4. Cover all chuck jaws and scroll inside the
chuck with Mobilith® AW2. Cover the spindle,
cam locks, and chuck body with a light film of
Mobil DTE® Oil Heavy Medium.
5. Lift the chuck up to the spindle nose and press
onto the spindle. Tighten in place by turning
the cam locks 1/4 turn clockwise. The index
mark (A, Fig. 3) on the camlock should be
between the two indicator arrows (B, Fig. 3). If
the index mark is not between the two arrows,
remove the chuck and adjust the camlock
studs by either turning out one full turn (if
cams will not engage) or turning in one full turn
(if cams turn beyond indicator marks).
6. Install chuck and tighten in place.
7.0 Lubrication
Lathe must be serviced at all
lubrication points and all reservoirs filled to
operating level before the lathe is put into
service. Failure to comply may cause serious
damage to the lathe.

in oil sight glass (A, Fig. 4). Top off with Mobil
DTE® Oil Heavy Medium. Fill by pulling plug

completely and refill after the first month of
operation. Clean out any metal shavings.
Then, change oil in the headstock annually.
2. Gearbox – Oil must be up to indicator mark in
oil sight glass (B, Fig. 4). Top off with Mobil
DTE® Oil Heavy Medium. Fill by lifting off
thread chart cover (E, Fig. 4) and remove plug

remove drain plug (A, Fig. 6) with an 8mm hex
wrench. Drain oil completely and refill after the
