Operation; General Procedure; Ripping; Crosscutting - Jet JWBS-15 Operating Instructions And Parts Manual

On 3- and 5-horsepower models, the on button will
light up when it is pushed and saw is operating.
(There is no light on 1-3/4 HP models.)
The switch has a safety feature that prevents
unauthorized or accidental starting of the machine.
With band saw turned off, slide safety key (C, Figure
8-1) up and remove it from switch. This piece must
be re-inserted before band saw can operate.

9.0 Operation

The following section contains basic information,
and is not intended to cover all possible applications
or techniques using the band saw. Consult
published sources of information, acquire formal
training, and/or talk to experienced band saw users
to gain proficiency and knowledge of band saw
operations.
(The following figures may or may not show your
specific band saw, but procedures are the same.)

9.1 General procedure

1. Make sure the blade and upper and lower
bearings are properly adjusted for tension and
tracking.
2. Adjust blade guide assembly so that the guide
bearings are just above workpiece (about 3/16")
allowing minimum exposure to blade. See
Figure 9-1.
3. If using the fence, move it into position and lock
it to the guide rail. If you are using the miter
gauge for a crosscut, the fence should be
moved safely out of the way.
4. Turn on band saw and allow a few seconds for
the machine to reach full speed.
Whenever possible, use a push
stick, hold-down, power feeder, jig, or similar
device while feeding stock, to prevent your
hands getting too close to the blade.
5. Place the straightest edge of the workpiece
against the fence, and push the workpiece
slowly into the blade. Do not force the
workpiece into the blade.
When cutting, do not overfeed
the blade; overfeeding will reduce blade life and
may cause the blade to break.
6. When cutting long stock, the operator should
use roller stands, support tables, or an assistant
to help stabilize the workpiece.

9.2 Ripping

Ripping is cutting lengthwise through the workpiece,
and with the grain (of wood stock). See Figure 9-2.

9.3 Crosscutting

Crosscutting is cutting across the grain of the
workpiece, while using the miter gauge to feed the
workpiece into the blade.
Slide the bar of the miter gauge into the end of the
slot on the table.
The right hand should hold the workpiece steady
against the miter gauge, while the left hand pushes
the miter gauge past the blade, as shown in Figure
9-3.
Do not use the fence in conjunction with the miter
gauge. The offcut of the workpiece must not be
constrained during or after the cutting process.
Using the fence in conjunction
with the miter gauge can cause binding and
possible damage to the blade.
