PSI, .68 BAR, or .74
KG/CM
 or less, the unit will automatically stop just short
of the preset pressure. Manually depress the switch trigger
again to release the lock-on button and provide an additional
short “burst” of air to achieve preset pressure.
For preset pressures of 40 PSI, .75 BAR, or .74 KG/
CM, or greater, the unit will automatically stop at 40 PSI,
.75 BAR, or .74 KG/CM regardless of preset pressure
setting. This feature helps guard against over inflation and
possible bursting. Manually depress the switch trigger again to
release the lock-on button and continue inflating by hold-
ing the trigger in the
ON position to achieve desired pres-
sure. Shutoff will occur again just before target pressure is
reached.
NOTE: Read actual pressure only when unit is not
operating.
