7.6 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.
7.7 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.
