SAFETY INFORMATION
Note: For your safety: Never turn the Bur Lock Ring while the handpiece is in operation.
OPERATIONAL SUGGESTIONS:
1.Never reverse the direction of the Micromotor while it is in operation. Possible damage to the
unit may occur. Always let the Micromotor come to a complete stop before reversing directions.
2. Do Not lock or run the Micromotor / Straight Handpiece assembly without a Prophy Angle,
Cutting Disk, Contra Angle, or Test Shaft installed. Doing so could damage the Straight Handpiece
and / or Micromotor.
3.When installing the Prophy Angle or other accessory, make sure that the Bur Lock Ring is rotated
fully in the unlocked position, otherwise the accessory can not be installed and the Straight
Handpiece will not operate.
4.Do Not change the selector switch on the front of the control box between Forward and Reverse
rapidly. Always allow the Micromotor to come to a complete stop before switching directions.
5.As this is a precision instrument, always return it to Engler Engineering Corporation for repair.
NOTE Dropping the handpiece can severely damage the Prophy Angle and Micromotor.
Important: When installing any accessory make sure that the marker lines on the Locking Ring line
up EXACTLY. If the accessory does not fit easily into the Straight Handpiece, rotate the two
halves as you may have it in the locked position.
