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.
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. 29) and loosen
the wing bolt (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.
7. Check for dust
Dust may be removed with a clean rag or
a cloth dampened with soapy water.
Do not use bleach, chlorine, gasoline or
thinner, for they may damage the plas-
tics.
8. Disposal of the exhausted battery

The battery must explode if it is
