will be connected. Use appropriate Lock-Out/Tag-

Out procedures.

After wiring, if saw runs backward, disconnect from
power and switch any two of the three power leads.
Before connecting to power source, be sure switch
is in off position.

7. Replace two 230V fuses with two 460V/1A
fuses (p/n HBS1220MSA-FU1A).

8. Close all covers before starting the saw.

Figure 7-1

8.0 Adjustments

Disconnect saw from power
source before making adjustments, unless
indicated otherwise.

7.1 Voltage conversion

The band saw can be converted from 230V to 460V
operation; consult wiring diagram labels on the
appropriate junction boxes on machine. Diagrams
are also found at back of this manual. (Note: In case
of discrepancy, labels on machine take
precedence.)

Conversion will require additional 460V
components. See your dealer or contact JET to
purchase these items.

1. Make sure saw is disconnected from power
source, or fuses removed or breakers tripped
in the circuit to which saw is being connected.

2. Change incoming power leads into wiring
terminal box on right side of base.

3. Change incoming leads on main motor,
hydraulic motor, and coolant pump, inside the
respective junction boxes.

Open the machine’s electrical panel (refer to Figure
7-1):

4. On the transformer, move R1 wire from 240V to
460V terminal.

5. Replace 230V Overload Relay for Oil Pump

HBS1220MSA-OOP460).

6. Replace 230V Overload Relay for Main Motor
with 460V Overload Relay for Main Motor
(HBS1220MSA-OMM460).

8.1 Removing and installing blade

A general purpose blade has been installed,
tensioned, and tracked on the band saw and should
not require immediate attention. For future blade
replacement, proceed as follows:

1. Raise bow enough for blade to clear table slot.

2. Disconnect machine from power source.

3. Open blade wheel cover (A, Figure 8-1). Make
sure rubber stop at top of bow is properly
adjusted to prevent cover from falling.

4. Remove upper gap cover (B) and lower blade
guard (C).

5. Release blade tension by turning blade tension
handle (D) counterclockwise.

Figure 8-1: installing blade=

8

6. Remove blade from both wheels and out of
each blade guide.

7. Make sure teeth of new blade are pointing in
proper direction of travel. Work blade all the
way up into blade guide bearings (E) and guide
blocks (F) with back of blade against back-up
bearing (G), as shown in Figure 8-2.

Figure 8-2: blade guides

NOTE: If roller bearings need adjustment refer
to sect. 8.5.

8. Position blade through upper slot. Put light
tension on blade and work it onto both wheels.

Make sure back of blade is against shoulder
of both wheels.

9. When you are sure that back of blade is against
shoulder of both wheels and properly inserted
into guides, finish putting tension on blade.

10. Connect power and jog blade on/off button to
be sure blade is in place and tracking properly.
If blade is not tracking properly refer to sect. 8.3.

8.2 Blade tension

Blade tension has been preset by the manufacturer;
if further adjustment is required, or after installing a
new blade, turn handwheel (D, Figure 8-1)
clockwise to appropriate tension for the installed
blade.

8.3 Blade tracking

Blade tracking requires saw to
be operating. Use extreme caution and keep
hands away from moving blade areas.

Blade tracking has been initially set by the
manufacturer. Adjustment is rarely required when
blade is correctly welded and used properly. For
proper blade tracking, the back of blade should be
located against blade wheel shoulder. If it is not,
proceed as follows.

NOTE: Do not hurry tracking adjustments. Patience
and accuracy here will pay off with more accurate
cutting and much longer machine and blade life.

1. Raise bow enough to allow motor to operate.

2. Loosen four knobs and open wheel cover (A,
Figure 8-1). Remove upper gap cover (B,
Figure 8-1), lower blade guard (C, Figure 8-1),
and guide brackets (J, Figure 8-1).

3. NOTE: Maintain proper tension at all times
using blade tensioning mechanism.

4. Loosen center locking screws (H
in all three hex adjustment screws (H

, Figure 8-3)

sure hex adjustment screws do not move while
tightening the center screws.

8. Install the two guide brackets. Position guides
so that bearings just touch the blade. Refer to
sect. 8.5.

9. Install upper gap cover (B, Figure 8-1) and left
blade guard (C, Figure 8-1).

10. Close blade wheel cover (A, Figure 8-1) and
secure with the four knobs.

8.4 Blade guide bracket adjustment

The brackets (J, Figure 8-1) should be set as close
to vise jaw as possible. The right bracket has
minimal adjustment and is set by the manufacturer
to clear the stationary vise jaw. The left bracket can
be moved to accommodate position of floating vise
jaw. Loosen handle and slide bracket into position,
then retighten handle.

8.5 Blade guide bearing adjustment

Proper adjustment of blade guide bearings is critical
to efficient operation of the saw. The blade guide
bearings have been adjusted by the manufacturer.
They should rarely require adjustment except after
a blade change. 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
only very slight clearance between blade and guide
bearings. The bearings will still turn freely with this
clearance. If the clearance is incorrect, the blade
may track off the drive wheel.

Check blade to make sure

welded section is same thickness as rest of
blade. If blade is thicker at weld, the guide
bearings may be damaged.

If required, adjust guide bearings as follows:

1. Disconnect machine from power source.

2. Two bearing guide assemblies are used in each
set of blade guides. The inner bearing guide
assembly is fixed; the outer bearing guide
assembly is mounted to an eccentric shaft and
is adjustable.

3. On the inner bearing guide, hold the bushing
with the 19mm wrench and loosen the center
locking screw with a hex wrench (see Figure 8-

4).

4. Position the bearing by turning the bushing. Set
the bearing in contact with blade then back it off
very slightly so that it will still turn by hand.

5. Tighten center locking screw while holding the

eccentric bushing in position with the 19mm
wrench.

6. The support bearing (see G, Figure 8-2)

prevents deflection of blade under pressure
from the workpiece. Set support bearing so that
it nearly contacts back edge of blade but can
still be turned by hand when blade is not
running.

7. Use knurled knob to tighten carbide guides

against blade. Do not overtighten.

Figure 8-4

8.6 Test cutting to verify adjustment

Test cuts can be used to determine whether or not
you have adjusted the blade accurately. Use 2-inch
round bar stock to perform these test cuts, as
follows:

1. With bar stock securely clamped in the vise,
make a cut through the bar stock (see Figure 8-

5).

2. Mark the top of the bar stock.

3. Move the bar stock about 1/4-inch past the
blade so that you can begin a second cut.

4. Rotate the bar stock 180 degrees so the mark
you made is now at the bottom of the cut.

5. Make a cut through the bar stock.

6. Use a micrometer to measure the thickness
variation of the disk you have cut from the bar
stock. Measure at top and bottom of disk.

The saw blade can be considered correctly adjusted
when the variation measure is no more than 0.012
inch across the face of the disk.

If you do not have a piece of 2-inch bar stock
available for a test cut, use a larger diameter test
piece rather than a smaller one. The maximum
thickness variation on any test piece should be no
more than 0.003 inch, per side, per inch of stock
diameter.

8.8 Broken blade safety device

If blade breaks during operation, the limit switch
shown in Figure 8-7 will automatically stop the
machine.

8.7 Changing blade speed

1. Raise blade approximately six inches above
workpiece and turn feed rate knob to zero.

2. Turn power on, and turn speed adjuster knob
(Figure 8-6) to match appropriate material. Turn
counterclockwise to increase speed, clockwise
to decrease.

Turn speed adjuster knob

only when blade is running.

8.9 Vise adjustments

8.9.1 General movements

1. Place workpiece between vise jaws with
required amount to be cut-off extending out past
blade. (Figure 8-9 shows recommended
positioning of various workpiece shapes within
the vise.)

2. Lift rack block (K, Figure 7-8) and manually
slide floating vise jaw in general proximity to
workpiece. Let block fall to re-engage rack.

3. Model MSA: Rotate handwheel (L) to tighten
jaw against workpiece

Model MSAH: Use vise button on control panel
to tighten jaw.

4. To retract vise jaw, lift rack block and manually
slide floating jaw away (all models), or use vise
release button on control panel (model MSAH
only).

Figure 8-6: blade speed adjustment

3. The indicator on the mechanism shows speeds
in graduations of 90,130,170,235,370 FPM.
The graduations may not match the
recommended feed rate; an approximate speed
may therefore be required. For example, to set
a speed rate of 110 feet per minute, the
indicator would be set about midway between
70 and 130 FPM.

4. Sect. 12.0 shows recommended speeds for
basic materials. Refer to a machinist’s
handbook for more detailed recommendations.

10.3 Blade selection

The HBS-1220MSA/H is provided with a blade
adequate for a variety of jobs on a variety of
common materials. A 4/6 vari tooth bi-metal blade
(5512107) and a 6/10 vari tooth bi-metal blade
(5512108) are also available from JET.

Sect. 12.0 shows recommended speeds for various
materials. These selections, while appropriate for
many shop cutting needs, do not encompass the
wide variety of blades of special configuration (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
tube. In general, the blade choice is determined by
the thickness of the material; the thinner the
material, 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 for hard-to-cut materials such as
stainless steel, tool steel, or titanium, ask your
industrial distributor for more specific blade
recommendations.

Also, the supplier who provides the workpiece
material should be prepared to provide very specific
instructions regarding the best blade (and coolant or
cutting fluid, if needed) for the material and shape
supplied.

10.4 Blade break-in procedure

New blades are very sharp and, therefore, have a
tooth geometry which 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
JETsupplied blades on lower alloy ferrous materials.

1. Clamp a round section workpiece in the vise.
The workpiece should be 2 inches or larger in
diameter.

2. Set the saw on 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 same hydraulic cylinder setting 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
(see sect. 10.5) and allow the saw to complete
the cut.

6. The blade is now considered ready for regular
service.

10.5 Evaluating cutting efficiency

Is the blade cutting efficiently? The best way to
determine this is to observe the chips formed by the
cutting.

If chip formation is powdery, then feed rate is much
too light, or the blade is dull.

If chips are curled, but colored — that is, either blue
or straw-colored from heat generated during the cut
— then feed rate is too high.

If chips are slightly curled and are not colored by
heat, the blade is sufficiently sharp and is cutting at
an efficient rate.

11.0 User-maintenance

Always disconnect power to
machine before performing maintenance,
unless indicated otherwise. Failure to comply
may result in serious personal injury.

Clean up accumulated saw cuttings after use. Make
sure lead screw is kept free of saw cuttings and
other material that would cause damage.

Remove dust or debris from motor fan area with
compressed air or vacuum.

If power cord is worn, cut, or damaged in any way,
have it replaced immediately.

Release tension on blade if saw will not be used for
a time.

Periodically clean chip sludge from cutting fluid
basin.

A handle is provided for
manually lifting bow for servicing purposes. If
bow is raised without the assistance of the
hydraulic controls, use appropriate blocking to
prevent bow from falling. See Figure 11-1.
Failure to comply may cause injury.

11.1 Lubrication

See sect. 11.3, Table 3, for lubrication chart.

All ball bearings are permanently lubricated and
sealed. They require no further attention.

Use a light machine oil to lubricate moving parts as
needed.

Periodically apply light coat of machine oil to
exposed metal surfaces, such as vise bed, to
prohibit rust.

11.1.2 Servicing hydraulic oil

1. Disconnect machine from power source.

2. Remove hydraulic reservoir access panel.

3. Check oil level (A, Figure 11-3). If level is below

yellow (upper) line, the reservoir should be
filled.

4. Disconnect electrical power.

5. Remove reservoir fill cap (B).

6. Add oil up to yellow (upper) line. Install fill cap.

7. If a significant amount of oil must be added,

check for oil leaks in pump components, lines,
and hydraulic cylinder. Correct source of
leakage before operating saw.

8. Connect electrical power. Raise and lower bow

to confirm that saw is operating correctly.

11.1.1 Gear box

Drain and refill gear box according to Table 3
recommendations.

To check gear box oil level, place bow in down
position and wait a few moments for oil to settle.
Check level in sight glass on side of gear casing.
Correct level is dot in middle of sight glass.

To change gear box oil:

1. Connect machine to power and raise bow to
highest position.

2. Unscrew and remove drain plug (Figure 11-2),
and allow lubricant to drain completely. Follow
local regulations for proper disposal of used oil.

Figure 11-2: gear box drain plug

3. Reinstall drain plug.

4. Remove fill plug at opposite side of gear case

11.1.3 Servicing cutting fluid

Pour cutting fluid or coolant mixture into chip tray so
that it drains through strainer into basin. The sight
glass is located on front of base.

Numerous cutting fluids on the market are
formulated for special applications. Consult your
local distributor for details if you have a long range
production task or are required to cut more exotic
materials. Refer to the cutting fluid provider’s
instructions for mixing recommendations and fluid
life span.

To drain cutting fluid, use drain plug located on left
side of machine base, near pump access panel.
Follow local regulations when disposing of used
machine fluids.
