Retract the tool one or two complete turns on the cross-slide feed, then wind
the saddle so that the tool is at the start point once again. Advance the tool
the same number of turns, plus the depth of cut, and when ready, turn the
Power Drive Control knob clockwise to engage the clutch again and procede
to take another cut.
MAINTENANCE
For maximum performance, it is essential that the lathe is properly maintained.
BEFORE USE
Always inspect before use. Any damage should be repaired and maladjustments
rectified. Damage to machined surfaces should be repaired with an oil stone. Test
by hand to ensure smooth operation of all parts before use.
AFTER USE
Remove all swarf from the machine and thoroughly clean all surfaces. If coolant
has been used, ensure it has been completely dried off.
All machined surfaces should be lightly oiled.
Always remove cutting tools, and store in a safe place.
PERIODICALLY
Unscrew the cross slide as far as possible, and when the adjuster thread has become
disengaged, gently tap off the slide, taking care to retain the jib strip (refer to cross
slide adjustmentrs - page 17). Thoroughly clean, then oil the machined surfaces.
Re assemble ensuring the jib strip is correctly inserted and adjusted where necessary.
MOTOR BRUSHES
The Motor brushes may be changed by unscrewing the caps, visible at the top and
bottom of the motor. The caps are accessible once the motor cover, secured by
two screws, is removed.
To change the jaws, insert the chuck key and
open the jaws to their fullest extent. It will then
be possible to remove each jaw in turn.
Replace them with the external jaws, noting the
following.
The thread segments of the jaws are progressively
‘stepped’ as shown in FIG 9. They are also
numbered 1 to 3. This is to take into account the lead of the screwthread within
the chuck. It is therefore necessary to assemble the jaws in the correct order.
Arrange them as shown in the FIG.9, and assemble in the same order, clockwise in
the slots in the chuck, turning the chuck key as you insert them. Close the jaws fully
and check to ensure they all meet at the centre. If a jaw is out, open the jaws fully,
and retain pressure on the jaw in question whist turning the chuck key, until it
snaps down into position. Re-check to ensure all jaws meet at the centre
