Replacing the Grinding Wheels
1. To replace the grinding wheel, loosen the three cross head screws on the
outer side of the hood and remove the protection hood.
2. Now loosen the main retaining nut of the stone with a suitable open end or
ring spanner.
3. The treads on the left hand side are left hand treats; the nut is loosened by
turning clockwise. Be careful not to confuse the nuts when putting them
down. Hold the wheel in place to prevent shaft and wheel from turning.
Then loosen the nut.
4. After the nut has been removed, pull the outer flange and the grinding
wheel with the paper liners off the shaft.
5. Before mounting, check the new wheel visually and acoustically for
damage. Visually check for cracks. After the visual check, gently strike the
wheel with a hard object. The sound must be clear and identical on all parts
of the wheel. If the sound is dull, the wheel is probably cracked and should
not be used. Do not use a cracked wheel, it is not able to withstand the
loads of use and may suddenly break up during use.
6. Mount the wheel as pictured below.
