PIVOTING GUIDE SHOE
The Quik-Change
pivoting
guide shoe (A) Fig. 12, serves
as a rest while making a cut.
It is pivoted so the saw may
be gradually raised to a
position perpendicular to the
work as the saw is moved
toward the operator.
WARNING: Do not
operate the tool with the
guide shoe removed.
USING THE SAW
BEFORE YOU START TO WORK
Select the blade best suited for the material to be cut. For greatest economy,
use the shortest blade suitable for the thickness of the material to be cut.
Be sure the material to be cut is rigid. Small work pieces should be securely
clamped in a bench vise or with clamps to the work table. As the work
progresses in scroll or curved cut-out pieces, the material may be readjusted
to accommodate the movement of the saw. If the work is large enough, it
may be held only by hand across saw horses. The saw cuts freely with only
slight feed pressure. Forcing the saw will not make it cut faster.
SAWING WOOD
The variable angle reciprocating saw is used much the same as a hand saw
in that it is moved toward the operator during the cutting operation. However,
since the blade cuts on the up-stroke instead of the down-stroke as in the
case of the hand saw, the good or finish side of the work should face down
during the cutting operation.
PLUNGE CUTS
The variable angle reciprocating saw can be used for plunge cutting wood,
plywood, wallboard, and plastic materials.
WARNING: DO NOT attempt to plunge cut metal.
Clearly mark line of cut on the work. Grasp front housing with one hand and
rear handle with the other hand. Choose a convenient starting point inside
the line of cut in waste material area. To start cut, rest saw on shoe bracket,
align blade with the starting point, (blade NOT touching work), as shown in
Fig. 13. Start saw. Using bracket as a pivot point, roll saw forward by raising
rear handle, as shown in Fig. 14. When blade has cut through the work,
continue raising the rear handle until saw is perpendicular to the work and
guide shoe is fully seated on the work surface. Keep saw in this position and
move blade along line of cut.
