wrench and chuck joint wrench for changing
collets (Wrench Set p/n HP4-993), and spare
pair of motor brushes (p/n HP8-163) as
shown at right.
Checking and
Changing Carbon Brushes
A spare set of carbon brushes is supplied
with each handpiece. They come packed in
the handpiece box. Depending on how long
the handpiece is used each day, the brushes
should be checked for wear about every 200
hours of use and replaced when the brush is
less than 1mm (1/16 ″) long.
1. With handpiece power cord disconnected
from control box, unscrew protective cap
from rear of motor by turning counterclock-
wise while gripping the handpiece body. (It
has a standard right hand thread.)
2. With small crosspoint screwdriver remove
screws and brush assemblies one at a time.
Check length of carbon brush from spring to
end of brush.
Brushes should be replaced if they are less
than 1mm long. Replace both motor
brushes with new ones even if only one
of them looks worn.

Installing/Changing Collets
Important Note: Always keep a test
bur or accessory in both collets when
changing collets.
1. The Handpiece has either a 2.35mm
(3/32 ″) or 1/8″collet installed. 2.35mm
(3/32 ″), 1/8″ and 3mm collets are available
separately. They can be installed with the
collet changing wrenches, described below.
Caution: Finger tightening is not enough.
A wrench MUST be used to tighten the
collet fully several turns beyond the
point of initial resistance. If collet is too
loose or absent, the spindle will not turn
and it will damage the motor.
A bur or test bur MUST be in the
collet when changing collets!
2. With a test bur in the collet, turn the
Locking Ring toward the secure “S” (closed)
position. Do NOT remove the locking
ring or spring!
3. Place the Chuck Wrench hook into the
notch on the H.MH-130 handpiece nose
cone and unscrew it counterclockwise (see
photo above). Do NOT remove
the locking ring or spring.
