3.0 SAFETY WARNINGS
1. Read and understand the entire owner’s manual before attempting assembly or operation.
2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these
warnings may cause serious injury.
3. Replace the warning labels if they become obscured or removed.
4. This band saw is designed and intended for use by properly trained and experienced personnel only. If you are not
familiar with the proper and safe operation of a band saw, do not use until proper training and knowledge have been
obtained.
5. Do not use this band saw for other than its intended use. If used for other purposes, JET®, disclaims any real or implied
warranty and holds itself harmless from any injury that may result from that use.
6. Always wear approved safety glasses/face shields while using this band saw. Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.
7. Before operating this band saw, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows.
Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended. Do not
wear gloves.
8. Wear ear protectors (plugs or muffs) during extended periods of operation.
9. CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals known to the State of California to cause cancer, or
birth defects or other reproductive harm.
10. This product, when used for welding, cutting, or working with metal, produces fumes, gases, or dusts which contain chemicals
known to the State of California to cause birth defects and, in some cases, cancer. (California Health and Safety Code Section
25249.5 et seq.)
11. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.
12. Make certain the switch is in the OFF position before connecting the machine to the power supply.
13. Make certain the machine is properly grounded.
14. Make all machine adjustments or maintenance with the machine unplugged from the power source.
15. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed
from the machine before turning it on.
16. Avoid contact with coolant, especially guarding your eyes.
17. Always keeps hands and fingers away from the blade when the machine is running.
18. Never hand hold the material. Always use the vise and clamp it securely.
19. Always provide adequate support for long and heavy material.
20. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme
caution and replace the guards immediately after maintenance is complete.
21. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully
checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts,
binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation.A guard or
other part that is damaged should be properly repaired or replaced.
22. Do not use power tools in damp/wet locations or other dangerous environments. Do not expose them to rain. Keep work
area well lighted. Provide for adequate space surrounding work area and non-glare overhead lighting.
23. Keep the floor around the machine clean and free of scrap material, oil and grease.
24. Keep visitors a safe distance from the work area. Keep children away. Workshop should be childproof; padlocks, master
switches, remove starter keys.
25. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that
can result in serious injury.
26. Maintain a balanced stance at all times so that you do not fall or lean against the blade or other moving parts. Do not
overreach or use excessive force to perform any machine operation.
27. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not
designed. The right tool will do the job better and more safely.
28. Use recommended accessories; improper accessories may be hazardous.
29. Maintain tools with care. Keep blade sharp and clean for the best and safest performance. Follow instructions for
lubricating and changing accessories.
30. Maintain proper adjustment of blade tension, blade guides and thrust bearings.
31. Turn off the machine and disconnect from power before cleaning. Use a brush to remove chips or debris — do not use
your hands.
32. Do not stand on the machine. Serious injury could occur if the machine tips over.

33. Never leave the machine running unattended. Turn the power off and do not leave the machine until it comes to a
complete stop.
34. Be sure that the blade is not in contact with the workpiece when the motor is started. The motor shall be started and you
should allow the saw to come up to full speed before bringing the saw blade into contact with the workpiece.
35. Adjust upper guide to clear workpiece. Hold workpiece firmly against table.
36. Direction of feed — feed work into a blade or cutter against the direction of rotation of the blade or cutter only.
37. Installation work and electrical wiring must be done by qualified electrician in accordance with all applicable codes and
standards.
38. Do not remove jammed pieces until blade has stopped.

6.0 UNCRATING AND ASSEMBLY
Note: Read and understand the entire manual before
attempting setup or operation.
1. Finish uncrating the saw and inspect for damage.
Should any have occurred, contact your local distribu-
tor.
2. Remove any preservatives with kerosene or diesel oil.
Do not use gasoline, paint thinner, or any cellulose-
based product, as these will damage painted
surfaces.
3. Remove two socket head cap screws from left side of
vertical column. Attach shear assembly (A, Figure 1) to
column by inserting screws.
4. Place rip fence onto table and tighten with locking
knob.
7.0 INSTALLATION
For best performance, the band saw should be located on
a solid and level foundation. Allow room for servicing and
for moving large stock around the band saw when decid-
ing a location for the machine.
1. Remove four (4) nuts and washers holding band saw
to shipping crate bottom.
2. Use the lifting ring to lift band saw into its permanent
location. For best performance, band saw should be
bolted to floor after a level position has been found.
3. Using a square, adjust table 90 degrees to blade, both
front to back and side to side. Loosen the hex cap
screws below the table to move it and tighten to
hold table in place. If necessary, adjust the pointers to
zero should they read different once table is perpen-
dicular to blade in both directions.
4. To level the machine, place a machinist’s level on the
table and observe in both directions.
5. Use metal shims under the appropriate hold down
screw. Tighten screw and recheck for level.
6. Adjust with additional shims, as required, until table is
level when all mounting screws (or nuts) are tight.
8.0 ELECTRICAL CONNECTIONS
The Vertical Band Saw is rated at 230/460V and comes
from the factory prewired 230V.
You may either connect a proper UL-listed plug suitable
for 230 volt operation, or “hard-wire” the machine directly
to your electrical panel provided there is a disconnect near
the machine for the user.
The band saw must be grounded. A qualified electrician
can make the proper electrical connections and confirm
the power on site is compatible with the saw.
Before connecting to power source, make sure switch is in
off position.
8.1 VOLTAGE CONVERSION
To switch to 460V operation:
1. Switch the incoming leads in the motor junction box
(follow wiring diagram on inside cover of motor
junction box).
2. Switch the jumper wires on the circuit board. Remove
control panel from saw body and change the jumper
wires according to the list in section 18.0, Electrical
Connections.
3. If a plug is to be used, install a proper UL-listed plug
suitable for 460V operation.
IMPORTANT: Consult the diagrams in section 19.0 for
any clarification of these changes on 230V to 460V con-
version.
8.2 THREE-PHASE TEST RUN
After wiring the band saw, you should check that the wires
have been connected properly. Connect machine to power
source and turn it on for an instant to watch direction of
blade movement.
If blade runs upward instead of downward, disconnect

All electrical connections must be done by a
qualified electrician. All adjustments or repairs must
be done with machine disconnected from power
source. Failure to comply may cause serious injury.
