on bearings and other moving parts of your tool. For
the same reason, if the lathe or any other precision
tool is kept near an operating grinder, it should be
kept covered when not in use.
21. Don't Let Long, Thin Stock Protrude from the Back of the
Spindle—
Long, thin stock that is unsupported and turned
at high RPM can suddenly bend and whip around.
22. Wear Your Safety Glasses—Foresight is better than NO
SIGHT! The operation of any power tool can result
in foreign objects being thrown into the eyes, which
can result in severe eye damage. Always wear safety
glasses or eye shields before commencing power tool
operation. We recommend a Wide Vision Safety Mask
for use over spectacles or standard safety glasses.
NOTE: Power cords are
available with UK and
European plugs.

Electrical Connections
The power cord supplied is equipped with a 3-prong
grounding plug that should be connected only to a
properly grounded receptacle for your safety. Should an
electrical failure occur in the motor, the grounded plug
and receptacle will protect the user from electrical shock.
If a properly grounded receptacle is not available, use a
grounding adapter to adapt the 3-prong plug to a properly
grounded receptacle by attaching the grounding lead from
the adapter to the receptacle cover screw.
NOTE: The electrical circuit designed into the speed
control of your lathe or mill reads incoming current from
100 to 240 volts AC and 50 or 60 Hz and automatically
adapts to supply the correct 90 volts DC to the motor. As
long as you have a properly wired, grounded connector
cord for your source, the machine will operate anywhere
in the world without a transformer. This has been true
for all Sherline machines built since 1994. Prior to that,
an AC/DC motor was used. Use that motor ONLY with
the power source for which it was intended. It will not
automatically adapt to any other current and using it with
an improper power source will burn out the motor or speed
control. Also, the rst few DC units built did not include
the circuits to adapt to other currents. If you think you
may have an early DC model, remove the plastic speed
control housing and look for a label on the aluminum
speed control frame. If it has a small metallic label on top
of the frame that lists input voltage as 120VAC, DO NOT
ATTEMPT TO CONVERT THIS MODEL TO OTHER
CURRENTS. Models that can be used with any current
have a paper label on the end of the speed control frame
which lists the model number as KBLC-240DS.

CE compliant electronic lter if required in your country.
1. Know Your Power Tool—Read the owner’s manual
carefully. Learn its application and limitations as well
as the specic potential hazards peculiar to this tool.
2. Ground All Tools—If a tool is equipped with a three-prong
plug, it should be plugged into a three-hole receptacle.
If an adapter is used to accommodate a two-prong
receptacle, the adapter wire must be attached to a
KNOWN GROUND. Never remove the third prong.
(See Figure 1.)
3. Keep Guards in Place—and in working order.
4. Remove Adjusting Keys and Wrenches—Form a habit of
checking to see that keys and adjusting wrenches are
removed from the tool before turning on any machine.
5. Keep Work Area Clean—Cluttered areas and benches
invite accidents.
6. Avoid a Dangerous Work Environment—Do not use power
tools in damp or wet locations. Keep your work area
well illuminated.
7. Keep Children Away—All visitors should be kept a safe
distance from the work area.
8. Make Your Workshop Childproof—with padlocks, master
switches or by removing starter keys.
9. Do Not Force a Tool—Do not force a tool or attachment
to do a job for which it was not designed. Use the
proper tool or accessory for the job.
10. Wear Proper Apparel—Avoid loose clothing, neckties,
gloves or jewelry that could become caught in moving
parts. Wear protective headgear to keep long hair styles
away from moving parts.
11. Use Safety Glasses—Also use a face or dust mask if a
cutting operation is dusty.
12. Secure Your Work—Use clamps or a vise to hold work
when practicable. It is safer than using your hand and
frees both hands to operate the tool.
13. Do Not Overreach—Keep your proper footing and
balance at all times.
14. Maintain Tools in Top Condition—Keep tools sharp
and clean for best and safest performance. Follow
instructions for lubrication and changing accessories.
15. Disconnect Tools— Unplug tools before servicing, or when
changing accessories such as blades, bits or cutters.
16. Avoid Accidental Starting—Make sure the switch is “OFF”
before plugging in a power cord.
17. Use Recommended Accessories— Consult the owner's
manual. Use of improper accessories may be hazardous.
18. Turn the Spindle by Hand Before Switching Motor On—This
ensures that the workpiece or chuck jaws will not hit
the lathe bed, saddle, crosslide or cutting tool and that
a key or spindle bar was not left in the chuck.
19. Check that all Holding, Locking and Driving Devices Are
Tightened—At the same time, be careful not to
overtighten these adjustments. They should be just
tight enough to do the job. Overtightening may damage
threads or warp parts, thereby reducing accuracy and
eectiveness.
20. Don't Use Your Lathe for Grinding—The ne dust that
results from the grinding operation is extremely hard
