8.0 ELECTRICAL CONNECTIONS
!
All electrical connections must be done by a
qualifi ed electrician. All adjustments or repairs must
be done with machine disconnected from power
source. Failure to comply may cause serious injury.
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 qualifi ed electrician
can make the proper electrical connections and confi rm
the power on site is compatible with the saw.
Before connecting to power source, make sure switch is in
off position.
Fig. 1
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 deciding 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 fl oor 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.
8
8.1 VOLTAGE CONVERSION
To switch to 460V operation:
1. 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.
2. 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 clarifi cation 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
machine from power, and switch any two of the three
leads in the motor junction box (see section 19.0, Wiring
Diagram).

10.6 WORK LAMP BULB
The work lamp uses a standard medium-base 60 watt
bulb (not provided).
11.0 BLADE SELECTION
Proper blade selection is just as important to band saw
operation as is blade speed and material feed. Proper
blade selection will impact blade life, straightness of cut,
cut fi nish, and effi ciency of operation. Excessive blade
breakage, stripping of teeth, and waviness of cut are some
of the results of improper blade selection.
Blades are classifi ed by material composition, tooth
shape, tooth pitch, tooth set, gage of the band material,
and kerf of the set (width of cut).
11.1 MATERIAL COMPOSITION
Carbon Steel – low cost, for use with non-ferrous materi-
als, wood, and plastics.
High Speed Steel – resists heat generated by dry cutting.
Used for ferrous metals.
Alloy Steel – tough and wear resistant, cuts faster with
longer blade life. Used on hard materials. More expensive
than carbon or high speed steel.
Carbide Tipped – for cutting unusual materials such as
uranium, titanium, or beryllium.
12
Vertical Band Saw
11.2 TOOTH SHAPE
Note: When cutting thin materials, the rule for blade
pitch is to have a minimum of two teeth engaging the
material being cut at all times.
Standard Tooth - generally used to cut ferrous metals,
hard bronze, hard brass, and thin metals.
Skip Tooth - have better chip clearance (larger gullet) and
are used on softer, non-ferrous materials such as aluminum, copper, magnesium, and soft brass.
Hook Tooth - provides a chip breaker and has less
tendency to gum up in softer materials. Used in the same
materials as skip tooth but can be fed faster than standard
or skip tooth blades.
11.3 SET TYPE
Straight Set – used for free cutting non-ferrous materials;
i.e., aluminum, magnesium, plastics, and wood.
Wavy Set – used on materials of varying thickness (pipe,
tubing, and structural shapes).
Raker Set – used in large cuts on thick plate and bar stock
where fi nish of cut is not as important as speed.
!
Never adjust guide fi ngers while blade is running.
Failure to comply may cause serious injury.
11.7 BLADE BREAKAGE
Band saw blades are subject to high stresses and breakage may sometimes be unavoidable. However, many factors can be controlled to help prevent most blade breakage. Here are some common causes for breakage:
1. Misalignment of blade guides.
2. Feeding workpiece too quickly.
3. Using a wide blade to cut a short radius curve.
4. Excessive tension.
5. Teeth are dull or improperly set.
6. Upper guides are set too high off the workpiece.
7. Faulty weld on blade.
12.0 WELDER OPERATION
11.4 GAGE
Gage is the thickness of material from which the blade is
produced. The thicker the material, the stronger the blade.
11.5 KERF
Kerf is the width of a cut. Kerf will vary according to the set
of the blade teeth.
11.6 WIDTH
The thinner the blade, the tighter will be the minimum radius
of cut. Always use widest blade possible for the job.
General rules for blade selection:
• Select coarser pitch blades for thicker or softer material.
• Select fi ner pitch blades for thinner or harder material.
• Use fi ne pitch blades to obtain a smooth fi nish.
• Use coarse pitch blades to obtain faster cutting
speeds (thick material).
• To prevent premature blade wear, use fastest practical
speed.
• Adjust feed rate to ensure continuous cutting action.
• Run the bandsaw with blade centered in upper and
lower guides, and guide fi ngers adjusted as close as
possible without touching the blade or weld joint.
!
Wear eye protection while operating welder. Use
care when handling blade after welding to avoid
burns.
The welding procedure involves the following steps:
Shearing the blade, grinding teeth to allow for the weld
area, the actual welding, inspection of blade, annealing,
grinding and a fi nal inspection of blade. This procedure
can be accomplished using the shear and welder assemblies on your band saw. Proceed as follows:
12.1 SHEARING
Cut blade to longest length needed for band saw. Using
the shear to cut your blade will ensure that cut ends are
fl at, square and smooth.
1. Place handle in upright position.
2. Position blade against back of square cutting guide
of shear. See Figure 11. Make sure blade is held
square with shear knife, so that cut will be square
with blade. (Continue on next page).
EVBS-26

3. Position blade so that cut is made at a place that
allows for uniform spacing of teeth. See Figure 12.
4. Bring handle down fi rmly to cut blade.
IMPORTANT: If a blade has been cut by using snips,
the ends of the blade must be ground square before
welding them together, as shown in Figure 14.

If snips are used
to cut blade,
grind ends square
as shown.

12.2 REMOVING TEETH
In fi ne pitched blades, one or more of the teeth on each
side of the cut may need to be removed by grinding so
that the weld area of the blade is uniform and the teeth will
be uniformly spaced. See Figure 12, and refer to section
12.5 Blade grinding.
Clean blade ends which
will contact welder jaws
Cut off blade ends square.
Allow for correct tooth spacing.

The welder is designed for intermittent use. Repeated welding within a short period of time may cause
welder to overheat.
1. Clean welder jaws and lower jaw inserts.
2. Carefully clean ends of blade which will contact
welder jaws. Remove any dirt, oil, scale and oxide.
!
Any rust (oxide) on blade in vicinity of weld must
be ground off before blade can be welded.
3. Turn pressure knob (Figure 14) to “0” position
(pointed downward).
NOTE: There will be some resistance when turning
knob.
4. Insert one end of blade into left clamp. Position back
edge of blade against back edge of left clamp. Then
position the end of the blade midway between left
and right clamps. Tighten left clamp.
5. Insert opposite end of blade into right clamp. Position
back edge of blade against back edge of right clamp.
Then butt the end of blade against the other end of
blade (the blade ends need to be in contact with
each other). Tighten right clamp.

6. Set pressure selector switch (counterclockwise rota tion) to the approximate setting required for the width
of the blade being welded.
!
Misaligned Weld
Keep hands clear of weld area and clamp jaws
during welding.
7. Press and hold weld button (Figure 14). When weld
button is pushed, the left clamp moves to the right to
apply pressure to the blade ends. Simultaneously,
sparks will be emitted from the blade ends as they
are being welded. Do not release weld button until
blade joint is “red hot.”

12.4 ANNEALING
The blade must now be annealed, or cooled at a
controlled rate to prevent it becoming too brittle.
The general procedure follows. Specifi c procedure will
depend upon blade type, as described in sections 12.4.1
through 12.4.3.
1. Turn pressure selector knob all the way to left so
clamp jaws are closest to each other.
2. Insert blade into clamps so that weld area is cen-
tered between clamps. Secure blade in jaws with the
clamp handles.
3. Quickly press and release (“jog”) the anneal button
(Figure 14). Repeat jog process until you see a
slightly red glow from weld area.
8. Release weld button, and wait 3 or 4 seconds until
blade returns to original color. Unclamp blade.
9. Rotate pressure selector switch back to “0”.
10. Remove blade from clamps, and carefully inspect it.
The spacing of the teeth should be uniform and the
weld should be located in center of gullet. Misalign-
ment is easily noted at this time from the weld ap-
pearance. See Figure 15 for examples of incorrect
welds.
11. If the weld is imperfect, refer to section 15.3 for pos sible remedies to any problems. Make corrections
before annealing.
EVBS-26
!
Do not press and hold the anneal push button. The
weld will be overheated and will fail due to excessive heat.
4. Release both blade clamps, allow blade to cool, then
remove blade from clamps.
5. Check weld integrity. Bend blade to form a radius at
point of weld. The size of the radius should be ap-
proximately the same as radius of band saw drive
wheel. The weld must hold and not break or crack af ter forming the radius. If the weld breaks, cut away
welded area and repeat welding-annealing process.
6. Check to make sure welded section is same thick
ness as rest of blade. If not, grind off excess weld
material using the grinder. Refer to section 12.5,
Blade Grinding.
15
!
If blade is thicker at the weld than at the rest of the
blade, using the blade may damage the guides.
The following are variations of the general procedure,
based upon blade type:
12.4.1 CARBON STEEL BLADES
1. Press and jog the annealing switch button until weld
is a “dull cherry” to “cherry red” color.
2. Allow blade to cool slowly by decreasing jogging
frequency.
12.4.2 CARBON STEEL HARD BACK BLADES
1. Heat blade slowly until weld becomes a deep blue
color.
2. Continue to heat by jogging the anneal button until
the width of the blue color is one-half the length of
the band exposed between the jaws.
3. Do not overheat or the temper of the band will be
damaged. Caution - Do not heat beyond the
“blue” stage. If the band begins to show any red
color, it is too hot. Cool quickly by releasing the
anneal button.
WELDER JAWS
12.4.3 BI-METAL BLADES
1. Heat blade slowly by jogging the annealing switch
button until weld just begins to emit light (dull red
color). The desired color may not always be visible in
normal room light - always shade the weld area with
your hand.
2. Cool the weld quickly by releasing the annealing
button.
3. Follow this procedure before and after grinding bimetal blades.
12.5 BLADE GRINDING
!
Keep hands away from rotating grinding wheel.
Failure to comply may cause serious injury. Always
heed the indicator light – when glowing, it warns
that the grinder motor is running.
After annealing, the blade must be ground to remove
excess metal or fl ash from the weld. With the teeth facing
out, grind the weld carefully (Figure 17). Do not hit the
teeth, or grind deeper than the weld, burn, or overheat
the weld area. Be sure to remove fl ash from back edge of
blade. Any fl ash or “stub” teeth which project beyond the
normal set or height of the other teeth must be ground off.
Figure 18 illustrates some unacceptable grindings.

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 workpiece.
5. When the saw has completed about 1/3 of the cut,
increase the feed rate while watching the chip forma tion until cutting is at its most effi cient rate (refer to
“Evaluating Cutting Effi ciency” below). Allow the saw
to complete the cut.
6. The blade is now considered ready for use.
Bad Grindings
12.6 SECONDARY ANNEALING
Anneal the weld 2 to 3 times again after grinding.
12.7 WELDER CLEAN-UP
It is important that the welder jaws be kept clean at all
times. The jaws and inserts must be wiped or scraped
clean after every weld. Doing this will ensure better welds
by:
1. Holding proper alignment.
2. Preventing fl ash from becoming embedded in the
blade.
3. Preventing shorts or poor electrical contact.
Fig. 18
13.0 BAND SAW OPERATION
Consult section 9.0 for identifi cation of the controls.
Unlock the control panel using the provided key.
!
13.2 SETTING BLADE SPEED
1. Refer to Speed and Pitch chart in section 16.0.
Select speed setting for the material to be cut.
2. While machine is NOT running, move gear shift lever
(B, Figure 2) to required speed setting (high or low).
!
Move gear shift lever only when machine is NOT
running, to prevent damage to gearbox.
3. Start saw using the pushbutton.
4. Turn speed setting knob (C, Figure 2) to
required speed. Turning knob clockwise
increases speed; counterclockwise decreases
speed.
Rotate speed setting knob only when machine is
running.
!
Never operate band saw without blade and wheel
covers in place and secured.
13.1 BLADE BREAK-IN PROCEDURE
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 specifi c blades on specifi c materials. The
following procedure will be adequate, however, for break-in
of JET-supplied blades on lower alloy ferrous materials.
1. Use a section of round stock.
2. Operate the saw at low speed. Start the cut with a
very light feed rate.
EVBS-26
13.3 EVALUATING CUTTING EFFICIENCY
The best way to determine whether a blade is cutting effi -
ciently is to observe the chips formed by the cutting.
• If chip formation is powdery, then the feed rate is too
light, or blade is dull.
• If the chips formed are curled, but colored – blue or
straw colored from heat generated during the cut –
then feed rate is excessive.
• If chips are slightly curled and not colored by heat,
then the blade is suffi ciently sharp and is cutting at
its most effi cient rate.
17
14.0 MAINTENANCE
!
Before doing maintenance on the machine, disconnect it from the electrical supply by pulling out the
plug or switching off the main switch. Failure to
comply may cause serious injury.
Use a brush to loosen accumulated chips and debris. Use
a shop vacuum to remove the debris. Make sure the chip
brush on the lower band wheel is properly adjusted.
If the power cord is worn, cut, or damaged in any way,
have it replaced immediately.
Wipe off the rubber tires, and clean the tables after each
day’s use.
14.1 LUBRICATION SCHEDULE
• Upper Blade Guide Shaft – lightly grease weekly.
Clean after each day’s use.
• Speed Change Handle – grease monthly with a
light fi lm on teeth and threads.
• Variable Pulley - insert a light weight grease into
the grease fi tting located on end of pulley shaft.
• Blade Tension Screw – grease monthly.

15.2 MECHANICAL AND ELECTRICAL PROBLEMS
Table 2
Trouble Probable Cause Remedy
Verify machine is connected to power
source. Make sure START button is
pushed in completely, and STOP button is disengaged.
When the band saw overloads on
the circuit breaker built into the motor
starter, it may take time for the machine to cool down before restart.
Allow unit to adequately cool before
attempting restart. If problem persists, check amp setting on the motor
starter.
One cause of overloading trips which
are not electrical in nature is too heavy
a cut. The solution is to reduce feed
pressure into the blade. If too heavy
a cut is not the problem, then check
the amp setting on the overload relay.
Match the full load amps on the motor
as noted on the motor plate. If amp
setting is correct then there is probably
a loose electrical lead.
Verify that band saw is on a circuit of
correct size. If circuit size is correct,
there is probably a loose electrical
lead.
If you have access to a voltmeter, you
can separate a starter failure from a
motor failure by fi rst, verifying incom-
ing voltage at 220+/-10% and second,
checking the voltage between starter
and motor at 220+/-10%. If incoming
voltage is incorrect, you have a power
supply problem. If voltage between
starter and motor is incorrect, you
have a starter problem. If voltage between starter and motor is correct, you
have a motor problem.
Clean motor of dust or debris to allow
proper air circulation. Allow motor to
cool down before restarting.
If electric motor is suspect, you have
two options: Have a qualifi ed elec-
trician test the motor for function or
remove the motor and take it to a
qualifi ed electric motor repair shop
and have it tested.
Machine will not start/restart or repeatedly trips circuit breaker or blows
