Switch on the machine by GENTLY turning the Variable Speed control knob(4), clockwise. A

click will be heard as power is turned on, but the spindle will not rotate until the knob is turned

clockwise a little further. Speed will increase progressively the further the knob is turned.

Run of a total 5 minutes during which time gradually increase spindle speed to its maximum. Run

for at least 2 minutes at this speed before stopping the machine and disconnecting from the

mains supply.

Check that all components are still secure and working freely and correctly.

Check also to ensure the mountings are secure.

Should any adjustments be necessary, refer to the appropriate section under 'Settings and

Adjustments'.

without obstruction.

2. Proceed start the machine as described in Section A above.

If the machine is finished with or is to be left unattended, turn the Variable speed control knob

to the OFF position then disconnect from the mains supply.

OPERATION

SIMPLE TURNING

Before starting the machine, as described above, it is imperative 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 in order 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 micrometers/ verniers / cailpers etc.

Select a cutting tool that will produce the desired cut and mount in the tool rest, with as little over-

hang as possible, securing it using three hex socket head screws. (ideally, the overhang should

be approx. , 6mm but not more than 8mm for a straight tool).

It is IMPORTANT to ensure that the tip of the cutting tool is on the center line of the work, or very

slightly below it. On no account should it be above the center line.

Where necessary shims should be used beneath the tool in order to achieve the correct height, or,

if the tip is too high, the only recourse is to select another tool or grind down the tip.

To check the tip is at the correct height, position the tool so that the tip is almost touching the

point of the tailstock center. They should coincide. If necessary make adjustments using shims,

grind down the cutting tip or select another tool.

If the tailstock is not to be used, you may remove it completely by slackening off the securing nut

at its base, and sliding it free of the bed.
