INSPECTION, MAINTENANCE, AND CLEANING

Caution:

Always disconnect the Cut-Off Saw from its electrical power supply

source before performing any inspection, maintenance, or cleaning.

2. Before each use, inspect the general condition of the Cut-Off Saw. Inspect the

Power Switch, Power Plug, Cord assembly, and extension cord (if used) for dam-

age. Check for a cracked or damaged Cut-Off Grinding Wheel, improper mount-

ing of a Cut-Off Grinding Wheel, loose screws, broken parts, misalignment, or

binding of moving parts, and any other condition that may affect its safe

operation. If abnormal noise or vibration occurs, turn off the Cut-Off Saw

immediately and have the problem corrected before further use. Do not use

damaged equipment.

3. The Cut-Off Saw features

two

Carbon Brushes (27) which, periodically, should be

examined for wear. The Carbon Brushes are located on the Right Housing (22)

and Left Housing (44). To inspect or replace the Carbon Brushes, use a small

standard screwdriver to remove the Brush Covers (26). Remove the Carbon

Brushes from the two Brush Holders (28), and examine the concave surface of the

Carbon Brushes. The surface should be smooth and clean. If the Carbon

Brushes appear only dirty, they may be cleaned by rubbing them with a pencil

eraser. Make sure to remove any eraser dust which may have occurred during

cleaning. If there are large scratch marks in the Carbon Brushes, or parts of the

Carbon Brushes have broken off, replace

both

Carbon Brushes immediately with

approved replacement Carbon Brushes from Harbor Freight Tools. To reinstall the

Carbon Brushes, insert them into the Brush Holders. Turn the Carbon Brushes

vertically so they will fit into the Brush Holders. Then, replace the Brush Covers.

(See Assy. Diagram.)

4. With a brush, soft cloth, or vacuum, remove all debris from the Cut-Off Saw.
