OPERATING INSTRUCTIONS
8. Metal Cutting
The saw can be used to cut metals, such as sheet steel, pipe, steel rods, aluminum, brass, and
copper. Be careful not to twist or bend the saw blade. Do not force the tool.
The use of cutting oil is recommended when cutting soft metals and steel. Cutting oil will keep the
blade cool, increase cutting action, and prolong blade life.
WARNING
• Never use gasoline as a cutting lubricant, because normal sparking could ignite the fumes.
a. Securely clamp the workpiece in position and make the cut close to the clamping point to
minimize vibration.
b. When cutting conduit pipe or angle iron, clamp the work in a vise, if possible, and cut close to
the vise.
c. To cut thin sheet material, "sandwich" the material between pieces of hardboard or plywood
and clamp the layers together to reduce vibration and tearing of the material.
9. Plunge Cutting (Fig. 8)
Your 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 performed 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 surfaces.
a. Remove the battery pack from the saw.
b. Make sure that the work piece is firmly clamped in
place.
c. Use the appropriate type and size of blade for the
work piece material and size.
d. Insert the blade into the tool.
e. Adjust the pivoting shoe (B) as necessary to make
sure that the blade will extend beyond the pivoting
shoe and the work piece at all times.
f. Adjust the pivoting shoe as necessary to expose
unworn blade teeth for longer blade life.
g. Check for clearance behind the work piece so that
the blade will not impact another surface.
h. Attach the battery pack to the saw.
i. If the blade is inserted with the teeth facing downward, hold the tool as shown in Column A,
resting the edge of the pivoting shoe on the work piece.
j. With the blade just above the work piece, press the switch-lock button (F) to unlock the trigger
switch and squeeze the variable-speed trigger switch (G) to start the saw and bring it to the
maximum desired cutting speed. Then, using the edge of the shoe as a pivot, lower the blade
into the work piece.
