Always be sure that the tool is switched off and unplugged before attempting to perform
inspection or maintenance.
After Use
Blow away dust from the inside of the tool by running the tool at an idle for a while.
Brush off accumulation of dust on the base.
Accumulation of dust in the motor or on the base may cause a malfunction of the tool.
Inspecting the Depressed Center Wheel
Ensure that the depressed center wheel is free of cracks and surface defects.
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 serious
hazard.
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.
Replacing Carbon Brushes
Remove and check the carbon brushes
regularly. Replace when they wear down to
the limit mark. Keep the carbon brushes
clean and free to slip in the
holders. Both
carbon brushes should be replaced at the
same time. Use only identical carbon
brushes. (
