3. Inspecting the carbon brushes (Fig. 14)
The motor employs carbon brushes which are
consumable parts. Replace the carbon brush
with a new one when it becomes worn to its
wear limit. Always keep carbon brushes clean
and ensure that they slide freely within the
brush holders.
CAUTION: Using this circular saw with a carbon
brush which is worn in excess of the
wear limit will damage the motor.
NOTE: Use HITACHI carbon brush No. indicated in Fig. 14.
Replacing carbon brushes:
Remove the brush caps (Fig. 1) with a slotted screwdriver. The carbon brushes can then
be easily removed.
CAUTION: When replacing carbon brushes, be sure to use HITACHI No. 38 Carbon
Brushes, as shown in Fig. 14. Use of other carbon brushes will cause the brake
to malfunction.
4. 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. 15) and loosen the
Wing-bolt (A) (Fig. 8).
(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
