– After the bearings have been lubricated using the roller bearing grease (e.g.
"KAJO-Langzeitfett LZR 2"), push the wheels back on. First insert the collar
washer into the wheel, set the wheel cap in place and press until you hear it click.
Set the washer in place, fix using the hexagon nut and tighten to such an extent
that the wheels can just about turn easily but without play. Replace the covers in
the middle of the wheel caps.
Servicing the rear wheel drive (only with selective
engine drive) (Illustration R )
Lubricate the wheel bearings once a year or every 15-20 operating hours.
– Remove the wheel cap cover on both sides.
– Use a socket wrench to loosen the hexagon nut, remove the washer, pull
the drive wheels off the wheel axle together with the wheel cap and collar
washer.
– Remove the wheel cover, pay attention to the thrust washer.
– Remove any soiling from the wheel cover, the free-wheeling pinion
on the gear shaft and the gear rim on the inside of the wheel.
NOTE
Do not remove the free wheel pinion from the gear shaft!
– Lubricate the bearings using the roller bearing grease "KAJO-Longlife
grease LZR 2". Do not lubricate the free-wheeling pinion and gear rim in
the wheel!
– Set the wheel cover in place and push the start-up disc onto the wheel
axle. When putting the drive wheel in place make sure the pinion and
gear rim interlock, turn the wheel on the axle slightly to achieve this if
necessary.
– If the wheel cap has loosened from the wheel, insert the collar washer
into the wheel first as shown in Figure R , set the wheel cap in place
and press until you hear it click. Set the washer in place, fix using the
hexagon nut and tighten to such an extent that the wheels can just about
turn easily but without play. Replace the wheel cap covers.
Servicing the drive (only with selective engine drive)
– It is absolutely essential that the Bowden cable runs easily for switching
on and off, so that the control drive works perfectly.
– The Bowden traction mechanism has been set ready for operation at
the works and requires no adjustment.
Changing the drive V-belt
The drive V-belt must be replaced by a specialist workshop.
Recharging the starter battery (only for electro-start)
IMPORTANT
Use the charger supplied only for charging the respective mower
battery. Equally, do not try to charge your mower using a different
charger. You could endanger yourself or damage your equipment.
For safety reasons and to avoid damage to the charger, it may only be
used indoors and in dry rooms and the battery must not be charged in
direct sunlight.
The battery can either be charged in the installed position or removed for
charging.
– Separate the connection between the battery cable and the wiring
harness.
– Remove the battery.
To remove the battery, detach the cable from the wiring harness, remove
the wing nuts. Turn the battery with the battery lid by 90° to the front and
remove upwards.
– Connect the battery cable to the original charger and plug the charger into
a socket with 230 V. (See also Chapter "Prior to initial start up – Charging
the starter battery")
– After charging the battery, secure it to the battery holder again (if it was
removed for charging). Connect the battery cable back to the wiring
harness before you start mowing. (See also Chapter "Preparatory work –
Mounting the charged starter battery")
18 SERVICING THE ENGINE
WARNING
Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause
serious illness or death.
Do not run an engine in an enclosed area, such as a garage, even with doors and
windows open.
Move the machine to an outside area before starting the engine.
IMPORTANT
To clean the engine and for maintenance work, do not place the engine or mower
on its side but tilt forwards O (spark plug upwards) because otherwise there may
be problems starting the engine. When tipping the mower forwards, make sure
that the ejection flap is not damaged. Secure the mower in the raised position!
ATTENTION
When tilting the machine upwards, ensure that no oil or fuel comes out of the
machine. Fire hazard!
The regular implementation of the prescribed maintenance and care work are the prerequisite
for a permanent and fault-free functionality of the motor and also the basic requirement for any
guarantee claims.
The motor should be kept clean, particularly on the outside, and the silencer and cylinder area
must always be kept free from foreign bodies (e.g. grass residue). The exhaust and motor
reach very high temperatures when in use. Flammable foreign bodies such as foliage, grass
etc. may catch fire.
Perfect cooling can also only ensured when cylinder ribs are always clean.
IMPORTANT
Never use a pressure cleaner or ordinary water jet to clean the motor. Damages or
expensive repairs can be the consequence of such action.
Oil change
NOTE
For environmental reasons, we recommend that the oil change is performed by an
authorised workshop.
The first oil change in a new engine is required after approx. 5 operating hours. Later, it should
be done every 50 operating hours or at least once per mowing season.

Before the engine or the equipment is tilted to drain oil, empty the petrol tank and let the
engine to run until it stops due to lack of fuel.
Stop the engine and remove the spark plug connector.
Renew the oil as long as the engine is warm.
To change the oil, remove the dipstick from the oil refill neck.
Turn the mower on one side so that the spark plug side is facing upwards and the used oil
can drain into a container.
Do not drain used oil into the sewage system or soil; dispose of it according to the
local regulations.
Position the mower straight and fill brand-name oil into the spout (for quantity and quality,
see technical data). Screw the dipstick in and check the oil level (see "Check oil level" and
"Fill with oil", illustration Y1 )! If the oil level is correct, insert the dipstick and tighten it.
Loosen the latch taps of the air filter cover (4) from the air filter housing (1) with a
screwdriver and remove the air filter cover (3).
Remove the air filter (2).
Clean the paper filter element every 50 operating hours.
Knock gently onto a smooth surface if soiled lightly. Replace if heavily soiled or damaged.
Do not wash out paper filters, nor blow them out with compressed air or grease them.
