1.0 IMPORTANT SAFETY

INSTRUCTIONS

WARNING – To reduce risk of injury:

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 ANSI Z87.1 approved safety
glasses or face shield while using this band
saw. (Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.)

7. Before operating this machine, remove tie,
rings, watches and other jewelry, and roll
sleeves up past the elbows. Do not wear loose
clothing. Confine long hair. Non-slip footwear or
anti-skid floor strips are recommended. Do not
wear gloves.

8. Wear ear protectors (plugs or muffs) if noise
exceeds safe levels.

9. Make certain the switch is in the OFF position
before connecting the machine to the power
supply.

10. Make certain the machine is properly grounded.

11. Make all machine adjustments or maintenance
with the machine unplugged from the power
source.

12. 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.

13. 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
completion of maintenance.

14. 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.

15. Provide for adequate space surrounding work
area and non-glare, overhead lighting.

16. Keep the floor around the machine clean and
free of scrap material, oil and grease.

17. Keep visitors a safe distance from the work
area. Keep children away.

18. Make your workshop child proof with padlocks,
master switches or by removing starter keys.

19. Give your work undivided attention. Looking
around, carrying on a conversation and “horse­play” are careless acts that can result in serious
injury.

20. Maintain a balanced stance at all times so that
you do not fall into the blade or other moving
parts. Do not overreach or use excessive force
to perform any machine operation.

21. 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.

22. Use recommended accessories; improper
accessories may be hazardous.

23. Maintain tools with care. Keep saw blades
sharp and clean for the best and safest
performance. Follow instructions for lubricating
and changing accessories.

24. Maintain proper adjustment of blade tension,
blade guides and thrust bearings.

25. Turn off the machine before cleaning. Use a
brush to remove chips or debris — do not use
your hands.

28. Remove loose items and unnecessary work
pieces from the area before starting the
machine.

2

29. Never hand hold the material. Always use the

g

vise and clamp it securely.

30. Be sure that blade is not in contact with
workpiece when motor is started. Allow motor to
come up to speed before bringing blade into
contact with workpiece.

31. Avoid contact with coolant, especially guarding
your eyes.

32. Never reach around or over saw blade during
operation. Keep hands and fingers away from
blade area.

33. Do not remove jammed pieces until blade has
stopped.

34. Don’t use in dangerous environment. Don’t use
power tools in damp or wet location, or expose
them to rain. Keep work area well lighted.

35. 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 2 (sect. 6.3) shows 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.

Read and understand all

assembly instructions before attempting
assembly. Failure to comply may cause serious
injury.

5.0 Setup and assembly

Disconnect band saw from

power during setup.

5.1 Shipping contents

5. Adjust leveling screws until machine is level in
both directions and tighten nuts against the
base flanges.

6. Install material stop into front hole in table, as
shown in Figure 7-10.

7. Fill coolant reservoir with 15L (4 gal.) of
appropriate coolant, by pouring it through the
filter screen atop the pan.

8. Install splash plate over lip of base and below
cutting area. This deflects coolant and chips
down into the base.

1 Band saw
1 Splash plate
1 Tool box containing:
6 Leveling pads
1 Set of open-end wrenches
1 Set of hex wrenches
1 Cross-point screwdriver
1 Adjustable wrench, 12 in.
6 Hex cap bolts, 1/2-20 x 2in.
6 Hex nuts, 1/2in.

5.2 Unpacking and cleanup

1. Finish uncrating saw and inspect for damage.
Should any have occurred, contact your local
distributor. Do not discard any packing material
until saw is set up and running properly.

2. Remove all bolts attaching machine to shipping
pallet. (The wood support beam can be
removed after machine has been connected to
power and the bow raised.)

3. Clean all rust protected surfaces with a cleaner­degreaser or kerosene to remove protective
coating. Do not use gasoline, paint thinner,
mineral spirits, etc. These may damage painted
surfaces.

4. Lubricate all slideways with SAE 10W oil.

5. Compare contents of shipping carton with the
contents list in this manual. Report shortages, if
any, to your distributor.

5.3 Installation

1. The band saw should be located on a solid and
level foundation, preferably concrete. Allow
room for bow swiveling, servicing and for
moving large stock around the machine.

2. Use lifting straps that are isolated from the band
saw’s finished surfaces and knobs, to move
machine to desired location. Position straps
under secure areas; do not strap bow or vise
assembly.

3. Install leveling bolts/nuts/pads, and the leveling
feet as desired, through the base flanges.

4. Place a level on the table surface and check
side-to-side and front-to-back.

6.0 Electrical connections

Electrical connections must be

made by a qualified electrician in compliance
with all relevant codes. This machine must be
properly grounded to help prevent electrical
shock and possible fatal injury.

The MBS-1323EVS-H Horizontal Band Saw is wired
for 3-phase, 230V; the MBS-1323EVS-H-4 is wired
for 3-phase 460V. The machine is not provided with
an electrical plug; you may either attach a proper
UL/CSA-listed plug, or “hardwire” the machine
directly to a service panel.

It is recommended that the band saw be connected
to a dedicated 20 amp circuit with circuit breaker or
time-delay fuse marked “D”. Local codes take

precedence over recommendations.

Before connecting to power source, be sure switch
is in off position.

6.1 GROUNDING INSTRUCTIONS

This tool must be grounded. 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 equipment-grounding
conductor. If a plug is used, it must be plugged into
a matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.

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
equipment-grounding 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. Failure to comply may cause serious
or fatal injury.

8

If hardwired:

Permanently connected tools: This tool should be
connected to a grounded metal permanent wiring
system; or to a system having an equipment­grounding conductor. Make sure a disconnect is
available for the operator. During hard-wiring of the
machine, make sure the fuses have been removed
or the breakers have been tripped in the circuit to
which the drill press will be connected. ALWAYS
FOLLOW PROPER LOCK-OUT/TAG-OUT PRO­CEDURES.

6.2 Extension cords

The use of extension cords is discouraged; try to
position equipment within reach of the power
source. If an extension cord becomes necessary, be
sure it is 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 2 shows recommended size to use depending
on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.

should place light pressure on blade. Do not
overtighten.

If tension mechanism will not move blade, loosen
and then re-tighten socket head cap screws on gibs
(X, Figure 7-3).

7.4.2 Tracking

Tracking is performed with
wheel covers open and blade moving. Use
extreme caution so that you do not come into
contact with blade.

Blade tracking has been set by manufacturer.
Adjustment is rarely required when blade is used
properly and is correctly welded.

Tracking is set properly when back of blade lightly
touches shoulder of wheels. Note: Over-tracking
(allowing blade back to rub hard against wheel
shoulder) may damage blade wheels and blade.

If blade is not tracking properly:

1. Raise bow enough to allow saw motor to

operate.

2. Open wheel cover and remove left blade guard.

3. Back off left and right bearing guide assemblies.

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

4. Loosen center locking screws (O, Figure 7-4) in

all three hex adjustment screws (P) on
tensioning mechanism.

Figure 7-3: carbide guide adjustment

7.4 Blade tension and tracking

Refer to Figure 7-4.

7.4.1 Tension

Blade tension has been set by manufacturer at
approximately 1800 kg/cm2 (25,000 psi) for the
supplied blade. Turn handwheel (C, Figure 7-4)
clockwise; if collar (N) slips out of position, then
blade is properly tensioned. Continue turning
handwheel until collar re-engages. NOTE: Simply
turn handwheel, do not press on it.

Figure 7-4: blade tension and tracking

While performing the
following, keep blade from excessively
rubbing on wheel shoulder, which may
damage wheel and/or blade.

5. Start saw. Slowly turn single hex adjustment
screw (P

) to tilt idler wheel. Do not turn either

1

of the other two adjustment screws. Turn
adjustment screw until blade is touching
shoulder of idler wheel.

NOTE: Turning screw inward causes blade to
move toward wheel shoulder. Turning screw
outward causes blade to move away from
shoulder.

10

6. Turn single hex adjustment screw (P1) so blade
starts to move away from wheel shoulder. Then
immediately turn single hex adjustment screw in
opposite direction so that blade stops, then
moves slowly toward shoulder.

Keep fingers clear of blade

and wheel to avoid injury.

7. Turn single hex adjustment screw (P

) to stop

1

motion of blade on wheel as it gets closer to
wheel shoulder. Put a 6-inch length of paper
between blade and wheel. The paper should
not be cut as it passes between wheel shoulder
and blade.

8. Turn single hex adjustment screw (P

) a small

1

amount. Repeat insertion of paper between
wheel shoulder and blade until paper is cut in
two pieces. NOTE: You may have to repeat the
check with the paper several times before blade
and shoulder cuts paper into two pieces. Do not
hurry this adjustment; patience and accuracy
here will pay off with better, more accurate,
quieter cutting and much longer machine and
blade life.

9. When the paper is cut, turn hex adjustment
screw (P

) slightly counterclockwise. This

1

assures that blade is not rubbing excessively
against wheel shoulder.

10. Shut off saw.

11. Hold hex adjustment screws (P, P

) with a

1

wrench and tighten center locking screws (O).
Make sure hex adjustment screws do not move
while tightening center screws.

12. Adjust left and right bearing guide assemblies.
See sect. 7-3.

13. Install left blade guard and close wheel cover.

Coolant pump must be
submerged before operating to prevent damage
to pump.

The blade guides are fitted with coolant valves.
Coolant is provided to the fittings through
interconnecting tubing, and is dispensed directly
onto saw blade.

Adjust coolant flow valves to provide desired flow.
The flow should be no more than blade can draw
into the workpiece by its movement through the
material.

The coolant flow can be stopped in two ways: Turn
off coolant pump switch on control panel, or close
coolant flow valves.

9.0 Operation

9.1 Automatic shut-off

9.1.1 Cut completion

Limit switches (A, Figure 9-1) control bow
movement. Saw must automatically shut off when
cut is completed. The switches are pre-set by the
manufacturer, but can be adjusted if needed.

Figure 9-2: blade break sensor

9.2 Auxiliary coolant hose

The saw is equipped with auxiliary coolant hose and
spray nozzle. This can be used to direct greater
volume of coolant at workpiece, or for washing off
table area.

9.3 Prior to Operation

1. Check that blade tooth direction matches

diagram on blade guard, and blade guides are
properly set.

2. Check to see that blade is properly seated on

wheels after applying correct tension
(approximately 25,000 lbs.).

3. Select proper speed and feed rate for material

being cut.

4. Material to be cut must be securely held in vise.

5. Check to see that coolant level is adequate and

turn on coolant pump if material to be cut
requires it. Machine should be filled with
approximately 23L (5.2 gal.) of proper coolant
mixture. Follow directions on product maker’s
label and fill coolant tank through chip tray area.

6. Do not start cut on a sharp edge.

7. Keep machine lubricated. See sect. 10.2.

Figure 9-1: auto shut-off switch

9.1.2 Blade breakage

If the blade breaks during operation, a sensor near
drive wheel will shut off the saw (Figure 9-2).

9.4 General operating procedure

All blade covers and machine

guards must be in place and secured before
turning on band saw.

1. Select proper speed on digital readout for type

of material to be cut.

2. Raise bow high enough to clear workpiece.

Make sure blade is not in
contact with workpiece when motor is
started.

3. Place stock between vise jaws, set stock for
desired width of cut and tighten vise. (See
Figure 9-3 for recommended placement in vise
of varied workpiece shapes.)

13

4. Make sure left blade guide post is adjusted as
close as possible to left vise jaw.

5. Select auto or manual mode.

6. Start motor and allow machine to reach
operating speed.

7. Turn on coolant and adjust coolant valves as
desired.

8. Turn feed rate control knob for desired rate,
then press blade descent button. Allow blade to
slowly enter workpiece.

9. Blade will stop running at completion of cut,
whether in auto or manual mode.

IMPORTANT: In manual mode, bow will remain
in down position – select up direction with
switch (D, Figure 8-1) to raise bow. In auto
mode, after cut completion bow will rise to
original position.

9.6 Blade selection

The saw is provided with a blade that is adequate
for a variety of cut-off jobs on a variety of common
materials.

See Table 3 for 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 work
piece 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 to work 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.

Figure 9-3

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

If chips formed 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 — blade is sufficiently sharp and is cutting at
its most efficient rate.

9.7 Blade break-in procedures

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
JET-supplied 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 saw on low speed. Start cut with a very light
feed rate.

3. When saw has completed 1/3 of cut, increase
feed rate slightly and allow saw to complete the
cut.

14

4. Keep the same settings and begin a second cut
on the same or similar workpiece.

5. When blade has completed about 1/3 of cut,
increase feed rate. Watch chip formation until
cutting is at its most efficient rate (sect. 9.5) and
allow saw to complete the cut. The blade is now
considered ready for regular service.

10.0 User-maintenance

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

10.1 General cleaning

Keep wheels clear of chips and debris.

Keep slide areas (such as vise ways and T-slot,
slide for bow swivel, and behind the scale where the
guide posts slide) clean and oiled.

Keep a light coat of SAE 10W oil on machined parts
to inhibit rust.

Keep proximity switches and sensors clear of dirt or
dust.

10.2 Lubrication

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

Coolant – Maintain proper coolant level. Clean chip
sludge from coolant tank as needed. Replace
coolant on a frequency appropriate to type of
coolant being used. Oil-based coolants can sour.
Refer to coolant supplier’s instructions for
frequency.

Hydraulic cylinder pivot – apply a light oil every 6
months.

Blade tension screw – grease every 6 months.

Wire brush bearing – apply a light oil monthly.

10.2.1 Hydraulic system

10.2.2 Gearbox

The gearbox has been pre-filled by the
manufacturer. After first 50 hours of use the gearbox
should be drained and refilled. After that change oil
every six months.

1. Remove drain plug (A, Figure 10-1) and allow
lubricant to drain completely. Reinstall drain
plug.

2. Remove oil fill plug (B) and fill gearbox with 1
liter (1 qt.) of Mobil
equivalent. Replace fill plug.

SHC 634 gearbox oil, or

Figure 10-1

10.3 Belt replacement

To remove belt, loosen knob and remove tension on
belts (see Figure 7-5). Slip old belts off pulleys and
install new belt. Readjust tension and tighten knob.

NOTE: It is recommended that both belts be
replaced at same time.

New belts may stretch slightly as they get broken in,
so belt tension should be re-checked after a period
of use.

10.4 Additional servicing

Any additional servicing should be performed by
authorized service personnel

11.0 Optional accessory

The hydraulic oil tank has been prefilled by the
manufacturer. Check oil level in sight glass (Figure
7-7). If oil needs to be added, pour through fill plug
hole. Use Mobil™ Hydraulic Oil series AW68 or
equivalent.

An optional Roller Stand (part no. 413413) is
available for the MBS-1323EVS band saw. Contact
your dealer or visit our website for more information.
