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. Inspecting the carbon brushes (Fig. 10).
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush could result in motor trouble, replace a carbon
brush with a new one 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.
4. Replacing a carbon brush.
Disassemble the brush cap with a minus-head
screwdriver. The carbon brush can then be easily
removed.
5. 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.
6. Lubrication (Figs. 1 and 2)
Feed oil at the oiling points once a month for
extending machine service life (machine oil is
suitable for the machine).
