SETUP
Before setting up your machine you must
read and understand the instructions given
in this manual.
The unpainted surfaces of this lathe are
coated with a rust preventive waxy oil
and you will want to remove this before
starting assembly. Use a solvent cleaner
that will not damage painted surfaces.
WARNING
WBL290F is a very heavy
machine, do not over-exert
yourself. Use fork truck or other
mechanical devices for safe
moving method
When setting up your machine, you will
want to find an ideal spot where your
metal lathe will most likely be positioned
most of the time.

any part, check if the part is already installed
on the machine. Some of the parts come
assembled with the machine because of
shipping purposes.

PROPER GROUNDING
Grounding provides a path of least
resistance for electric current to reduce
the risk of electric shock.
WBL290F is equipped with a 110-V single
phase motor.
To prevent electrical hazards, have a
qualified electrician ensure that the
line is properly wired.
This lathe is for use on a norm al 110 volt
circuit. Make sure that the appliance is
connected to an outlet having the same
configuration as the plug. If an adaptor
plug is used, it must be attached to
themetal screw of the receptacle.
Figure-3 110-Volts Outlet for WBL290F
WARNING
Improper connection of the equipment-
grounding conductor can result in a risk
of electric shock. Check with a qualified
electrician if you are in doubt as to
whether the outlet is properly grounded.
It is strongly recommended not to use
extension cords with your WBL290F
Always try to position your machine
close to the power source so that
you do not need to use extension
cords. When it is necessary to use
an extension cord, make sure the
extension cord does not exceed
50-feet in length and the cord is
12-gauge to prevent motor damage. Y
our WBL290F should be wired with a
plug having 3-prongs to fit a 3 prong
grounded receptacle as shown in
figure-3. Do not remove the grounding
prong to fit it into a 2-pronged outlet.
Always check with a qualified
electrician if you are in doubt.

CHUCK
WBL290F comes equipped with a 160mm,
3-jaw chuck, and a 270mm face plate.
The 3-jaw chuck is a scroll type chuck,
meaning that all three jaws move in
union when adjusted while the 4-jaw
chuck features four independent jaws.
The 4-jaw chuck is used to clamp
square or unevenly shaped work-pieces.
Figure-4 Chuck mounting screws and nuts
When removing the chuck,loosen the hex
nuts,tum the washer counter-clockwise and
pull out the chuck. See figure-4.
STEADY REST
The steady rest supports long, small
diameter stock that otherwise could not be
turned. The steady rest can also replace the
tailstock to allow for cutting tool acces at the
outboard end of your work-piece. To mount
the steady rest:
Secure the steady rest to the lathe bed from
below with a locking plate.
A single cap screw, along with a nut and
washer hold the steady rest in place as
shown in figure-5.
Figure-5 Steady rest
TO SET-UP THE STEADY REST:
Make sure the switch is in the OFF
position and the cord is disconnected
from the power source.
Loosen the hex nuts shown in figure-5.
Loosen knurled screw and open the sliding
fingers until the steady rest can be moved
with its finger around the work-piece.
Secure the steady rest in position.
See figure-5.
Tighten the knurled screw so that the
fingers are snug but not tight against
the work-piece. Tighten three hex
nuts shown in figure-5 and lubricate
the sliding points with machine oil.

10
The sliding fingers of the steady rest shown
in figure-5 should receive periodic lubrication
when used, to prevent premature wear.
FOLLOW REST
The follow rest is mounted on the saddle with
two cap screws shown in figure-6 and it follows
the movement of the tuming tool.Only two
sliding fingers are required. The place of the
third finger is taken by turning tool. The follow
rest is used for turning operations on long
slender work-pieces. It prevents flexing of
the work-piece under pressure from the turning
tool.
Set the fingers snug to the work-piece
and make sure not to over tighten. Lubricate
the fingers during operation to prevent
premature wear,

LATHE BED
The lathe bed is made of high quality iron
and features high cheeks with strong cross
ribs ensuring low vibration and rigidity.
It integrates the headstock and drive unit,
for attaching the carriage and leads crews. The
two precision ground V-side ways
are re- enforced by heat hardening
and grinding to guide the carriage and
the tailstock accurately. The main
motor is mounted to the rear of the
left side of the bed.
Figure-7 Lathe bed
HEADSTOCK
Made from high quality, cast iron for low
vibration, the headstock is bolted to the
bed with four screws. The headstock
houses the main spindle with two
precision taper roller bearings and
the drive unit.
The main spindle transmits the torque
during the turning process and it also
holds the work-piece and clamping devices.
