MAINTENANCE AND INSPECTION
1.
Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of cracks
and surface defects.
Replace the depressed center wheel when it has been
worn out to about 60mm in external diameter.
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 (Fig. 7)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one having the same carbon brush No.
shown in the
fi
gure when it becomes worn to or near the
“wear limit”. In addition, always keep carbon brushes
clean and ensure that they slide freely within the brush
holders.
5. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
6.
If the supply cord of this tool damaged, it must be
replaced by a specially prepared cord available through
