Setting Up The Lathe; Electrical Requirements; Lifting The Lathe - OTMT SC4 User Manual And Installation Manual

Setting up the Lathe

The SC4 lathe should be located in a well-
lighted and well-ventilated area free from
excessive humidity or moisture that could
cause rusting of the precision metal surfaces
or tooling.

Electrical Requirements

The SC4 lathe configured for U.S. operation
uses standard 120V AC 60-cycle single-phase
power and has a peak current demand of 12
amps. While a 15-amp circuit may be sufficient
for powering the lathe, a 20-amp circuit is
recommended. The circuit must not be shared
with other high-current devices, such as an air
compressor, window air conditioner or coffee
pot, that may be operating, or switch on, while
the lathe is in use. Low current devices, such
as a work lamp, may share the same circuit as
the lathe.
A plug-in power failure emergency light that will
automatically turn on in the event of a power
failure or tripping of an overloaded circuit
breaker is recommended for safety. In the
event that power to the lathe, or workspace
lighting, should be interrupted while the lathe is
in use, the emergency light will enable the
operator to safely turn off the power switch to
the lathe and move away from the lathe until
power is restored. Suitable lights are available
at most hardware and home-supply stores.
Care should be taken to ensure a safe work
area with electrical wiring and grounding
approved by local electrical codes. The lathe
uses a three-prong electrical plug to protect the
operator from risk of shock or electrocution.
The lathe must be plugged into a properly
grounded outlet to ensure safe operation. Do
not attempt to modify the plug to fit a 2-prong
outlet or extension cord by removing the
ground conductor or by using an adaptor.
Doing so may result in shock or electrocution.
If it is necessary to plug the lathe into an
extension cord, the extension cord must have

a properly functioning 3-prong electrical ground
plug and outlet, plugged into a properly
grounded 3-prong wall outlet. The extension
cord must have at least 15 Amps of current-
carrying capacity to avoid overheating the cord,
which could cause a risk of fire. A cord rated
for 20 Amps or more is recommended. In no
case should the length of the extension cord
exceed 20 feet.

Lifting the Lathe

The SC4 lathe weighs approximately 275 lbs.
(125 kg.) and must be mounted on a strong
table or bench capable of supporting 350 lbs.
or more. A shop crane with a nylon lifting strap
or other suitable lifting apparatus should be
used to safely lift the machine onto the table or
bench.

Proper lifting techniques (e.g. bend at the
knees, not at the back) should be used to
minimize any risk of personal injury. Consult
the Internet for information on proper lifting
techniques.
