Risk of injury!
If the blade run-on time is longer, stop using the equipment and take it to an authorised
workshop.
Measuring run-on time
After the engine has been started, the blade rotates and a wind-like noise can be heard.
The run-on time corresponds to the duration of the wind-like noise after the engine has
been stopped, it can be measured using a stopwatch.
Machine safety and protective devices must not be manipulated or disabled.
The perfect function of the motor drive control bar must be checked before every
mowing job too. When the motor drive control bar is released, the machine must come
to a standstill immediately. If this is not the case, it must be checked immediately by an
authorised workshop.
Make sure that all protective devices have been attached properly and are not
damaged.
To avoid risk, check the condition and firm attachment of the blade before every
mowing job. The blade attachment screw must always be tightened by an authorised
workshop. If the blade screw is too tight or too loose, the blade coupling and cutter bar
can become damaged or loose which can lead to serious injuries. A worn or damaged
blade must always be replaced. (Refer here to the chapter "Cutter blade care").
In addition, check the fan, blade coupling and fan housing every 10 operating hours for
wear and a tight fit. Also check equipment screws and nuts for a firm fit and tighten if
necessary.
Make sure the spark plug connector is fitted tightly. Danger: Electric shock. Never
remove the spark plug connector when the motor is running. Danger: Electric shock!
Disconnect the spark plug connector only when the engine has cooled down. Danger of
burns!
If the mower mechanism becomes blocked e.g. by colliding with an obstacle, have an
authorised workshop check whether any parts of the mower are damaged or deformed.
Always have any necessary repairs done by an authorised workshop too.
If the machine starts to vibrate unusually heavily or to make unusual noises, please
have it checked immediately by an authorised workshop.

Time restrictions

In Germany, the set hours for operating lawnmowers are regulated in the "32nd
Ordinance implementing the Federal Emissions Protection Act (32nd BImSch-V)".
In addition, there may be regional restrictions (e.g. to protect midday peace), which can
be issued by the respective local authority.

Tips on caring for your lawn

Mowing (Illustration M )

WARNING
Remove any objects (stones, wood, branches, etc.) from the lawn before each
cut; but still watch out for objects lying around during the mowing process.
Ask your dealer about lawn care instructions. Information and instructions about
mowing can also be found on the manufacturer website.

Mulching

Your lawn mower can also be equipped with a mulching kit. The respective conversion
kit to a mulching system is available as an accessory from professional dealerships
(see genuine spare parts and accessories for the conversion kit order no.).
The mulching kit also includes tips and information about mulching. You will also find
information about mulching on the manufacturer website.
WARNING
Always have an authorised workshop carry out the conversion of the mower to a
mulching system. A wrongly assembled cutting blade coupling or a blade screw
that is tightened too tightly or too loosely can allow the cutting blade bars to
become loose and cause severe injuries.
If the grass should happen to be too high for mulching, the mulching mower can be
converted for mowing with a side ejector in no time.

Converting the machine to side ejection (Illustration R3 )

– Stop the engine and remove the spark plug.
– Remove the cover plate (1) from the right-hand side of the housing.
To do this loosen the two self-locking nuts (2) and pull the washers (3) off, pull the
two flat round screws (4) out from the inside (cutting space) and remove the cover
plate.
The mulching blade system does not have to be converted.
For the equipment to be used as a mulching machine again, the cover plate (1) must be
replaced.
IMPORTANT
Before fitting the cover plate, clean the channel and remove remaining grass and
dirt from the insider in order to ensure that the plate can be firmly and correctly
seated.
Insert the cover plate into the housing from the inside in such a way that the two bore
holes in the cover plate are aligned with the bore holes in the housing. Insert the two flat
round screws (4) into the bore holes from the inside (cutting space), put the washers (3)
in place and tighten using the two self-locking nuts (2).
WARNING
Never use the equipment with the deflector damaged or missing.
Always work with the deflector closed (folded downwards) even when the
machine has been converted for mulching.
