MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of a dull tool will cause motor malfunctioning and degraded efficiently, whet it
or replace with a new one without delay when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened.
Should any of the screws be loose, retighten them immediately. Fail -use to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure
the winding does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes
The motor employs carbon brushes which are con -sumable parts. When they become
worn to or near “wear limit”, it could result in motor trouble. When an auto-stop carbon
brush is equipped, the motor will stop automatically. At that time, replace both carbon
brushes with new ones which have the same carbon brush Nos, shown in the figure.
In addition, always keep carbon brushes clean and ensure that they slide freely within the
brush holders.
REPLACEMENT STEPS.
The carbon brush can be removed by removing the cap cover, cap rubber and brush
cap in that order at the interior.
