All models

11 SWITCHING OFF THE ENGINE (ILLUSTRATION F + A )

– Release the safety control bar (1) F .
– Close the fuel tap A (SA322020).

12 EMERGENCY STOPPING

Release the safety control lever and the drive switch bar.
– The mower will stop.
– The blade will stop.
– The engine will stop
NOTE
Before every mowing job, make sure that the safety control bar for the engine
brake and the engine drive control bar are working perfectly:
– when the safety control bar is released, the engine and cutter bar must come
to a standstill within three seconds.
– when the engine drive control bar is released, the machine must come to a
standstill immediately.
If this is not the case, please consult your nearest authorised workshop.

13 MOVEMENT DRIVE

Operating the rear wheel drive (Illustration G )

The rear wheel drive is switched on and off by means of the drive control handle (1) on
the top guide bar (2) when the motor is running:
– Pull and hold the drive control handle = mower moves
– Release the drive control handle = mower stops (0-position).
The drive control handle must always be pulled firmly up against the top bar. Improper
activation will cause wear on the gearbox.
NOTE
The rear wheels click when the mower is pushed forwards.

Adjusting the speed (Illustration H )

IMPORTANT
The speed may only be adjusted when the engine is running in order to avoid
damage!
The driving speed is set using the rotary knob mounted on the left.
– The knob can be turned in both directions for speed adjustment, so that the
required driving speed can be set. The arrow on the knob indicates the driving
speed.
– Position "Hare" = fast (max. speed)
– Position "Tortoise" = slow (min. speed)
NOTE
Mowing at high speed leads to poor cutting pattern or collection result. Always
adapt the speed to the prevailing conditions. For longer grass sections, a slower
driving speed should be selected.

14 MOWING

Mowing on slopes

SA322020
NOTE
The mower can be used on banks and slopes with a gradient of up to 48% (26°
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.
Manually guided lawnmowers should never be used for slopes with a gradient in
excess of 26% (15° angle of slope). Stability may be lost!

NOTE
The mower can be used on banks and slopes with a gradient of up to 46% (25°

All models

Checking the oil level

Check oil level each time prior to mowing Y1 . Never let the engine to run with too little
or too much oil. Irreparable damages could occur.

Checking operating safety

The lawnmower is equipped with a motor stop device.
Before every mowing job, make sure that the motor stop safety control bar is
working perfectly. When the control bar is released, the motor and 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 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 also be checked before every
mowing job. 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 blade coupling 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

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

What is understood by the term mulching?

When mulching, the lawn is cut and the cut blades of grass are then, immediately
thereafter, chopped several times to become even smaller using the special mulch
blade. This mulch blade straightens the grass blades and cuts the blades into very short
segments which are then distributed evenly over the lawn surface.
The grass blade segments can now dry and rot more quickly, thus facilitating the
production of humus. This enables natural fertilisation of the soil and also protects
against dehydration.
Gathering and removal of cuttings is no longer necessary. The mulch concept is thus
environmentally-friendly and stimulates the ecology.
