Special Warnings when using this Vertical Mill
Using this Vertical Mill may create special hazards.
Take particular care to safeguard yourself and those around you.
1. Electrical Safety. Never operate any tool if there is an electrical hazard. Never
operate an electrical tool in wet conditions. Never operate a tool with an improper

plugged into a properly grounded outlet, which
supplies 220 Volts at 60 Hz. We
recommend you use a circuit which is protected by an appropriate circuit breaker.
2. Ejected Material. Use safe practices to avoid injury from ejected material.
Because the Milling tools and workpieces turn at high speed, there is a danger of
being injured by materials that may be ejected. Always wear ANSI-certified eye
protection. Never attempt to machine any if it is not adequately held. Always stand
to one side of the plane in which the materials are spinning, to avoid being hit if an
is ejected. Never allow bystanders to be in the proximity of the Vertical Mill while in
operation.
3. Entanglement. Use extreme caution to prevent loose materials from being caught
in the machine. Never operate this mill with loose clothing, long hair, jewelry,
or other items which may become caught in the tools or workpieces. In case of
entanglement, press the OFF switch immediately.
NOTICE: No list of warnings can be all inclusive. The operator must supply common
sense, and operate this tool in a safe manner.

INSTALLATION
1. It is important that the machine be located on a hard, solid, level floor. Find a
location that supplies easy access to 220 Volt electrical service. Make sure this
machine is located in a well-lighted and well ventilated area. The floor should be
resistant to vibration.
2. To set the machine on a solid concrete foundation, it’s advisable to apply a little
grout to touch up any unevenness in this concrete in order to get a solid foundation
at all points.
3. When setting machine on a floor that has any surface irregularities, shims should
be used to correct this condition to the greatest extent possible.
PRE-LUBRICATION
1. Thoroughly clean the machine with an appropriate solvent. Do not use gasoline,
kerosene or other flammable liquids.
2. Lubricate all the slide ways with S.A.E. #10 and gears with S.A.E. #30 lubricant. Be
sure the machine is lubricated properly before starting.
LEVELING THIS MACHINE
Before operation, it is critical to level the work table both lengthwise and crosswise,
using a precision level. It will not be possible to maintain accuracy of machined
parts if the mill is not properly leveled to start.

VERTICAL MILLING MACHINE ADJUSTMENTS OF TABLE
FEED TRAVEL
ADJUSTMENTS OF TABLE FEED TRAVEL
Table longitudinal and cross feed can be set for any travel distance by adjusting
the stop set screws that are located in front of table and at the right side of knee.
ADJUSTMENT OF TABLE GIB:
The table is provided with a full length tapered gib in the saddle with an adjusting
screw on each end. To adjust the gib tighten the two screws until a slight drag is felt
when moving the table by hand. If the table is not tight enough, loosen the adjusting
screw on the small end, and tighten up adjusting screw on the big end. If the feel is too
tight, reverse the adjusting procedures.
ADJUSTMENT OF SADDLE AND KNEE GIBS:
To adjust the saddle and knee gibs, use the same method as described above is
used.
CLAMPING TABLE, SADDLE AND KNEE:
When milling with longitudinal table feed only, it is advisable to clamp the knee with
the column and the saddle with the knee to add rigidity to these members and provide
for heavier cuts with a minimum of vibration. The saddle locking lever is located on the
left side of the saddle. Apply moderate clamping pressure, as this will hold the saddle
sufficiently rigid. The table clamping levers are located in front of saddle and should
always be clamped when longitudinal movement is not required. The knee clamping
lever is at the left side of knee. Leave this clamped at all times unless the knee is in
operation.
REMOVING THE TABLE:
Remove the table as follows: hand wheel, dial holder, then bearing bracket. Turn
the lead screw all the way, so that it can be removed. After completing all these steps,
the table can be disassembled easily.
REMOVING SADDLE:
Remove as follows: hand wheel, dial holder, then bearing bracket. Turn the
leadscrew all the way, loosen set screw on the middle of the saddle, take off the lead
screw nut, and draw the saddle gib out. The saddle can then be removed.
Item 40939 For technical questions, please call 1-888-866-5797. Page 8
MOUNTING MOTOR AND SHIFTING BELTS FOR VARIABLE SPEEDS:
The motor is mounted on a plate hinged to the pulley housing. Release the belt
set unit by turning the handle at the side of the motor. Then shift the belts to the proper
speed as desired. Then tighten the belt set unit. A speed change chart is attached inside
the pulley cover.
QUILL LOCK AND VERTICAL FEED:
The handle at the right lower corner of the head is the quill lock. When vertical
feed is not in use, set the handle to lock the quill and make the head more stable. The
micrometer depth stop is graduated in inches. By utilizing these simple graduations, it is
possible to work very accurately to different depths. A lock nut under the micrometer nut
assures that the micrometer nut is secured properly.
QUILL CLUTCH OF VERTICAL MILLING HEAD:
The vertical feed is controlled by a hand wheel at the front of the head and a
handle at the right side of the head. When the hand wheel is in use, tighten the clutch
lock nut by hand, or loosen it for handle operation. Use the hand wheel for fine feeds, or
the handle for fast feeds.
VERTICAL HEAD AND TEE ADAPTER:
The vertical milling head can be tilted 90o on each side by loosening the four
locking bolts on the TEE adapter. By loosening the two set bolts on the adapter, the
vertical milling head can then be swivelled 120O; tighten the set bolts after swiveling.
The motor and milling head must tilt together since the motor and head are suspended
on the same pulley housing.
