OPERATING LEVERS
Metal Lathe Operating Levers (Fig.2)
Headstock Levers
•Lever 1 is the H/L speed selector, this lever allows you to set the
speed to H (high) or L (low).
•Lever 2 is the 4-step speed selector which allows you to set the
spindle speed.
•Lever 3 is the spindle direction selector. Do not change this setting
while the machine is running.
Quick Change Gear Box Knobs
•Selector knobs 4, 5, 6 & 7 set the gear box feed rate. Turning these
knobs can provide many feed rates and inch thread pitches as
indicated in the charts in the metal lathe plates. With the use of
metric change gears, these levers can also provide metric threads
using the “MM Gear Change” chart which is also found in the metal
lathe plates.
Caution: Always stop the spindle before engaging any of the
above knobs (knobs 4-7).
Carriage Assembly Levers
• Handwheel 8 is used to manually move the carriage along the
bedway of the lathe.
• The crossfeed handwheel 10 is used to manually move the cross
slide in or out.
• The feed lever 11 is used to engage either the longitudinal or cross
feed. This lever has a safety interlock to prevent accidental
engagement of the half nuts when the lathe is in feed mode. There
are 3 positions; the upper position engages the power longitudinal
feed, the lower position engages the power cross feed and the
center position is the disengaged position.
• The thread lever 12 is used to engage the half nuts when threading.
• The top slide handwheel 17 is used to manually move the tool post.
The top slide is fully adjustable to any angle and is also used for
threading or machining an angle on a workpiece.
• The thread cutting dial 16 is used to engage the half nuts with the
leadscrew in the same thread that has been previously cut. Please
note: Use any line of the dial for even pitches of threads, but for odd
pitches of threads you must use the same starting line. Example:
When cutting a shaft with 10 T.P.I., engage the half nuts at any
number on the thread dial, when creating an odd pitch, if you start
the cut using 1 or a 3, continue to use the 1 or the 3 until the thread
is finished.
• The clamp lever 18 is used to secure the tool post block.
Tailstock levers
• The handwheel 13 is used to feed or retreat the tailstock quill. Tip:
Turning the handwheel completely couterclockwise until a full stop
will automatically eject the tourning tool used.
• The tailstock clamp lever 14 locks the tailstock to the bedway. To
lock, pull the lever upwards, to release lower the lever.
Stand
• Foot brake 9 stops the spindle. This allows you to stop the spindle
quickly and then change the rotation if needed.
