Sherline Lathe User Guide and Specifications
20. It is not recommended that the lathe be used 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 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.
Electrical connections
The power cord used is equipped with a 3-prong grounding plug which should only be
connected 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.
FIGURE 1-Always use a properly grounded receptacle.
NOTE: The electrical circuits 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
