ATTENTION
Ensure before every mowing job that the safety control bar engine stop and the
autodrive control bar work properly:
–
When the safety control bar is released, engine and cutter bar must come to
a standstill within three seconds.
-
When the autodrive control bar is released, the machine must come to an
immediate standstill.
If this is not the case, please consult your nearest authorised workshop.

The rear wheel drive is switched on and off using the drive control bar (1) on the upper
guide bar (2) while the engine is running:
–
Pull and hold the drive control bar = mower moves.
-
Release the drive control bar = mower stops (0 position).
The drive control bar must always be firmly pulled towards the top bar. Inappropriate
actuation leads to wear of the transmission.
NOTE
The rear wheels click when the mower is pushed forward while the engine is not
running.

The travel speed is adjusted with the rotary knob on the left.
–
For speed adjustment, turn the knob in both directions to set the desired travel
speed. The arrow on the rotary knob indicates the travel speed.
–
“Hare” position = fast (max. speed).
–
“Turtle” = slow (min. speed).
NOTE
Excessive mowing speed leads to an unclean cut pattern or collection result.
Always adjust the speed to the individual circumstances. For cutting of longer
grass, a lower travel speed should be selected.

ATTENTION
The mower can be used on banks and slopes with a gradient of up to 46%
(25° angle). Any steeper slopes can lead to engine damage.
For safety reasons, however, we urgently recommend you do not exploit this
theoretical performance potential. Always make sure you have a firm stance.
Walk-behind lawn mowers should never be used for slopes with a gradient in
excess of 26% (15° angle of slope). Stability may be lost!

The lawn mower is fitted with an engine stop device.
Before every mowing job, make sure that the engine stop safety control bar is
working perfectly. When the control bar is released, engine and cutter bar must come to
a standstill within three seconds.
After release, the bar must always return to the position shown in the
“Description of components” diagram.
If this is not the case, it must be checked immediately by an authorised workshop.
Risk of injury!
If the stopping time of the blade is longer, stop using the device and take it to an
authorised workshop.
Measuring the stopping time
After starting the combustion engine, the blade rotates and a wind noise can be heard.
The stopping time corresponds to the duration of the wind noise after the combustion
engine has been switched off; it can be measured with a stopwatch.
Machine safety and protective devices must not be manipulated or disabled.
The correct operation of the autodrive control bar must also be checked before each
mowing job. When the autodrive control bar is released, the machine must come to an
immediate standstill. 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 any risk, always check the condition and firm seating of the blade before
each mowing job. The blade fastening screw must always be tightened by an
authorised workshop. If the blade screw is tightened excessively or insufficiently,
blade coupling and cutter bar may be damaged or get loose, which can lead to serious
injuries. A worn or damaged blade must imperatively be replaced. (See chapter
“Maintenance of the cutter bar”).
Check the blade coupling for wear and a tight fit every 10 operating hours. Also check
device screws and nuts for a firm fit and re-tighten, if necessary.
Make sure the spark plug connector is fitted tightly. Risk of electric shock.
Never remove the plug connector with the engine running. Risk of electric shock.
Only remove the plug connector if the engine has cooled down. Risk of burns.
If the mower 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.

In Germany, the time for the operation of lawn mowers is regulated in the “32nd
Ordinance for the Implementation of the Federal Immissions Act (32nd BimSch-
V)”.
In addition, regional restrictions are possible (e.g. to observe the afternoon quiet hours);
related information is available from the competent municipal authority.

WARNING
Remove all foreign bodies (stones, wood, branches, etc.) from the lawn before
any mowing; however, you should still keep an eye out for objects lying around
while mowing.
You can get an introduction to lawn care from your dealer on request. Information and
instructions for mowing can also be found on the manufacturer's website.
