5. Inspecting the carbon brushes (Fig. 18)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or
near the "wear limit". In addition, always keep carbon
brushes clean and ensure that they slide freely within
the brush holders.
NOTE
When replacing the carbon brush with a new one, be
sure to use the Hitachi Carbon Brush Code No. 999054.
6. Replacing carbon brushes
Take out the carbon brush by first removing the
brush cap and then hooking the protrusion of the
carbon brush with a slotted head screw driver, etc.,
as shown in Fig. 20.
When installing the carbon brush, choose the direction
so that the nail of the carbon brush agrees with the
contact portion outside the brush tube. Then push it
in with a finger as illustrated in Fig. 21. Lastly, install
the brush cap.
CAUTION
Be absolutely sure to insert the nail of the carbon
brush into the contact portion outside the brush tube.
(You can insert whichever one of the two nails
provided.)
Caution must be exercised since any error in this
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
7 Cleaning of the outside

cloth or a cloth moistened with soapy water. Do not

they melt plastics.
8. Storage
