Q: How do I clean my Midwest burs
A:
Follow instructions below:
CLEANING
Insert burs into bur block or holder this Prevents damage to the blades
while ultrasonically cleaning by preventing the blades from rubbing
or vibrating against each other. Ultrasonically clean burs in a General
Purpose Cleaner following manufacturers recommended procedure. Dry.
STERILIZATION
Dry Heat Procedure: Cycle in dry heat sterilize according to
the sterilizer manufacturer recommended procedure. DO NOT EXCEED 375°F
(190°C). Drying NOT required since there is no moisture or chemical
present to cause corrosion.
OR
Autoclave/Chemiclave Procedure:
Dip in a corrosion inhibitor 1% sodium nitrite**, prior to sterilization
cycle. Cycle according to the Manufacturers recommended procedure. DO
NOT EXCEED 375° F (190°C). Then, dry. **Sodium nitrite available from
Cottrell, 303 799-9401 or your local dealer the part number to order
is PWR 1250.
Q: I'm having trouble getting burs in or out of my handpiece. What should I do?
A:
You probably need to replace the chuck in your handpiece. If you have
a Lever or Push Button style handpiece, you will need to replace the
cartridge (turbine and chuck) as the chucks are not removable. If you
have a wrenched style handpiece, you can order a replacement chuck from
your dealer.
Q: I can't fit certain burs/angles in my straight attachment. What should I do?
A:
If you're having difficulty fitting a bur/angle into your lever style
straight attachment, the shank size of the bur/angle may exceed the
allowable range of the handpiece. The lever style straight attachment
accepts only ISO standard shank lengths (nothing larger that .0925"
or 2.35mm diameter). Many lab burs and acrylic burs have shank sizes
which exceed this limit.
Q: I can't get burs to lock into the Push Button Contra-Angle Heads. Help me.
A:
The entire Contra-Angle Sheath and Head need to be connected to your
Low Speed Motor in order to seat the burs. If you don't have the sheath
"snapped-on" to the motor, then the bur will not be easy to engage in
the head.
