*1 Before beginning work, check to ensure that operating
the switch correctly turns the tool ON and OFF.
While the tool is plugged in to the receptacle, ensure that
the sawblade stops when the switch is turned OFF.
MAINTENANCE AND INSPECTION
1. Inspecting the saw blade
Since use of as 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. 15)
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.
