MAINTENANCE AND INSPECTION

1. Checking punch and die
A worn or defective punch and die will greatly decrease
work effi ciency.
Check and replace them periodically. Refer to "Replacing
punch and die".
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
brushes with new ones 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 ensue that they slide freely within the
brush holders.
5. Replacing carbon brushes (Fig. 7)
Disassemble the brush cap with a screwdriver. The
carbon brush can then be easily removed.
6. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to HiKOKI Authorized Service Center for the
cord to be replaced.
