a. Turn the ‘Emergency Stop so that it springs out.

b. Turn the ‘Forward/OFF/Reverse’ switch to Forward or Reverse.

c. Turn the ‘Power Drive’ control knob, which drives the Leadscrew, to the ‘HAND’

position.......NO Drive.

IMPORTANT: This should ALWAYS be a deliberate,conscious action.

d. Turn the ‘Spindle Speed Control’ knob fully anticlockwise until it clicks into

the OFF position.

e. Turn the Lathe/Drill/Mill Head switch to ‘Cutting’for Lathe operation, ‘Milling/

Drilling’ for Milling/Drilling operations.

2. Ensure the toolpost is well away from the chuck,....... turn the ‘Feed’ handles

(Saddle and/or Cross Slide), anticlockwise until it is well clear, then, ensure the

Chuck Guard is fully in the DOWN position.

NOTE: The Chuck Guard is fitted with a microswitch, which will prevent the

machine from operating until it is in the ‘down’ position.

3. Ensure all tools or loose parts are removed, then plug in to the mains supply. The

lamp on the panel should illuminate.

4. Turn the ‘Spindle Speed Control’ knob slowly clockwise. A click will be heard

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.

5. Run for a total of 5 minutes, during which time gradually increase spindle

speed to its maximum. Run for at 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.

B. STARTING UNDER NORMAL CONDITIONS (ref. FIG. 4)

1. Mount the workpiece ensuring it is perfectly secure and, importantly, can

rotate fully without obstruction.

2. Taking all necessary precautions previously stated, proceed to start the machine

as described in Section. A above.

NOTE: If Auto feed is required, then turn and hold the Power Drive switch fully

clockwise, until the clutch engages. To disconnect the drive.....turn the switch

ANTIclockwise.

C. SWITCHING THE MACHINE OFF

The simplest method to turn the machine OFF, is to hit the ‘Emergency’ Stop.

Alternatively turn the Forward/OFF/Reverse switch to OFF, or turn the Spindle Speed

Control knob fully anticlockwise until it clicks in the OFF position.

Whichever method is used, OR if the machine should stop for any other

reason....power failure, or if the Thermal Overload intervenes, it will be necessary to

restart by turning the Spindle Speed Control knob fully anticklockwise until it clicks

OFF, then clockwise again to start.
