INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Always make sure the Switch Lever (25) is in its “OFF” position, and
unplug the Power Cord from its 120 volt electrical outlet before performing
any inspection, adjustments, maintenance, or cleaning.
Before each use, inspect the general condition of the Miter Saw. Check for loose
screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, loose, cracked, or bent Saw Blade (51), and any other
condition that may affect its safe operation. If abnormal noise or vibration occurs,
have the problem corrected before further use.
Do not use damaged equipment.
Daily: With a soft brush, cloth, or vacuum, remove all sawdust and debris from
the Miter Saw. Then, use a premium quality, lightweight machine oil to lubricate
all moving parts.
When necessary: When the Dust Collection Bag (154) is half full, remove it
from the Miter Saw, empty, and re-attach it to the Miter Saw.
To replace the Motor Carbon Brushes: It may become necessary at sometime
to replace the two Carbon Brushes (22) when the Motor performance decreases,
or stops working completely. The Carbon Brushes are located on each side of
the Motor Housing (26). To do so, use a standard screwdriver (not included) to
remove the two Carbon Brush Caps (21). Then, remove the two Carbon Brushes
from the Brush Holders (23). 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 Car-
bon Brush Caps with a screwdriver and tighten rmly.
