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. The saw cuts freely with only
slight feed pressure. Forcing the saw will not make it cut faster.
SAWING WOOD
The TIGER 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 TIGER SAW® can be used for plunge cutting wood, plywood,
wallboard, and plastic materials. 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. To start cut, rest saw on pivoting guide
shoe bracket, align blade with the marked line of cut, (blade NOT touching
work), as shown in Fig. 10. Start saw. Using guide shoe bracket as a pivot
point, roll saw forward by raising rear handle, as shown in Fig. 11. When
blade has cut through the work, continue raising the rear handle until saw
is perpendicular to the work surface. Keep saw in this position and move
blade along line of cut.
SAWING METAL
When cutting angle, H-beam, I-beam, channel, etc., start the cut on the
surface where the greatest number of teeth will contact the work. To make
a pocket cut, drill a starting hole first. To extend blade life, cutting oil can be
applied to the work surface along the line of the cut.
