handpiece and irrigation pump. Releasing
the footswitch will stop the motor/handpiece
and pump.
9. Calibration of Handpiece
- Because
variations in handpiece efficiency can
cause inaccuracies in torque, it is essential
to routinely calibrate the handpiece/motor.
This will maintain optimal performance from
the System. It is recommended to calibrate
the System daily, even if using the same
handpiece, or whenever a handpiece is
changed.
Handpiece calibration consists of either a
one-part or two-part procedure, depending
on which type handpiece is used:
Part-1: “Free Run” Calibration -
Performed on both increaser and
reduction type handpieces.
Part-2: Dynamometer “Dyno”
Calibration -
Performed only on
reduction type handpieces (4:1 to 32:1
ratios). This procedure includes the
“Free Run” Calibration above, plus a
Ratio and Torque “Dyno” test.
Part-1 Free Run Calibration:
Follow steps
a.
-
c.
below to perform the
Part-1 Free Run calibration procedure:
a.
Preselect ratio of the handpiece, using
the Ratio Up/Down buttons on the console
keypad.
IMPORTANT:
This step must be
performed prior to calibrating each
handpiece.
NOTE:
The System supports
reduction handpieces with ratios ranging
from 4:1 to 32:1. Prior to calibrating any
reduction handpieces within this range,
preselect the 20:1 (
Implant Mode
), or 8:1
(
Endo Mode
), ratio setting.
b.
Insert a file, bur, drill, or the calibration
adapter (for reduction handpieces only) into
the handpiece, as shown in Figure 8.
level reaches 75% and 100% of the Auto-
Stop limit. Auto-Stop is the suggested
mode when tapping and threading
implants.
b.
MAX Torque Mode
- Depressing the
MAX (“A-S/ MAX”) button until the amber
LED illuminates will set the torque limit to
its maximum level. The handpiece will only
oper-ate up to this manufacturer-specified
torque level. The handpiece will stop and
then restart once the load is removed.
CAUTION:
Because of the unrestrained
torque characteristics inherent in MAX
Torque Mode operation, it is recommended
that MAX Mode be used only when doing
an osteotomy. It is also recommended that
the user perform a complete calibration of
the handpiece before operating in MAX
Mode and/or adhere to the torque
recommendations of the handpiece
manufacturer.
c.
Torque Limit Mode
- Depressing the
Torque Modes (“A-S/MAX”) button until
neither the green nor amber LED is lit will
enable Torque Limiting. In this mode, the
handpiece will only operate up to the
torque limit set via the Torque Up/Down
buttons. The handpiece will slow down
when a load greater than the torque limit is
applied. Once the load is removed, the
handpiece will return to target speed. This
is the only Torque Mode available for
increaser handpieces.
6.
Turn irrigation pump ‘ON’ (green LED
illuminates) and select the irrigation flow
rate for the handpiece using the “FLOW”
Up/Down buttons.
7.
Select the desired forward or reverse
direction for the handpiece using the
“FWD/REV” button (green/amber LED will
illuminate).
8.
Depress footswitch to activate the motor/
