MAINTENANCE OF KNIVES
The mower is equipped with blades made to last for a long time. If a knife loosens or breaks
down, it is important to replace it immediately. If not, there is a possible imbalance, which is
very serious. If it is partly or completely worn out, it should be replaced to maintain the correct
weight balance. Use of dull blades reduces the cutting efficiency and increases fuel consump-
tion. Replacing of the blades is done as following:
A) Make sure the engine is off and the blades do not rotate. Turn off the fuel valve and allow
the engine to cool for five minutes. Remove the spark plug to be sure that the engine can not
start.
B) Raise the mower to its maximum cutting height.
C) Gently raise the mower into a slightly inclined position. IMPORTANT! Ensure that the mower
can not tip over.
D) Loosen and remove the bolts.
E) Replace blades.
F) Insert the bolts properly, and check that the blades can move properly on the shoulder.
IMPORTANT! Never use worn, cracked or repaired knives. Replace with new ones.
IMPORTANT!
For repairs beyond the previously listed adjustments, please contact your local dealer.
