Airtact. If this happens, your Touch Element will not work
properly (selector switches should both be positioned to same
handpiece).
Airtact Palm Element:
• Properly positioned in the hand, the Airtact Palm Elements
respond not only to forward push, but also downward push
and hand squeeze. This blend of force is what gives Airtact
a full range of control. If the Palm Element seems a little
too responsive at first, loosen your grip and pressure on the
handpiece.
• When using the Airtact, the position of the Palm Element
knob is important and affects the response. Make sure both
hoses are not obstructed the flap is placed against your palm.
IMPORTANT: there are two different aspects to positioning
the Palm Element. One is the location of the control flap in the
palm, the other is the rotational orientation of the knob itself
on the handpiece which changes the control flap position in
rotation. Different people will likely have different preferences.
Agree on what is best at first.
• Airtact Palm Pads can be quickly tuned for harder or easier
actuation using a razor knife or by grinding (with flex-shaft,
Dremel, NSK E-Max, etc.). We suggest using the stock touch
elements for a while to get a feel for the Airtact system.
Remember, this system is very user friendly and can be
customized to suit your needs or preferences. See fig. 3.
Airtact FootPod:
• The FootPod element connects to either 1 or 2 twist-lock ports
on the Airtact face. To switch to the FootPod simply move the
Airtact paddle switch to the port for the FootPod and you will
have foot control.
AIRTACT TROUBLESHOOTING
Your Airtact control system is a simple, virtually maintenance-free
tool that was designed to give you years of trouble-free service.
One item is required to insure this reliability, your compressed air
supply.
Your air supply MUST provide clean, dry, and oil-free air. We
suggest using an oil-free compressor with all GRS equipment.
If you are using an oil-type compressor you MUST have an oil
removal filter (coalescing type) in the line to your machine. If
you are unsure of this requirement, please call 800-835-3519
or 620-343-1084 and ask for Technical Services. Failure to
provide a properly prepared air supply will eventually lead to
erratic performance and can damage your equipment.

CONTAMINATION IS NOT COVERED BY WARRANTY.
The touch elements are mechanically simple and their sole
purpose is to provide a variable restriction to the air control
circuit. When installing a new or existing touch element, take time
to clean the hand piece first as this will ensure everything is fresh
to start. Install the touch element of your choice and make sure
all the hose connections are secure.
TOUCH ELEMENT TROUBLESHOOTING
If you suspect the handpiece is not responding properly, you
can easily test the touch element and handpiece for proper
function. Unhook the twist lock connector holding the small hose
from the Airtact unit. Place your finger over the now open port
on the Airtact face. You can also check handpiece operation
by moving the selector switch to the center position. This over-
rides the Touch Element and will allow continuous handpiece
operation. Your handpiece should now run consistently as long
as your finger is covering this port or the selector switch is in
the center position. If it does not, there is something amiss with
your handpiece. This may require cleaning the piston, spring,
and bore to re-establish consistent operation. If the handpiece is
working correctly, the next step is to check the Touch Element for
blockage. Carefully inspect the touch element for any debris or
abnormal wear on the palm element, gently lift the flap and check
for obstructions.
Airtact is purposely designed for the low cost evolution of touch
elements and even the ability for the end user to make their own.
Expect new and exciting developments in the Airtact product line
as the touch element designs are constantly evolving. Be sure
to check with www.airtact.com for what is new and additional
instructions and tips.
TIPS & TRICKS
1. To begin, set Airtact pressure at 12psi. This gives a full power
range for most handpieces.
2. Remember: With a foot control it doesn’t matter how tightly
you squeeze the handpiece. With Airtact hand controls, it
does and that’s an advantage once you are familiar with it.
Expect a learning period ... and relax!
3. Try less Airtact pressure (4-6psi) for fine shading as this limits
the maximum power. Put the Control Port Switch in the middle
to start the handpiece and adjust the Airtact pressure to the
suggested 4-6 psi (.3-.4 bar) then move the Control Port
Switch to the handpiece you are using.
WARRANTY
Each Airtact unit, including the handpiece Touch Element knobs
(excluding rubber Touch Pads) and Foot Pod control carries a
full 2-year warranty covering parts and labor. If warranty repair
is needed, the customer should contact the selling dealer for
more information before returning item for repair.
These units are designed for reliable operation using most
sources of compressed air. However, some air supplies
contain excessive water, oil, dirt, rust, or other contaminant’s.
The unit’s built-in filter is a final filter to protect against
normal dirt and water. If your compressed air has excessive
contaminant’s, you should install the necessary filter(s) and
water trap(s) ahead of your unit.
Oil contamination can be gradual and subtle. If you notice an
oil residue (usually a yellow to brown colored sticky or liquid
residue) in the unit’s filter bowl or handpiece / throttle hose,
you probably have an oil problem in your compressed air.
Older oil-lubricated and “silent” compressors that use internal
oil are more likely to cause oil contamination. If this occurs,
install a Coalescing Oil Filter (GRS #004-579 or equivalent).
