Preventative Maintenance
For best results, an inline water trap and oiler should
be installed. To maintain it, follow the manufacturers
recommendations for servicing the water trap and
oiler.
1. Guard against rough handling of the AirNut.
2. Keep the partial nut, thumb lever assembly and
the balancer’s arbor shaft clean and free of any con-
taminant.
3. Avoid using strong solvents and chemicals for
cleaning. Compressed air and a light penetrating oil
such as WD 40 may be used to clean any part of the
AirNut.
4. There is a filter on the inlet to the air chamber
where the air gun is positioned for inflating. This filter
may be cleaned as described above.

ice (800) 688-6359 for an authorized service center

Troubleshooting
The AirNut has proved to be a very durable piece of
equipment. If maintained and handled properly, it
should give many years of good service.
Should any service be required review the following
section.
Look at the parts illustration on page 5.
1. There are four metric allen screws holding the
handle body to the main casting.
Once the four metric screws are removed and the
handle body is removed, the inlet and outlet valve
assemblies can be removed for cleaning, repair or
replacement. The correct placement of their air check
balls and springs is critical.
The partial nut, thumb release lever and spring may
be serviced when the handle body is separated from
the main casing.
If the AirNut won’t activate, check for air pressure
when the air gun is depressed.
2. Make sure there are no kinked air hoses.
3. Disconnect the air supply from the regulator and
make sure that supply of air is reaching the regulator.
4. If air pressure is present at the regulator, begin to
disconnect at each joint from the regulator and make
sure that supply of air is reaching the regulator.
5. If air pressure is present at the regulator, begin to
disconnect at each joint from the regulator to the gun
until the problem is located.
Wear safety glasses. There may be high air
pressure.
6. If air pressure is coming from the air gun but the
AirNut won’t activate, the filter is suspect. Clean with
WD 40 or equivalent.
If it still won’t inflate…
7. Inoperative inlet valve assembly.
8. If an air leak is noted in/on the AirNut, locate the
source and clean, repair or replace the component
part.
If the AirNut won’t engage with the arbor shaft
threads…
9. Arbor shaft threads are dirty and needs cleaning.
10. Partial nut is dirty and needs cleaning.
11. Partial nut thumb release is in need of disas-
sembly, cleaning or repair.
If the previous doesn’t fix the problem, call customer
service (800) 688-6359 for an authorized service cen-
ter closest to you.
