Sherline 5000 Mill Assembly Instructions

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.
FIGURE 1—Proper grounding for electrical
connections.
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, we used an AC/DC motor. 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 first 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 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.

1. KNOW YOUR POWER TOOL—Read the owner’s manual
carefully. Learn its application and limitations as well as
the specific 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 in right-hand column.)
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 KID-PROOF—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 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 and
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 ON THE
MOTOR—This ensures that the workpiece or chuck jaws
will not hit the lathe bed, saddle or crosslide, and also
ensures that they clear the cutting tool.
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
effectiveness.
20. DON’T USE YOUR LATHE FOR GRINDING—The fine dust
that results from the grinding operation is extremely hard
on bearings and other moving parts of your tool. For the
