16 CARE AND SERVICING OF YOUR LAWNMOWER

Regular care is the best way to guarantee a long service life and problem-free
operation. Insufficient equipment maintenance will lead to safety-related faults!
Only use original spare parts because only those guarantee safety and quality!

Cleaning (Illustration A + O )

IMPORTANT
During cleaning and maintenance work, always close the fuel tap and the
ventilation valve (1) A , do not place the mower on its side, tilt it forwards instead
O (spark plug facing upwards) as otherwise start-up difficulties could occur.
Secure the mower in its raised position!
NOTE
When tilting the mower upwards, make sure no oil or petrol escapes. Fire hazard!
Remove dirt and residual grass directly after mowing. Use a brush or cloth for cleaning.
Do not rotate the cutter bar, as otherwise motor oil is pumped into the carburettor/air
filter and start-up difficulties can occur.
CAUTION
The deflector is under tension, be careful when cleaning it as otherwise fingers
can become crushed.
IMPORTANT
Never use high-pressure cleaners or a normal water jet to clean
the drive area, engine parts (such as ignition system, carburettor
etc.), seals and bearing points. Damage or expensive repairs can
be the consequence of such action.

Storage

Always keep the machine in a clean condition in a closed, dry room out of reach of
children. Always allow the engine to cool down before you store the machine in a
closed room.

Collapsing the handle (Illustration B4 )

– To save storage space or for transport, loosen the two handle nuts such that the
top guide tube can be folded down towards the engine.
– Do not kink nor squeeze the throttle cables in the process.
CAUTION
When folding the bar for transport and storage, the bar may fold over
unintentionally when the grip nuts are released. In addition, beware of potential
crushing spots between the bottom and top parts of the bar. This may result in
risk of injury!
IMPORTANT
Make sure that the cables are not pinched, squeezed, twisted or overstretched
when the handlebars are folded apart or collapsed! Always run the cables along
the outside of the bar connection. A damaged cable may result in a technical
defect of the equipment.

Transporting and securing the equipment (Illustration N + N4 )

– If the equipment must be carried, hold it at the front of the housing (1) and at the
rear by the cross bar of the guide bar, or if the bar is folded, by the cross bar of the
lower guide bar section (2) (see illustration N ).
Please take the weight of the machine into consideration before lifting it (see
Technical Data). Lifting large weights can result in health problems.
We recommend that this equipment should always be lifted or carried by at least
two people, when other means of help are not available.
When this equipment is transported on a load area, a loading ramp should be used for
loading and unloading.
NOTE
Avoid injuries! Be especially careful when loading or unloading the equipment.
When a trailer is used, we recommend ensuring that it is equipped with stable
sidewalls.
Only the marked points on the transport vehicle may be used to secure the
equipment.
– Transport the unit upright on all 4 wheels to avoid fuel loss, damage to the
equipment and personal injury.
Safety instruction!
See table for explanation of symbols
page 3
– Park the means of transport on level ground so that the equipment cannot roll
away before it is secured.
– Secure the equipment with approved load-securing devices (e.g. tie-down straps
with clamping elements) on or inside the vehicle. Tie-down straps are belt bands
made of synthetic fibres. Every tie-down strap is marked with a label. The label
contains important details for application. The information on this label must be
heeded when using the tie-down strap.
– For loaded goods that can roll, we recommend using direct strapping with four
lashing straps. For this purpose, the belts are fastened directly on the fastening
points on the equipment (see illustration N4 ) and in the tie-down strapping points
on the loading surface and slightly pre-tensioned.
NOTE
Do not tighten the belts too firmly. Fixing the equipment too firmly can cause
damage.

Maintenance of the blade

A sharp blade guarantees optimum cutting performance. Before you start mowing,
always check the condition and firm attachment of the cutting blade. 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.

Sharpening and balancing the blade (Illustration Q )

WARNING
The sharpening and balancing of the blade should be carried out only by an
authorized specialist workshop. An improperly sharpened or unbalanced blade
can cause severe vibrations, and damage the lawnmower.
The cutting edges of the cutting blade may be grinded only until the respective value
(see illustration Q ) or the marking (1) on the cutting blade (ring) has been reached.
Attention! Observe the grinding angle of 30°.
Your professional workshop can check this value - (grinding limit) for you!
WARNING
A blade by which the wear limit (marking) has been exceeded can break off and
spin away; this can cause severe injuries.

Replacing the blade

WARNING
The cutting blade bar must always be replaced by an authorised workshop. A
wrongly assembled cutting blade coupling or a blade screw that is tightened too
tightly or too loosely can allow the cutting blade bar to become loose and cause
severe injuries.
– Only use genuine cutter bars for replacement. Non-equivalent spare parts can
damage the machine and are a safety hazard.
– Replacement cutting tool must be marked permanently with the name and/or
company logo of the manufacturer or supplier and the part number.

Servicing the front wheels

The wheels are equipped with maintenance-free bearings. Maintenance is not required.

Servicing the rear wheel drive (Illustration R )

Lubricate the wheel bearings every 50 operating hours.
– Pull the drive wheels off after loosening the nuts and removing the dust cap from
the wheel axle.
– 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 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 dust cap 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.
