4. How to use metallic block (Fig. 8)
When the cut-off wheel has a reduced outer diameter,
insert between the vise (A) and (B) a metallic block
slightly smaller than the dimension of workpiece
being cut to use the cut-off wheel economically.

The motor employs carbon brushes which are
64
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one 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 ensure that they slide freely within
the brush holders.
