Operating Controls

START/STOP Switch

The START/STOP switch (refer to Figure 5) is
used to turn on the band saw drive motor. The
START switch has a molded guard which prevent
inadvertent pressing of the START pushbutton.

The STOP pushbutton is not guarded to allow use
as an E-stop in an emergency.

Variable Speed Control

The variable speed control (refer to Figure 9) is
used to change the speed of the saw blade. Refer
to Adjusting Blade Speed for additional informa-
tion on the use of the variable speed control.

Operating Instructions

Saw blades

The Wilton 14-inch saws accept blades from 1/8-
inch wide to 3/4-inch wide. The narrower widths
are used for cutting shapes or circles; the wider
widths are used for straight cuts.

For straight cuts, use the widest available saw
blade. A wide blade provides cutting stability, and
allows for more accurate and straighter cuts.
Blade speed effects the efficiency of the cut and
the service life of the blade. Good shop practice
requires that work-hardening materials, such as
stainless steel, require the cut be completed in a
single pass. Otherwise, the effect of stopping the
cut can result in hardening of the cut interface.

Other materials such as wood require higher blade
speeds to prevent fiber tearing. The chart in

Figure 6 provides suggested blade speeds for
various
types of materials. The recommended speeds
should be decreased 30 to 50% when using
carbon steel blades. (The chart provides speeds
that are based on cutting a 4-inch thick work piece
using a bi-metal blade without cutting fluid.)

The following conditions should also be consid-
ered:
1. Increase speed 15% for materials 1/4-inch

thick, 12% for 3/4-inch thick, 10% for 1 1/4-
inch thick, and 5% for 2 1/2-inch thick.

2. Decrease speed 12% when cutting 8-inch thick

material.

To avoid tooth breakage, select a blade-tooth pitch
that will have two or more teeth in contact with the
workpiece at all times.

Different blade materials and tooth geometry (pitch
and set) permit sawing a wide range of common
and exotic materials. Contact your industrial
distributor for recommendations on specialized
blades. Using the corrrect blade can save you
time, trouble, and the possibility of dulling and
pemature discarding of the blade you normally
might use. NOTE: Always use a sharp blade.
SHARP BLADES ARE CHEAP INSURANCE
AGAINST POOR CUTTING EFFICIENCY AND
ACCELERATED MACHINE WEAR.
