Use specific safety guards for vertical and angle grinders using Type 6 or Type 11 wheels.

(1) You must make sure the safety guard:
(a) Covers the wheel's plane of rotation toward the operator for at least one hundred eighty degrees;
(b) Covers the side of the wheel toward the driving flange for at least one hundred eighty degrees;
(c) Has a skirt which is adjustable to within one-eighth inch of the plane of the surface of the wheel.
(2) You must make sure not to use a "revolving cup guard."
Note:
"Cup back bushings" do not substitute for safety guards.
