11. Maintenance
Changing the Belt
To replace the belt, the spindle shaft must be removed from the headstock.
This will allow the old belt to be removed and the new one installed.
Using a 4 mm hex wrench, open the headstock cover as shown in
Fig
11.6
and the motor pulley access hatch as shown in
Fig
11.7
.
Remove any accessories from the headstock spindle then remove the
headstock handwheel by removing the 2 blind set screws located opposite
each other in the shaft with a 3 mm hex wrench,
Fig
11.8
.
Remove the speed sensor from inside the headstock by removing the two
countersunk screws from the side of the headstock as shown in
Fig
11.9
. The
sensor will drop down and away from the spindle and pulley, reducing the
possibility of damage to it.
Remove the 2 blind set screws that hold the pulley to the spindle using a 3
mm hex wrench,
Fig
11.10
. Note that the 2 screws are stacked one on top of
the other to give optimum securing of the pulley to the spindle.
