The extension (J, Fig 40) mounts to the tool rest base and
offers greater reach for the tool rest when turning off the
bed using the headstock at an angle, as shown.
Make sure the clamp bushings (K) are pulled apart
sufficiently to accept the post of the extension.

7.7 Adjusting tailstock

Turn the hand wheel (R, Fig 41) clockwise to move tailstock
spindle forward. Lock tailstock spindle with the indexable
knob (Q).
The handle (P) locks the tailstock in position on the bed.
The live centre (S) can be ejected by turning the hand
wheel counter-clockwise.
The live centre pin can be removed to allow deep hole
drilling operations.

8. Maintenance and inspection

General notes:
Maintenance, cleaning and repair work may only be
carried out after the machine is protected against
accidental starting by pulling the mains plug.
Clean the machine regularly.
Inspect the proper function of the dust collection daily.

Defective safety devices must be replaces immediately.
Repair and maintenance work on the electrical system may
only be carried out by a qualified electrician.

8.1 Adjusting bed clamping

If adjustment is needed, remove the stud (N, Fig 3).
Slide the headstock, tailstock or toolrest to the edge of the
bed and slightly turn the hex nut (F, Fig 42).
Test the handle to make sure it securely locks.

8.2 Changing belt and bearings

Changing belt and bearings can be a difficult task. By
chance remove headstock and take into a repair station
for servicing.
Disconnect the machine from the power source.
Open the door and remove the belt from the lower pulley.
Loosen two set screws (C Fig 43) and unscrew the hand
wheel.
Use a wood dowel, or aluminium stock to knock spindle
towards the tailstock. (Use a material that is softer than the
spindle so you do not mushroom end of spindle).
Go only far enough to remove the belt from spindle.
To reassemble reverse the procedure.
