ALIGNING LOWER BLADE
HOLDER WITH UPPER
BLADE HOLDER
The lower blade holder has been aligned with the upper blade holder at the factory and fur- ther alignment should not be necessary; how- ever, to check or adjust the alignment, pro- ceed as follows:
1.MAKE CERTAIN THE MACHINE IS DIS- CONNECTED FROM THE POWER SOURCE.
2.Remove the table insert and place a small straight edge (A) Fig. 32, against the side of the saw blade (B) as shown in Fig. 32.
3.While holding the straight edge (A) Fig. 32, against the saw blade, carefully move the cut- ting arm (E) up and down in a cutting motion. CAUTION: Do not use excessive force on the cutting arm. The saw blade should contact the straight edge during the entire cutting stroke.
4.If an alignment is necessary, rotate adjust- ment screw (C) Fig. 33, to move the lower blade holder (D) left or right, until the saw blade is in consistent contact with the straight edge during the entire cutting stroke.
BRUSH INSPECTION
AND REPLACEMENT
CAUTION: BEFORE INSPECTING THE BRUSH- ES, DISCONNECT THE MACHINE FROM THE POWER SOURCE.
Brush life varies. It depends on the load on the motor. Check the brushes after the first 50 hours of use for a new machine or after a new set of brushes has been installed. After the first check, examine them after about 10 hours of use until such time that replacement is necessary.
The brush holders, one of which is shown at
(A)Fig. 34, are located i-n the motor housing opposite each other. Fig. 35 illustrates one of the brushes removed for inspection. When the carbon (B) on either brush is worn to 3/16" in length or if either spring (C) or shunt wire is burned or damaged in any way, replace both brushes. If the brushes are found serviceable after removing, reinstall them in the same position as removed.
