A.
USE AND OPERATION OF THE CHUCKING
MECHANISM FOR RP300 HANDPIECE
When you first receive your OTG, you will see a "blank" bur already
1.
inside the chuck of the handpiece.
2. With the drill held upright (front of the drill pointing upwards). Hold the
handpiece pointing upward with your left hand. Turn or twist the set ring
clockwise towards you. It is spring-loaded and you will feel some
resistance. Turn another ¼ turn and you will hear a click or snap and the
blank mandrel or bur is released as the chuck is in the open position.
3. As you can see from the outside of the handpiece, it is made up of 4
complete sections. Your left hand should be holding the bottom two
metal sections. Now, with your right hand, take your thumb and index
finger and turn the set ring (the 2nd section of metal from the top part of
the drill). Turn the set ring clockwise until you hear it click. Once you
hear the click, your chuck is now in the open position to allow you to
remove the blank bur and change it for one of your own.
4. When inserting a bit, please leave a little space between the bottom of
the bur and the top of the chuck to be sure they are not touching each
other causing friction or hindering rotation.
5. After installing your drill bit, turn the set ring counter clockwise to lock the
drill bit in place. You are now ready to use the drill.

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 1 year). Replacement part number is #8508.
2. Keep clean from dust and grindings as best as possible.
3. Wipe handpiece only with isopropyl alcohol and avoid getting inside wet.
DO NOT use rusty or eccentric burs as this will cause excess wear on
the bearings. Follow safety speeds and precautions recommended by
the bur manufacturer. Always wear a dust mask, eye protection, and use
adequate suction or ventilation.
4. Do not drop the handpiece at any time as this may cause damage to the
bearings. In the event the handpiece is dropped, please check that the
bur is not bent and resume use carefully, checking for excess noise or
heat. If any damage, please return to manufacturer for service.
D.
PRECAUTIONS
The brushes are located in the back of the handpiece, in the
section closest to the power cord.
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. There is no user serviceable part in the equipment other than
changing the motor brushes or handpiece cord. Repair should be
referred to the manufacturer, dealer or authorized service center.
5. Do not oil, lubricate, or grease the handpiece (This will only lead to
further damage of the greased sealed bearings).
6. Do not attempt to open the collet (release bur) while handpiece is
running.
7. Do not switch forward or reverse direction until motor has completely
stopped.
