4. FIRST USE:
- Check the content of the package to make sure you received
the attachment with accessories, user manual and a warranty
card.
- Micromotor handpiece attachment connection dimensions
conform to ISO 3964
- Use only burs and cutters that correspond to ISO 1797-1 with
shank diameter of 2.334 ÷ 2.350 mm, maximal length of 22 mm
for contra angle heads and maximal length of 44.5 mm for
straight attachments.
- Pay attention to the warnings and instructions provided by
manufacturers of burs and cutters.
- DO NOT USE burs and cutters that deviate from the indicated
data.
- DO NOT USE burs with worn shank. They could fall out during
treatment and injure the patient. Once in a while check the
sharpness of burs under a magnifying glass.
4.1. Coupling with micromotor pic. 3
Attaching: With a slight twisting motion slip the attachment
handpiece onto the micromotor coupling until the
driving and chuck mechanisms snaps into place.
Removal: Remove the attachment handpiece off of the
micromotor by a slight pull along the micromotor axis
while simultaneously twisting the attachment around.
Adjust the flow of water exiting the nozzle of the handpiece cooling
spray to min. 50 ml/min. at the inlet pressure of 200kPa. Air flow of the
cooling spray 1.5NL/min at the inlet pressure 200kPa.
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.
4.2. Attaching head to the contra angle pic. 4
(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.
- Never insert the head during rotation.
- Check the head’s proper connection with contra
angle handpiece before each use.
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
Fig.6
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.

We recommend the use of protective gloves or
another finger protection while inserting, removing
and checking the bur’s grip. This way you will avoid
injuries and infections.
5. PRODUCT MAINTENANCE
The lifetime of micromotor handpieces is extended by regular and correct
maintenance. Treat the handpiece before the first and after each
following use by the procedure of external cleaning –disinfection –
greasing –sterilization.
5.1. External cleaning
The surface of straight and contra angle micromotor attachments can be
cleaned with alcohol solution or by brushing under running water.
5.2. Disinfection
We recommend disinfecting the surface of handpiece with antiviral
disinfectants effective against HIV virus, i.e. disinfectant spray or wipes.
- DO NOT immerse attachments into disinfectant
bath. This may cause them to malfunction.
- DO NOT use high alkaline or chlorine based
disinfectants.
-DO NOT clean or disinfect attachments in ultrasonic
bath.
5.3. Greasing
Before each sterilization or at least twice a day, grease the handpiece by
overspraying for 1-2 seconds, pic. 7. Place the handpiece with the
header down that the residue oil could leave through the header out,
wipe the excess oil. If you see black oil flowing from the handpiece,
repeat the process until the flowing oil is clean. When handling, use a
pulp that is well visible for dirt.
It is recommended to treat the bur clamping system once per week.
Spray into the bur hole with spindle applicator tip for 1-2 seconds (Fig.
8).
- For maintenance of straight and contra angle attachments use only
SMIOIL spray.
5.4. Sterilization
Micromotor handpiece attachments are autoclave sterilizable up to 135oC.
Suggested verified parameters: temperature 134oC, Time 5 min.,
Pressure 300 kPa, three times pre-vacuum. We recommend use of
equipment according to EN 13060: 2004 Type B, packaging according to
EN 868-5: 2009.
- Also sterilize the needle T07026034
- Treat the handpiece attachments with SMIOIL spray before each
sterilization
- Autoclave only cleaned handpiece attachments
- Do not sterilize handpiece attachments with inserted burs.
- Follow the autoclave manufacturer instructions and national legislations.
- Remove the handpiece attachments from autoclave immediately after
sterilization cycle ends.
If handpiece attachments have not been used for a prolonged
period of time, it is necessary to clean and maintain them
according to the user manual.
Store handpiece attachments in a dry place.
If you hear irregular sounds during the operation, feel strong vibrations or
if the bur cannot be clamped, stop using the handpiece attachment and
immediately contact a Chirana authorized dealer or CHIRANA Medical,
Inc. to avoid further damage to the product.
