Important - Hitachi C 7BMR Mode D'emploi

3. Inspecting the carbon brushes (Fig. 8)
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 figure 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
specified in the drawing.
For model C7BMR, the brake may not work if other
than the specified carbon brushes are used.
When the brake becomes ineffective, replace the
carbon brushes with new ones.
4. Replacing carbon brushes (Fig. 9)
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. 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.
6. Adjusting the base and saw blade to maintain
perpendicularity
The angle between the base and the saw blade has
been adjusted to 90°, however should this
perpendicularity be lost for some reason, adjust in
the following manner:
(1) Turn the base face up (Fig. 10) and loosen the lever
(A).
(2) Apply a square to the base and the saw blade and
turning the slotted set screw with a slotted-head
screwdriver, shift the position of the base to produce
the desired right angle.
