Maintenance and
Service
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 25 – 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.

The variable feed gearbox and the disc brake feed
mechanism assemblies do not require lubricant.
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.

Oil exposed metal parts periodically to prevent rust.
Cleaning
Keep the lathe as clean as possible for trouble-free
operation, as well as safety and longer lathe life. Use a
brush to sweep metal chips and dust off the lathe.
Do not use compressed air to blow the lathe clean.
Chips and dust may be driven between machined parts
and into bearings, causing undue wear.
Care of Arbors and Adapters
Although the adapters, arbors, and spindle are made
of top grade steel and are turned, hardened, and preci-
sion ground to close tolerances, great care should be
taken in their use, handling, and storage. Even the
smallest nick, scratch, or loose chip can cause incorrect
rotor or drum alignment, resulting in inaccurate recon-
ditioning.
Remove all adapters from the arbor after recondition-
ing a drum or rotor and wipe them clean – especially
the inboard adapter. When a finished drum or rotor is
removed from the arbor, the inboard adapter may move
slightly away from the face of the arbor and allow metal
chips to fall into the opening, causing a poor mounting
for the next drum or rotor.
Regularly inspect the faces and seating tapers of the
adapters for nicks and scratches, correct any flaw with
a fine stone. If the damage cannot be corrected,
replace the adapter. Handle the adapters and arbors
with care and store them on individual hooks. Do not
throw them into a box. The adapters are designed for
mounting drums and rotors only. Do not misuse the
adapters.
