Turn-Nado®Gearhead Lathes

Spindle Clutch

Adjustment

This lathe uses a dual-clutch mechanism to drive the spindle. The clutch assembly will need to be adjusted if you have difficulty engaging the forward or reverse spindle lever position or if the chuck takes more than 3–4 seconds to reach full speed when set at the highest spindle speed.

DISCONNECT LATHE FROM POWER before performing this procedure. Failure to do so could result in accidental startup, electrical shock, entanglement or crushing injury, or property damage.

DO NOT touch hot components. During use, the clutch and other internal components can become very hot. Wear heavy gloves or allow components to cool before service.

Wear safety glasses throughout the entire procedure. Oil may splash and spring-loaded components may be thrown, resulting in injury or loss of vision.

DO NOT rotate the spindle or input pulley by hand while hands or fingers are inside the headstock. Doing so may cause entanglement and serious crushing injuries.

Support components while their mounting fasteners are being removed. Components may fall or swing outward if they are not properly supported, resulting in crushing or laceration injuries.
