WARNING

Read and understand all directions for chuck preparation!
Failure to comply may cause serious injury and/or damage
to the lathe!

CAUTION

Lathe must be serviced at all lubrication points and all re-
servoirs filled to operating level before the lathe is put into
service! Failure to comply may cause serious damage to the
lathe.

Uncrating and Clean-Up

1. Finish removing the wooden crate from around the lathe.
2. Unbolt the lathe from the shipping crate bottom.
3. Choose a location for the lathe that is dry, has good lighting, and has

enough room to be able to service the lathe on all four sides.

4. Sling lathe after placing steel rods or pipes (of sufficient strength) into

holes of lathe stand as diagrammed in Fig. 2. Do not lift by spindle.
With adequate lifting equipment, slowly raise the lathe off the shipping
crate bottom. Make sure lathe is balanced before moving.

5. To avoid twisting the bed, the lathe's location must be absolutely flat

and level. Check for a level condition using a machinist's precision le-
vel on the bedways both front to back and side to side. The leveling
pads included in the toolbox and the leveling screws in the lathe base
will help you to reach a level condition. The lathe must be level to be
accurate.

6. Clean all rust protected surfaces using a mild commercial solvent, kero-

sene or diesel fuel. Do not use paint thinner, gasoline, or lacquer thin-
ner. These will damage painted surfaces. Cover all cleaned surfaces
with a light film of 20W machine oil.

7. Remove the end gear cover. Clean all components of the end gear as-

sembly and coat all gears with a heavy, non-slinging grease. Replace
cover.

Chuck Preparation (Three Jaw)

Note:

Before removing the chuck from the spindle, place a way board

across the bedways under the chuck.
1. Support the chuck while turning six camlocks 1/4 turn counter-clock-

wise with the cam lock key enclosed in the toolbox.

2. Carefully remove the chuck from the spindle and place on an adequate

work surface.

3. Inspect the camlock studs. Make sure they have not become cracked or

broken during transit. Clean all parts thoroughly with solvent. Also
clean the spindle and camlocks.

4. Cover all chuck jaws and scroll inside the chuck with #2 lithium tube

grease. Cover the spindle, cam locks, and chuck body with a light film
of Mobil DTE® Oil Heavy Medium oil.

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 in-
dex mark (A, Fig. 3) on the camlock should be between the two indic-
tor arrows when tight (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.

Lubrication

1. Headstock -

Oil must be up to indicator mark in oil sight glass (A,

Fig. 4). Top off with Mobil DTE® Oil Heavy Medium. Fill by remo-
ving the plug on the top of theheadstock. To drain, remove drain plug
on the left side of the headstock at the lower rear corner. Drain oil
completely and clean out all metal shavings. Refill after the first month
of operation. Then change oil in the headstock every two months.

2. Gearbox -

Oil must be up to indicator mark in oil sight glass (B, Fig.

4). Top off with Mobil DTE® Oil Heavy Medium. To add oil to the
gearbox, remove two screws on the top cover. To drain, remove drain
plug (C, Fig.4) on the left side of the gearbox. Drain oil completely
and refill after the first three months of operation. Then change oil in
the gearbox every six months.
