Maintenance and Care
ENGLISH 15
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.
11.6 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:
Observe the notes and instructions in the type-speci.c
engine operating instructions.
• Place lawn mower
horizontally with all
wheels on the ground.
• Turn oil tank cap counter-
clock-wise (14), and
remove. Wipe off
dipstick.
• Place dipstick back into
filler pipe.
• 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 11).
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 wich should only be
done by a specialist workshop.
When draining via oil filler opening (14): 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.
After changing oil, always wash hands with a scouring
agent, soap and water.
Attention: 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.
Gearbox (550R / 550HR / 550RS)
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.
11.7 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.
