3. 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 when they have become worn to
the wear limit line as shown in Fig. 35.
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.
4. About Handling the Motor (see Fig. 1)
Winding of the motor is said to be the heart of this tool. Exercise utmost caution not to damage the
winding by exposing it to wash oil or water.
NOTE:
Accumulation of dust and the like inside the motor can result in a malfunction.
After using the motor for 50 hours or so, carry out no-load running, and blow in the dry air
from a wind hole at the motor's rear. Such action is effective to discharge dust and the like.
5. Inspecting the screws
Regularly inspect each component of the power tool for looseness.
Re-tighten screws on any loose part.
