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 cutter bar has stopped, it can be measured using a
stopwatch.
The function of the safety control bar must never be put out of
operation.
It is important to make sure that the safety control bar functions
correctly. If this is not the case, have it repaired by an authorised
specialist workshop.
To ensure proper operation of safety equipment, the control bar, the
control housing with throttle cable and the blade brake must be
checked regularly at least once per mowing season by an authorized
professional workshop.
Protective equipment includes (see chapter Component description):
– Housing, grass collecting bag, ejection flap (
The protective devices protect the user against objects being ejected at
high speed.
The machine must not be operated with a damaged housing or without
a properly fitted collecting bag or deflector plate, or ejection flap on the
housing.
– Housing
This protection unit protects against injuries through contact with the
rotating cutting blade bar.
The equipment must not be operated with a damaged housing. Please
make sure that hands and feet are not placed underneath the housing.
– Belt drive covers ( ), engine covers (
12
These protection units protect against injuries through moving parts.
The equipment must not be operated with damaged covers or without
correctly attached covers.
– Exhaust protection grill (
The engine/exhaust becomes very hot. The protection grill protects
the user against burns.
Do not operate the machine without the exhaust protection grill.
The safety devices must not be modified.
• Do not change the basic settings of the engine or operate the engine at
excessive speed.
• During the starting process, do not switch on the drive if available.
When you start the machine, make sure that your feet are at a sufficiently
safe distance away from the cutting blades.
When the mowing blade is switched on, the machine must not be tilted on
end; if necessary it must be tilted by pressing the guide bar down so that
the cutting tool is pointing in the direction away from the user, but only as
far as absolutely necessary. As long as the mower has not been lowered
to the ground again, both your hands must be on the top part of the bar.
Never put your hands or feet near or under revolving parts. Always make
sure that your hands or feet do not get under the housing. Always
maintain a safe distance from the ejector opening.
Stop the motor, remove the spark plug connector, check that all moving
parts have come to a complete standstill and, if there is one, remove the
ignition key:
– when leaving the machine;
– before you check, clean or carry out any work on the machine;
– before you eliminate jams or blockages in the ejection channel;
– before you remove a foreign body;
– if the machine starts to vibrate strangely.
• If a foreign object has been encountered or if the machine becomes
blocked, e.g. by driving onto an obstacle, a specialist dealer must check whether
parts of the machine have been damaged or deformed. Any necessary repairs
must also be carried out by an authorized specialist workshop.
• If the machine starts to vibrate unusually heavily or to make unusual noises,
please have it checked immediately by an authorised workshop.
Heavy vibrations on your hands can damage your health. Please contact an
authorised workshop immediately if heavy vibrations occur.

• WARNING
The noise and vibration levels shown in these operating instructions are the
maximum levels for use of the machine.
The use of an unbalanced cutting element, the excessive speed of movement, or
the absence of maintenance have a significant influence on noise emissions and
vibrations. Consequently, it is necessary to take preventive steps to eliminate
possible damage due to high levels of noise and stress from vibration.
Maintain the machine well, wear ear protection devices, and take breaks while
working.
Adhere to the maintenance work listed in this operating manual and have the
equipment checked and serviced regularly by an authorised workshop.
Switch the mower blade off by releasing the bar of the blade stop. Make
sure that the cutting tool has come to s standstill:
– when driving outside the lawn on paths or streets;
– when you wish to adjust the cutting height;
– before you remove the grass collecting bag;
– before you remove the mulching plug.
• Stop the engine and make sure the ignition key (if present) has been removed:
– if you have to lift or tilt the mower e.g. for transport purposes;
– if you have to leave the machine for a short time;
– before you fill it with fuel. Only refill when the engine is cold!
• If the engine is equipped with a petrol shut-off valve, this should be closed
after mowing.
Maintenance and storage
• Insufficient equipment maintenance will lead to safety-related faults.
• Ensure that all screws have been tightened securely and that the machine
is in a safe working condition.
The ejection flap must only be opened and the grass collector or mulch
stopper removed when the cutting deck is switched off.
Never store a machine which still contains petrol inside a building where
petrol fumes may come into contact with naked flames or sparks or where
they may ignite.
The engine and exhaust reach very high temperatures during operation.
Allow the machine to cool down for at least 15 minutes before starting any
maintenance or cleaning work.
• To avoid a fire hazard, keep the engine, muffler (exhaust) and fuel tank free of
grass, leaves or escaping oil (grease).
When tilting the mower upwards or placing it on its side, make sure no oil or petrol
escapes. Fire hazard!
Allow the engine to cool down before you store the mower in closed rooms.
Do not store the mower near open flames or sources of fire such as boilers or
heating systems.
Before you start mowing, always check the grass collecting equipment for
wear or loss of functionality.
Before you start mowing, always check the condition and firm attachment
of the cutting blade. 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.
Changing, regrinding and balancing the cutting blade must be carried out
by an authorised professional workshop.
A wrongly assembled cutting blade coupling can allow the cutting blade
bar to get loose and cause severe injuries.
An improperly ground and imbalanced cutting blade can cause strong
vibrations and damage the lawn mower.
• For reasons of safety, always replace worn or damaged parts.
Protective gloves must be worn at all times during maintenance and
cleaning work.
Maintenance and cleaning work may only be carried out on level surfaces
with the engine switched off and the spark plug connector disconnected.
Regular maintenance is essential for safety and top performance.
• Never remove the spark plug connector when the motor is running! Risk: Electric
shock.
• Disconnect the spark plug connector only when the engine has cooled down.
Danger of burns!
