Tool Changing
Draw bar secured tooling
Make sure the power is switched off or better still removed from the machine. Unclip the drive
belt cover and raise clear (See Fig 3). Hold the quill locked, either by holding the pulley tower
(use the heel of the break taper drift in the quill against the spindle sleeve?). Using the supplied
spanner loosen the draw bar nut, unscrew the draw bar several turns, and then strike the draw
bar nut to break the taper lock of the tool and the spindle. Unscrew the draw bar from the tool.
Ensure the tool is supported, i.e. will not fall on to the workpiece/table et al. When it is free put
the tool carefully aside, withdraw the draw bar, check the thread, check the taper and the thread
of the new tool are clean and undamaged, check the draw bar is the correct one, introduce the
new tool into the taper, re-insert the draw bar and screw into the top of the tool. Screw in the
draw bar finger tight. Hold the quill immoveable and tighten with the spanner. DO NOT
OVERTIGHTEN. Remove all tooling, re-secure the drive belt cover, re-connect the machine.
Ensure the tool path is clear, switch on, and check that the tool correctly seated, is running true
etc. If all is O.K,proceed.
Fitting the Drill Chuck
Remove the draw bar secured tooling. Put carefully aside. Assemble the drill arbor and the drill
chuck together. Check the tapers, both on the drill arbor and in the spindle are clean. Align the
tang with the release slot and push the assembly smartly into the spindle. Check the tapers have
locked. Proceed, using the mill as a drill press. To release the drill chuck assembly after use,
introduce the taper break drift into the slot in the sleeve, tap forward until the tapers break lock.
Ensure the drill chuck is supported before breaking the lock.

Along the Traverse Axis (Y)
Milling or Drilling Vertically (Z)
Changing Speed
Switch the machine off. Switch off the supply, and/or disconnect the machine from the supply.
Unclip the two toggle clips then take out the infill cover (a) and lift the lid of the drive belt cover
(b) see Fig 10. Loosen the motor yoke clamp handle, push the motor forward to release the
tension on the belts. Move the belts clear of the pulley towers, now is a good time to check the
drive belt for wear and give the drive belt and pulley enclosure a good clean. (If it needs it? There
are sometimes rubbings from the belts and general dust and debris.) Refer to the Speed Select
Table and ascertain the belt positions for the speed you require (See Fig 11). Move the belts to
these positions, commence the tensioning operation by pushing the jockey pulleys to tension
the driven to jockey belt (Have a care not to trap fingers, the pulleys are free to move). Tension
the whole belt train by pushing/levering the right side of the motor away from the main
18
casting.
