Introduction
This manual includes the operating and maintenance
instructions for the JET 10-inch by 16-inch Cut Off Band
Saw, Models J-7020/J-7040. This manual also includes
parts listings and illustrations of replaceable parts.
Operating Instructions

Controls

The operating controls for the saw are provided in a
control panel on the left side of the machine. The con-
trol panel is mounted on a pivoting tube. The pivoting
tube allows the operator to position the control panel in
a convenient location.
Figure 1: Control panel
1. A power-on light is provided on the left side of the
control panel. The power-on light indicates when
power is connected to the machine.
2. A n emergency stop button is provided on the
control panel. The emergency stop button pro-
vides a means to rapidly cut off electrical
power.
3. The saw motor pushbutton switch starts the saw
motor and the E-stop button stops the saw motor.
4. A green pushbutton switch is provided to the right
of the emergency stop pushbutton. The pushbutton
opens an electro-magnetic valve in the hydraulic
cylinder circuit. Opening the valves allows the saw
head to move downward and put the saw blade in
contact with the workpiece.
5. A red release button on the electro-magnetic
valve provides a means to lower the saw head
when power to the machine has been discon-
nected (see figure 4).
6. The rate at which the saw head moves downward
is controlled by a hydraulic feed rate control
located on the top, rear of the saw head (see
figure 3).
7. A coolant pump switch is provided on the electri-
cal equipment box on the back of the machine
(see figure 2).

Setting Blade Speed

1. The blade speed is controlled by an adjustment
mechanism on the right end of the saw. Speed
increases when the adjustment knob is turned
counterclockwise. Speed decreases when the
knob is turned clockwise.
2. A placard on the drive belt guard provides recom
mended speeds for various materials.
3. A speed indicator is provided on the barrel of the
adjustment mechanism. The indicator provides
speed indications in feet per minute and meters
per minute. (The meters per minute values are
shown in parenthesis on the indicator.)
4. The feed rates on the placard are expressed in
meters per minute. The feed rate graduations
available on the indicator may not match the
recommended feed rate. An approximate speed
may therefore be required. For example, to set a
speed rate of 25 meters per minute, the indicator
would be set about midway between 21 meters-
per-minute and the 30 meters-per-minute gradu-
ations.
WARNING: TO CHANGE SPEED, THE SAW
MOTOR MUST BE OPERATING.
5. Turn the speed adjustment knob to the desired
rate setting as determined by the material being
cut.
