d. Adjust the cable (fig. P)
If the control cable for the transmission is out of sync and has too much
play, you can fix it.
- Loosen the small lock nut (32a).
- Turn the adjusting nut (32b) counter clockwise: The control cable is
shortened.
- Turn the adjusting nut (32b) in a clockwise direction: The cable is
extended.
e. Sharpen/change the blades
- Remove the spark plug from its socket and inspect the blade for
wear or damage.
- Always make a blunt blade sharpened by a specialized garage as it
can perform an unbalance check.
- Always sharpen a blade or replace an unbalanced blade with a
specialist. Incorrect mounting may cause serious. The replacement
of the blade shall not be done by the operator.
Instructions for sharpening and changing the blade
WARNING: Wear gloves, turn off the engine and remove the spark
plug before proceeding.
The blade is made of hardened steel. To get a clean job, sharpen the
blade frequently, about every 25 hours of use. Make sure the blade
is always well balanced.
Insert a small iron pin (2 or 3 mm in diameter) into the hole in the
middle of the blade: it must remain horizontal. If the blade does not
stay horizontal, balance it by sharpening it further on the side
where it is leaning.
WARNING: Use only original spare parts. Poor quality replacement
