Sawing Tips
Following a few simple tips will reduce the
wear on the workpiece, the tool and the
operator.
1. Blades cut on the draw or back stroke.
On fine work, such as paneling, fiberglass,
etc., place the good side of workpiece
facing down.
2. Use the correct saw blade for the material
being cut and keep extra blades on hand
to use when others become dull. Replace
cracked or bent blades immediately.
3. Select the appropriate cutting speed.
4. To reduce the risk of injury, be sure the
blade always extends beyond the
footplate and work throughout the stroke.
Blades may shatter if the front on the
blade hits the work and/or the footplate.

5. When cutting metal:
- Apply a lubricant for easier, smoother,
faster cutting and longer blade life.
- For non-ferrous metals, aluminum, bronze
or brass, use a stick wax on the blade.
- For ferrous metals, iron and steel, use
machine or cutting oil along the surface to
be cut.
6. When cutting thin metal, "sandwich" the
material between two pieces of scrap
wood. Clamp or put in a bench vise. One
piece of lumber on top of the metal can
be used with adequate clamping. Place
your cut lines or design on the wood.
7. Don't force the cutting. Let the saw and
blade do the work.
Pocket Cuts Pocket/Plunge
Cuts
The reciprocating saw can be used to make
plunge cuts into softer material, (for
example, wood or light building materials
for walls), without a starting hole (Fig. 4).
1. Mark the line to be cut clearly on the
work.
2. Set the tool with one edge of the
footplate firmly against the material.
3. Place the tip of the blade (not running) on
the line to be cut.

4. Tilt the saw so that the blade clears the
work.
5. Squeeze the trigger switch and carefully
engage the moving saw blade into the
material.
6. After the blade penetrates through the
work, continue sawing along the marked
outline.
To make plunge cutting easier, use a heavy
gauge blade, install the blade with the teeth
facing upward, and hold the saw upside
down as shown (Fig. 5).
Do not plunge cut in metal surfaces.
In thick materials and in harder materials,
such as metal, plunge cutting should not be
attempted. Such materials can be cut with
the recip saw only by starting the cut from
the edge of the material or from a hole
drilled all the way through the material that
is large enough to fit the saw blade.
