4.2. Attaching head to the contra angle
168 D-T
168 D
(Does not apply for 110D, 120LB, 120LR) Rotate the clamping ring of
contra angle in the direction of the arrow until it stops and hold it in
position. Insert the head into the contra angle so the grooves on the head
match the slots inside the contra angle. Release the clamping ring.
4.3. Straight handpiece bur insertion and replacement
pic. 5
The bur gripping mechanism is released by rotating the clamping ring in
the indicated direction. Reverse rotation will tighten and lock the inserted
bur.
4.4 Bur insertion and replacement on 120LB, 120LR contra angles
Inserting the bur - press the push button firmly with your thumb and
simultaneously insert the bur all the way into the hole. The correct
clamping position of latch burs is found by rotating the bur around its axis
(applies for 120LB). To remove the bur - press the push button with your
thumb and pull the bur out. After each change of the drill it is necessary
to check its clamping by pulling it outwards from the head.
Minimum requirement for the cooling air supplied by
micromotor is 6 NL/min.
Insufficient cooling can increase the temperature of
external parts.
DO NOT attach or remove any handpiece
attachments from the micromotor while it is running.
