8.0 Electrical connections

Plug the saw into a suitable service branch. The
saw is a 120V single phase motor and the motor
cable has a standard 3-prong grounded plug
installed.

Always connect the plug to a

grounded branch circuit.
If local regulations require that the saw be

permanently wired, or if the environment in
which the saw is used makes this advisable,
the connection should only be made by a
licensed electrician who is familiar with all
national and local electrical codes.

The service disconnect should have an external
ON/OFF switch or lever which permits the saw
operator to disconnect branch power to the
saw during set-up and maintenance operatio ns
as described in this manual.

9

8.1 Wiring diagram

The motor standard on the saw is a 120V single
phase, 1750RPM motor which can also be
reconfigured for 240V operation. If the saw will be
used on a 240V single phase branch circuit, the
electrician will find a diagram for reconfiguring the
motor wiring underneath the motor terminal plate.

The wiring diagram here is included for reference
when replacing the motor, ON/OFF switch or cable.
These operations should be performed only by a
licensed electrician.

Figure 8: Wiring diagram

for cutoff work, use the following procedure to
check the blade-to-jaw angle.

1. Disconnect the saw from its electric power
source.

2. W ith the saw arm in its fully lowered position,
place a machinist's square,or a machinist's
protractor 90 degrees, against the saw blade
and right vise jaw. If the jaw is square to the
blade, then no adjustment is required.

3. If adjustment is required, see Angle Cutting.
The procedure for setting the jaw angle with
respect to the blade is described in that
section.

9.3 Angle cutting

Refer to Figure 9.

1. Loosen the right jaw pivot and lock bolts.

2. With t he arm i n its f ully lowe red pos ition, and
using a machinist's protractor between the saw
blade and right vise jaw, set the angle of the
right jaw to the required angle.

9.0 Operating Instructions

9.1 Clamping materials in the vise

Refer to Figure 1.

1. Lift the saw arm to its full up position.

2. Lock the arm up using the hydraulic feed
control valve.

NOTE: Use the handle on the arm to lift the
arm. Never use any other part of the arm as a
lifting method.

3. Open the left vise by turning the vise
handwheel counterclockwise.

4. Adjust the vise jaws f or the appropriate cutting
angle, if required. See sections on Right angle
cutting and Angle cutting.

5. Put the work piece material between the vise
jaws.

NOTE: If the work piece material is long,
support both the ends of the material as
needed to keep the material level on the saw
base.

6. Turn the vise handwheel clockwise until the
work piece is securely clamped in the vise.

7. Proceed to cut according to instructions in
Cutting procedure.

9.2 Right angle cutting

Refer to Figures 1 and 9.

If you want to be certain the workpiece is being
held in the vise at exactly 90 degrees to the blade

3. Tighten the pivot and lock bolts.

Figure 9: Using a protractor to set the vise jaws at
desired angle. By setting the protractor to 90
degrees, or using a machinist's square, the jaws
can also be set square with respect to the blade.

4. Lift the saw arm to its full up position and lock
it up using the hydraulic feed control knob.

NOTE: Use the handle on the arm to lift the
arm. Never use any other part of t he arm as a
lifting method.

5. Loosen the left jaw lock bolt.

10

6. Use the handwheel to move the left j aw until it
touches the right jaw firmly.

7. S nug the left jaw lock bolt. Both vise jaws are
now the correct angle for the required cut.

NOTE: There is a scale on the back of the saw
table which allows you to set up for angle cuts
without using a protractor. See Figure 10.
These angles should be considered
approximate, and the protractor method should
be used where higher accuracy is required.

Figure 10: Using the scale on the rear of the saw
base to set the jaws for angle sawing. Where the
edge of the right jaw crosses the scale an
approximate angle cut can be made to the
indicated number of degrees on the scale.

9.5 Using the stock stop

When cutting a number of identical pieces, the use
of the stock stop can speed operations.

Refer to Figures 1 and 12.

1. Disconnect the saw from its electric power
source.

2. With the arm in its fully lowered position,
loosen the stock stop set screw.

3. Slide the stock stop to the required distance
from the blade.

4. Rotate the stock stop so the stop is at the
lowest possible position for stoppi ng the work
piece at the required distance. This will help
prevent any binding between the work piece
and blade when the cut is completed.

5. Tight en the st o c k sto p se t sc r e w secure l y.

6. For best accuracy, make a test cut on a piece
of scrap material to verify the length of cut
using the stock stop.

9.4 Clamp ing met hods

The method for clamping different cross-section
work pieces is shown in Figure 11.

9.6 Blade selection

The saw is delivered with a blade adequate for a
variety of jobs on a variety of common materials.
However, JET's blades, while appropriate to many
shop cutting needs, don't begin to exhaust the wide
variety of special blades available for special
cutting jobs.

For high production cutti ng of special materials, or
for hard-to-cut materials such as stainless steel,
tool steel, titanium, etc., ask your industrial
distributor for more specific blade
recommendations.

9.7 Changing blade speeds

1. Refer to Table 2 for recommendations on
blade speed for various materials.

Note: These are approximate speeds.
Different alloys and section materials and the
use of cutting fluid may require other speeds.
Check your machinists' handbook, or ask for
recommendations from your blade, cutting fluid
or work piece suppliers for specific
recommendations on specific material.

2. Disconnect the saw from its electrical power
source.

3. With the arm in its fully lowered position,
remove the pulley cover lock screw and open
the pulley cover. Refer to Figure 13 for
speeds and belt positions.

Figure 13: Blade speeds and belt positions

4. To change the belt position (and, therefore, the
blade speed) first loosen the motor plate
adjustment lock nut. Refer to Figure 14 for the
position of the motor plate adjustment screw
and locknut.

9. Reestablish electrical power to the saw and
proceed with cutting.

9.8 Evaluating cutting efficiency

Is the blade cutting efficiently? The best way to tell
is by observing the chips form ed by the blade as it
cuts.

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

If the chips formed are curled, but straw or blue
colored, then the feed rate is too high.

If the chips formed are curled but not colored, then
the blade is sharp enough and cutting at an
efficient rate.

9.9 Cutti ng procedure

1. Never start a cut with the blade resting o n the
work piece.

2. Be certain you knock off the sharp corners of
any work piece material which might damage
the blade. See Figure 11.

3. Have the motor ON and running at full speed
before lowering the blade into the cut.

4. Use the hydraulic control valve to feed the
blade into the work piece.

5. If you use a cutting fluid, turn the valve on
before beginning the cut.

Figure 14: Motor plate adjustment screw

5. Turn the adjustment screw counterclockwise
until the belt can be move to the pulley position
required.

6. Turn the adjustment screw clockwise to
tension the belt until there is 1/2 inch of pla y in
the belt as shown in Figure 15.

Figure 15: Setting correct play in drive belt

7. Tighten the adjustment lock nut.

8. C lose the pulley cover and secure it shut with
the lock screw.

9.10 Using the hydraulic feed control

Refer to Figure 16.

The hydraulic feed control cylinder is a "single
action" hydraulic cylinder. This allows you to lift
the arm at any time, easily, but controls the
downward movement of the arm using a valve on
the top of the cylinder.

Figure 16: Hydraulic feed control

When the control valve is turned fully clockwise the
cylinder is "locked" and the saw arm will not move

12

downward. You can lock the arm, using the valve,
at any position in its tra vel. Thi s allows yo u to lock
the arm in its up position for operations which
require it. And it allows you to lock the arm in
positions which allow you to adjust work piece
length, etc.

Most important, use of the valve allows you to
begin any cuts "gently," which can greatly extend
the life of the blade. Simply ope n the val ve slightly
to begin the cut, then open the valve to effective
cutting feed. See Evaluating cutting efficiency.

The valve is also important when breaking in any
new blades. See Blade break-in procedures.

9.11 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. You may want
to consult manufacturers' literature for break-in of
specific blades on specific materials. However, the
following break-in procedure will be adequate for
break-in of JET supplied blades.

1. Clamp a 2 inch or larger work piece in the saw.

2. Set the blade speed to its required speed.
See Changing blade speeds.

3. If possible, use a cutting fluid during break-in
cuts.

4. Set the hydraulic control valve just enough to
begin a very light cut on the work piece.

5. When the blade has cut 1/3rd of the way
through the work piece, increase the feed rate
slightly and allow the blade to complete the
cut.

6. Make another cut on the stock. B egin the cut
with the control valve set at the same feed rate
you finished the first cut.

2. Lift the saw arm to its full up position and lock
it up using the hydraulic feed control knob.

NOTE: Use the handle on the arm to lift the
arm. Never use any other part of the arm as a
lifting method.

3. Remove the blade guard cover thumb screw
and open the cover.

4. Loosen the blade te nsion knob until the blade
comes off of its wheels.

5. Using leather gloves to protect from cuts, slip
the blade out of the blade guide bearings and
off of the saw.

6. Examine the drive and idler wheels for
evidence of wear on the flanges. If the fla nges
are wearing, the blade is misadjusted. See
Blade tracking for correcting this condition.

7. Put a replacement blade in the blade guide
bearings and loop the ends of the blade o ver
the drive and idler wheels.

NOTE: The saw blade teeth must poi nt in the
direction of travel. See Figure 17.

8. Use the blade tension knob to put tens ion on
the blad e until it no longer s l ip s o n the w heels.

NOTE: Do not overtighten the blade. Just
increase tension until the blade does not slip
on the wheels.

9. Close the blade guard cover and replace a nd
tighten the thumb screw.

10. Reconnect the saw to its electrical power
source.

7. 1/3rd of the way through the second cut,
increase the rate of feed until the blade is
cutting at its most efficient rate. See Evaluating
cutting efficiency.

8. Allow the saw to complete this second cut.
The blade can now be considered ready for
regular service.

Note: There are flanges on the back face of the
drive and idler wheels to prevent the blade from
"walking off" the back of the wheels. If these
flanges are damaged the wheels must be replaced.
Check blade tracking whenever changing a blade
to be certain the blade is positioned correctly on
the wheels. See Blade tracking in the Maintenance
section of this manual

9.12 Changing blades

1. Disconnect the saw from its electric power
source.

Figure 17: Corrrect tooth direction when replacing
blade.

9.13 Adjusting blade guides

Refer to Figure 1.
Both the left and right blade guides should be

positioned as close as possible to the left and right
edges of any work piece being cut. This provides
support to the blade so it can make a straight cut.

1. Loosen the blade guide knobs.

2. Slide the blade guides to the correct spacing.

3. Tighten the lock knobs securely.

13

10.0 Maintenance

NOTE: The following maintenance operation
requires the services of a licensed electrician.

3. While holding the shaft from turning, tighten

4. Pull the pulley off of the motor drive shaft.

5. BEING CERTAIN THAT THE SA W HAS BEEN
SAFELY DISCONNECTED FROM THE
SERVICE BRANCH, open the motor terminal
cover and remove the three wires which
connect it to the power cable.

6. Remove the four nuts, bolts and washers
which hold the motor to its mounting plate.

7. Remove the motor from the saw.

8. Reinstall the replacement motor and pulley by
reversing steps 7 through 4, above.

9. Loosen the motor mounting plate adjustment
screw so the screw puts no tension on the
plate.

10. Adjust the position of the motor so that:

1. If the blade is fully tensioned, release tension
slightly while performing the tracking
operation.

2. If the blade is not on slow speed, change to
the slowest speed according to instructions in
Changing blade speeds.

3. Lift the saw arm to its full up position and lock
it using the hydraulic feed control knob.

NOTE: Use the handle on the arm to lift the
arm. Never use any other part of the arm as a
lifting method.

4. Rem ove the thumb screw and open the blade
guard cover. Prop it open so you can have
access to the idler wheel.

5. Refer to Figure 18. Use a wrench to loosen
bolt A, a small amount.

A. the pulleys are parallel with each other, and
B. the drive belt can just be installed o ver the

pulleys (It may be necessary to adjust t he
drive pulley along the motor shaf t to make
the pulleys parallel.)

11. Tighten the motor mounting bolts securely.

12. Tighten the pulley set screw securely.

13. Install the drive belt.

14. Tension the drive belt and complete the
replacement task by performing instructio ns 6
through 9 in Changing blade speeds.

10.2 Adjusting guide bearings

The outside guide bearing on each of the bearing
seats is mounted on an eccentric shaft to allow
adjustment of the bearing clearance between
bearings and blade, as follows:

1. Loosen the guide bearing shaft lock nut.

2. Use an open end wrench on the hex flats
underneath the guide seat to adjust the
eccentric shaft so the bearing holds the blade
vertically against its opposing bearing. Over­tightening the blade between the bearings will
only shorten bearing life. Adjust the bearings
so blade is just held firmly in vertical position.

Figure 18: Blade tracking mechanism

6. Turn the saw motor ON.

7. In sert a hex wr enc h into the se t scr ew, B, and
turn it slightly while observing the tracking
action of the blade on the idler wheel. Turning
the hex wrench clockwise will make the blade
track toward the wheel flange. Turning the
wrench counterclockwise will make the blade
track away from the flange.

8. Adjust the set screw in very small amounts
until the blade just starts to track toward the
flange.

9. As you adjust the blade toward the flange,
insert a strip of paper between t he blade and
wheel as shown in Figure 19.

Use a strip of paper six

inches long or longer so your hands stay
clear of the moving parts of the saw.

14

Figure 19: Checking blade tracking

10. Keep using small amounts of adjustment to
move the blade toward the flange, testing with
the paper strips, until the paper is cut between
the blade and flange.

11. When the paper is cut, turn the hex wrench
slightly in the opposite direction so the blade
does not track while touching the flange.

12. Tighten bolt A.

Figure 20: Adjusting back-up bearings

13. Check with a paper strip to be certain the
blade has not moved back into contact with the
flange. Readjust, if necessary.

14. Using the blade tension knob, reapply tension
to the blade so it does not slip on the wheels.

15. Turn the saw OFF.

16. Close the blade guard cover and install and
tighten the thumb screw.

to the shaft.

3. Press off the bearing.

4. Press on the new bearing and secure it with
the snap ring.

5. Reinstall the blade according to instructions 6
through 10 in Changing blades.

6. Adjust the bearing spacing according to
instructions in Adjusting guide bearings.

10.5 Adjusting back-up bearings

Refer to Figure 20.

1. Disconnect the saw from its electrical power
source.

2. Loosen the guide bearing seat retaining bolt.

3. Slide the bearing seat as necessary until the
back-up bearing just touches the back edge of
the saw blade.

4. Tighten the guide bearing seat retaining bolt.

10.6 Adjusting the arm stop

adjustment bolt

Refer to Figure 1.

1. Lower the arm to its fully lowered position.
The saw blade should be level and the cutting
edge of the blade should be in t he relief slot,
below the level surface of the saw base. If this
is not the case, adjust the arm height as
follows:

2. Loosen the leveling bolt lock nut.

3. Adjust the leveling bolt until it supports the arm
and blade correctly as described above -- level
and below the top of the saw base.

4. Tighten the leveling bolt lock nut.

10.7 Adjusting motor switch actuator

This task should be performed whenever the arm
stop adjustment is corrected or whenever the saw
is turning off incorrectly .

Refer to Figure 1.

1. Raise the arm until the switch actuator is not in
contact with the switch.

2. Turn the switch ON.

3. Open the hydraulic control valve so the arm
moves slowly downward.

4. The motor switch should shut off just as the
arm contacts its horizontal stop bolt and the
blade is fully below the blade relief in the saw
base. If the motor shuts of f too soon, or not at
all, adjust the switch actuator by bending it, as
required, to correct the fault condition.

5. Restore electrical power to the saw.

to instructions in Adjusting back up bearing
clearance.

10.9 Adjusting the bearing guide

seats for blade vertical

1. Install a new blade according to instructions in

sect. 9.12.

2. Adjust the guide bearings according to
instructions in sect. 10.2, Adjusting guide
bearings.

3. Adjust the back-up bearing according to
instructions in sect. 10.5, Adjusting back-up
bearings.

4. W ith the arm in its full horizontal position and
the blade guides moved apart to clear the
widest possible cutting area, clip a scale to t he
blade, to provide a vertical reference surface.

5. Place a machinist's square on t he saw base,
against the scale. See Figure 21.

10.10 Test cutting to verify

adjustment accuracy

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

1. With the bar stock securely clamped in the
vise, make a cut through the bar stock. (See
Figure 22.)

2. Mark the top of the bar stock.

3. Move the bar stock about 1/4 inch past the
blade so 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 between the top and bottom of the
disc yo u have cut f rom the bar stock . Unle ss
things are truly perfectly aligned, there is
almost certain to be a certain amount of
"wedge" to the shape of the di sc you have c ut.
The saw blade can be considered correctly
adjusted when the variation measured is no
more than .012 inch across the face of the
disc. If you do not have a 2 inch bar stock

available f or a test cut, use a larger diameter
test work piece rather than a smaller one.
The maximum thickness variation on any
test piece should be no more than .003
inches, per side, per inc h of stock diam eter.

Figure 21: Adjusting the saw blade for vertical. Be
sure to do this operation on both of the bearing
guide seats so the blade is perfectly vertical along
its entire exposed cutting surface.

6. Loosen the guide bearing seat attachment bolt
slightly and, using a wrench on the bearing
seat, adjust the angle of the seat so the blade
is vertical. (There is a small amount of side
