malfunction, sharpen or replace the saw blade as soon as 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. Failure 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 is equipped with carbon brushes, which wear with time. When a brush
reaches the wear limit, the motor may malfunction. If the engine is equipped with
a disengaging brush, it will automatically turn off. In this case replace both carbon
brushes. Keep the brushes clean and ensure that brushes move freely within the brush
holders.
