Servicing the rear wheel 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
–
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.

In the case of unfavourable conditions (heavy dust development), the mower must be
cleaned every time it is used, otherwise after 25 operating hours or every year.
(Please see original spare parts and accessories for order no. of filter element)
Checking the spark plug (Illustration Y )
To check for wear, remove the spark plug connector and unscrew the spark plug. If the
electrode is badly worn the spark plug must be replaced as a matter of course. (Order
no. see original spare parts list and accessories).
Otherwise it is sufficient to clean the spark plug and set the electrode gap to 0.7-0.8
Safety instruction!

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.
Open the cover (1), pull down and out and remove.
Remove the filter element (2) carefully and knock gently onto a smooth surface if
soiled. Replace if heavily soiled or damaged.
Never lubricate the insert with oil or blow it with compressed air. Severely dirty or
oily filter elements must be replaced.
After cleaning or replacement, insert the filter element into the air filter plate.
Insert the hooks (3) on the cover (1) into the seat (4) at the bottom in the air filter
plate.
Tilt the cover upwards and close with care.
Empty the petrol tank or allow the engine to run until it stops due to lack of fuel.
Switch off engine and disconnect spark plug cable.
Drain off the oil while the engine is still warm. Fill with fresh oil (for quantity and
type, see technical data).
Clean grass and chaff from cylinder and cylinder head fins and around muffler.
Always keep the machine in a clean condition in a closed, dry room out of reach of
children.
