The grinding stone will wear down with use and may well go out of true. Use a
dressing wheel or stone grader to correct the trueness and to remove worn,
glazed grains from the stone.
The stone will have a finite life expectancy, dependant upon the nature of the
work being done. Periodically, make a note of the wheel diameter and
replace your (150mm) dia wheel if it reduces to an little as (130mm) in
diameter.
INSTALLING A NEW GRINDING WHEEL
To renew or change the grinding wheels, proceed as follows
1. Switch off and un-plug from power supply. Remove the grinding wheel
covers by unscrewing the nuts securing the three retaining screws.
2. Remove the spark arrester bracket and eye shield by unscrewing the single
mounting screw. Slacken the tool rest mounting bolts, and pull the bracket
away from the wheel.
3. Hold the sanding belt roller firmly to stop the shaft rotating and remove the
nut and flange holding the grinding wheel, remembering that the nut has a
LEFT HAND THREAD.
4. Remove the used wheel and replace with a new one, ensuring that:
• The paper blotters and flanges are in place either side of the wheel.
• You do not overtighten the wheel nut.
5. Re-adjust the tool rest and spark arrester brackets.
6. Switch the machine on and allow it to rotate freely for at least one minute.
