MAINTENANCE
Replacing Carbon Brushes.
After considerable use, your Electric Metal Shear
may not run as well as usual. If it starts or runs slowly,
makes a grinding noise or will not run at all, the problem
may be worn Carbon Brushes. An extra set of Carbon
Brushes is included with your tool for replacement as
needed.
1.
Unplug your tool before beginning work.
2.
To examine the condition of the brushes, unscrew
each Brush Cap (43), and remove each Brush (42).
nOte:
Record the position of each carbon brush
as you remove it, so you can replace them in exactly the
same way. Carbon brushes wear into the armature. If they are replaced in a different orientation, they will
have to undergo additional wear before they again fit properly.
3. If the Carbon Brushes (42) are severely worn (less than 1/8” carbon remaining) they should be replaced.
Also, if either brush is cracked or chipped both brushes must be replaced. If they are glazed, but more
than 1/8” in length, the glaze can be removed with a pencil eraser, and the brushes reused. If they are
in good condition and more than 1/8” remains, replace the original brushes in the exact configuration
they were removed.
4. To replace a Carbon Brush (42), insert it into the Brush Holder (41) carbon end first, with the
spring end to the outside. Replace the Brush Cap (43) and tighten it by turning clockwise.
nOte:
When replacing Carbon Brushes (42), do not replace only one brush. Always replace both
carbon brushes at the same time.
5. After replacing the Carbon Brushes (42), let the tool run for 2 minutes before using it. This will allow the
Carbon Brushes (42) to wear into the Armature.
caution:
During use, do not obstruct the motor vents in the Cover (48). Obstruction may cause the
motor to overheat during use, possibly damaging the tool.
