DeWalt D28111 Instruction Manual page 27

NOTE: The guard is pre-adjusted to the diameter of the gear
case hub at the factory. If, after a period of time, the guard
becomes loose, tighten the adjusting screw (O) with clamp
lever in the closed position with guard installed on the tool.
CAUTION: Do not tighten the adjusting screw with the clamp
lever in the open position. Undetectable damage to the guard or the
mounting hub may result.
CAUTION: If the guard cannot be tightened by the adjusting
clamp, do not use the tool. To reduce the risk of personal injury, take
the tool and guard to a service center to repair or replace the guard.
