MAINTENANCE
Priming the Oil Pump
The lubrication system is also equipped with a
check valve that is shown in Figure 121. This
valve allows oil to flow to the headstock during
pump operation, but prevents the oil from
draining back into the tank and the pump from
losing its prime when not in operation. However,
if after long-term storage, or if the machine is
being started for the first time in test run, we
recommend that the pump and line be primed
with oil to prevent a dry run.

To prime the oil pump:
1. DISCONNECT LATHE FROM POWER!
2. Remove the end gear cover.
3. Remove the headstock oil supply line from
the check valve, as shown in Figure 121.
4. Fill the supply line with oil, reinstall, and
test pump operation and verify oil flow.

Checking & Adding Oil
The sight glass shown in Figure 122 shows the
oil level in the gearbox. At the full level, the oil
fills approximately
3
⁄4 of the sight glass. At the
add level, the oil fills
1
⁄4 of the sight glass or less.
Check the oil level daily.

Changing Oil
The gearbox oil must be changed after the
break-in period and then annually (or every six
months with hard service or extreme working
conditions). Figure 123 shows fill and drain
plugs used when changing the gearbox oil. The
fill plug is removed with a 20mm wrench, and
the drain plug is removed with a 16mm wrench.
