NOTICE:
Always leave low pressure hose free of obstructions and
and remove the pinch valve adaptor when not in use.
Overheating could occur if low pressure hose is blocked.
DEFLATING WITH THE LOW PRESSURE HOSE
See Figure 7, page 11.
The low pressure hose, when placed in the deflator port, can
be used to remove air from inflated items.
 Place the hose inside the deflator port.
 Press the mode/power button on the side of the inflator
to turn on the digital gauge.
 Press the mode/power button again to select the low
pressure mode.
 Press the start/stop button to start deflating.
 When the item has been deflated, press the start/stop
button to stop deflating.
 Remove the hose by pulling it from the deflator port.
 Store the hose in the hose wrap on the left side of the
unit.
INFLATING WITH THE HIGH PRESSURE HOSE
See Figure 8, page 11.
The air chuck on the high pressure hose can be used without
adaptors to inflate tires or with any application that has a
valve stem that fits the air chuck opening.
NOTE: When inflating items of 10 PSI or less, inflate in short
bursts and check after each burst by feel or with a calibrated
measuring device to determine accurate pressure.
 Press the mode/power button to turn on the digital gauge.
The unit will start up in high pressure mode by default.
NOTE: Make sure digital gauge is set at 0 before use. If
gauge reads "Err" or needs resetting, press and hold both
the mode/power button and start/stop button for about
5 seconds.
 Set desired pressure.
 Thread air chuck onto the valve stem, making sure it is
tightened securely. Do not cross-thread.
NOTE: The current air pressure inside the item will be
shown on the display.
 Press the ( + ) or ( – ) button to select the needed air pres-
sure. Press and hold the ( + ) or ( – ) button to increase or
decrease the air pressure in 5 lb. increments.
 Press the start/stop button to start inflating.
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
reading, stop inflating and follow above instructions for
reading the air pressure.
OPERATION
NOTE: Stand 10 feet away from item during inflation.
 Turn off the inflator and store the hose in the hose wrap
on the side of the unit.
 Press and hold the mode/power button to deactivate the
display.
INFLATING MANUALLY FOR HIGH
PRESSURE APPLICATIONS
 Connect the high pressure hose to item to be inflated.
 Press mode/power button to select high pressure.
 Press and hold start/stop button until desired pressure
is reached.
 Turn off the inflator and store the hose in the hose wrap
on the side of the unit.
ACCESSORIES
See Figures 9 - 12, pages 11 - 12.
The supplied accessories perform a variety of functions.
The tapered adaptor can be used on smaller pinch valves
to inflate items like floats and children's toys, which usually
require the user to inflate them by blowing air into them. The
sport ball needle can be used to inflate any type of sports ball
or any other item that requires an inflation sport ball needle.
NOTE: When inflating items of 10 PSI or less, inflate in short
bursts and check after each burst by feel or with a calibrated
measuring device to determine accurate pressure.
To use the sport ball needle:
 Insert sport ball needle into sports ball valve and inflate.
 Remove sport ball needle after inflation.
NOTE: Pressure required for most sports balls is too low for
accurate reading on gauge.
The Presta valve adaptor can be used for Presta valve stems
as described below. Before inflating a tire with a Presta
valve, loosen the locking nut on the valve stem to inflate.
Once inflation is complete, tighten the locking nut to seal
the tire valve.
To use the Presta valve adaptor:
 Thread Presta valve adaptor into the air chuck on the end
of the high pressure hose.
 Loosen Presta valve locking nut on the Presta valve stem.
 Thread the Presta valve adaptor onto the Presta valve
stem. Tighten firmly, being careful not to cross-thread.
 Inflate as described previously in Inflating With the High
Pressure Hose.
 After inflation, remove air chuck and tighten locking nut.
 Remove the Presta valve accessory and return to the
storage area.
 Remove the hose and store in the hose wrap on the right
side of the unit.
