Operating Instructions

Instruction No. INS271

110-4105 Micro Drill System
  1. The Handpiece cord plugs into the lower left socket on the control box.
  2. The Foot pedal plugs into the socket on the back of control box.
  3. Plug the power cord into an electrical outlet. Make sure the outlet is properly grounded and compatible to the voltage input requirement.
    Note: Check the power switch setting on the back of the Control Box to be sure it is set at the proper voltage, either 110 volts or 230 volts.
  4. Turn the power switch to the "ON" position.
  5. The Forward/Reverse (L/R) DIRECTION switch is located at the bottom right of the Control Box. Normal operation is in R, or clockwise direction.
  6. The Handpiece is now ready for operation. The speed of the motor is set with the control knob by turning it clockwise.
    Note: The handpiece should always be on the rubber stand when not in use to avoid dropping or rolling.
  7. Depress the foot pedal and gradually turn the speed control knob clockwise until the desired speed is attained.
Handpiece Collet
  1. To open/release the collet, turn in clockwise direction. The collet release is spring loaded. You will feel the spring get harder to turn as you twist and then a click or snap will be felt as the chuck release opens. Turn counterclockwise to close/secure.
    Note: Collets are available in either 3/32", and 3mm or 1/8".
  2. It is normal for the handpiece to warm up slightly on continued use. Do not expose to water or use in wet locations.
Changing Handpiece Collet
  1. Turn set ring clockwise to open the chuck.
  2. Using the chuck wrench tool included with the handpiece, place the triangle section of the wrench over the top of the chuck turning counterclockwise until the chuck is completely unscrewed and is loosened from the spindle.
  3. Insert a different size chuck or replacement chuck. Use the chuck wrench tool with the triangle section over the top of the chuck and turn the wrench tool clockwise until the chucks is completely tightened.
  4. If final adjustment of the chuck is needed, turn the wrench tool approximately 1/4 turn counterclockwise to loosen the chuck.

Suggested Maintenance
  1. Carbon brushes in the handpiece motor are designed for long life, approximately 1,000 hours. Carbon brushes should be replaced periodically, approximately once each year.
  2. Wipe handpiece only with isopropyl alcohol and avoid getting wet.
  1. When using electric tools, use basic safety precautions in order to reduce risk of fire, electric shock and personal injury.
  2. Do not expose electric tools to water or use in damp or wet locations.
  3. Do not wear loose clothing or jewelry as they can be caught in the drill.
  4. Do not attempt to service or repair the handpiece, control box or the foot pedal. Repair should be referred to the manufacturer, dealer or authorized service center.
