Next, tip the saw backward
until the back edge of the shoe
is resting on the work surface
and the blade clears the work
surface (Fig. 11, position 1).
Then, squeeze the trigger
switch and allow saw to come
up to speed. Grip saw firmly
with both hands and begin a
slow, deliberate upward swing
with the handle of the saw,
keeping the bottom of the shoe firmly in contact with the workpiece
(Fig. 11, position 2). Blade will begin to feed into material. Always be
sure blade is completely through material before continuing with
pocket cut.
NOTE: In areas where blade visibility is limited, use the edge of the
saw shoe as a guide. Lines for any given cut should be extended
beyond edge of cut to be made.
METAL CUTTING (FIG. 12)
Your saw has different metal cutting capacities depending upon type
of blade used and the metal to be cut. Use a finer blade for ferrous
metals and a coarse blade for non-ferrous materials. In thin gauge
sheet metals it is best to clamp wood to both sides of sheet. This
will ensure a clean cut without excess vibration or tearing of metal.
Always remember not to force cutting blade as this reduces blade life
and causes costly blade breakage.
NOTE: It is generally recommended that when cutting metals you
should spread a thin film of oil or other lubricant along the line ahead
of the saw cut for easier operation and longer blade life.

HORIZONTAL/VERTICAL SAW MODES (FIG. 13)
The saw can be used in either of the modes shown.
Horizontal Mode: Blade teeth face downward as shown in
Figure 13A.
Vertical Mode: Blade teeth face forward as shown in Figure 13B.
The DCS310 can accept all lengths of reciprocating blades. For best
results use 4" (102 mm) blades. Ensure the blade extends past the
shoe and the thickness of the workpiece during the cut. Use a longer
blade if needed. Whenever possible, the saw shoe must be held firmly
against the material being cut. This will prevent the saw from jumping
or vibrating and minimize blade breakage.
