Maintenance and Service
Before making any inspection, adjustment,
or repair, make sure lathe is turned OFF and
disconnect the power source.
Wear protective clothing, equipment and
eye protection when making any adjust-
ments or repairs to the machine.
Oiling
The lathe is shipped from the factory with the correct
amount and type of oil. Check oil level frequently, and
refill as necessary with EP-80-90 gear oil.
Figure 34 – Oiling
After every 500 hours of use, drain the oil and refill to
the appropriate level on the dipstick with clean EP-80-
90 gear oil. Use the oil drain plug on the front of the
lathe to drain the old oil.
Figure 35 – Drain plug location
The Infimatic ® Variable Feed Gearbox and the disc
brake feed mechanism assemblies are filled with a spe-
cial lubricant and need no further internal lubrication.
Lubricate the cross feed once each month with an
automotive chassis grease. Pump the grease into the
fitting until clean grease comes out the relief slot at the
base of the fitting.
Use a hand pump grease gun only. A high pressure
gun can burst the lathe casting.

Grease the lead screw drive monthly. Locate the lead screw
drive by pulling the protective boot back.
