7.Operation
•When attaching a standard handpiece to the coupling, be sure that all
tubes are fully inserted with the gasket flush to the connector and
maintained in position prior to tightening the coupler sleeve/nut onto
the handpiece.
•A Quick Disconnect handpiece is designed to connect to one of our
Quick Disconnect Couplers, Item #627, #628, and #629. The Quick
Disconnect handpiece is designed to also fit the KaVo Multiflex coupler
(KaVo is a registered trademark of KaVo Dental GmbH, Biberach,
Germany ). Insert the Quick Disconnect handpiece onto the appropriate
Quick Disconnect Coupler until it snaps securely into place.
•NEVER force a handpiece onto an incompatible coupler.
•NEVER depress the head cap button (the chuck release) while the
handpiece is running.
•Do not use the handpiece if an air leak is detected from the front
(bur end) of the head.
•NEVER operate the handpiece without an adequate water or saline
supply at the cutting site as cutting and cooling efficiency will be reduced.
TO CHANGE BUR:
•To remove a bur: Press the head cap button (the chuck release)
firmly and withdraw bur from spindle.
•To insert a bur: Slide bur in as far as it will go (approximately
halfway), then press the head cap button (the chuck release) firmly
and slide bur in the rest of the way.
•Test the bur for security by tugging the bur with your fingers.
8.To Change the Turbine (refer to Diagram A):
•Make sure a bur is in place prior to disassembly.
•Fit the head cap wrench, provided with the handpiece, into the slots
of the head cap. Turn the wrench counter-clockwise to loosen and
unscrew the head cap.
•Remove turbine from head. If turbine stays with head cap, separate
these two parts with a gentle pull.
•If turbine does not come out with head cap removal, push turbine
out through the rear, using the bur.
•
NEVER operate the handpiece without an adequate partition in the throat,
or dental dam, to prevent ingestion or aspiration of dental materials.
•INSPECT interior of head carefully to ensure that all turbine
components, such as the two washers and the front, blue O-ring,
have been removed. Clean interior of the head with Isopropyl Alcohol
(I.P.A.) using a bristle brush and/or swab. After cleaning, ensure that
the interior of the head is dry, clean and free of debris.
•Clean the Head Cap : Prior to cleaning, inspect the head cap to
ensure that the turbine’s rear, black O-ring has been removed. If it
is present, carefully remove the O-ring. Using I.P.A. with a bristle
brush and/or swab, clean the head cap. Ensure that the head cap is
clean and dry.
•Remove the turbine, the two washers, and the two O-rings from the
Turbine Kit bag.
•Apply one drop of Impact Air 45®Autoclavable Lubricant to each of
the bearings of the new turbine.
•Slide the rear, black O-ring onto the rear bearing.
•Slide the front, blue O-ring onto the front bearing (bur end).
•Slide the two washers, in either order, onto the bur end of the
turbine, flush against the front bearing.
•Lubricate the head cavity with Impact Air 45®Autoclavable Lubricant.
•While holding the turbine with the bur end facing upward, carefully
insert the turbine assembly completely into the head with gentle
pressure.
•Push turbine into the interior of the head using the bur to guide it
into the center of the hole. As the turbine begins to seat, apply firm
pressure with a wobbling motion to seat the front, blue O-ring. The
end of the rear bearing should be flush with the open end of the
head chamber.
•Using your fingers, carefully screw the head cap back onto the rear
of the head and tighten with the head cap wrench. Do not force the
- 9 -
head cap. If resistance is experienced, connect handpiece to your air
source. Thread the head cap on approximately half way. Feed air
through the handpiece, being careful to maintain a grip on the cap.
Tighten the cap while handpiece is running. If the turbine slows,
manipulate the cap back and forth to increase the speed. Continue
this process until head cap is snug and tighten completely with head
cap wrench.
