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.
