Then fasten the blade guard (A) with 4 bolts (L) in the 
holder (N).

Fit the drive disc (B) on the output shaft.

Turn the blade shaft until one of the holes in the drive 
disc aligns with the corresponding hole in the gear 
housing.

•

Insert the locking pin (C) in the hole to lock the shaft.

•

Place the blade (D) and support flange (F) on the 
output shaft.

•

Fit the nut (G). The nut must be tightened to a torque 
of 35-50 Nm (3.5-5 kpm). Use the socket spanner in 
the tool kit. Hold the shaft of the spanner as close to 
the blade guard as possible. To tighten the nut, turn 
the spanner in the opposite direction to the direction 
of rotation (Caution! left-hand thread).

When loosening and tightening the saw blade nut, there 
is a risk of injury from the teeth of the saw blade. You 
should therefore always ensure that your hand is shielded 
by the blade guard when doing this. Always use a socket 
spanner with a shaft that is long enough to allow this. The 
arrow in the diagram shows the area where you should 

operate the socket spanner when loosening or tightening 
the nut.

•

Fit the trimmer guard/combination guard (A) intended 
for use with the trimmer head/plastic blades. Hang the 
trimmer guard/combination guard (A) on the two 
hooks on the plate holder (M). Bend the guard around 
the shaft and tighten it with the bolt (L) on the opposite 
side of the shaft. Use the locking pin (C). Place the 
locking pin in the groove on the screw head and 
tighten. See diagram.
