Operating introduction:
  1. connect the pedal switch plug to power controller.
  2. connect the handpiece and power wire.
  3. a. depress “∣” on power switch, means connect power controller to the power, stamp the pedal switch, then the motor start to work.
           b. depress “○” on power switch, means power is closed, then the instrument stop working.
c. depress speed adjusting button “△" slowly, means increasing speed.
d. epress speed adjusting button “▽" slowly, means reducing speed.


  1. If change direction, please release pedal switch or hand movement switch first.
  2. according to operation requirement, choose different attachment (straight, angled reaming attachment, straight saw attachment, oscillating saw attachment), insert reaming head or saw blade according to drilling hole’s diameter, insert the main unit axle into handpiece hole, make sure they are match perfectly. After finishing above process, test it first, if there’s no abnormal noise, means the instrument can be used.

  1. Insert reaming head first, then the instrument can start to work.
  2. The instrument must be sterilized before using.
  3. The user must be the person who has relative technical experience or has been trained.
  4. Test the instrument before using.
    1. Do check the drill bit’s jumping before procedure performance, if it jump too big range, it can not be used. Check the drill if sharp, if not should be burnished. Reaming head and saw blade are fast consumption goods, the life is about 10 times. When the tool used to cut the object, then it should be fixed and without vibrating. If the drill bit is broken, please replace it immediately.

(Make sure the relative humidity is less than 80%, and no corrosive gas )


According to hospital’s sterilization standard, reaming head and saw blade must be autoclavable. Straight and angled reaming head, straight saw attachment, oscillating saw attachment, handpiece must be put into autoclave, sterilized by steam of formalin. After sterilization, do check first before using.
