Maintenance and care

10.6 Mowing Blade
Special tools, such as a torque wrench for
example, are required to mount the blade to
the mower. For safety reasons we recommend
that the mowing blade is sharpened, balanced and
re-fitted by an authorized specialist workshop only.
The following notes are therefore only intended for
specialist repair shops.
To obtain best mowing results we recommend to
have the blade sharpened / balanced or at least
once every year.
Replacement of Blade
Proper gloves are to be worn when
replacing the blade. The spark plug
cap has to be removed prior to any
work.
When replacing any blade parts only SOLO spare
parts are to be used. The identification No. on the
blade has to agree with the Order No. for the
replacement. Never install a different type of
blade!
Use the holding pin as a blocking device for the
blade. The blade fastening screw has a regular
right-handed thread. To remove the screw we
recommend using a socket wrench 21 mm (spark
plug wrench) or hex. wrench 8 mm, 5/16“. At re-
assembly of the overload clutch be sure and
observe the sequence in which these parts where
previously assembled. The blade screw is to be
tightened with the specified torque of 45Nm
(4,5mkp).
Damaged Blade
The engine needs to be shut off and the spark plug
cap has to be removed if the blade has come in
contact with a foreign object or other obstacle.
After the blade stops, tilt the mower and check the
blade for damage. Deformed or bent blades are not
to be re-aligned.
Damaged parts are to be replaced immediately. If
the mower has been driven over a notable
obstacle, the mower needs to be checked by an
authorized Service Center. Prior to use make
certain that blade and blade fastening parts are not
damaged. If necessary, parts need to be checked
or replaced. Never operate mower with an
unbalanced blade - this would cause vibration and
additional damage.
Sharpening of Blade
Attention: The blade may be sharpened with a
metal file; however, we recommend that
resharpening/sanding is done by an authorized
Service Center who will pay attention that the same
amount is sanded off on each side to avoid any
imbalance.
The cutting edge of the blade is only be resanded
up to the imprinted markings.
10.7 Air filter maintenance
Attention: Dirty air filters reduce the engine‘s
efficiency, the carburetor does not receive
sufficient air flow. Routine inspection, especially in
dusty conditions, is essential.
Attention: Never clean air filter parts with gasoline
or flammable solvents. Danger of fire or explosion!
Observe all instructions in the respective engine
owners manual.
