OPERATION (CONTINUED)
BLADE PITCH
•
Pitch describes number of teeth per inch or tooth size. A blade
with more teeth per inch will produce a smoother cut.
•
Use a finer (more teeth/inch) blade for thin workpieces and
hard materials.
•
Use a coarser (less teeth/inch) blade for thick workpieces and
softer materials.
•
There should always be at least two teeth in
contact with workpiece.
•
Blade manufacturers are prepared to supply
information about blades for specific applications.
TYPE OF CUT
•
Contour cutting is done by guiding workpiece
free-handed to produce curved shapes.
•
Beveled cutting can be done by tilting saw arm and using
proper work guide method.
•
Regardless of which work guiding method is used, a workpiece
which overhangs table by more than 5² should be properly
supported
CONTOUR SAWING
•
When contour sawing, use both hands to keep work-piece flat
against table and guided along desired path.
•
Avoid positioning hands in line with blade. If hands slip, they
could contact blade.
•
Cut small corners by sawing around them. Saw to remove scrap
until desired shape is obtained.
BEVEL CUTTING
Refer to Figure 12, page 7.
•
Perform bevel cutting by tilting head to desired degree.
•
Unlock head by loosening locking handle located on the back-
side of the unit.
•
Tilt head to desired position.
•
Lock head in position by tightening locking handle.

CLEANING
•
Keep machine and workshop clean. Do not allow sawdust to
accumulate on scroll saw.
•
Keep mechanisms and threaded or sliding surfaces clean and
free of foreign particles.
LUBRICATION
•
The shielded ball bearings are permanently lubricated and
require no further lubrication.
•
Small amounts of machine oil can be applied to belt tension
mechanisms and threaded or sliding surfaces.
•
Occasionally apply a coat of paste wax to table top to keep it
slick and corrosion free.
