NOTE
Do not remove the free wheel pinion from the gear shaft!
–
Lubricate the wheel axle 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.
–
Set the disc in place, fix using the hexagon nut and tighten to such an extent that
the wheels can just about turn easily but without play.
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 be charged in the assembled or disassembled state.
–
Disconnect battery cable from cable harness.
–
Removing the battery
To remove the battery, unscrew the (TORX T30) screw, take off the cover and take
out the battery.
–
Connect the battery cable to the original charging device and plug the charging
device into a 230 V socket.
–
After charging the battery, refasten to the battery holder (if the battery was
dismounted for charging). Reconnect the battery cable to the cable harness prior
to mowing.

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
Check the oil level before every use and replenish oil if necessary (see "Check oil
level" and "Fill with oil", illustration Y1 ).
An oil change is not necessary. If you wish to change the oil, however, please follow the
instructions below.

Safety instruction!
See table for explanation of
In the case of unfavourable operation conditions (severe formation of dust), cleaning is
symbols page 3
required after every mowing process. Replace the paper filter element and pre-filter
annually or every 200 operation hours.
(Please see original spare parts and accessories for Order No. of filter element and pre-
filter)
Checking the spark plug (Illustration Y )
To check for wear, remove the spark plug connector (1) and unscrew the spark plug (2).
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 0.5 mm.
Screw the spark plug (pay attention to sealing ring) into the engine by hand and tighten
using the socket wrench. Press on spark plug connector. Replace the spark plug
annually.
Correct winter storage of the engine (or when not used for a long period
of time)

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 nut (1) on the air filter cover (2) and remove the cover.
Remove the pre-filter (3) and paper filter element (4).
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.
Clean the pre-filter every 50 operating hours.
Wash pre-filters in hot water with liquid detergent, rinse them out in clean water,
press out excess water and allow to dry thoroughly in air. Do not lubricate the pre-
filter with oil.
Insert the dry pre-filter on the paper filter element and fit both in the air filter plate
(5). Ensure that the air filter sits firmly in the plate.
Put the cover (2) on the air filter and fasten it with the nut (1) on the air filter plate
(5).
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.
