MAINTENANCE AND INSPECTION
CAUTION
Be sure to switch power OFF and disconnect the plug from
the receptacle during maintenance and inspection.
1. Inspecting the drill bits
Since use of an abraded drill bits will cause motor
malfunctioning and degraded effi ciency, replace the drill
bits with a new one or resharpening 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 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. 2)
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 (Fig. 3) with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
6. Keeping after use
When not in use, the Electric Power Tool should be keep
in a dry place out of the reach of children.
