Step 1: Remove all accumulated residue in the guards 

and around the assembly mandrel.

Step 2: Clean the inner flange of the mandrel (Fig.4) 

Align the flange so that the correct side faces 
the saw blade and place the new saw blade 
on the shaft. Make sure that the teeth are poin-
ting forward.  

Step 3: Place the outer mandrel flange on the mandrel 

with the correct side towards the saw blade.

Step 4:Replace the saw blade holding screw and 

tighten it hand-tight by turning it clockwise. 

Step 5: Push the mandrel locking lever in and turn the 

mandrel by hand until the lock engages the 
mandrel. Tighten the saw blade holding 
screw. Turn the arbor with the spanner to en-
sure that the arbor lock has loosened and re-
lease the arbor lock.

7.5 Removing the saw blade

Removal is in the reverse order to the installation of the 
saw blade. However, special care must be taken to en-
sure that no one is injured by the saw blade.

Step 1: Push the saw blade locking lever in and turn the 

shaft with the spanner on the holding bolt until 
the lock engages the shaft. Loosen the saw 
blade holding bolt with the spanner supplied 
and release the mandrel lock.

Step 2: Loosen the saw blade holding screw completely 

and lift it and the outer flange away. Make sure 
that the saw blade does not fall down.

Step 3: Carefully turn the lower blade guard out of the 

way. The saw blade can now be removed.

7.6 Setting the cutting depth

Set the required cutting depth. A depth scale is availa-
ble. 

Step 1: Release the depth adjustment locking lever.

Step 2: Set the value to the required depth.

Protective gloves

Wear protective gloves for all work connected with 
the saw blade.

NOTE!

Use saw blades with a suitable arbor hole. The saw 
blade must be designed for the maximum nominal 
speed of the machine or higher. Avoid contact with 
the blade teeth to prevent injury.

NOTE!

Make sure that the saw blade is centred (it is possi-
ble to tighten the saw blade at an angle between the 
flanges).

WARNING

Disconnect the machine from the electrical mains 
before adjusting the cutting depth.
