ORbITAL MOTION
See Figure 8.
The blade of the saw cuts in an orbital motion. This feature
is adjustable and provides faster, more efficient cutting.
With orbital motion the blade cuts through your work in
the upstroke but does not drag across your work in the
downstroke. The higher settings should be used when fast
cutting in soft material is desired. The lower settings should
be used when cutting materials with more resistance. The
“0” setting shuts off the orbital motion. Setting “3” offers the
maximum orbital motion.
STRAIGHT CUT
See Figures 9 - 10.
A straight cut can be made by clamping a piece of wood or
straight-edge to the workpiece and guiding the edge of the
saw against it. Make the cut from one direction only. Don’t
cut halfway and complete the cut from the opposite end.
You can also use an edge guide (not included) as shown
in figure 10. Loosen the thumb screw and insert the end of
the edge guide through the two slots in the base. Measure
the distance to cut and tighten the thumb screw. Place the
edge guide on the outside edge of the workpiece and cut
in a straight path.
WARNING:
To avoid possible serious injury, keep hands and fingers
from between the gear housing and saw blade clamp,
and keep the guard in place.
WARNING:
Excessive side pressure to the blade could result in bro-
ken blades or damage to the material being cut.
ANGLE CUTTING (bEVEL CUTTING)
See Figure 11.
Bevel cutting angles may be adjusted from 0° to 45° right
or left. Angles for cuts from 0° to 45° in 15° increments are
marked on a scale on both the left and right side of the base.
An arrow under the motor assembly provides an indicator at
each of the above mentioned 15° increments. A protractor
is recommended when accurate cuts are required.

Unplug the saw.
 Unlock the base by moving the base adjustment lever
forward.
 Slide the base forward to release it from the 0º detent
position.
 Align the mark of the desired angle with the indicator
arrow located on the housing.
 Once the desired angle is reached, tighten the base
adjustment lever by moving it back under the motor
assembly.
