2. Inspecting the carbon brushes (Fig. 35 and Fig. 36)
The carbon brushes in the motor are expendable parts. If the carbon brushes become excessively worn,
motor trouble might occur. Therefore, inspect the carbon brushes periodically and replace them. Check
the carbon brushes after the first 50 hours of use for a new machine or after a new set of carbon brush
have been installed. After the first check, examine them after each about 10 hours of use until such time
that replacement is necessary.
When the carbon on either brush is worn to 3/16" (5 mm) in length or if either spring or shunt wire is
burned or damaged in any way, replace both carbon brushes (see Fig. 35). If the carbon brushes are
found serviceable after removing, reinstall them in the same position as before removed. Also, keep the
carbon brushes clean so that they will slide smoothly within the brush holders. The carbon brushes can
easily be removed after removal of the brush caps (see Fig. 36) with a slotted (minus) screwdriver.

3. Inspecting the mounting screws
Regularly inspect each component of the power tool for looseness.
Re-tighten mounting screws on any loose part.
WARNING:To prevent personal injury, never operate the power tool if any components are loose.
4. Inspecting the saw blade guard for proper operation.
Before each use of the tool, test the saw blade guard (see Fig. 1) to assure that they are in good condition
and that they move smoothly. Never use the tool unless the saw blade guard operates properly and
unless they are in good mechanical condition. Ensure the anti-kickback pawls are always sharp so they
dig into the workpiece to help prevent kickbacks. If any damage has occurred, repair it promptly.
5. Frequently clean the saw blade guard.
Wipe off saw dust attached to the inside of the see-through saw blade guard using a soft cloth. Do not
use solvent (gasoline, thinner etc.), solvents will damage plastic parts.
6. Storage
Confirm that the switch is turned OFF, that the power plug has been removed from the receptacle and
that the safety key has been removed and has been in a secure place, after operation of the tool has been
completed. When the tool is not in use, keep it stored in a dry place out of the reach of children.
7. Lubrication
Lubricate the following moving parts and rotating parts once a month to keep the power tool in good
operating condition for a long time (see Fig. 1 and Fig. 2). Use of machine oil is recommended.
Oil supply points:
Rotary and moving portion of wheel
8. Cleaning
Periodically remove chips and other waste material from the surface of the power tool with a damp,
soapy cloth. To avoid a malfunction of the motor, protect it from contact with oil or water.
