1.5.2 Tightening screw connections
Check all important screw connections regularly for tightness. Before each use of the machine, always check the tightening of the screws
securing the blade to the blade holder and also the blade holder to the drive shaft Fig. 12.

Tighten the bolts securing the blade to the specified tightening torque - see description Fig. 12 !

When replacing screws, use only original spare parts supplied by the manufacturer!

The central screw M10x1x25 has a fine thread, therefore it must not be confused with the outer screws with a
normal thread!
1.5.3 Replacing and sharpening the blade

The machine must be standing on a solid base and secured such that it allows good access to the blade and
spontaneous movement of the machine does not occur.

Take particular care when removing the blade. The blades edges are sharp. Protect hands with work gloves.

The engine must be switched off and the spark plug lead removed!
The replacement procedure is as follows (always work with an assistant):
●
Loosen and remove the outer screws 4 . Then loosen and unscrew the center screw 3 and remove the blade 2 and the blade
holder 1 from the blade shaft.
●
Align and sharpen the edges. The inclination of the sharpened edge should be 25 ° in relation to the lower plane of the blade.
The blade must be well balanced even after sharpening, so be sure to remove the material evenly when sharpening on both edges.
●
Install the blade and the blade holder back on the blade shaft in reverse order.

The central screw M10x1x25 has a fine thread, therefore it must not be confused with the outer screws with a
normal thread!

New spring washers must always be used under the screws (see spare parts list).

On the thread of the central screw M10x1x25, apply a thread-securing adhesive (eg. LOCTITE 243)!

Tighten the bolts to the specified tightening torque.

If excessive vibration occurs on the handlebars of the machine after mounting, it is essential to rebalance the
blade!

In case of any unprofessional repair or modification of the blades without the use of original spare parts, the
manufacturer is not liable for damages caused by the machine.
