DISMANTLING (fig. 44)

REMOUNTING (fig. 45)
Place the blade on the pins and fasten it to the shaft with the bolt and washers. The large
washer (3) must be fitted with the bent side of the blade. During assembly, be careful not to let
the driver’s cage fall (5).
TIGHTENING THE SCREWS
- the screw has a right (classic) thread. Tighten clockwise.
GRINDING AND BALANCING THE BLADES
For best results your blade should be sharp. The blade may be resharpened by removing it and
either grinding or filing the cutting edge keeping as close to the original bevel as possible. It is
extremely important that each cutting edge receives an equal amount of grinding to prevent
an unbalanced blade. Improper blade balance will result in excessive vibration causing eventual
damage to the engine. The blade can be tested for balance for example by balancing it on
a round shaft screwdriver. Remove metal from the heavy side by grinding until it balances evenly.
BELT REPLACEMENT
C The belt must be replaced by a specialist service centre, preferably an authorised
service centre.
• Belts must be replaced if they show visible signs of wear. Always use genuine belts.
