(See Figure J.)

Saw has come to a complete stop before removing the workpiece.
11. Lock down the Saw with the Swing Lock Handle (81) and store the Saw in a dry,
safe location.
INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Always make sure the Power Switch (74) is in its “OFF”
position, and unplug the Power Cord (65) from its 120 volt electrical outlet
before performing any inspection, adjustments, maintenance, or cleaning.
2. Before each use, inspect the general condition of the Cut-Off Saw. Check for
loose screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, loose, cracked, or bent Cut-Off Wheel (57), 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.
3. Daily: With a soft brush, cloth, or vacuum, remove all dust and debris from the
Cut-Off Saw. Then, use a premium quality, lightweight machine oil to lubricate all
moving parts, except the Cut-Off Wheel itself.
4. To replace the Motor Carbon Brushes: It may become necessary at some-
time to replace the
two Carbon Brushes (29) when the Motor performance de-
creases, or stops working completely. The Carbon Brushes are located on
each side of the Motor Housing (27). To do so, use a standard screwdriver (not
included) to remove the two Carbon Brush Caps (28). Then, remove the two
Carbon Brushes from the Brush Holders (30). If the Carbon Brushes are worn
down more than 1/2 of the original size, 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 Carbon Brush Caps with a screwdriver and
tighten firmly.
NOTE: New Carbon Brushes tend to arc or spark when first used
until they
wear and conform to the Motor’s Armature.
