Figures 1 and 2 depict the main features of the Model EHB8 Horizontal Cut-Off Bandsaw. The machine consists of a
machine base onto which is installed a saw head.
6.1 MACHINE BASE
The machine base consists of a coolant collection pan
mounted on two panels that form the legs of the machine.
A shelf is provided under the collection pan that supports a
coolant tank.
The machine bed mounts on the top of the collection pan.
The bed supports the vise and the vise-tightening lead
screw.
The coolant tank is equipped with a pump/motor assembly.
The pump/motor circulates coolant through tubing to cool
and lubricate the saw blade, the blade guides, and the
workpiece.
A drainpipe is provided to connect the collection pan to
the coolant tank. A screen is provided in the collection
pan to screen-out cutting debris as the coolant drains into
the coolant tank. Coolant is added to the tank by pouring
coolant into the collection pan. The tank is easily removed
from its shelf for cleaning and maintenance.

6.2 SAW HEAD
The saw head (Figure 2) consists of a drive motor, drive
pulleys, gearbox, blade wheels, blade guides and supports,
control panel, blade tension/blade tracking mechanism,
wire brush, and the saw blade.
The drive motor is mounted on a pivoting plate that swings
outward to provide drive belt tension. The motor is fitted
with a step pulley; the drive belt connects to a second step
pulley that is mounted on the input shaft of the gearbox.
A speed-reducing gearbox is mounted on the back side of
the blade wheel box on the right side of the machine. The
blade wheel (drive wheel) is installed on the output shaft of
the gearbox.
A second blade wheel is located in a blade wheel box on
the left of the machine. The blade wheel (driven wheel) is
mounted on a shaft that is part of the blade tension/tracking
mechanism. The blade tension mechanism is used to
tighten the saw blade on the blade wheels.
The mechanism also has adjustment screws that enable
the saw blade to “track” evenly on the blade wheels. The
adjustment screws change the angle of the driven blade
wheel shaft so the wheels are aligned. Tracking adjustments
are generally made after the saw blade is changed but may
be required periodically due to wear over time.

6.3 WORK STOP
A work stop (refer to Figure 3) is provided with the machine
to allow cutting multiple pieces of identical length (refer to
Figure 12). The stop consists of a rod onto which is installed
a stop bracket, a tapered stop, a clamping knob and a
locking handle. The rod is installed in a bore in the front
of the saw bed. The stop bracket is positioned on the rod
with the tapered stop toward the end of the workpiece. The
bracket is moved in or out on the rod to establish the length
of the workpiece.
7.0 UNPACKING AND ASSEMBLY
7.1 MACHINE SETUP
The cut-off saw has been pre-adjusted at the factory and
several test pieces have been cut to verify cutting accuracy .
Remove the saw from the shipping skid; discard any holddown devices. Place the saw on the shop floor; secure the
saw to the floor using mounting anchors secured through
four holes in the machine base. (Refer to Figure 1 for floor
anchor bracket location). If the saw will be used to cut long
pieces of stock, allow plenty of room for the length of the
stock.
8.0 ELECTRICAL CONNECTION
!
Electrical connection must be made by a licensed
electrician. The wiring methods and practices must
comply with local electrical codes.
Fig. 3
6.4 CONTROL PANEL
The control panel is mounted on a movable arm to the left
of the saw. Refer to the Controls and Indicators section
(section 9.0) for a description of the controls.
6.5 AUXILIARY COOLANT HOSE
Your saw is equipped with an auxiliary coolant hose. This
can be used when a large amount of coolant needs to be
directed at the work piece.
!
The machine uses high voltage electrical power
that poses a significant risk of serious injury or
death if proper precautions are not observed.
Connect the machine to the electrical power branch circuit
(refer to the Wiring Diagram section 19.0). Observe the
following guidelines when connecting the saw to the power
source:
1. Make sure the saw is disconnected from the electrical
power branch circuit (trip the required circuit breakers
or remove the required fuses).
2. Place a warning placard or tag on the service panel
to prevent accidental electrical shock.
3. When installing the motor power cord into a
receptacle, make sure the plug is compatible with the
receptacle.
4. When using hard-wired connections, connect the wires as shown in the Wiring Diagram section.
5. Install the fuses or reset the breakers.
Check operation of the saw.

9.0 CONTROLS AND INDICATORS
9.1 CONTROL PANEL
The operating controls for the cut-off saw are located on the
control panel (Figure 4) and consist of the following controls
and indicators:
Coolant Pump Switch (A) – turns coolant pump on and off.
Emergency Stop Switch (B) – press to stop the drive
motor.
Note: A micro switch also stops the motor when the
workpiece is cut and the saw head is completely down.
Start Switch (C) – press to start the drive motor. The saw
head must be in the raised position.
Power Light(D) – indicates that machine is plugged in and
the outlet circuit breaker is turned on. The machine does not
need to be running for the power light to be on.
!
If the bulb is out, lamp will not light, but machine
may still have power.
9.2 BLADE SPEEDS
The Model EHB-8 horizontal cut-off bandsaw is equipped
with electronic variable speed raging from 80-310 FPM. The
speed change is completed by turning the speed control
knob (Figure 5) located to the right of the machine on the
main motor. Change blade speeds as follows:
1. Raise the saw head so that it is not in contact with a
work piece.
2. Press the motor start button on the main control panel.
3. Adjust the speed to correspond with the material that
you are cutting (Figure 6 on page 9) Note: speeds
are approximate.
!
Adjust speed dial only when machine is running.
Feed Rate Control (E) – this knob is used to set the
amount of downward force that is applied to the saw blade.
The feed rate is proportional to the opening of the valve.
When set to zero, the saw head is locked in the raised
position. Increasing the valve opening (counterclockwise
adjustment) increases the feed rate; decreasing the valve
opening (clockwise adjustment) reduces the feed rate.

10.0 BLADE SELECTION
The cut-off saw is delivered with a saw blade that is
adequate for a variety of cut-off jobs on a variety of common
materials.
Refer to Figure 6 for the speeds recommended for various
materials. These speeds, while appropriate for many
common shop cutting needs, do not encompass the wide
variety of special blade configurations (tooth pitch and set)
and special alloys for cutting unusual or exotic materials.
A coarse blade could be used for a solid steel bar, but a
finer tooth blade would be used on a thin-wall steel tube.
In general, the blade choice is determined by the thickness
of the material; the thinner the materials; the finer the tooth
pitch.
A minimum of three teeth should be on the workpiece at all
times for proper cutting. The blade and workpiece can be
damaged if the teeth are so far apart that they straddle the
workpiece.
For very high production on cutting of special materials, or
difficult to cut materials such as stainless steel, tool steel,
or titanium, you can ask your industrial distributor for more
specific blade recommendations. The supplier that provides
the workpiece material should be able to provide you with
very specific instructions regarding the best blade (and
coolant or cutting fluid, if needed) for the material or shape
supplied.
10.1 BLADE BREAK-IN PROCEDURES
New blades are very sharp and, therefore, have a tooth
geometry that is easily damaged if a careful break-in
procedure is not followed. Consult the blade manufacturer’s
literature for break-in of specific blades on specific materials.
However, the following procedure will be adequate for breakin of Jet-supplied blades on lower alloy ferrous materials:
1. Clamp a section of round stock in the vise. The stock
should be 2 inches or larger in diameter.
2. Operate the saw at low speed. Start the cut with a
very light feed rate.
3. When the saw has completed 1/3 of the cut, increase
the feed rate slightly and allow the saw to complete
the cut.
4. Keep the hydraulic cylinder needle valve in the same
position and begin a second cut on the same or
similar workpiece.
5. When the blade has completed about 1/3 of the cut,
increase the feed rate.
Watch the chip formation until cutting is at its most
efficient rate and allow the saw to complete the cut
(refer to Evaluating Cutting Efficiency section 11.2). The blade is now considered ready for use.
11.0 OPERATIONS
11.1 HYDRAULIC FEED CONTROL
The weight of the saw head provides the force needed to
cut through the workpiece. The cut-off saw has a hydraulic
cylinder that controls the feed rate of the saw.
The hydraulic feed control circuit consists of a single acting
hydraulic cylinder (Figure 7) and a feed rate control (Figure
4). The feed control cylinder resists motion in the downward
direction to control the feed rate. The control cylinder offers
no resistance when raised upward.
The feed rate control knob (Figure 4) controls the rate at
which the saw head is lowered. The control knob (needle
valve) controls the rate at which the hydraulic fluid is
released from the hydraulic cylinder. When the needle
valve is closed, the cylinder is locked. With the needle valve
slightly open, the cylinder permits slow, or light, downward
force. Opening the needle valve further increases the feed
rate and applies more force to the saw blade and workpiece.
The needle valve is adjusted until the saw is operating efficiently. The efficiency of operation is usually evaluated
by observing chip formation. Blade efficiency is further described on the following page.

8-in x 13-in Horizontal Cut-Off Bandsaw
11.2 EVALUATING CUTTING EFFICIENCY
Is the blade cutting efficiently? The best way to determine
this is to observe the chips formed by the cutting blade.
If the chip formation is powdery, then the feed is much too
light, or the blade is dull.
If the chips formed are curled, but colored – blue or straw
colored from heat generated during the cut – then the feed
rate is too high.
If the chips are slightly curled and are not colored by heat
– the blade is sufficiently sharp and is cutting at its most
efficient rate.
11.3 WORK SETUP
Referring to Figure 8:
1. Set the feed rate control knob (C) to zero.
2. With the lifting handle (A) raise the saw head (B).
3. Turn the vise handwheel (D) counter clock-wise enough to free the moveable vise jaw (E). Then pull the moveable vise jaw away from the fixed vise
jaw(H).
4. Place the workpiece (F) on the work table (G). For
long workpieces, provide support at the other end. If
necessary, provide additional downward clamping to
hold the workpiece securely on the worktable.
5. Clamp the workpiece (F) in the vise by first pushing
the moveable vise jaw (E) against the workpiece. Then rotate the vise handwheel (D) clockwise to secure the workpiece.
11.4 SETTING THE VISE FOR ANGLE CUTS
(NON-MITERING VERSION ONLY)
Referring to Figure 9, the vise can be adjusted through a
45-degree arc as follows:
1. Loosen the lock handle (E) that secures the fixed vise
jaw (D).
2. Rotate the fixed vise jaw (D) to the desired angle,
setting it to the scale on the back edge of the table.
For accurate cuts, use a variable protractor to set the
position of the jaw, aligning one side of the protractor
with the blade.
3. Tighten the lock handle (E).
4. Loosen the hex head bolt (A) on the moveable vise
jaw (C).
5. Place the workpiece (B) between the vise jaws (C, D).
6. Set the moveable vise jaw (C), pressing it against the
side of the workpiece (B) and fixed vise jaw (D).
7. Tighten the hex head bolt (A) on the moveable vise
jaw to secure the jaw.
