Removing worn brushes
– cont’d
NOTE:
Pay attention to the position of the
braided copper brush wire (8) (Fig. 8). When the
new carbon brush is reinstalled, the braided
brush wire MUST be placed in exactly the same
position.
3.
Use a small slot screwdriver to lift the end
of the coil spring (4) upward and place it on
the edge of the copper brush holder (5).
4.
Use small needle nose pliers to pull the top
spade connector (6) from the spade
terminal.
5.
Turn the two brush holder screws (7)
counter clockwise about 4 turns using a
#2 screwdriver.
NOTE:
Do NOT completely remove the
screws. Back the screws out only far
enough to allow the carbon brush to be
removed from the brush holder.
6.
Carefully grasp the braided copper brush
wire (8) and lift the carbon brush (9) from
the brush holder.
INSTALLING NEW MOTOR BRUSHES
7.
Once the old carbon brush has been
removed, use a SOFT DRY brush to
carefully remove all grinding dust from the
brush holder and install the new carbon
brush in the reverse order that was used to
remove the worn carbon brush.
8.
Reinstall the new carbon brush in reverse
order of paragraphs 1 through 6.
NOTES:
a)
Make sure the braided brush wire is routed
EXACTLY the same as the original.
b)
Make sure the end of the coil spring is
placed on top of the carbon brush (Fig. 8).
9.
Turn the tool over to remove and replace
the second carbon motor brush using the
same procedures noted above.
10. Once both carbon brushes have been
replaced, reinstall the motor end cap and
the motor end cap screws.
