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 correct trimmer guard (A) for use with the trimmer 
head. CAUTION!  Ensure that the guard extension is 
fitted. 

Hook the trimmer guard/combination guard onto the fitting 
on the shaft and secure with the bolt (L).

•

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.

•

To fit the trimmer head, first separate the two halves (see 
diagram). Proceed as follows: 

-

Insert a finger into the centre hole of the cover (I) while 
grasping the cover with your other fingers. Using the 
index finger and thumb of your other hand, release the 
two catches (J) that engage in the cut-outs in the 
bottom half (K). Pull apart the trimmer head, grasping 
the cover firmly.

•

Place the cover (I) and the support flange (F) on the 
output shaft.

•

Fit the nut (G). Tighten the nut to a torque of 35-50 Nm 
(3.5-5 kpm). Use the socket spanner in the tool kit. Grasp 
the handle of the spanner as close to the trimmer guard 
as possible.

•

To tighten the nut, turn the spanner in the opposite 
direction to the direction of rotation (Caution! left-hand 
thread).

•

Fit the bottom half of the trimmer head (K) to the cover (I) 
by pressing them together, with the cut-outs on the bottom 
half aligned with the catches on the cover.

•

To dismantle, follow the instructions in the reverse order.

•

Fit the trimmer guard/combination guard (A) intended for 
use with the trimmer head/plastic blades. CAUTION!  
Ensure that the guard extension is fitted. 

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.

•

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.

•

Screw on the trimmer head/plastic blades (H) in the 
opposite direction to the direction of rotation.

•

To dismantle, follow the instructions in the reverse order.
