WARNING:
BE SURE TO TIGHTEN HEAD CAP SECURELY WITH HEAD CAP WRENCH
SO IT DOES NOT LOOSEN DURING OPERATION. OPERATING HANDPIECE
WITH LOOSE HEAD CAP COULD CAUSE PERSONAL INJURY.
•After installation, proceed with sterilizing the handpiece in accordance
with the instructions listed in Section 4 - Sterilizationof this booklet.
9.To Replace the Chuck (refer to Diagrams A & B):
•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.
•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.
•Place turbine – chuck side down – against a hard flat surface. Grip
the turbine and push down against the surface, then remove the bur.
•Grasp the back of the chuck in front of the stack of small, curved
spring washers and remove the chuck from the turbine (refer to
Diagram A).
•Clean the Spindle: Insert a pipe cleaner dampened with I.P.A. into
the spindle hole as far as possible and twist (refer to Diagram B).
•Remove pipe cleaner from spindle and wipe debris from, or trim, pipe
cleaner. Repeat until pipe cleaner comes out clean.
•Apply one drop of Impact Air 45®Autoclavable Lubricant to each of
the bearings.
•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

•Remove new chuck from package, being careful not to remove or
reposition curved spring washers. Insert end of new chuck into
turbine cartridge and push with finger until fully inserted.
•Insert the bur back into turbine by placing the turbine – chuck side
down – against a hard, flat surface. Insert a bur into the spindle
hole as far as it will go. Grip turbine, push down against the surface,
and slide the bur in completely.
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.
•After installation, proceed with sterilizing the handpiece in accordance
with the instructions listed in Section 4 - Sterilization of this booklet.
