9.0 Electrical connections
Electrical connections must be
made by a qualified electrician in compliance
with all relevant codes. This machine must be
properly grounded to help prevent electrical
shock and possible fatal injury.
The GH-1440-1 lathe is rated at 3HP, single-
phase, 230V only. The GH-1440-3 lathe is rated
at 3HP, 3-phase, 230V/460V (prewired 230V).
Confirm power available at the lathe's location is
the same rating as the lathe.
Lathe Power Source Junction Box: Remove the
cover. Run the main power through the strain relief
bushing and attach the ground, followed by power
leads. Replace the cover.
Main Power Switch: Located on the backside of
the machine. Turns the power to the machine on
and off.
Make sure the lathe is properly grounded.
Power is connected properly when pulling up on
the forward-reverse lever causes spindle to rotate
counterclockwise as viewed from tailstock. If the
chuck rotates in clockwise direction, disconnect
lathe from power source, switch two of three power
leads, and re-connect lathe to power source.
9.1 Voltage conversion (GH-1440-3
only)
Disconnect machine from
power source. Failure to comply may cause
serious injury!
