Maintenance = To check 3 following things.

① Check the condition of the blade, anchor, and screw.
② Clean inside the horn.
③ Tighten the screws to 0.6 N·m.

If the above three points are neglected, the machine may malfunction.

Following things are explained on the movie above, how to do it.

① Check the condition of the blade, anchor, and screw.

If any part is broken or dirty, the ultrasonic cutter will mistakenly detect it as a load and increase the power, causing the machine to automatically stop or even break down.

（Solution）
Replace any broken or dirty parts with new one.

② Clean inside the horn.

Similarly, if the inside of the horn (where the fixing device is set) is dirty, the ultrasonic cutter will mistakenly detect it as a load, causing the power to increase, leading to the machine automatically stopping or even breaking down.

（Solution）
Use a cotton swab or maintenance sets to clean the inside of the horn.
※Never wipe with water.

Introduction	3 abrasive papers + 1 cleaning bar	10 abrasive papers
How to use	Place the abrasive paper on the maintenance rod and wrap it around the bar (silver) with the abrasive paper side facing outwards. Insert the bar with abrasive paper deep inside the horn and turn the rod to rub the dirt off the inside wall. Replace the abrasive paper with new one when it becomes contaminated or torn.	After you get “cleaning bar” (SB01), please get only SB02. Only abrasive papers will be kept consume after using it.

③ Tighten the screws to 0.6 N·m.

The screws that fasten the blade and fixture must be tightened to 0.6 N m. If they are tightened too much or too little, the cutter will malfunction.

（Solution）
Use the “Torque screwdriver set ZH25T2” or the hex wrench RR02 that comes standard with the machine to tighten the screw to 0.6 N·m.
