3. Daily: With a soft brush, cloth, or vacuum, remove all dust and debris from the
Miter Saw. Then, use a premium quality, lightweight machine oil to lubricate
all moving parts except the Saw Blade (4).
4. To replace the Motor Carbon Brushes: It may become necessary at some-
time to replace the
two Carbon Brushes (26) when the Motor performance de-
creases, or stops working completely. The Carbon Brushes are located on
each side of the Motor Housing (31). To do so, remove the two Brush Holder
Caps (23). Then, remove the two Carbon Brushes from the Brush Holders (25).
If the Carbon Brushes are worn down more than 1/2, replace
both Carbon
Brushes. If, however, the Carbon Brushes are just dirty they may be cleaned by
rubbing them with a pencil eraser. When installing the Carbon Brushes, make
sure the carbon portion of the Carbon Brushes contact the Motor Armature, and
that the springs face away from the Motor. Also, make sure the springs operate
freely. After cleaning or replacement, replace the Brush Holders.
NOTE: New Carbon Brushes tend to arc or spark when first used
until they
wear and conform to the Motor’s Armature. (See Assy. Diagram.)
5. NOTE: With the exceptions of Steps #1, #2, #3, and #4 all other mainte-
nance and servicing should be performed
only by a qualified service tech-
nician.
