MAINTENANCE AND INSPECTION
1. Inspecting the saw blade
Since use of a dull saw blade will degrade e
ffi
ciency and cause possible motor malfunction,
sharpen or replace the saw blade as soon as 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. Inspecting the carbon brushes (
Fig. 16
)
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.
CAUTION
When replacing the new carbon brushes, always use genuine Hitachi carbon
brushes with the number speci
fi
ed in the drawing.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head screwdriver. The carbon brushes can then
be easily removed.
