11.This saw uses 5 in. long pin or plain end type blades.
12.Blades wear faster when cutting plywood or
particle board which is very abrasive. Angle cutting
in hardwoods reduces blade tooth set faster due to
the blade deflection.
FREEHAND CUTTING (FIG. U)
WARNING
To avoid injury from an accidental start, make sure
the switch is in the OFF (O) position and the plug is
not connected to the power source outlet.
1. Lay out desired design, or secure design to the
workpiece (1).
2. Raise the blade guard foot (2) by loosening the blade
guard foot lock knob (3).
3. Position the workpiece against the blade and place
the blade guard foot slightly above the top surface of
the workpiece.
4. Secure the blade guard foot (2) by tightening the
blade guard foot lock knob (3).
5. Remove the workpiece from the blade prior to turning
the scroll saw ON (I). Pull the variable speed control
knob out and set the desired speed by turning the
control knob clockwise or counterclockwise.
CAUTION: In order to avoid uncontrollable lifting of
the workpiece and to reduce blade breakage, do not
turn saw ON (I) while the workpiece is against the
blade.
6. When turning the scroll saw ON (I), position the
workpiece against scrap wood prior to touching the
leading edge of the workpiece against the blade.
7. Slowly feed the workpiece into the blade by guiding
and pressing the workpiece down against the table.
CAUTION: Do not force the leading edge of the
workpiece into the blade. The blade will deflect,
reducing accuracy of cut, and may break.
8. When the cut is complete, move the trailing edge of
the workpiece beyond the blade guard foot. Turn the
scroll saw OFF (O).
