The left and right blade guide brackets (A) and (B) Fig. 22, are adjustable by loosening the two lock knobs (C) and sliding the brackets to accommodate the width of the work piece. The guide brackets (A) and (B) should be set as close as possible to the workpiece, without interfering or touching the workpiece, or contacting the table. Once the adjustment is made, tighten the lock knobs (C).

ADJUSTING FEED RATE

DISCONNECT MACHINE FROM

POWER SOURCE.

The feed rate of the saw arm can be adjusted by turning the control arm (A) Fig. 23, counterclockwise to increase or clockwise to decrease the feed rate. Do not turn the control arm more than one turn at a time. Excessive feed pressure can break or stall the blade. Insufficient feed pressure dulls the blade rapidly.

The vise can be adjusted to cut any angle from 0 degrees to 45 degrees by loosening the two screws (C) Fig. 25, and positioning the vise jaw (D) to the desired angle. A scale (E) is positioned on the rear of the table to give the proper cutting angle. lt may also be necessary when angle cutting to move the left vise jaw (F) to the rear to clear the blade guide bracket.
