Headstock

The headstock is supplied with oil from the oil tank in the base of the left stand.

When the spindle motor is started, a belt-driven oil pump circulates oil across the headstock gears before spindle rotation is started.

Remove the end gear cover and the side access panel from the left stand, then unthread the oil fill cap to check the oil level on the dip stick (see Figure 29).

If the oil on the dip stick is less than 3" from the tip of the stick, add oil.

Changing Headstock Oil

The headstock oil must be changed after the break-in period and then annually (or every six months with heavy service or extreme working conditions).

Since this lathe uses a base-mounted oil tank, removing the drain plug and using a drain pan is not a convenient option when changing the oil. Alternately, we recommend using a remote oil pump with a suction hose that can be inserted through the filler spout to the bottom of the oil tank.

If a remote oil pump system is not available, use the headstock oil pump for this purpose, as instructed below.
