Collet Chuck Cover - Use the collet chuck wrench to remove the cover. The collet chuck is located under this cover.
Spindle Assembly - This housing covers the spindle shaft. The spindle shaft includes the motor shaft and collet chuck assembly.
Collet Chuck Lock - This lock has two positions. With the bur pointed away from you, rotate the chuck lock counter clockwise to the R position to release the bur. The bur can then be removed or replaced. Rotate the lock clockwise to the S position to secure a bur in place.
Carbon Brushes Compartment - Unscrew the compartment cover to access the carbon brushes. Carbon brushes should be changed routinely, at least once a year
or every 1,000 hours of use. See “Changing the Carbon Brushes” on page 10.
Cautions
Please read the following cautions carefully before operating your new OmniDrill.
Work Area
• Do NOT work in a dangerous place. Keep the workplace clean. Debris may cause an accident.
• Do NOT use the control box in a humid place.
WEAR PROPER PROTECTIVE CLOTHES AND EQUIPMENT, INCLUDING A
DUST MASK AND SAFETY GOGGLES. USE A PROPER SUCTION UNIT
AND A VENTILATOR.
Operation
• Use the handpiece and foot pedal with the control unit only.
• Do NOT drop the handpiece. It may be damaged or broken. If it is dropped, verify that the bur is not bent and that no excessive heat is generated during normal drill operation.
World Precision Instruments 3
• Check for any troubles, including excessive vibration of bur, at low speed, and then start high speed.
• Ensure that the handpiece comes to a complete stop before setting it down or changing motor direction.
Bur and Chuck
• Turn off the power and disconnect the handpiece when changing the bur.
• When the chuck is locked, the maximum projection length of the bur should be less than 35mm.
• Use a bur that conforms to ISO standards.
• Keep a bur in the handpiece collet chuck after operation.
• Do not open the chuck while operating.
• Avoid using a rusty or bent bur that may cause excessive wear of bearings.
Refer to the safety recommendations (operating speed and precautions) for the bur ( Fig. 3).
Fig. 3–Recommended maximum RPM/bur diameter.

Power
• Do not turn on the power while the collet chuck of the handpiece is open. The motor could short circuit.
• To avoid an injury caused by a sudden start, verify that the switch is off before putting the power plug in the wall socket (mains).
• A circuit breaker is provided to protect the motor. It is activated when there is an overload the motor will not tolerate.
• Unplug the power cord before disconnecting the control box.
• Set the correct voltage on the control box and use an appropriate fuse.

SETUP INSTRUCTIONS
1. Verify that the control box power switch is off ( 0).
2. Plug the power cord into the wall outlet (mains).
3. Connect handpiece to the motor connector port of the front of the control box.
4. Set the speed dial on the control box to the zero position (fully counterclockwise).
5. Verify that the chuck lock of the handpiece is locked. If the bur does not pull out easily, the chuck lock is in the secure position. If not, secure it. To secure the chuck lock, point the bur away from you and rotate the chuck lock clockwise to the S position.
6. Hold the handpiece with one hand, and with the other hand turn on the power to the control box.
7. Verify that the handpiece is running normally using the speed control dial on the front of the control box.
8. Turn off the power and connect the foot pedal to the foot pedal connector on the back of the control box.
9. Check the operating speed of the pedal. With the power switch in the off (0) position, press the pedal and slowly increase the speed using the speed control dial.
10. Turn off the power and switch to the reverse direction using the Forward/
Reverse switch on the front of the control box.

OPERATING INSTRUCTIONS
Changing the Bur
1. To release the chuck lock, point the bur away from you and rotate the chuck lock counter clockwise to the R position. When you hear a click, the collet chuck is open.
2. When the chuck is opened, remove the bur.
3. Insert the desired bur.
4. To secure the chuck lock, point the bur away from you and rotate the chuck lock clockwise to the S position. When you hear a click, the collet chuck is closed and the bur is secured.
Normal Operations
1. Install the desired bur in the handpiece collet chuck, and verify that the chuck lock is in the secure position. See Changing the Bur, above. Do not turn the
OmniDrill on until the bur is secured.
2. If desired, the OmniDrill can be mounted in WPI’s stereotaxic frame ( Fig. 4) using the OmniDrill Mounting Probe for Stereotaxic Frames (WPI # 502237).
Fig 4.–OmniDrill35 mounted in a WPI stereotaxic frame
3. If you are using the foot pedal, set the power switch to off (0). Otherwise, turn the power switch to on (1). When the power is on, the power light (PL) illuminates.
4. Adjust the speed control dial on the front of the control box to the desired speed.
5. Use the OmniDrill to polish, cut or drill.

MAINTENANCE
• Keep the area around in handpiece free of dust and grindings.
• Remove dust from the exterior of the handpiece by wiping it with a cloth moistened with isopropyl alcohol. Avoid getting moisture on the inside of the
OmniDrill.
• Do not apply oil to the OmniDrill or clean it with water. Oil could break down the grease inside the bearings.
• Air cleaning is acceptable, but air pressure may affect the handpiece or motor.
Replacing a Fuse
The fuse is in a small fuse holder beside the power cord on the back of the control box.
Fig. 5–Fuse holder
holder
Fig. 6–Use a screwdriver to remove fuse
1. Insert a regular (flat head) screw driver into the slot on the fuse holder and rotate counter clockwise a quarter turn to open the fuse holder.
2. Pull out the fuse holder, and replace the fuse (WPI # 504458-5 or 503560-5) with a new one (120V-T3.15A/250V or 230V-T2A/250V) ( Fig. 7).
Fig. 7–Remove fuse. Fig. 8–Fuse and holder
3. Reinsert the fuse and fuse holder. Line up the two tabs on the fuse holder with the fuse holder on the control box. Using the screwdriver, gently push the fuse holder back into the fuse holder and turn a quarter turn clockwise to secure it.

Changing the Carbon Brushes
A replacement set of carbon brushes has been provided with your OmniDrill. To prevent damage to the motor, periodically check the carbon brushes for wear. The motor can be damaged if worn carbon brushes are not replaced in time. Carbon brushes wear like a pencil eraser and should be replaced after about 1,000 hours of use. These brushes should be replaced before the wear reaches the tiny hole on one side where the copper spring is attached to the carbon brush ( Fig. 9).
Do
NOT
wear brushes past indicator hole
Fig. 9–Indicator located at the
top of the carbon brush
CAUTION: Verify that the power is off and the control box is unplugged before changing the carbon brushes.
1. Turn off the power on the control box and unplug the power cable.
2. Unscrew the carbon brushes compartment cover at the base of the handset to expose the carbon brushes ( Fig. 10). There is a carbon brush on either side of the OmniDrill, and they should be changed at the same time.
Fig. 10–Use a screwdriver to remove carbon brushes Fig. 11–Carbon brushes
3. Use a small Phillips head screwdriver to remove the two screws holding the carbon brushes.
4. Use a pair of tweezers and gently remove the used carbon brushes. Pull them straight up.
5. Put the screws in the holes of the new carbon brushes (supplied with your
OmniDrill) and insert the new brushes the same way the old ones came out.
Line up the screws with the screw holes and gently compress the spring as you position the new carbon brushes. Hold it in place while you tighten the screw.
6. Reposition the carbon brushes compartment cover and screw it into place.
7. IMPORTANT: Run the motor for one minute with no load in order to break in the brushes correctly.
