NOTE
The guard is already set to the correct tension by way
of the adjusting screw. If the tension is too low when
the guard is fitted, the adjusting screw can be tightened
slightly to increase the tension.
NOTE
The keyed locating lug on the guard ensures that only
a guard designed for use with the power tool can be
fitted. The keyed locating lug also prevents the guard
from coming into contact with the disc.
1. Release the clamping lever.
2. Fit the guard onto the spindle collar so that the
keyed locating lug engages in the recess provided.
3. Rotate the guard to the required position.
4. Secure the guard by closing the clamping lever.

the material you are working on. Abrasive discs generally
have to be replaced when the durability date has been
reached.
