Checking operating safety

The lawn mower is equipped with a blade stop device.
Before every mowing job, make sure that the blade stop safety control bar is working
perfectly. When the control bar is released, the cutter bar must come to a standstill
within three seconds.
After release, the bar must always return to the position shown in the "component
description" diagram.
If this is not the case, it must be checked immediately by an authorised workshop.
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 mowing blade 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 switched off or the cutter bar has been stopped (depending on the model), 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. 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

The time at which lawnmowers may be used varies from region to region. Please ask
the corresponding authorities before using your mower.

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 grass collecting bag in no time.

Converting the machine to rear ejection (Illustration U2 + S1 )

– Switch the cutting deck off.
– Lift the ejection flap.
– Remove the mulching plug from the channel U2 .
– Hook the grass collecting bag in the bracket provided on the mower housing S1 .
The mulching blade system does not have to be converted! The capacity of the
collecting bag can be reduced under difficult mowing conditions (e.g. wet grass).
For the equipment to be used as a mulching machine again, the mulching plug must be
installed again. To do this, switch the cutting deck off, remove the grass collecting bag,
insert the mulching plug into the ejector channel and close the ejector flap.
Clean the ejector channel first.
