and-aft leveling. Be certain you get it level in
BOTH directions.
Set-up and Installation
Preparing the Milling Machine for Service
1. Remove any crating which may be covering the
machine on the pallet.
Mill must be supported equally
under all four corners. Failure to comply may cause
the column to twist and put a bind in the table ways.
2. Remove accessory items from the pallet or
machine table. Compare these items with the list
on the previous page.
10. When the machine is level, secure the base to
the anchor system.
IMPORTANT: Before attempting to raise the mill
head, refer to Mill Head – Left/Right Adjustment in
the Adjustments section for procedures to safely
raise and set up the mill head.
3. Check the tightness of the lifting ring on the ram
to be certain it is tight.
4. Check the tightness of the lock handles on the
ram (see Figure 23) to be certain the ram is
locked tight.
11. Loosen the four hex head nuts (see A, Figure 22)
about 1/4 turn each (counterclockwise), just
enough to allow rotation of the head.
5. Remove the nuts and/or bolts, which secure the
machine to the pallet.
12. While assisting the worm mechanism by putting
upward pressure on the motor by hand, use the
wrench supplied with the machine to turn the
worm nut and raise the head to upright position.
6. Center an overhead crane or other suitable
overhead lifting device and sling arrangement
over the lifting ring.
13. Tighten the headbolts slightly — not torqued —
just snug.
Note: This machine weighs over 2400 pounds!
Be certain the lifting arrangement is new or in
excellent condition and has a safety factor that
will account for age, difficulties in lifting, etc.
When lifting using the ring, the machine will tip
forward. If you wish, you can minimize this tipping
by rigging a support sling over the front of the
machine. Be careful when doing this, to prevent
the sling from damaging any components on the
front of the machine. Be sure to steady the mill to
prevent it from spinning.
14. Using mineral spirits or other cleaning solvent,
clean all of the rust proofing from where it may
have been applied. This is important; moving the
table or any other components before removing
the rust proofing will only put rust proofing where
you don’t want it.
Some of the following steps may have already
been performed on the machine. If so, ignore the
instructions related to those particular steps.
Otherwise, perform them in the order listed,
referring to Figure 11 for any clarification.
7. Lift the machine off the pallet no higher than
necessary to clear the hold-down hardware, then
pull the pallet out of the way. Do NOT get hands
or feet underneath the machine when removing
the pallet!
15. Install the table traverse and cross-feed cranks
on their respective shafts using the nuts on the
shafts to secure the cranks.
8. Put the machine base over the hold-down system
where the machine will be spotted. Anchor bolts
of sufficient size and length must be fastened to
the floor according to the footprint of the mill. See
diagram on page 10.
16. Remove any rust proofing from the drawbar and
its washer, and put the drawbar with washer
installed into the spindle center through the top of
the machine.
17. Slide the fine feed handwheel over the
handwheel hub and push it back until its rollpin
engages the hole in the hub and the wheel is
flush with the hub surface.
Note: The accompanying diagrams show you the
maximum dimensions of the machines with the
table, ram, etc., fully extended in all possible
directions. When spotting the machine be certain
to leave room not only for the machine itself, but
also for operator clearance and clearance for
workers servicing the machine, and any unusual
sizes of workpieces that might extend off the
machine’s table.
18. Put the coarse feed handle on the feed shaft and
tap it lightly until its roll pin engages a hole in the
hub and it is flush against the hub surface.
19. Unwrap and clean the knee crank and install it on
its shaft.
9. When the machine is over its anchors, level the
machine using shims under the corners needing
them. The machinist’s level used for leveling
should be placed on the table. The table is the
reference surface for both side-to-side and fore-
20. Install the rubber way covers at front and behind
the table.

Electrical Connections
Operating Instructions
All electrical connections must
be made by a qualified electrician! Failure to
comply may cause serious injury!
Operating Controls
The lubrication system is a manually operated, oneshot system requiring operator intervention. The
operator must lower the one-shot lever to lubricate
the machine ways and ball screws. The one-shot
lubrication system reservoir is located on the left side
of the machine.
General Electrical Cautions
This machine must be grounded in accordance with
the National Electrical Code and local codes and
ordinances. This work should be done by a qualified
electrician. The machine must be grounded to protect
the user from electrical shock.
The position of the milling machine mill head can be
set up to accommodate the work piece being
machined. The mill head can be set up for angles to
the left or right and for fore and aft angles. The mill
head can also be rotated on its turret. The ram can
be moved back and forth to reach work piece
locations at the fore and aft extremes of worktable
travel. Refer to the Adjustments section.
Wire Sizes
For circuits which are far away from
the electrical service box, the wire size must be
increased in order to deliver ample voltage to the
motor. To minimize power losses and to prevent
motor overheating and burnout, the use of wire sizes
for branch circuits or electrical extension cords
according to the following table is recommended:
Conductor
Length
0 – 50 Ft.
50 – 100 Ft.
Over 100 Ft.
Motor Switch
The Motor Switch is on the upper left-hand side of the
mill head (Figure 5). The switch has three positions:
FWD (forward), STOP, and REV (reverse).
AWG Number
230/460 Volt Lines
120 Volt Lines
No. 14
No. 14
No. 12
Figure 4
No. 14
No. 12
No. 8
Setting the switch to FWD will provide clockwise
spindle rotation. Use FWD for normal, right-hand
tooling.
FWD (clockwise) operation occurs only when the
gearbox is in the low speed position. When the
gearbox is in high-speed position, the motor switch
must be in the REV position to provide right-hand or
clockwise rotation. Refer to Figure 6 for a chart of
required switch positions.
Confirm that power at the site matches power
requirements of the mill before connecting to the
power source.
The motor switch controls a three-phase motor. The
motor can be switched from FWD to REV and back
with the motor running, and will reverse direction
when the switch setting is changed. At higher
speeds, this may put strain on the timing belt but
there will be no damage to the motor or gear
mechanism.
The JTM-4VS has been pre-wired for 230 volt
operation. To change from 230V to the other voltage
offered, remove the junction box cover on the motor
and change the wires according to the diagram found
on the inside of the cover.
Before connecting to the power source, make sure
that the switch is in the off position.
The mill must be properly grounded.
Check for proper spindle rotation in the high-speed
range. The spindle should rotate clockwise when
viewed from the top of the machine. If the spindle
rotates counter-clockwise, disconnect from power
and switch two of the three power leads.
Lubrication
Do not operate the mill before
lubricating the machine fully. Failure to comply
may cause damage to the machine.
Figure 5
Refer to the Maintenance/Lubrication section and
make sure the machine has been fully lubricated
before operating.
11
Figure 6
Variable Speed Control
Change speed only while the
spindle is turning.
The vari-speed handwheel (A, Figure 7) is used to
control the spindle speed. The speeds for high and
low speed ranges are displayed on the panel on the
front of the mill head (B, Figure 7).
All speed changes must be made while the motor is
running. Attempting speed changes without the motor
running can result in damage to the drive
mechanism.
Figure 7
12
Do not move the Quill Power
Feed Lever unless the motor is
at a complete stop. When changing the lever
position, do it gently. If the gear does not engage,
jog the motor and allow it to stop before
attempting to change.
Spindle Brake
The spindle brake lever is located on the upper left
side of the mill head (Figure 8). Pull lever downward
to apply the brake. The spindle brake lever is used
only after the motor switch has been set to OFF. The
spindle will not stop with the motor running.
The quill power feed lever is located on the right side
of the mill head (Figure 10). It is used to engage and
disengage the quill power feed mechanism.
The power feed is engaged by pulling out the knob
and rotating the handle to a new locked position.
When engaged, the power feed mechanism will drive
the spindle upward or downward. The power feed
mechanism will not drive the spindle when the handle
is in the disengage position.
Figure 8
High-Neutral-Low Shift Lever
The mill head can be driven directly (High Speed) or
through the back gear (Low Speed) in the mill head.
The selection is made by changing the position of the
shift lever.
The shift lever is located at the lower right side of the
mill head (Figure 9). The lever position closest to the
operator is the High setting. The lever position away
from the operator is the Low setting. The middle
position is the Neutral setting.
Figure 10
Feed Rate Lever
The Feed Rate Lever (Figure 11) is used to set the
per-revolution rate of the power feed mechanism.
Three feed rates are available: 0.0015-inch, 0.003inch, and 0.006-inch per revolution. The positions are
shown on an indicator plate under the feed rate lever.
Do not shift the High-Low Gear
Lever while the motor is
running. Rotate the spindle by hand to facilitate
changing lever positions.
The rate is selected by pulling out the knob on the
feed rate lever and moving the handle to the detent of
the desired feed rate.
Note: The knob is spring loaded – pull out to rotate to
new position.
Unlike other controls on the machine, the lever shifts
into engagement more easily with the motor running,
and the quill feed lever engaged.
Figure 9
Quill Power Feed Lever
Do not use power feed at speeds
above 3000 R.P.M.
It is recommended to disengage
the power feed worm gear
whenever the power feed is not required. This
avoids unnecessary wear on the worm gear.
Figure 11

Feed Trip Cam Lever
Coarse Feed Handle
The Feed Trip Cam Lever (A, Figure 12) is located on
the left side of the head behind the Manual Fine Feed
Handwheel (B, Figure 12). It engages the overload
clutch on the pinion shaft when positioned to the left.
The Feed Trip Cam Lever stays engaged until Quill
Stop (C, Figure 15) comes in contact with Micrometer
Adjusting Nut (A, Figure 15) forcing it to drop out
automatically, or until it is released manually by
engaging the lever to the right.
The Coarse Feed Handle (A, Figure 14) is located on
the right side of head. The Coarse Feed Handle is
used for non-precision drilling operations and for
moving the quill to a specific depth. A return spring
will retract the spindle automatically once the handle
is released.
Quill Lock Lever
The Quill Lock Lever (B, Figure 14) is located on the
right side of the head. Rotate the handle clockwise to
lock the quill in a desired position. Rotate the handle
counter-clockwise to release.
Figure 12
Feed Direction Control
The Feed Direction Control (B, Figure 13) determines
whether the power feed will move up, down, or not
move at all. The position of the knob depends upon
the direction of spindle rotation (see the Motor Switch
section). The position of the control may be changed
with the system stopped or running. If the control
does not engage easily, move the fine feed
handwheel (A, Figure 13) back and forth to aid
engagement.
Micrometer Adjusting Nut
If the spindle is rotating clockwise, in is downfeed; out
is upfeed. If the spindle rotation is counterclockwise,
out is downfeed; in is upfeed. Neutral position is
between the in and out position.
The Micrometer Adjusting Nut (A, Figure 15) is
located on the front of the head. Use for setting
specific spindle depth. Secure with the lock nut (B,
Figure 15).
It is recommended that the Feed
Direction Knob be left in the
neutral position when not in use.

Note: Due to variables in tool diameter, coatings,
coolant, and materials, no specific spindle speed or
feed rate recommendations are provided. Use
general shop manuals that have data applicable to
the milling and drilling operations being performed.
Or, contact the supplier of the tooling, coolant, and
material for specific recommendations.
IMPORTANT: The power feed can be used for drills
up to 3/8” in diameter (mild steel). Use manual feed
for drills larger than 3/8”.
The overload clutch is factory set
to hold up to 200 lbs. downfeed pressure on the
quill (accommodates drills up to 3/8”). Do not
attempt to adjust clutch pressure.

Draw Bar Operation - Changing Tooling
Adjustments
1. Using the wrench provided with the machine,
loosen the draw bar two or three turns (turn
counterclockwise) using the draw bar hex
(Figure 18).
Mill Head – Left/Right Adjustment
Make sure the machine base is
secured to the floor before repositioning the mill
head. The center of gravity can shift enough to
cause the machine to tip over, resulting in
serious injury to the operator and damage to the
machine.
1. Loosen four large hex nuts that secure the mill
head to the ram adapter (refer to Figure 20).
1/4 turn should be sufficient to allow the head to
move.
NOTE: For angles greater than 10 degrees, use your
free hand to support the mill head, taking some
weight off the brass worm gears. Doing so will greatly
lengthen the life of the worm gears.
Figure 18
2. Tap the top of the draw bar with a soft-faced
hammer to loosen the collet from the taper.
3. Remove the tool from the collet.
4. Insert the tool you are going to use into the collet.
5. Tighten the draw bar firmly using the wrench
provided with the machine. Turn the draw bar.
The tool is now ready for use.
Clamping Work Piece to the Table
1. The worktable has 5/8-inch T-slots for clamping
the work piece to the table.
2. Set motor switch to STOP position.
3. Place the work piece on the table.
4. Clamp the work piece using the T-slot clamps,
studs, and step blocks as required (Figure 19).
Figure 20
2. Turn the worm nut (B, Figure 20) to tilt the head
left or right as required. Use the scale on the ram
adapter to set the desired angle.
Note: The scales on the ram adapter and for
head rotation are guides only. Close tolerance
work will require the use of a dial indicator to
make sure the head is 90° to the table in the X
and Y axis. Please note the table is fitted to be
slightly higher in front, usually about 0.0005”.
Be sure to apply torque in two
steps using a crossing pattern. Failure to do so
could distort the face of the ram adapter.
3. Tighten the four hex nuts. Tighten in two steps
using a calibrated torque wrench. Use a crossing
pattern to tighten the nuts. Tighten initially to 25
foot-pounds.
Figure 19
16
4. Before applying final torque, check to make sure
the mill head is perpendicular to the worktable.
2. Returning to upright position:
a. When returning the mill head to its full upright
position, be sure to support the head by upward
pressure on the spindle as you turn the worm nut.
5. Set up a dial indicator in a collet and secure
using the draw bar (refer to Figure 22).
6. Put the spindle drive in neutral.
b. Check to make sure the mill head is perpendicular to the worktable.
7. Set the dial indicator plunger on the worktable.
Zero the indicator.
c. Set up a dial indicator in a collet and secure
using the draw bar (refer to Figure 22).
8. Rotate the spindle 180 degrees (when rotating,
raise the dial indicator plunger by hand to prevent
it from dropping into the table T-slots).
9. Read the dial indicator. The indicator should read
zero. If not, loosen the four hex nuts and
reposition the mill head.
10. Recheck perpendicularity using the dial indicator.
Repeat the procedure above until the dial
indicator reads zero in both positions.
Be sure to apply torque in two
steps using a crossing pattern. Failure to do so
could distort the face of the ram adapter.
11. Tighten the four hex nuts. Tighten in two steps
using a calibrated torque wrench. Use a crossing
pattern to tighten the nuts. Tighten initially to 25
foot-pounds, then tighten to a final torque of 50
foot-pounds.
Mill Head – Fore/Aft Adjustment
1. Setting the angle:
Figure 22
a. Loosen the three ram adapter clamp bolts on
the ram (A, Figure 21). There is no need to
loosen the bolts more than 1/2 turn to allow
tilting.
d. Put the spindle drive in neutral.
e. Set the dial indicator plunger on the worktable.
Zero the indicator.
f. Rotate the spindle 180 degrees (when rotating,
raise the dial indicator plunger by hand to prevent
it from dropping into the table T-slots).
g. Read the dial indicator. The indicator should
read zero. If not, loosen the four hex nuts and
reposition the mill head.
h. Recheck perpendicularity using the dial
indicator. Repeat the procedure above until the
dial indicator reads zero in both positions.

ram to its ways.
Figure 24
Adjustment of Knee Gib
The knee gib adjustment screw (A, Figure 24) is
located under the chip wiper at the rear of the knee
where it contacts the column. Remove the way cover
and the wiper to expose the gib adjustment screw.
Tighten the screw until a slight drag is felt when
turning the knee crank.
Figure 23
2. Turn the lever (B, Figure 23) to move the ram on
its ways.
Adjustment of Saddle Gib
The saddle gib adjustment screw is on the left front of
the saddle (B, Figure 24). Tighten the screw until a
slight drag is felt when turning the cross-feed crank.
3. When the desired position is reached, lock the
bolts (A, Figure 23) securely.
Positioning the Ram on its Turret
Adjustment of Table Gib
The table gib adjustment screw (C, Figure 24) is on
the left-hand side, beneath the table. Tighten the
screw until a slight drag is felt when turning the
longitudinal table cranks.
Make sure the machine base is
secured to the floor before repositioning the ram.
The center of gravity can shift enough to cause
the machine to tip over, resulting in serious injury
to the operator and damage to the machine.
1. Loosen four turret lock bolts (C, Figure 23) that
clamp the ram to the top of the base. 1/2 turn
should be sufficient to allow the turret to move.
Note: Use gentle hand pressure to avoid rapid
movement.
2. Turn the ram until the spindle is in the desired
position. Use the scale on the turret for degree
measurement.
3. Tighten the four turret lock bolts (C. Figure 23).
Gib Adjustment
The table, saddle and knee are equipped with
adjustable gibs. The gibs may require adjustment if
unusual vibration is noted when the locking
mechanisms are off, or if you experience unusual
vibration when spindle speed, tooth pitch or depth of
cut do not account for the vibration.
NOTE: When adjusting gibs, always start with the
knee first; adjust the saddle second, and adjust the
table last.

power feed. If not, readjust the mechanism until
positive disengagement occurs when the quill is
at the top of its stroke.
Power Feed Trip Lever Mechanism
Refer to Figure 25.
10. Check for correct operation using the coarse feed
handle. If operating correctly, start the drive
motor and engage the power feed mechanism.
Verify that the power feed lever correctly
engages and disengages when driven by the
drive motor.
The power feed trip lever mechanism will need to be
adjusted if worn or whenever any trip lever
mechanism components are replaced.
1. Loosen the feed trip adjusting screw lock nut.
2. Loosen the adjusting screw until it is loose in the
lever and no longer contacts the bottom of the
feed trip plunger.
Table Lead Screw Backlash Adjustment
Refer to Figure 26.
3. Using the coarse feed handle, move the quill to
the bottom of its travel so the quill stop contacts
the micrometer nut. Hold the quill on the stop.
The milling machine table is moved by a lead screw
and nut for each machine axis. For proper operation,
there must be clearance between the lead screw and
the nut, which results in backlash. A second lead
screw nut is provided to eliminate most of the
backlash. The following procedures provide
instructions for obtaining acceptable backlash.
4. Pull the feed handle out to engage the power
feed system.
5. Turn the feed trip adjusting screw until the power
feed disengages.
Cross Feed Backlash Adjustment
1. Use the cross feed crank to move the table to the
extreme rear of its travel.
6. Tighten the feed trip adjusting screw.
7. Release the quill stop so you can engage the
power feed mechanism using the power feed trip
lever.
2. Remove the pleated way cover.
8. Using the coarse feed handle, pull the quill stop
back into firm contact with the micrometer nut.
3. Open the two chip guards enough to expose the
cross-feed adjustment nut (the nut that is toward
the rear of the nut bracket is not adjustable – only
the front nut is adjustable).
4. Loosen the two nut locking screws.
5. Turn the nut slightly to tighten it against the
opposing nut.
6. Tighten the two nut locking screws.
7. Using the cross-feed crank, move the table to the
middle position.
8. Set up a dial indicator to check cross-feed
backlash. Gently move the cross feed crank back
and forth while watching the dial indicator.
Backlash should be between 0.003 inch and
0.005 inch.
9. If necessary, repeat the steps above to set
backlash.
10. Install the pleated way cover.
Longitudinal Backlash Adjustment
Refer to Figure 26.
1. Only one of the longitudinal lead screw nuts can
be adjusted. The other nut is fixed. The left hand
nut is typically adjustable. This can be
determined by looking at the nut from the
underside of the table.
Figure 25
Note: The power feed should disengage when the
quill stop pushes on the micrometer nut. If it does not
disengage, repeat the adjustment steps above.
2. Loosen the two nut locking screws.
9. Engage the power feed and move the quill stop
to the top of its travel. Make sure that the
reverse trip mechanism also disengages the
3. Turn the nut slightly to tighten it against the
opposing nut.

4. Tighten the two nut locking screws.
5. Using the longitudinal table crank, move the table
to the middle position.
6. Set up a dial indicator to check longitudinal
backlash. Gently move the crank back and forth
while watching the dial indicator. The backlash
should be between 0.003 inch and 0.005 inch.
If necessary, repeat the steps above to set backlash.
