Maintenance and inspection
1.
Inspecting the tool
When using dull tool bits this can cause motor malfunction and degraded efficiency.
Always replace dull bits with new ones 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. Failure to do so could
result in serious injury.
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.
Two carbon bushes are provided.
The motor employs carbon brushes that are consumable parts; when an excessively
worn carbon brush could result in motor trouble, replace the carbon brush. The carbon
brushes must be only replaced by a qualified service. Wear limiter (6) No of carbon brush
