Loosen the clamp at the base of the tailstock casting. The tailstock base is
positioned manually, then secured in place using the two clamps. The hand
wheel on the rear of the casting is then used to drive the quill in and out. The
TL-1/2 tailstock has a #4 Morse taper (MT4), the TL-3's use an MT5 and the
TL-4 uses an MT6.
The TL-4 tailstock is moved by pinning it to the saddle and using the hand-
wheel on the pendant to jog the Z-axis and move the tailstock into the desired
position. To secure the TL-4 tailstock:
1. Tighten the pressure knob on the hydraulic system.
2. Use the hand pump on the hydraulic system to increase the pressure to
between 2000 and 2300 psi.
3. Use the tailstock handwheel to extend the quill and lock it into place with the
lever.
NOTE: Remember to remove pressure by loosening the hydraulic
pressure knob before moving the tailstock.
CAUTION: When hydraulic pressure drops to 1500 psi during operation,
the spindle will stop. Check hydraulic pressure often to ensure
it does not drop below 2000 psi.
When tailstock is not in use, jog it to the rear stops. Hydraulic pressure is not
needed to keep it in position.

If installed, the optional tool turret can be removed if extra space is required for
large parts or special tooling setups. The following instructions detail removal
and reinstallation for each of the tool turrets available.

Removal
1. Turn the air to the tool changer off (Either disconnect air to the regulator or
turn the regulator knob counterclockwise until pressure reads zero). Remove
the turret motor cover and disconnect the air line and electrical cables from
the turret. Unbolt the turret and lift off of the machine (Note shim locations for
reinstallation).
2. Remove the riser block from the cross slide (TL-2).
3. Cap the electrical cable and air line, then install the chip shield.
4. Change setting 113 to either "TL Post" or "Gang TL" as appropriate.
