ADJUSTING THE HANDPIECE
The handpiece knob and
the body (barrel) are
threaded together, allowing
the hose to be rotated
to the position the user
prefers. The length of the
handpiece can be extended
by unscrewing the knob and
body even more. NOTE: Extending the length may
cause a slight loss of power depending on the type
of work being done.
With the locking ring slightly loose, the handpiece
body and knob can be turned independently. Position
the Quick Change holder with the graver “point”
down and rotate the knob until the hose position is
the most comfortable. Once the hose and graver are
both positioned comfortably, tighten the locking ring.
HOW TO ATTACH NEW HOSE
Loosen the locking ring and remove the knob from
the handpiece. Remove the
old hose simply by cutting it
off close to the knob. With
a small punch, push the
hose/brass tting back into
the knob body. Remove the
brass tting (#004-422 Air
Hose Retainer) from the
old hose. Feed the new air
hose through the hole in the
knob
(FIG. 1). Insert the brass
tting into the end of the
hose making sure it is fully
seated. Moistening the
tting rst may help it slip
into the hose easier. Then
apply a small amount of
moisture or oil around the outside end of the hose
next to the brass tting and pull the hose back
(FIG. 2) into the knob until you see the tip of the
brass tting protrude through the side of the knob.
This must be an air tight t, so you will have to pull
somewhat hard (a few pounds, at least).
PUTTING A FLAT ON THE
BOTTOM OF HANDPIECE KNOB
(If Desired) If you choose to put a at on the knob
you should use the handpiece rst to be sure where
the hose “exit” is most comfortable for you. Note
critical dimensions below and warnings below.
IMPORTANT: IF TOO MUCH MATERIAL IS
REMOVED, KNOB WILL BE RUINED. (PART
#004-415) NOTE: Any damage from adding a at to
the knob is NOT covered by the warranty.
MAINTENANCE
The only basic maintenance for the GRS Monarch
Handpiece is keeping it clean on the inside.
Problems will occur if oil or moisture gets into the
handpiece, especially on the piston. If you notice
a loss of power or erratic performance, the FIRST
THING to check is to make sure the RECEIVER
(chuck) IS TIGHT IN THE HANDPIECE BODY.
Using a crescent wrench or pliers with a graver
inserted in the QC Holder, gently tighten receiver
clockwise (FIG. 3) If erratic
performance continues, then
disassemble and clean the
handpiece.
To disassemble the
handpiece, use the crescent
wrench or pliers to grip the graver (FIG. 3) and turn it
counterclockwise to loosen the chuck retainer. After
loosening, turn the chuck retainer out with your nger
tips (FIG. 4). As you pull out the chuck, there will be a

spring and piston.
Loosen the locking ring and
remove it (FIG. 5). Grip the
knob and turn the handpiece
body counter-clockwise until
it is out of the knob body
(FIG. 6).
Now, with the handpiece
disassembled, clean the
parts with a NON-residue
solvent like denatured
alcohol. Make sure the holes
in the handpiece body are
clear from dirt and debris.
DO NOT get moisture down
the air hose. If this happens
you will need to clear and
dry it before reassembly.
Before reassembly, make sure every thing
is completely dry. DO NOT OIL INSIDE THE
HANDPIECE. NO lubricant is required. Lubricant will
actually decrease performance!
REASSEMBLY NOTE:
There is an O-ring inside the knob that makes getting
the handpiece body to thread a little difcult when
reassembling. Use a very small amount of synthetic
lube or non-stick grease and create a thin lm around
the OUTSIDE of the shaft between the threads and
the end (see call out in FIG. 7).
NOTE: Do NOT use petroleum based oils - USE
ONLY Synthetic oils. Fossil oils can damage the
O-Rings.
See “Adjusting the Handpiece” on page 1 for
adjusting graver and hose position.

Please Note: the Palm Pad mounting screws
should only be lightly snug; over-tightening
can distort or damage the pad.
Type-E Palm Pads
The latest palm pad design for Airtact hand control is Type-E,
available in four sensitivity levels: 4, 6, 8, and 10. The handpiece
is more responsive (less force required to activate) with a lower
number palm pad installed.
Initially, palm pads can be stiff . This aff ects the feel and control.
Stiff ness may be reduced naturally with a few hours of use. To
reduce stiff ness quickly, bend and twist the control fl ap to soften.
When the preferred softness is nearly reached, stop and test
frequently to adjust until desired responsiveness is attained. The
rubber control fl ap can be formed for a custom feel as well.
Forming the Rubber Control Flap
The fl exible rubber control fl ap on the Palm Pad transforms hand
force into handpiece power by progressively covering a small air
vent hole in the upper rear of the Airtact handpiece knob.
Forming or bending the control fl ap one way (concave) increases
the required hand force; bending it the other way (convex)
decreases hand force.
To increase required hand force:
Bend the control fl ap into a more
concave shape. Bending the fl ap this
direction keeps the fl ap from sealing off
the Airtact knob hole until more hand
force is applied.
To decrease required hand force:
Bend the fl ap into a more convex shape
to decrease the hand force required.
This shape seals the Airtact Knob hole
with less force applied.
