swing slightly backwards and forwards
as it cuts.
This orbital action increases the
efficiency of cutting. Experiment on a
piece of scrap material to determine
the optimum orbital action setting.
Orbital action increases the efficiency
of cutting, but may result in a rougher
finish to the cut in some materials.
OPERATION
GENERAL CUTTING (Fig.7)
WARNING! Before plugging in the tool, always check to determine that the
switch performs properly and returns to the “OFF” position when released.
WARNING! To help prevent electrical shock, hold the tool only by the plas-
tic handle and the insulated grip area. When sawing into walls or floors you
may encounter electrical wiring. Sawing into a “live” wire will cause electric
shock.
1. Unplug the saw.
2. Make sure that the workpiece is
firmly anchored: clamp the workpiece
to prevent slipping or moving while
cutting.
3. Use the appropriate type and size of
blade for the workpiece material and
size.
4. Adjust the pivot shoe as necessary
to expose unworn blade teeth for longer blade life. Carefully follow the
instructions in Sliding the Shoe In or Out.
5. Check for clearance behind the workpiece so that the blade will not impact
another surface.
6. Clearly mark the line of cut on the workpiece.
7. If cutting metal, apply cutting oil on the line.
8. Plug the reciprocating saw into an electrical outlet.
9. Hold the saw firmly with both hands. Make sure to keep your hands on the
insulated gripping areas only.
10. Depress the trigger switch to start the saw and bring it to the maximum
desired cutting speed before applying the blade to the workpiece.
11. Do not force the tool. Place the shoe firmly on the workpiece while cutting.
Use only enough steady pressure on the blade to keep the saw cutting.
12. Reduce pressure as the blade comes to the end of the cut.
13. Release the trigger switch. Allow the saw to come to a complete stop
before removing the blade from the workpiece.
14. If sawing fiberglass, plaster, wallboard, or spackling compound, clean the
motor vents frequently with a vacuum or compressed air. These materials
are highly abrasive and may accelerate the wear on motor bearings and
brushes.
NOTE: Cutting speeds should vary with the workpiece. Hard materials, such
as metals, require lower speeds; for softer materials use higher speeds.
WARNING! Do not allow familiarity with the saw to make you careless.
One careless fraction of a second is enough to inflict serious injury.
PLUNGE CUTTING (Fig.8)
Your MASTERFORCE reciprocating saw is ideal for plunge cutting directly
into surfaces that cannot be cut from an edge, such as walls or floors. Plunge
cutting may be done two ways depending on how the blade is inserted.
Column A shows how to plunge cut with the teeth of the blade facing down.
Column B shows how to plunge cut with the teeth of the blade facing up.
WARNING! Do not plunge cut into metal material.
1. Unplug the saw.
2. Insert the blade into the tool. If the blade was inserted with the teeth
facing down toward the lower surface of the tool, hold the tool as shown in
Column A, resting the edge of the shoe on the workpiece.
3. If the blade was inserted with the
teeth facing up toward the upper
surface of the tool, hold the tool as
shown in Column B, resting the edge
of the shoe on the workpiece as
shown.
4. With the tip of the blade just above
the workpiece, pull the trigger and
allow the tool to come to the desired
speed.
5. Carefully pivot the tool on the edge of
