BLADE WIDTH
•
Width of blade describes distance from tip of a tooth
to back of blade.
•
Width of blade affects rigidity of blade. A wider blade
wanders less and produces a straighter cut.
•
Width of blade also limits the smallest radius which can
be cut. A IA" wide blade can cut about a ½" radius.
BLADE THICKNESS
•
Blade thickness describes the distance between
sides of blade. A thicker blade has more rigidity and
stronger teeth.
• A narrow thick blade is used to cut curves while a
wide thin blade is used to make long, straight cuts.
BLADE
PITCH
•
Pitch describes number of teeth per inch or tooth
size. A blade with more teeth per inch produces a
smoother cut.
•
The type of material being cut determines number of
teeth which should be in contact with work.
•
For soft materials, the proper blade has between 6
to 8 teeth per inch.
•
When cutting hard materials, where shocking is
more detrimental, use a blade with 8 to 12 teeth per
inch.
•
There should always be at least three teeth in
contact with cut to avoid shocking blade.
•
Blade shocking occurs when pitch is too large and
blade tooth encounters too much material. This can
strip teeth from blade.
•
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 is done by tilting saw head and using
proper work guide method.
•
Regardless of which work guiding method is used, a
workpiece which overhangs table by more than 5"
needs proper support.
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.
•
Try to stand to front of the saw and use hands over
the portion of table which is to right of blade and
before cut.
•
Cut small corners by sawing around them. Saw to
remove scrap until desired shape is obtained.
BEVEL
CUTTING
Refer to Figure 10.
•
Perform bevel cutting by tilting head to desired
degree.
•
Unlock head by loosening locking handle located on
the backside of the unit (see Figure 12).
•
Tilt head to desired position by rotating crank handle
(see Figure 13).
•
Lock head in position by tightening locking handle
(see Figure 12).

MITER GAUGE
•
Use miter gauge for securing and holding workpiece
at desired angle to produce angled cuts. Use scale
to adjust gauge to desired angle.
WARNING:
Never use miter gauge and rip fence at
the same time. The blade might bind in the workpiece.
Operator could be injured and/or workpiece could be
damaged.
BLADE
CLEANING
BRUSH
Refer to Figure 14.
•
Make sure that brush (Key No. 13) is in contact with
blade to properly remove foreign particles from drive
wheel.
