Operating Instructions
ASSEMBLY/DISASSEMBLY
To connect the air hose to the
ComPact Air Drive II:
Retract the hose coupling collar. Insert the air
drive coupling stem completely into the hose
coupling. Release the hose coupling collar to
secure the connection.
To disconnect the air hose from the
ComPact Air Drive II:
Press the connectors firmly together and
simultaneously retract the hose coupling
collar until it disengages.
To install an attachment:
Insert the attachment into the air drive
coupling until the parts engage. It is not
necessary to operate the release button
for installation.
To remove an attachment:
Press the release button and remove
the attachment.

OPERATION
Speed Control
For forward (clockwise) rotation, press the variable-
speed trigger of the air drive. Press both triggers
for reverse (counterclockwise) rotation. Speed
correlates directly to the amount of pressure on
the variable-speed trigger and can be varied
continuously from 0 to 900 rpm.

REVERSE
(both triggers)

IMPORTANT
• Use only dry, filtered compressed air or nitrogen
to power the ComPact Air Drive II. Never operate
air powered machines with oxygen; it creates a
danger of fire and explosion.
• Recommended operating pressure, with the
instrument running, is 90 psi (6 bars).
• Be sure that all attachments and instruments
are inserted securely before operating the
air drive.
• Inspect instruments for wear and/or damage
after each use. Do not use dull, damaged or
corroded drill bits or other instruments.
Air Control Valve
The ComPact Air Drive II air control valve controls
the regulation of maximum speed and power.
Turning the air control valve clockwise will
increase power; turning counterclockwise will
decrease power.
IMPORTANT
To prevent injuries, the air control valve
should always be turned to the “off” position
when inserting or removing instruments
from the attachments.

Operating Instructions (continued)
Quick Coupling for K-wires [511.79]
For insertion of K-wires from 0.6 mm to
3.2 mm diameter.
See page 4 for installation and removal
of attachments.
IMPORTANT
To prevent injuries, the air control valve
should always be turned to the “off” position
when inserting or removing K-wires.
To insert the K-wire into the Quick
Coupling for K-wires:
Set the adjustment sleeve dial to the K-wire
diameter. Insert the K-wire into the front
opening and set to the desired working depth.
Note: The K-wire is “presqueezed” upon
insertion into the coupling to prevent slippage
during handling. Pulling back on the lever
grasps the K-wire securely for insertion
into bone.
To insert a K-wire into bone:
Grasp the K-wire by pulling the lever against
the handpiece, and press the lower (forward)
trigger.
To remove a K-wire from bone:
Slide the drive unit and coupling over the
K-wire. Grasp the wire by squeezing the lever
toward the handpiece and press both triggers
simultaneously (reverse) to remove the wire
from the bone.

IMPORTANT
To prevent injuries, the air control valve
should always be turned to the “off” position
when inserting or removing instruments
from the Quick Couplings.
To insert an instrument into the
Large Quick Coupling:
Retract the collar of the Large Quick Coupling
and insert the instrument shaft completely with
a slight rotation. When the shaft is fully inserted,
release the collar. Pull on the instrument slightly
to ensure that it is held securely.
To insert an instrument into the
