Selecting Wheels
Grinding is the cutting action of thousands of abrasive grains on the face
of a grinding wheel. When grinding metals such as steel and iron, choose
an aluminum oxide grinding wheel. Select a silicon carbide grinding wheel
for stone and concrete. Use cotton reinforced wheels for non-ferrous
metals.
1. When guard is properly positioned, place flange on spindle with
flange facing away from tool.
2. Place selected wheel on spindle and align with flange. Position flange
nut according to wheel thickness (Fig. 9, 10 and 11).
3. Press the spindle lock button while turning flange nut clockwise.
Tighten securely with the spanner wrench provided.
4. To remove wheel, unplug tool and reverse procedure.
To reduce the risk of injury, do not use the spindle lock
button to stop the spindle while the tool is in use or is
coasting after shut-off. This will result in tool damage.
