Unpacking

Open shipping cont ainer and check f or shipping
damage. Report any damage immediately to
your distributor and shipping agent. Do not
discard any shipping material until the Lathe is
assembled and running properly.

Compare the cont ent s of y our cont ainer wit h the
following parts list to make sure all parts are
intact. Mi ssing parts, if any, should be reported
to your distributor. Read the instruction manual
thoroughly for assembly, maintenance and
safety instructions.

Uncrating and Cleanup

1. Finish removing the wooden crate from
around the lathe.

2. Unbolt the lathe from the shipping crate
bottom.

3. Choose a location f or the lathe that is dry,
has good light ing, and has enough room t o
allow servicing the lathe on all four sides.

4. Sling t he lathe as shown i n Figure 1, using
steel rods or pipes of sufficient strength
inserted through the holes in the bed
casting. Do not lift lathe by the spindle.
With adequate lifting equipment, slowly
raise the lat he off the shipping cr ate bot tom .
Make sure lathe is balanc ed 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 level on the bedways
both front to back and side to side. The
leveling pads included in the tool box and
the leveling screws in the lathe base will
help you to reach a level condition. The
lathe must be level to be accurate.

Figure 1

6. Clean all rust protected surfaces using a
mild commer cial solvent , kerosene or di esel
fuel. Do not use paint thinner, gasoline, or
lacquer thi nner. These will damage painted
surfaces. Cov er all cleaned surf aces with a
light film of 2 0W m achine oil .

7. Open the end gear cover. Clean all
components of the end gear assembly and
coat all gears with a heavy, non-slinging
grease. Close the end gear cover.

Chuck Preparation (Three Jaw)

Read and understand all

directions for chuck preparation. Failure to
comply may cause serious injury and/or
damage to the lath e.

NOTE: Before removing the chuck from the
spindle, place a flat piece of wood (plywood,
etc.) across the bedways under the chuck to
prevent damage to the bedways should the
chuck fall from your hands.

To remove the chuck:

1. Support the chuck while turning six
camlocks 1/4 t urn countercl ockwise with the
chuck wrench fr om the tool box.

2. Carefully remove t he chuck from the spindl e
and place on an adequate work surface.

Figure 2

11

3. Inspect the cam lock studs. Make sure they
have not become crac ked 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 li thium tube grease. Cov er the
spindle, camlocks, and chuck body with a
light film of 2 0W oil.

5. Lift the chuck up to the spindle nose and
press onto the spindle. Tighten in place by
turning the c amlocks 1/4 turn cloc k wise. The
index mark (A, Figure 3) on the camlock
should be between the t wo indicator ar rows
when tight (B , Fi gure 3). If the i ndex mark i s
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 indic ator marks.)

6. Install chuck and tighten in place.

Lubrication

Figure 3

L athe must b e serviced at all

lubrication points and all reservoi rs filled to
operating level before the lathe is put into
service. Failu re to comply may cause serious
damage to the lath e.

1. Headstock – Oil must be up to indicator
mark in oil sight gl ass (A, Figure 4). Top off
with Mobil DTE® Oil Heav y Medium. Fill by
removing the pl ug on top of the headstock.
To drain, r emove drain pl ug on the left si de

The main motor is rated at 7-1/2 HP (or 10HP
for model 2280ZX), 230/460V and comes from
the factory prewir ed at 230V. Confirm that power
available at the lathe’s location is the same
rating as the lat he.

Power is connected properly when rotating the
forward-reverse knob (E, Figure 12) to the left
position causes the spindle to rotate
countercloc kwise as v i ewed from the t ail stock. If
the chuck rotates in the clockwise direction,
disconnect the lathe from the power source,
switch any two of the thr ee power lead s (not t he
green ground wire), and re-connect the lathe to
the power source.

General Description

Lathe Bed

The lathe bed (A , Figure 10) is made of c ast iron
with low vibration and high rigidity. Two
precision ground v-slideways, reinforced by
induction hardening and grinding, are an
accurate guide for the carriage and headstock.
The main drive motor is mounted in the stand
below the the headstock.

Figure 10

Headstock

The headstock (B, Figure 10) i s cast from high
grade, low vibr ation cast iron. It is bolted to t he
bed by four hex socket cap bolts. In the head,
the spindle i s mounted on precision t aper roller
bearings.

14

Carriage

The carriage (C, Figure 10) is made from high
quality cast ir on. The cross-sli de (E, Figure 10)
is mounted on the carriage and moves on a
dovetail ed slide which can be adj usted for pl ay
by means of the gibs.

The compound sli de (D, Figure 10) which is T­slotted, and mounted on the cross slide (E,
Figure 10) c an be rotated 360°. The compound
slide and the cross slide travel in a dovetailed
slide and have adj ustable gibs.

Four Way Tool Post

The four way t ool post (F, Figure 10) is mounted
on the compound slide and allows a maximum
of four tools to be mounted at the same time.
Remember to use a minimum of two clamping
screws when installing a cutting tool.

Apron

The apron (G, Figure 10) is mounted to the
carriage. Quick travel of the apron is
accomplished by m eans of a bed-mount ed rack
and pinion, operated by the handwheel on the
front of the apron.

Tailstock

The tailstock (H, Figure 11) slides on a v-way
and can be locked at any l ocati on by a clamping
lever. T he tail stock has a heavy duty qui ll wit h a
Morse Taper #4, or Morse Taper #5 (18” and
22” models).

Leadscrew and Feed Rod

The leadscrew (J, Figure 11) and feed rod (K,
Figure 11) are mounted on the front of the
machine bed. They are connected to the
gearbox at the left and are supported by
bearings on both ends. Both ar e equipped with
shear pins.

Feed Gearbox

The gearbox (L, Figure 11) is made from high
quality cast i ron and is mounted to t he left side
of the machine bed.

Figure 11

Steady Rest

The steady rest (M, Figure 11) serves as a
support for shaf ts on the free tailstoc k end. The
steady rest is mounted on the bedway and
secured fr om below with a bol t, nut and loc king
plate. The sliding fingers require continuous
lubrication at the contact points with the
workpiece to prevent them from premature
wear.

15

To set the steady rest:

1. Loosen three hex socket cap screws.

2. Loosen knurled screw and open sliding
fingers until the steady rest can be moved
with its fingers around the workpiece.
Secure the steady rest in position.

3. Set the fingers snugly t o the workpiece and
secure by tightening three hex socket cap
screws. Fingers should be snug but not
overly tight. Lubricate sliding points with
lead-based grease.

Follow Rest

The traveling follow rest (N, Figure 11) is
mounted on the saddle and follows the
movement of the turning tool. Only two fingers
are required a s the pl ace of t he thi rd i s taken by
the turning tool. The follow rest is used for
turning operat ions on long, slender workpieces.
It prev ents the workpiece f rom fl exing under the
pressure of t he cutting tool.

The slidi ng fingers are set simi lar to the steady
rest, free of play, but not binding. Always
lubricate adequately with lead-based grease
before operating.
