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. 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. 13)
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.
○
For models C6BU2 and C7BU2, the brake may not work
if other than the speci fi ed carbon brushes are used.
When the brake becomes ine ff ective, replace the carbon
brushes with new ones.
5. Replacing carbon brushes
Disassemble the brush caps with a slotted - head
screwdriver. The carbon brushes can then be easily
removed.
6. Replacing supply cord
If the replacement of the supply cord is necessary, this
has to be done by the manufacturer of this agent in order
to avoid a safety hazard.
7. Maintenance of the lower guard
For safe and proper working, always keep the machine
and ventilation slots clean. The lower guard must
always be able to move freely and retract automatically.
Therefore, always keep the area around the lower guard
clean. Remove dust and chips by blowing out with
compressed air or with a brush.
CAUTION
In the operation and maintenance of power tools, the safety
regulations and standards prescribed in each country must
be observed.
