Replacing Carbon Brushes
Replacement Carbon Brushes
SKU: 5105094
1. Be sure to replace both brushes at the
same time. Replacement of only one
carbon brush will cause motor damage.
2. To replace worn brushes, unscrew
the Carbon Brush Housing Cover in a
clockwise direction (Fig. 7).
3. Using a small Phillips Screwdriver,
unscrew each brush assembly.
4. The brush tension spring will push the
assembly out of the brush well so it can
be lifted clear.
5. The two new Carbon Brushes should be
installed by gently pushing them into the
brush well.
6. Screw the assembly in securely, and
replace the Carbon Brush Housing Cover
Expected brush life is 800–1,000 hours. Worn brushes should be replaced
when the handpiece no longer runs at maximum speed or sounds as though it
is “running out of gas.”

Safety Precautions
Read all safety precautions thoroughly to ensure proper and safe use.
Safety Precautions Suggestions
Set Voltage Selector
Switch
Before operating, be sure that the Voltage Selector
Switch is set to the voltage you will be running the unit
from.
Suggested
Temperature and
Environment
Suggested temperature range: 32–104°F (0–40°C).
Avoid use in dusty, warm, or humid environments to
prevent controller damage.
F/H Switch Make sure you have the F/H Switch on the proper
mode based on intended use.
Clear Controller
Ventilation
Ensure the Controller Ventilation Vents on the back of
the unit are not obstructed.
Prevent Stalling and
Damaging Motor
Ensure the Collet Release Ring is in the secure “S”
position before operating the handpiece. Operating
with the ring in the “R” release position may stall the
motor and cause damage.
Prevent Damage To
Motor
Avoid altering tools or rotating the Collet Release Ring
during handpiece operation, as it may cause the motor
to abruptly stop which can result in damage to both
parts and the motor itself.
Prevent Carbon
Brush and
Motor Armature
Commutator Wear
Avoid stalling the motor by pushing too hard on the
workpiece or exceeding the torque capacity of the
handpiece motor. This will cause excessive carbon
brush and motor armature commutator wear.
Do Not Exceed Max
RPM
Do not exceed the maximum rotation speed (RPM)
specied by the manufacturer/distributor of the
tool being used and adhere to the safe/ maximum
operating speeds.
Check Proper Shank
Size
Handpiece Collets are manufactured to close
tolerances. Use tools with a shank size that
corresponds to the Collet being used.

Bending
Insert a tool fully into the Collet until it bottoms at the
back of the Collet. Using a tool not fully inserted is
dangerous and can cause the tool to vibrate or the tool
shank to bend.
Tool Precaution Never use tools out-of-round or with bent shanks.
Consistently Tighten

Periodically check to see that the Collet is fully
tightened. A loose Collet will cause the handpiece to
run slower.
Do Not Use Water
or Oil to Clean
Handpiece
Avoid using the handpiece in water or oil and keep
foreign matter out of the inner casing. This includes
dirt and excessive wood dust. Failure to do so may
