PLAIN-END BLADE REMOVAL AND
INSTALLATION
This scroll saw accepts 5-inch plain-
end or pin-end blades to cut a wide
variety of materials.
Plain-end type blades are
recommended whenever fine, accurate
and intricate work is being performed
on 3/4 in. or thinner material. It will take
slightly longer to assemble and tension
the blade, but you will also be able to
use finer blades for cutting a thinner
kerf.
To avoid injury from accidental
starting, always turn the switch OFF
and remove power cord plug from
power source before removing or
replacing the blade.
PIN-END BLADE INSTALLATION
(FIG. I, J, K)
NOTE: Do not tighten the set screw (1,
2) when using Pin-end blades. (Fig. J)
In order to avoid uncontrollable
lifting of the workpiece, the teeth
of the blade MUST ALWAYS point
downward. (Fig. I)
