ADJUSTING DOWNWA R D
TRAVEL OF SAW BLADE
1. DISCONNECT THE S AW FROM THE POWER
SOURCE.
2. The downward travel of the saw blade can be limited
to prevent the saw blade from cont acting any met al
surfaces of the machine. This adjustment is made by
loosening locknut (A) Fig. 38, and turning adjusting
screw (B) in or out until other end of screw (B) cont act s
stop (C) at the full downward travel of the saw blade.
3. When making this adjustment, MAKESURE THE
MACHINE IS DISCONNECTED FROM THE POWER
SOURCE and lower the blade as far as possible. Rot ate
the blade by hand to make cert ain the teeth do not con -
tact any met al surfaces and adjust if necessary. After
adjustment is completed, tighten locknut (A).
ADJUSTING TENSION OF
CUTTINGHEAD RETURN SPRING
The tension of the cuttinghead return spring has been adjusted at the factory in order that the cutting -
head returns to the up position af ter a cut has been made. If it ever becomes necessary to re-adjust the
spring tension, proceed as follows:
1. T urn adjusting screw (A) Fig. 37, clockwise to increase or counterclockwise to decrease the spring
tension.
ADJUSTING SLIDING FIT BETWEEN
CUTTINGHEAD A R M A ND TRUNNION
Af ter a long period of time it may become necessary to adjust the sliding fit between the cuttinghead
arm (B) Fig. 37, and the trunnion (C) by tightening nut (D). Correct adjustment is when a good snug
sliding fit is obt ained between these two p arts. This adjustment should not be too tight that it restrict s
the sliding movement of the cuttinghead arm (B) or too loose that it af fect s the accuracy of the saw cut.
