Main Spindle Rotation
The spindle rotation direction can be selected by the spindle start lever on the side of the
apron.
Main Spindle Speed
The speed of the main spindle is selected by using the (High/Low) speed selector and the 4
step speed selector. This gives a total of 8 speed steps available on this machine. For the
correct speed, please refer to the speed chart.
Never attempt to change the spindle speed until the machine has come to a complete stop!
By rotating the chuck by hand, the spindle speeds can be more easily changed.
Running In
Running in of the machine should be carried out at the lowest possible speed, allow the
machine to run at this speed for approximately 20 minutes. Check for any abnormal noises
and if there are any noises stop the machine and investigate. If everything is normal,
gradually increase the spindle speed.
Operation
Only ever use high peripheral speed rated chucks with this machine.
The maximum spindle speed for a chuck exceeding 254mm should not exceed 1255rpm.
When the thread cutting or auto-feed functions are not in use, the feed/thread selector
should be in the neutral position so that the leadscrew and the feed rods are disengaged.
To avoid any unnecessary wear, the thread dial indicator should be out of mesh with the
leadscrew.
Spindle Nose Camlock System
When mounting the chuck, faceplate or any other attachment, ensure that the location faces
on both the spindle and the attachment are fully cleaned, in addition, all of the cams should
be in the disengaged position.
Mount the chuck onto the spindle nose and lock each cam by turning it clockwise using the
provided key. Mark the position on the chuck with a reference line for subsequent
mountings.
