6. Wheels should be dressed periodically to maintain grinding
efficiency, especially if they become clogged from grinding
soft metals. Use a grinding wheel dresser to restore the
wheel’s original shape.
6.1 Dress the grinding wheel face only. Dressing the wheel
sides can cause it to become too thin for safe use.
7. Keep all parts in working order. Check to determine that
the guard or other parts will operate properly and perform
their intended function.
8. A guard or other part that is damaged should be properly
repaired or replaced. Do not perform makeshift repairs.
9. Disconnect tool when changing grinding wheels.
10. Replace a cracked wheel immediately and use only the
flanges supplied with the grinder.
11. Replacement wheels must have a minimum rated speed of
3,450 RPM and a maximum diameter of 6 in.
WARNING! Only qualified service personnel should repair the
tool. An improperly repaired tool may present a hazard to the
user and/or others.
WHEEL DRESSING
A grinding wheel may become unbalanced due to irregular
wear or it is loaded with ground material. The grinding wheel
must be trued and dressed.
Truing or dressing the wheel is best done using a star-wheel
dresser, a silicon carbide stick type dresser or a diamond faced
dressing tool.
Dress the wheel by moving the dresser forward on the tool rest
until it just touches the highpoint on the face of the wheel, then
dress the wheel by moving the dresser back and forth across
the wheel face.
Repeat this procedure until the face of the grinding wheel is
clean and the corners of the wheels are square.
