NOTE
Set bot levers to the same height except for the two lowest cutting height
settings. For the two lowest cutting heights, set the rear lever one notch higher
than the front lever.
This setting provides optimum discharge of the cut material during mulching.
Start with a higher setting and then adjust this downwards if necessary in order
to avoid the lawn being cut too short.
IMPORTANT
Mowing at the lowest cutting height should only be carried out on level and flat
lawns.
Please note that the lower cutting height settings may only be used for optimal
conditions. If you select cutting height that is too low, the turf may be damaged
and under certain circumstances even destroyed.
Besides the cutting height, the driving speed also influences the cutting pattern.
Adapt the cutting height and driving speed to the grass height to be cut, the
motor drive may not need to be switched on.
Adjusting handle height (Illustration W3 )
NOTE
Three different handlebar heights can be set.
Loosen the handle nuts until the bar can be moved freely. Do not loosen them too far so
that the screws do not come out of the square in the bar.
1. Take hold of the rod of the bracket and the bottom part of the bar and push them
forwards together until the screws are released from the catch.
2. Move the bar forwards or backwards until the required position has been found.
3. Take hold of the bracket by the rod and pull backwards with the bar until the
screws lock into the new position.
Tighten the handle nuts again. Use the same position in the bracket on both sides.
IMPORTANT
When adjusting the handlebar height using the bracket only loosen the handle
nuts to such an extent that the bar can be moved freely during this work.
This prevents the bar folding over unintentionally and avoids crushing spots
between the bottom part of the bar and the housing.
9 BEFORE USING THE LAWNMOWER FOR THE FIRST TIME
Check all screw connections and the spark plug connector for a tight fit. Tighten the
screws if necessary! Attachment of the cutter bar must be checked in particular (refer
here to the chapter "Cutter bar care").
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.
The lawn mower is equipped with a motor stop device.
Before using the equipment for the first time, 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!
Make sure that all protective devices have been attached properly and are not
damaged.
Filling with oil (Illustration Y1 )
IMPORTANT
Avoid damage! Engine is delivered without oil. You must add oil before running
the engine.
Before starting the engine for the first time, use a funnel to fill motor oil (quantity and
quality see technical data) having unscrewed the dipstick in this opening first.
– Set the mower on level ground.

– Slowly fill oil through the filler neck. Do not overfill.
Insert the dipstick and screw it tight.
SA322020
– Check oil level
Remove the dipstick. Use a clean cloth to wipe off the dipstick, then insert it again
but do not screw tightly. Then pull the dipstick out again and read off the oil level.
The oil must be between the "L" and "H" marks. Replenish oil if necessary.
However, the oil must not be higher than the "H" mark on the dipstick. Overfilling
will lead to engine damage.
Insert the dipstick again and tighten.
SA322120
– Check oil level
After filling the oil, wait for about one minute and then check the oil level.
Remove the dipstick. Use a clean cloth to wipe off the dipstick, then insert it again
and screw tightly. Then pull the dipstick out again and read off the oil level. The oil
must be at the full mark at the top (arrow). Replenish oil if necessary. The oil level
must not be higher than the full mark, however.
Insert the dipstick again and tighten.
All models
– After initial filling, remove the "NO OIL" sign from the top of the engine.
Filling with fuel
– Only fill the tank with fresh and clean unleaded standard petrol. Never use
alkylate-based petrol.
Fuel with up to 10% ethanol or 15% MTBE content is acceptable.
Never use petrol with an ethanol content greater than 10% or an MTBE content
greater than 15% since this can lead to damage to the engine or fuel system.
– Fuel tap (SA322020) should be closed A !
– Unscrew the fuel cap.
– Use a funnel to fill the fuel up to the max. lower edge of the filling nozzle.
– Replace the fuel filler cap and screw tight.
10 STARTING THE ENGINE (ILLUSTRATION A + D + E )
Only start the engine when you are standing behind the mower.
Always place the mower on a level area which is not covered with high grass (if the
grass is too high it will block the cutter bar start-up and make starting the mower more
difficult). When the engine is started, 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.
CAUTION
Hold the starter cable handle firmly when starting. The handle may otherwise slip
out of your hand. Risk of injury!
IMPORTANT
The motor only operates when the safety control bracket is pressed against the
upper part of the handlebar. As soon as the safety control bracket is released,
this returns to its original position under spring force, the motor brake is
actuated, and the motor and blade come to stop within three seconds.
SA322020
– Open the fuel tap (1) A .
– Push and hold the safety control bar (2) on the top tube (3) D .
– Slowly pull the starter cable (4) out until resistance can be clearly felt.
Now return the handle to its initial position and then rapidly pull it out E – the
engine begins to run, slowly rewind the cable.
SA322120
– Push and hold the safety control bar (2) on the top tube (3) D .
– Slowly pull the starter cable (4) until resistance is felt, then rapidly pull it out E –
the engine begins to run, slowly recoil the cable.
NOTE
This engine has a ReadyStart system: This system has a temperature-controlled
®
automatic choke. The engine runs with optimum power at maximum speed, which is
required for a clean cutting pattern (engine speed = blade speed).
