MAINTENANCE
WARNING! Disconnect the abrasive cut-off saw from the AC power source
eliminating any accidental starting of the motor.
Before using the Cut-off saw, a thorough inspection should be made. Check for the
following:
1. Loose screws
!
2.Misalignment or binding of moving parts
3.Cracked or broken parts
4.Damaged electrical wiring
5.Cracked, chipped or bent Cut-off wheel.
CLEANING
Daily: Using a soft-bristled brush, cloth, or shop vacuum, remove all clippings, dust,
or other debris around the cut-off saw. Follow the cleaning instructions below using
premium lightweight tool oil and lubricate all movable parts.
WARNING! DO NOT USE MACHINE OIL ON THE ABRASIVE CUT-OFF WHEEL.
Machine oil will absorb into the abrasive material making up the wheel and
potentially weakening it causing it to break. Should the Cut-off wheel break while it is
in motion, pieces could fly off at high speed damaging the Cut-off saw, the
!
workpiece or resulting in serious injury or even death to the operator.
MAINTENANCE
The abrasive cut-off saw is virtually maintenance free. Closed-type, grease-sealed
ball bearings are used throughout the cut-off saw. These bearings are packed with
grease at the factory and should last the life of the cut-off saw. The only required
maintenance is covered in the CLEANING section above. If this particular model
cut-off saw is equipped with replaceable carbon brushes on the motor, there may
become a time they need replacing.
TO REPLACE THE CARBON BRUSHES: See (Fig.12)
1. Locate the brushes. They should be both sides of the motor housing at 180°
degrees apart.
2. Use a slotted blade screwdriver and turn the brush caps counterclockwise.
3. Remove the caps, tension springs, and carbon brushes.
4. Place new carbon brushes into the openings.
5. Place the curved end of the brush into opening first, followed by a tension spring.
6. Insert the cap and, using a slotted blade screwdriver, tighten the caps by turning
clockwise.
Fig.12
Should the carbon brushes be worn more that 1/2 the original size, replace both
brushes at the same time.. Ensure the springs operate freely and the tension doesn't
cause armature of the motor to drag or make noise.
NOTE! New carbon brushes may arc or spark until they wear slightly and conform to
!
the armature of the motor. This is a normal occurrence.
