DEPTH ADJUSTMENT
Disconnect plug from power source. Loosen
the depth adjustment lever located between
the guard and handle of saw. Hold the foot
down with one hand and raise or lower saw by
the handle. Tighten lever at the depth setting
desired. Check desired depth (Fig. 3).
Not more than one tooth length of the blade
should extend below the material to be cut, for
minimum splintering (Fig. 4).
-9-
90° CUTTING ANGLE CHECK
Disconnect plug from power source. Set foot
to maximum depth of cut setting. Loosen bevel
adjustment lever, set to 0° on quadrant,
retighten lever and check for 90° angle
between the blade and bottom plane of foot
with a square (Fig. 5). Make adjustments by
turning the small alignment screw, if necessary
(Fig. 6).
BEVEL ADJUSTMENT
Disconnect plug from power source. The foot
can be adjusted up to 50° by loosening the
bevel adjustment lever at the front of the saw.
Align to desired angle on calibrated quadrant.
Then tighten bevel adjustment lever (Fig. 7).
Because of the increased amount of blade
engagement in the work and decreased
stability of the foot, blade binding may occur.
Keep the saw steady and the foot firmly on the
workpiece.
Operating Instructions
LINE GUIDE
For a straight 90° cut, use right side of notch
in the foot. For 45° bevel cuts, use the left side
(Fig. 8). The cutting guide notch will give an
approximate line of cut. Make sample cuts in
scrap lumber to verify actual line of cut. This
will be helpful because of the number of
different blade types and thicknesses
available. To ensure minimum splintering on
the good side of the material to be cut, face
the good side down.
