Safety Instructions
This machine is electrically powered.To avoid electric shock:
• Do not use it in or near water.
• Make sure electrical plug is securely plugged into wall outlet.
• Make sure plug grounding pin is in place and socket is properly grounded.
For personal safety:
• Avoid loose-fitting clothing that can catch in the machine's rotating parts.
• Remove chuck keys and wrenches before turning on the machine.
• Make sure all tooling is securely attached to the machine and rotates properly.
• Make sure all workpieces are securely clamped to the table and/or
tightly held in a vise which, in turn, is properly mounted.
• Make sure the machine is bolted securely to your workbench.
For machine longevity:
• Make sure all moving parts are lubricated with machine oil or grease.
• Make sure the drive belt tension is tight enough to avoid slipping under
heavy load, but not so tight as to overload the motor and spindle bearings.
• Keep the machine clean.
Use common sense:
• Do not use the machine for other than its intended purpose.
• Do not use the machine to do jobs that it was not designed to do.
• Do not use the machine to do work in excess of its rated capacity.
Be careful!
Make sure you unplug the machine before changing chucks, collets, cutters
or any other tooling, or before performing any maintenance work.
After changing any tooling, rotate the spindle by hand to make sure everything
is mounted correctly and nothing can fly off the machine when it is powered up.
AND, MOST IMPORTANTLY, ALWAYS WEAR SAFETY GLASSES

The machine is packed in two separate cartons...one carton contains
the machine base with the table already installed; the other contains
the headstock/motor assembly.
Carefully remove the components (Watch out! They are heavy. Get
assistance if you cannot lift these items by yourself). Clean off all
extraneous oil and shipping debris. Locate the tools and hardware
packed in their own bag or box.
Place the base on your workbench. Install the column by bolting it in
place on the machine base as shown in the picture. Use large hex bolt
and key to secure.
Note: Black knob on rear of base may have to be pulled out to
position the column properly. Knob operates locking pin which
will hold the column at a perfect 90 degree angle to the base.
2
Install the handwheel handles by screwing them onto the
handwheels. Hold the knob while tightening the screw
with a screwdriver.
Assembly is now complete.
Make sure everything turns smoothly before using the machine.
Now, bolt the machine securely to your workbench. Due to the
wide variety of workbenches that will be used, we have left the
selection of suitable hardware up to the user. If you are not sure
how to bolt down the machine, seek the help of a knowledgeable
assistant.
Plug the machine into a grounded electrical wall outlet supplying
120vAC.
The electrical power/safety system is protected by a large red
switch located on the right side of the control box. To unlock the
safety shut-off switch, slide the big red cap toward the front of the
machine to undo the latch. Then swing open the door a bit. If the
speed control is all the way counterclockwise (in the clicked-off
position), the green panel light will light, indicating you are ready
to turn up the speed.
If the yellow fault light is also lit, then you must turn the speed
control to the clicked-off position to clear the fault. Note: this is a
safety feature that prevents the machine from starting by itself
(without manually controlling it with the speed control knob).
If the machine fails to start under any circumstances, unplug it from
the wall power and check the fuse located behind the access plug
located in the lower right corner of the control panel.
Leave the door in the position shown in the picture...near the big
red button as shown. It is now in the best position for readiness
in case of emergency.
In case of an emergency, simply slap the red cap with the palm of
your hand to cut power.

Turn on the machine by rotating the speed
control knob.
Note: The rule of thumb for speed control is
that small cutting bits require fast speeds,
and vice versa.
The handwheel dial may be reset to any
position by holding the outer knob while
rotating the inner dial to any reading...
perhaps to zero for establishing a new datum. To remove a drawbar-held shank, first loosen
the drawbar by about 3 turns. Then, tap the top
of the drawbar with a plastic-tipped hammer to
push out the taper. Then, while holding the
chuck, collet holder or other tooling, remove
the drawbar. Be careful...do not let the tooling
drop out of the spindle and dent the table or
vise! It's always a good idea to protect the
table or vise with a foam pad or heavy rag...
just in case.
Use the included key to tighten the chuck. Make
sure the shank of the bit is centered in the jaws
before turning on the motor. Use the key again
to loosen the chuck.
Remove the Phillips retaining screw on the left
edge of the belt cover, and then slide the belt
cover to the left and forward to remove it.
Slide the motor towards the spindle to loosen
the belt.
Move the belt to the alternate step. (Note: the
spindle will run slower with the belt on the
upper step). Be sure the belt will track properly.
Slide the motor away from the spindle to
tighten the belt and replace the belt cover and
retaining screw. Now hold the motor so that
the belt is tight, and tighten the four motor
mounting screws to lock everything in place.
The table and column motion has been
adjusted at the factory for maximum
smoothness with minimum “play.” Sometimes
a machine can develop a bit of play, in which
case you should adjust the “gibs” as follows:
loosen the lock nuts with an open-end wrench,
adjust the set screws to apply just a small
amount of pressure, and then retighten the lock
nuts. This requires the development of a certain
amount of “feel” to perform correctly. If you're
not sure about how to do this correctly, ask a
friend-in-the-know to help you. The center
screw is used to lock the table in position while
machining; it is not a gib adjusting screw.
The drive system uses a two-speed pulley to
provide two speed ranges...a low speed for
large cutters, and a high speed for small
cutters. To change the belt from one speed to
the other, follow this procedure:
Gently pry off the cap to uncover the place for
tightening the drawbar.
Note: Morse Tapers are designed to hold
chucks and other tooling without requiring
the use of a drawbar, but its use prevents
accidental loosening.
Place the shank of the chuck into the underside
of the spindle and insert the drawbar from the
top until it can be screwed into the end of the
shank. Tighten gently by hand to draw the
shank into the spindle. Use the included
spanner wrench as shown in the picture to
hold the spindle from turning while gently
tightening the drawbar bolt with an open end
wrench (use one or two washers under the
head of the screw. Just snug up the bolt a bit
(avoid overtightening); otherwise, it will be
very difficult to separate the Morse Taper
parts later. Make sure everything runs “true.”
Use a hex key to loosen the four motor
mounting bolts.
