3. TOOL LUBRICATION: Always check the oil level of the Circular Saw before
each use. To check and add oil, make sure the Circular Saw is sitting on a flat,
level surface. Remove the Oil Plug located at the front of the Circular Saw. The
oil level should never be below the bottom threads of the Oil Plug Hole. When
adding oil, fill with a 5 to 10 Weight Worm Drive Lubricant until the oil begins to
run out of the Oil Plug Hole. Then, replace the Oil Plug. NOTE: With a new
Circular Saw, change the oil after the first ten hours of use. (See Figure J.)

4. CARBON BRUSHES: To maintain peak efficiency of the Circular Saw’s Motor it
is recommended that every two to six months the Carbon Brushes (part #71) be
examined. The Carbon Brushes should be free of dust and dirt. The Carbon
Brushes should be replaced when they have worn down to 3/16” in length. The
Carbon Brushes should slide freely in and out of the Brush Holders (part #70)
without sticking. To check the Carbon Brushes, remove the Brush Holder Cover
(part #72) located on each side of the Circular Saw. Lift out the Carbon Brushes
to inspect. If cleaning is necessary, rub the Carbon Brushes thoroughly with a
pencil eraser. Next, clean the Brush Holder openings with compressed air or a
clean cloth. Then, replace the Carbon Brushes and Brush Holder Covers. If
replacement is necessary, make sure to replace both Carbon Brushes at once.
