1. Cleaning

Disconnect the handpiece from the tube. Clean off the cutting debris in running water with a soft brush and then wipe off the water.

Clean the spray hole with the spray hole wire provided.

After cleaning, use the syringe or an air blow gun to get rid of any moisture left inside the handpiece.

2. Disinfection

Wipe the entire handpiece with a piece of gauze dampened with Ethanol for Disinfection (ethanol 70 to 80 vol%).

Put a little ethanol on a cotton swab and stick it in the connection end of the handpiece. Genttly wipe the ligh guide with it.

Gently wipe the light guide with a cotton swab.

When using the high-temperature washer disinfector, observe our specified conditions attached to the product.

3. Lubrication

Before autoclaving, make sure that you lubricate and clean the handpiece with the AR SPRAY or MORITA MULTI SPRAY.

Push the lever on the spray nozzle up in the direction of the arrow. Cover the head of the handpiece with gauze, insert the chuck spray nozzle tip into the bur hole, and then spray for 2 seconds.

Push the lever on the spray nozzle down in the direction of the arrow. Insert the nozzle into the connection end of the handpiece, hold it firmly and then spray for 2 seconds.



Connect the handpiece to its tube.
Operate the handpiece for at least 15 seconds to expel excess lubricant from the head and then wipe it off with a piece of gauze.

5. Packaging

Place the handpiece in a sterilization pouch.

Do not use any sterile pouches that contain hydrosolube adhesive ingredients such as PVA (polyvinyl alcohol). Otherwise, its adhesive ingredient may elute, seep inside the handpiece during the sterilization, resulting in a solid residue and a failure to rotate properly.


6. Sterilization

Autoclave the handpiece. After the autoclaving, store the handpiece in a dry environment.
Recommended autoclaving conditions: 134°C (273.2°F) in a sterilization pouch for at least 5 minutes
