6.2 Guard
▶ Observe the instructions for fitting the applicable guard.
6.2.1 Installing the guard
The guard is keyed to ensure that only guards of a type suitable for use with the product can be
installed. The keyed locating lug also prevents the guard from coming into contact with the tool.

The guard is preset to the correct clamping diameter by the adjusting screw. If tension is too low
when the guard is fitted, the adjusting screw can be tightened slightly to increase the clamping force.

2. Rotate the guard to the required position.
3. Secure the guard by closing the clamping lever.
