SPEED AND POWER CONTROLS
You can turn lathe on and off and control speed and direction from the main control panel.
The Power Switch
Turn the Emergency Stop Switch (C) clockwise; the Indicator
Light (D) will light up. The Spindle will not turn without operating
the Control Lever (V).
The Press Switch (A) is used to run the spindle temporarily to
allow the gears to engage when changing speed gears. When
you release the switch, the spindle will stop.
In an emergency, you can stop the machine by pressing the
Emergency Stop Control (C).
Speed and Direction Controls
Note: Do not change the settings of these controls if the motor is running.
Shut OFF the power before changing these settings.
The Spindle Speed can be controlled by setting the Speed Control knobs (G) and (H).
Refer to the chart on the Headstock to the right of the knobs to determine the proper
setting for the desired spindle rotation speed. Eighteen speeds are possible from 72 to
1600 RPM. The direction may be controlled using Direction Control (F).
Quick Change Gearbox
The headstock is equipped with a quick change gearbox to control the rate of the spindle to
the lead screw and feed rod, when it is used to cut threads, or for turning or facing.
Controls (CC) and (EE) may be used
in combination to control the feed rate.
Please refer to the lead screw chart (HH)
for the desired setting.
The change gears may need to be re-
placed to achieve the correct setting.
Be sure the machine is turned off and is
unplugged from its power supply before
replacing the gears. Select the gears
required from the lead screw chart.
When the Exchange Lever (BB) is in the
middle position, the Lead Screw (118)
and Feeding Rod (107) are locked. When
Exchange Lever (BB) is to the right, the
Lead Screw (118) is running and the
machine can be used to turn the threads.
When Exchange Lever (BB) is to the
left, the Feeding Rod is running and the
machine can be used set for automatic feeding.
The half nut is engaged or disengaged using the Half Nut Lever (X). Note that the half
nut must be engaged for the lead screw to function properly.
