7. DON’T FORCE TOOL It will do the job better and
safer at the rate for which it was designed.
8. USE RIGHT TOOL Don’t force tool or attachment
to do a job for which it was not designed.
9. USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in
loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the
cord.
10. WEAR PROPER APPAREL Do not wear loose
clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair
covering to contain long hair.
11. WEAR EYE PROTECTION. Always use safety
glasses. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only have impact
resistant lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold
work when practical. It’s safer than using your hand
and it frees both hands to operate tool.
13. DON’T OVERREACH. Keep proper footing and
balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp
and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
15. DISCONNECT TOOLS before servicing; when
changing accessories, such as blades, bits, cutters,
and the like.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in off position before plugging in.
17. USE RECOMMENDED ACCESSORIES. Consult the owner’s manual for recommended accessories. The use of improper accessories may cause risk
of injury to persons.
18. NEVER STAND ON TOOL Serious injury could
occur if the tool is tipped or if the cutting tool is unintentionally contacted.
19. CHECK DAMAGED PARTS. Before further use of
the tool, a guard or other part that is damaged should
5
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.
20. DIRECTION OF FEED. Feed work into a blade or
cutter against the direction of rotation of the blade or
cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool until it comes
to a complete stop.
22. DO NOT REMOVE JAMMED CUTOFF PIECES
until the blade has stopped.
23. MAINTAIN PROPER ADJUSTMENT of blade ten-
sion, blade guides and thrust bearings.
24. ADJUST UPPER BLADE GUIDE TO JUST CLEAR
WORKPIECE.
25. HOLD WORKPIECE FIRMLY AGAINST TABLE.
General Electrical Cautions
This saw should be grounded in accordance with
the National Electrical Code and local codes and ordinances. This work should be done by a qualified
electrician. The saw should be grounded to protect
the user from electrical shock.

Band Saw Features
Refer to Figures 1 through 3 for key features of the
band saw machine. Refer to the Specifications section for additional information on the features and capabilities of the saw.
Set-up
The band saw is shipped with the saw frame
separated from the saw base. Set-up of the band
saw involves installing the frame and setting-up the
saw on the shop floor.
Assembly of Band Saw
The saw is shipped as two separate units — saw
frame and base. The saw frame must, therefore,
be assembled to the base.
1. Remove loose parts from the saw base and
sawframe.
2. Place the base in the location in the shop and
bolt the base to the floor. (See following
section on spotting saw.) Put shims under the
hold-down bolts as required to make sure the
saw is level.
3. Place the saw frame on the base. Be sure the
pulleys on the saw frame and pulleys in the
base are aligned with each other.
4. Install the four bolts, upper washers, lower
washers, lock washers and nuts that secure
the frame to the base finger tight. Using a
straight edge, align the pulleys. Then tighten
the four attachment bolt and nuts.
5. Loosen the motor mounting bolts and install
the drive belt(s).

7. Check gearbox fluid level in sight gauge. If
required, add lubricant to bring level halfway up
the sight gauge. (Two containers of Shell
Spirax 90 HD gear oil are packed with the saw.
The containers have sufficient amount of
lubricant to fill the gearbox.)
8. Check blade tension and support mechanism
adjustment (refer to Changing Saw Blades).
9. Plug the motor cable into the switch box on the
saw frame. For 3-phase motors, follow the
instructions in the Electrical section to complete the electrical hookup.
NOTE: Observe all electrical codes. Local codes or
difficult environmental conditions may demand special electrical hook-ups. Always use a licensed
electrician for any special electrical hook-up.
Setting-up Saw
The saw should be bolted securely to the shop floor
to make sure the saw is stable when sawing long,
heavy or unwieldy work pieces. Always use extra
support for long or heavy stock.
There are lugs in the bottom of the saw base for use
in bolting down of the saw. After positioning the saw,
open the door in the base and mark the positions of
the four lug holes. Move the saw to expose the marks.
Prepare for attachment as required by the attachment
method being used. Install the applicalbe fasteners.
Install shims as required to level the saw. Tighten the
fastners to secure the saw to the floor.
Electrical
Models J-8201 and J-8201VS are delivered with a 115
volt single phase motor. Models J-8203 and J-8203VS
are delivered with a 220/440 volt, 3-phase motor.
Connecting to 3-phase power
1. Disconnect and lock out the branch circuit to
the saw before attempting electrical connections.
2. Connect the green or green-with-white-trace
wire to the branch circuit ground wire.
3. Connect the remaining three wires to the
power wires in the 3-phase branch circuit.
4. Reestablish power in the electrical branch.
5. Turn on power to the saw motor using the
switch.
6. Observe the direction of the blade. It should
be going DOWNWARD, into the slot on the
table. If it is not going downward, the power
wires are hooked-up incorrectly.
7. To correct hook-up, disconnect and lock out
power to the branch, again. Reverse any two
of the power wires on the hook-up to the saw
cable.
8. Reestablish power in the branch and turn the
saw on again. The blade should now be going
downward into the table slot.
Note: local electrical codes or other codes may re-
quire direct connection to a covered, protected junction box, or other electrical hook-up method. Especially under difficult industrial conditions, specialized electrical connections may be necessary.
For special electrical hook-ups, a licensed electrician should be used to connect the saw to power.

GROUNDING INSTRUCTIONS
1. All grounded, cord-connected tools:
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current
to reduce the risk of electric shock. This tool is
equipped with an electric cord having an equipmentgrounding conductor and a grounding plug. The plug
must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the
outlet; have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is
green with or without yellow stripes is the equipmentgrounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is
properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool’s plug.

outlet is not available. The temporary adapter should
be used only until a properly grounded outlet can be
installed by a qualified electrician.(This adapter is
not permitted in Canada) The green-colored rigid
ear, lug, and the like, extending from the adapter must
be connected to a permanent ground such as a properly grounded outlet box.
3. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
between 150 – 250 volts, inclusive:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in Sketch A.
