CHANGING BLADES
Use protective gloves to prevent cuts
when changing blades.
Blunt and damaged blades tear off the grass and
spoil the look of the lawn after mowing.New, well
sharpened blades cut the grass cleanly, so that the
lawn looks green and fresh even after mowing.
Always check the blade after an impact. First
disconnect the ignition cable. If the blade system
has been damaged the defective parts must be
changed. Always use genuine spare parts.
To replace the blade, slacken the screw (fig. 16).
Fit the new blade so that the stamped STIGA
logotype is turned facing the blade attachment (and
not facing the grass). Refit as illustrated. Tighten
the screw fully to a torque of 40 Nm.
When replacing the blade, the blade screw should
also be replaced.
The guarantee does not cover damage to the blade,
blade holder or engine caused by running into
obstacles.
When replacing the blade, the blade holder and
blade screw, always use original spare parts. Non-
authentic spare parts could lead to the risk of
personal injury or damage, even if they fit the
machine.
SHARPENING OF THE BLADES
Sharpening of the blades must be done by wet
method grinding, using a whetstone or a
grindstone.
For the sake of safety, the blades should not be
sharpened on an emery wheel. A very high
temperature could cause the blade to become
brittle.
Once the blade has been sharpened, it
must then be balanced so as to avoid
vibration damage.
STORAGE
WINTER STORAGE
Empty the fuel tank. Start the engine and let it run
until it stops. The same petrol must not remain in
the tank for more than one month.
Tip up the mower and screw out the sparking plug.
Pour a teaspoon of engine oil in the sparking plug
hole. Pull out the starting handle slowly so that the
oil is distributed in the cylinder. Screw in the
sparking plug.
Thoroughly clean the mower and store it indoors in
a dry place.
SERVICING
Genuine spare parts are supplied by service
workshops and by many dealers.
