5. Inspecting the carbon brushes (Fig. 14)
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 flat head screw driver,
etc., as shown in Fig. 16.
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. 17. 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. Check for Dust
Dust may be removed with a soft cloth or a cloth dampened with soapy
water.
Do not use bleach, chlorine, gasoline or thinner, for they may damage
the plastics.
