OPERATION
A. SIMPLE TURNING
Before starting the machine as described above, it is impe-
rative that the setup for the type of work to be carried out is
fully checked
.
The following notes are guidelines as to how to set up the
lathe to carry out a simple turning operation.
ALWAYS plan your work. Have drawings or a plan on hand,
together with any measuring instruments you may require,
such as micrometes, calipers etc.

Taking all precautions previously stated, set the High-Low
range lever (item 26) to
Low
. Must close the chuck guard
for 3-jaw chuck.
Be sure the cross-slide is well away from the chuck. And the
automatic feed lever is in its disengaged position, (i.e. lever
is UP). Insert the electric plug into the wall socket.
Select
FORWARD
, using the Forward / Off / Reverse
(F/O/R) Switch (B) on the main control panel, then release
the Emergency Stop Switch by pushing down on the red
knob slightly and pushing it in towards the headstock, as
indicated by the arrow on the top of the red knob (C). The
green lamp will light.
Switch on the machine by SLOWLY turning the variable
speed control knob (A) clockwise. Speed will increase pro-
gressively the further the knob is turned. You can then see
the spindle speed on the digital readout.
CAUTION: Always turn the speed control to the minimum
speed position before starting the lathe with the speed con-
trol set to a higher speed can damage the speed control cir-
cuit board.
Run for a total of 5 minutes during which time gradually
increase spindel speed to its Maximum. Run for at least 2
minutes at this speed before stopping the machine and
Disconnecting from the main supply.
Check that all components are still secure and working free-
ly and correctly.
Check also to ensure the mountings are secure.
Repeat the procedure at the
HIGH
range setting.
Should any adjustments be necessary, refer to the appropri-
ate section under “Settings and Adjustments”.
CAUTION:
NEVER attempt to change from HIGH to LOW
range with the machine running.
B. STARTING UNDER NORMAL CONDITIONS
(ref. fig 5).
1. Take all necessary precautions previously stated, and
ensure the work piece can rotate fully without obstruc-
tion.
2. Always have the speed range set to its lowest possible
RPM before switching machine on.
STARTING PROCEDURE
A. DURING INSTALLATION – INITIAL START
(ref. fig. 5)
3. Set the Forward / Off /Reverse (F/O/R) switch (B) on the
main control panel, to the FORWARD position.
4. Engage or ensure the Auto Feed lever in disengaged,
depending upon whether or not automatic feed is
required.
IMPORTANT: This should ALWAYS be a deliberate,
conscious action.
NOTE: If Auto feed is required, the Lead screw Forward /
Neutral / Reverse Lever should be set to FORWARD. If
Auto feed is not required the lever may be set to Neutral. To
do this, grasp the knurled handle and pull out against spring
pressure. Holding the handle in this position, move the lever
until the point end is located in the middle pit mark in the
casing.
5. Proceed to start the machine as described previously.
6. If you are done working, or if the machine is to be left
unattended, turn the F/O/R switch to the OFF position
then disconnect from the wall outlet.
ATTENTION:
The power supply system has an automatic
overload protective device. If the machine is overloaded, the
motor will automatically shut down, and a yellow lamp (D)
will light. To restart, turn the Forward / Off / Reverse switch
(B) to OFF clear any trouble from the machine before
attempting restart, check machine speed rang and set to
minimum speed. When ready to operate again place direc-
tional switch indesired position. (Green light should be on
and yellow of) adjust speed as required.
CAUTION:
ALWAYS turn the machine OFF at the Forward /
off / Reverse switch BEFORE ATTERMPTING TO
CHANGE ANY SETTINGS OR MAKE ANY
ADJUSTMENTS, INCLUDES CHANGING
FROM HIGH TO LOW RANGE.
