Replacement Of Blade; Oil Level Check; Air Filter Maintenance - Solo 551 R Gebrauchsanweisung

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!
The blade fastening screw has a regular right-handed
thread. At re-assembly of the overload clutch be sure
and observe the sequence in which these parts where
previously assembled (illu.11). The blade screw is to be
tightened with the specified torque of 45Nm (4,5kpm).
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 (ill. 9).
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 (illustration 12).

Oil level check

Attention: The engine oil affects the lawn
mower's efficiency and life span. Never
operate the engine without oil or with little
oil. Major engine damage can occur. The optimum
viscosity depends on where the lawn mower is used (air
temperature and altitude) and can be found in the
engine owners manual.
Checking Oil level
1. Place lawn mower horizontally with all wheels on
the ground.
2. Turn oil tank cap counter-clock-wise (position 10),
and remove. Wipe off dipstick.
3. Place dipstick back into filler pipe.
4. Remove dipstick, hold horizontally and read oil
level. Oil level has to be between the "MAXIMUM"
and "MINIMUM" markings.
Changing Oil (Briggs&Stratton 4-cycle engine)
The engine oil may be drained via the oil drain screw
or the oil filler opening. Blade and blower wheel need
to be removed to reach the oil drain screw (illustration
13). Observe especially the service instructions in the
separate engine owners manual.
For the oil change with the HONDA OHC Engine, the
used oil is removed by suction which should only be
done by a specialist workshop.
When draining via oil filler opening (position 10):
Tilt the warm mower (with fuel tank empty and closed
oil filler ) slowly over the side of the filler opening.
Remove oil filler cap and catch old oil in a container.
Wait several minutes until oil is drained. Dispose off the
old oil in accordance with local ordinances.
Gearbox
Attention: The gear is equipped with a special
permanent oil and operates completely maintenance-
free. Technical faults that cannot be resolved by
adjusting the Bowden throttle cable are only to be
corrected by an authorized Service Center.
Attention! After changing oil, always wash
hands with a scouring agent, soap and
water. Never simply throw away used
engine oil and gear lubricant (environmental
protection). Collect used oil in authorized containers
and submit to the proper recycling facility.
Airfilter 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.
