2° FITTING THE BLADES
The EL 50 N Power Tiller is equipped with curved blades.
The blades can be fitted in two different ways, depending on the job to be done :
- 3 pairs of blades per flange (fig. 17 a) :
3 right blades (D) and 3 left blades (G) (as fitted at the factory)
- 2 pairs of blades per flange (fig. 17 b) :
2 right blades (D) and 2 left blades (G).
To recognise if the blades are right (D) or left (G), hold the blade with the bolt holes facing downwards, point the
cutting edge in the direction of rotation (F) and note the direction of their curved portion.
A = machine forward direction (fig. 18).
To fit blades helicoidally, proceed as follows :
- Always start fitting each flange with the same type of blade, placing it opposite mark (R), shown by a chamfer
or a hollow (see fig. 17) ;
- all blades should be fitted on the left face of the flanges (see fig. 18).
- Fixing bolt heads should face the blades, washers and nuts should face the flanges.
