TO START AND STOP SAW
1. Make sure power circuit voltage is the same as shown on the
specification plate on the saw. Connect saw to power circuit.
2. Hold saw firmly. Squeeze trigger switch (A) Fig. 9, to start motor.
Release trigger to stop motor.
VARIABLE SPEED
The saw is equipped with a variable speed control (0 to 2600 SPM). As the
switch trigger is squeezed, the speed of the saw blade increases.
The lower speeds are recommended for most metal cutting, while the higher
speeds are recommended for wood. A few practice cuts at various speeds
(on scrap material), will aid you in choosing the best speed for obtaining the
desired results on your application.
DUAL BLADE MOTION
The Model 748 has dual blade motion: you have a choice of straight
reciprocating motion, as shown in Fig. 10, or orbital motion as shown in
Fig. 11. Straight reciprocating motion should be used for all metal cutting
operations, and for wood cutting applications where finish is more important
than speed. Orbital motion is used for fast cutting of wood.
