Installation
General
• Do not install the machine in a damp, humid, dirty or badly illuminated environment.
Machine Setup
The band saw has been pre-adjusted at the factory and several test pieces have
been cut to verify cutting accuracy. Setup of the machine is limited to uncrating the
machine, securing it to the shop floor and connecting it to the electrical power source.
1. Remove the saw from the shipping skid; discard any hold-down devices.
2. Place the saw on the shop floor. This machine must be installed on a firm, level
surface. Make sure it is mounted securely to the floor using mounting anchors
secured through the holes in the base. In addition, adjust the level of the
worktable by adjusting the four feet pads.
3. If the saw will be used to cut long pieces of stock, allow plenty of room for the
length of the stock.
Electrical Connections
A qualified electrician should make the electrical connections
following all local and state codes.
The machine uses high voltage electrical power that poses a
significant risk of serious injury or death if proper precautions
are not observed. Make sure the machine is properly
grounded.
Connect the machine to the electrical power branch circuit. 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).

pulley grooves of the pulley for the desired speed (Refer to Figure 5 for belt
locations and the speeds available).
6. Lower the motor to tighten the V-belt.
Figure 5: Belt Speed/Position Relationship
Blade Selection
The band saw is delivered with a saw blade that is adequate for a variety of jobs on a
variety of common materials. Refer to Figure 5 for the speeds recommended for various
materials. These speeds, while appropriate for many common cutting needs, do not
encompass the wide variety of special blade configurations (tooth pitch and set) and
Blade Removal and Installation
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 work piece at all times for proper cutting. The
blade and work piece can be damaged if the teeth are so far apart that they straddle the
work piece.
For very high production cutting of special materials, or to hard-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 work piece 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.
Use leather gloves when changing the saw blade to protect your hands from
cuts and scratches. Use protective eye wear that meets ANSI SPECIFICATION
Z87.1.
Disconnect the band saw from its electrical power source.
12
1. To remove the blade, place the saw frame in the rearmost position by pushing down
on the saw frame release lever (Figure 3 Item 2) and lock it by turning the saw frame
release knob (Figure 3 Item 1.2) clockwise.
2. Remove the panel on the base to expose the lower blade wheel.
3. Open the panel on the saw head to expose the upper blade wheel.
4. Remove the blade safety guard.
5. Turn the blade tension handle (Figure 3 Item 3) counterclockwise until the blade
hangs loose.
6. Use leather gloves to prevent cuts and scratches. Pull the blade off the drive wheels
and out of the blade guides. Store the removed blade carefully before proceeding.
7. To install the blade, slide the new blade into the blade guides.
8. Place the blade over the bottom wheel.
9. Place the blade over the top wheel. The teeth must point down toward the table.
10. Push the blade so it is seated against the shoulders of the wheels.
11. Turn the blade tension handle clockwise enough to hold the blade firmly in place.
12. Reconnect the saw to its electrical power source.
13. Turn the machine on to allow the blade to position itself. Check and adjust the
tracking of the blade. Refer to Blade Tracking Adjustments in this manual.
14. Turn the blade tension handle clockwise to finish tightening the blade. Do not overtighten the blade; tighten it just enough so it does not slip while cutting.
15. Install the wheel guards and blade covers.
The most common causes of your band saw not cutting straight are:
1. Blade tension is set to low.
2. The blade is either dull or worn on one side.
3. The blade is upside down. The teeth must point down toward the
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 break-in of JET-supplied blades on lower alloy ferrous materials.
1. Clamp a section of round stock in the vise. The stock should be two 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 about 1/3 of the cut, increase the feed rate slightly and
allow the saw to complete the cut.
4. Keep the feed rate at the same setting and begin a second cut on the same or similar
work piece.
5. When the saw has completed about 1/3 of the cut, increase the feed rate while
watching the chip formation until cutting is at its most efficient rate (refer to Evaluating
Cutting Efficiency in this manual). Allow the saw to complete the cut.
6. The blade is now considered ready for use.
Controlling the Cut
Hydraulic Feed Control
The weight of the saw frame provides the force needed to cut through the work piece.
The saw has a hydraulic cylinder that controls the feed rate.
The hydraulic feed control circuit consists of a single-acting hydraulic cylinder and a flowcontrol valve. The feed control cylinder resists motion in the forward direction to control
table.
13
the feed rate. The control cylinder offers no resistance when the saw frame is moved
backward. A knob on the control panel controls the rate at which the saw frame moves
forward. 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, force.
Opening the needle valve further increases the feed rate and applies more force to the
saw blade and the work piece.
The needle valve is adjusted until the saw is operating efficiently. The efficiency of
operation is usually evaluated by observing chip formation. (Refer to Evaluating Cutting
Efficiency for more information on cutting efficiency.
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 to 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 to 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.
Setting the Vise for Angle Cuts
The vise can be adjusted through a 45
o
arc. Adjust as follows:
1. Loosen the hex head bolt and remove the taper pin on the vise.
2. Rotate the vise to the desired angle. For accurate cuts, use a variable protractor
to set the position of the jaw; align one side of the protractor with one side of the
blade.
3. Re-install the taper pin and tighten the hex head bolt on the vise.
Setting the Vise for Square Cuts
The procedure for setting the vise for square cuts is identical to setting for angle cuts (see
Setting the Vise for Angle Cuts) except that a machinist’s square is used to position the
vise.
Work Setup
1. Move the saw frame to its rearmost position by pushing down on the saw frame
release lever (Figure 3 Item 2) and lock it in place by turning the saw frame release
knob (Figure 3 Item 1.2) clockwise.
2. Turn the c-clamp handle counterclockwise enough to fit the stock.
3. Place the work piece on the worktable. For long work pieces, provide support at the
other end. If necessary, provide additional downward clamping to hold the work piece
securely on the worktable.
Setting the Blade Guide Bracket
4. Clamp the work piece in the vise by rotating the c-clamp handle clockwise.
Do not allow the blade to rest against the work piece when the saw is not
cutting.
The band saw has an adjustable blade guide bracket. The blade guide bracket allows
you to set the blade guide for varying heights of work pieces.
To make accurate cuts and prolong blade life, the blade guide bracket should be set one
inch above the piece to be cut. Adjust the bar position as follows:
14
1. Place the work piece in the vise and clamp tightly.
2. Loosen the locking knob on the back of the guide bracket (Figure 3 Item 5).
3. Slide the guide bracket to the desired position.
4. Tighten the locking knob to secure the guide bracket.
Starting the Saw
1. Make sure that the saw frame is in the rearmost position and turn the saw frame
release knob (Figure 3 Item 1.2) to the OFF (clockwise) position.
2. Clamp the work piece in the vise. (Refer to Figure 6 for examples of how different
shaped work pieces are clamped in the vise).
3. Be sure that the blade is not in contact with the work piece when the motor is started.
4. Start the motor and allow the saw to come up to speed.
5. Turn the feed rate knob clockwise all the way. This closes the hydraulic valve and
stops the feed rate.
6. Turn the saw frame release knob counterclockwise to the ON position.
7. Pull up on the saw frame release lever (Figure 3 Item 2) to release the saw frame.
8. Slowly let the saw feed into the work piece by turning the feed rate control knob
(Figure 3 Item 1.3) counterclockwise until the proper feed rate is reached (See
Evaluating Cutting Efficiency).
9. Do not force the cut. Let the weight of the saw provide the cutting force.
10. At the end of the cut, push down on the saw frame release lever to move the saw
frame back to the rearmost position and turn the saw frame release knob clockwise
to lock it.
Never operate the saw without the blade covers in place.
Make sure the blade is not in contact with the work piece when the motor is
started. Do not force the saw through the work piece.
15
Service and Maintenance
Adjustments
The efficient operation of the band saw is dependent upon the condition of the saw blade.
If the performance of the saw begins to deteriorate, the first item that you should check is
the blade.
If a new blade does not restore the machine’s cutting accuracy and quality, refer to the
troubleshooting guide (or the blade manufacturer’s guide) for conditions to consider and
adjustments that can be made to increase the life of the blade.
To change the blade, refer to the blade changing procedures in the Blade Selection
section of this manual.
Blade Tracking Adjustments
Blade tracking has been tested at the
factory. Adjustment is rarely required
when the blade is used properly and if
the blade is correctly welded. (Refer to
Figure 7 for location of blade tracking
adjustment setscrew).
1. Place the saw frame in its
rearmost position by pushing
down on the saw frame release
lever (Figure 3 Item 2) and lock
it in place by turning the saw
frame release knob (Figure 3
Item 1.2) clockwise.
2. Make sure the blade is properly
tensioned.
NOTE: Keep proper tension on
the blade at all times using the
blade tension adjustment.
3. Loosen the two bottom bolts
(Figure 6, Item B) on the wheel
slide.
While performing the following
steps, keep the blade from
rubbing excessively on the
shoulder of the wheel.
Excessive rubbing will
damage the wheel and/or the
blade.
4. Start the saw. Turn the setscrew
to tilt the idler wheel until the
blade is touching the shoulder
of the idler wheel.
5. Turn the setscrew (Figure 6,
Item A) so the blade starts to
move away from the shoulder of
the wheel; then immediately
turn the setscrew in the other
direction so the blade stops;
then moves slowly towards the
shoulder.
Figure 6: Blade Tracking Adjustment
16
Keep your fingers clear of the blade and wheel to avoid injury.
6. Turn the setscrew to stop the motion of the blade on the wheel as it gets closer to
the wheel shoulder. Put a six-inch length of paper between the blade and the
wheel. The paper should not be cut as it passes between the wheel shoulder and
the blade.
7. Turn the setscrew a small amount. Repeat the insertion of the paper between the
wheel shoulder and the blade until the paper is cut in two pieces.
NOTE: You may have to repeat the check with the paper several times before the
blade and the shoulder cut the paper into two pieces. Do not hurry the
adjustment. Patience and accuracy here will pay off with better, more accurate,
quieter cutting and much longer machine and blade life.
8. When the paper is cut, turn the setscrew slightly in the counterclockwise direction.
This assures that the blade is not touching the shoulder of the wheel.
9. Shut off the saw.
10. Tighten the two bottom bolts on the upper wheel slide (Figure 6, Item B).
Blade Guide Bearing Adjustment
Proper adjustment of the blade guide bearings is critical to efficient operation of the band
saw. The blade guide bearings are adjusted at the factory. They should rarely require
adjustment. When adjustment is required, readjust immediately. Failure to maintain
proper blade adjustment may cause serious blade damage or inaccurate cuts.
It is always better to try a new blade when cutting performance is poor. If performance
remains poor after changing the blade, make the necessary adjustments.
If a new blade does not correct the problem, check the blade guides for proper spacing.
For most efficient operation and maximum accuracy, provide 0.001” clearance between
the blade and the guide bearings. The bearings will still turn freely with this clearance. If
the clearance is incorrect, the blade may track off the drive wheel.
Disconnect the band saw from its electrical power source.
Check the blade to make sure the welded section is the same thickness as the
rest of the blade. If the blade is thicker at the weld, the guide bearings may be
damaged.
If required, adjust the guide bearings as follows:
1. The upper and lower blade guides are adjusted the same way.
2. Loosen the blade guide setscrews with an Allen wrench.
3. Position the bearing by turning
the eccentric shafts. Set the
clearance to approximately
0.001”. (See Figure 7).
4. Tighten the blade guide
setscrews with the Allen
wrench.
5. Use the same procedure to
adjust the other blade guide
bearing.
6. When the adjustment is correct,
the guide bearings should
rotate freely with slight pressure
of the finger (blade stopped).
Figure 7: Guide Bearing Adjustment
17
Cleaning
1. Clean off any oil and grease on the machine surfaces.
2. After cleaning, coat the machined surfaces of the band saw with medium
consistency machine oil. Reapply the oil coating at least every six months.
3. Clean up accumulated saw cuttings after use. Make sure the lead screw and the
rapid nut are kept free from saw cuttings and other material that would cause
damage.
Lubrication
Lubricate the following components at the recommended intervals using the lubricants
specified:
1. Ball bearings: the bearings are lubricated and sealed – periodic lubrication is not
required.
2. Blade guide bearing: the bearings are lubricated and sealed – periodic lubrication
is not required.
3. Upper wheel bushing: six to eight drops of oil each week.
4. Pivot points, shafts and bearing areas: six to eight drops of oil each week.
