MAINTENANCE AND INSPECTION
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
reduced cutting e
ffi
ciency and may cause overloading of
the motor. Replace the blade with a new one as soon as
excessive 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. 11)
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. 11)
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
