11. Operation
Disengage the spindle lock by lifting the indexing dial and rotating to a
position where it is not located in the recess then lowering,
Fig 11.21
.
Spindle Indexing Reference Chart
The chart opposite gives a useful reference guide to basic indexing, showing
the standard 8 divisions of the indexing system, the angle between positions
and also the spindle index positions to use.
Operating the Lathe
Before turning the lathe on, ensure the off switch has been rotated clockwise
and is in the raised position.
To turn the lathe on, press the on switch as shown in
Fig 11.22
.
To turn the lathe off, press the off switch.
To cut off power from the control box, press the off switch on the electrical
enclosure box as shown in
Fig 11.23
.
To supply power to the control box, press the on switch on the electrical
enclosure box as shown in
Fig 11.23
.
To adjust the speed ensure the drive belt is placed in the correct position to
achieve the required speed,
Fig 11.13
. Use the speed control dial to adjust
the speed of the lathe within the range allowed by the drive belt position.
The speed of the lathe spindle is shown on the speed readout.
To run the lathe in the standard
forward
direction, turn the forward /
reverse selector
anti-clockwise
.
To run the lathe in
reverse
, turn the forward / reverse selector
clockwise
.
WARNING
Extreme caution must be exercised when turning in reverse as
not all lathe accessories are designed to be used for reverse
turning. Always ensure accessories are suitable for this use and
that all relevant securing items (such as blind set screws) are
fitted correctly. If standard woodturning accessories are used
with the lathe running in reverse there is a risk they could come
away from the lathe and cause serious harm to the user.
In the Event of a Blockage or if the Machine Stalls
If the lathe stalls due to a dig in, simply removing the turning tool from the
work piece will normally allow the lathe to start turning again.
In the event of a blockage (for example, if the work piece becomes trapped
against a fixed part of the machine) switch off the machine immediately, by
pressing the off switch.
Locate and rectify the source of the blockage and ensure that the work piece
can be rotated freely by hand before attempting to re-start the machine.
To re-start the machine, press the on switch.
In the Event of a Power Failure
The lathe is fitted with a no volt release (NVR) switch to protect the user
against automatic starting of the machine when power is restored after a
power failure.
In the event of a power failure, first locate and rectify the source of the
failure. If the fault is within the power circuit of the workshop, there may be
an underlying cause (circuit overload etc.) that should be investigated by a
qualified electrician, before attempting to restore the power source.
Once the power is restored, the machine can be re-started by pressing the
on switch.
