2. Clean all clamping and centering surfaces on the cut-off saw and the cut-off wheel.
3. Check that the mounting flange and the clamping flange are correct for the cut-off wheel.
▶ Change the mounting flange if necessary.
4. Position the cut-off wheel flush and centered on the mounting flange.
▶ The cut-off wheel's direction of rotation matches the direction-of-rotation arrow.
5. Position the clamping flange flush and centered and install the securing screw.
6. Insert the locking pin into the hole in the belt cover.

▶ Tightening torque (securing screw) → Technical data
9. Remove the locking pin.
After installing a new cut-off wheel, start the cut-off saw and allow it to run without load at full
speed for approx. 1 minute. Check for roughness in operation or vibration; if a cut-off wheel is
damaged it will generally break during this test run.
5.5 Removing the cut-off wheel
WARNING
Risk of injury and damage. Damaged cut-off wheels may break.
▶ If the cut-off wheel has been subjected to an impact, check the cut-off wheel for damage and replace it
if necessary.
▶ Never use cut-off wheels that are damaged, run untrue or vibrate.
▶ Don't use synthetic resin-bonded fiber-reinforced cut-off wheels which have exceeded their use-by date
or already softened due to water absorption.

5.7 Preparations for dust extraction module
5.7.1 Installing dust extraction module (accessory)
Used in combination with an industrial vacuum cleaner, the dust extraction module reduces the amount of dust
created by dry-cutting operations. Use the dust extraction module only for dry-cutting in mineral materials.
The severe heat produced by cutting in metals or use for wet cutting will destroy the dust extraction module.
Read and observe the instructions on safety and use in the operating instructions of the accessory.
1. Clean the blade guard and the notches for installation of the dust extraction module.
2. Move the blade guard until the installation position of the dust extraction module is freely accessible.
3. Slacken the nut on the dust extraction module until the housing parts can be opened as far as the end
stops on the connecting axle.
4. Engage the dust extraction module in the notches provided for the purpose in the blade guard.
▶ The notches slide smoothly into engagement without jamming.
