17 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 , tilt the mower forwards O (spark plug facing upwards). If
it should become necessary to place the mower on its side, then place it on the
exhaust side, never on the carburetor side, as otherwise start-up problems could
occur.
When tilting the mower forwards make sure the ejection flap does not get
damaged. Secure the mower in its raised position!
NOTE
When tilting the mower upwards or placing it on its side, make sure no oil or
Fire hazard!
petrol escapes.
NOTE
Do not insert your fingers into the openings in the fan housing and hold the fan.
If the cutter bar is turned during cleaning, there is a risk of fingers being
squashed between fan and fan housing.
IMPORTANT
Never use high-pressure cleaners or a normal water jet to clean the drive area,
engine parts (such as ignition system, carburetor etc.), seals and bearing points.
Damage or expensive repairs can be the consequence of such action.
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.

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 )

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.
Safety instruction!
See table for explanation of symbols
page 3
– 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!

Transporting and securing the equipment (Illustration N + N4 )

– In case the equipment has to be carried, hold it on the carrying handle at the front
(1) and on the cross tube of the top part of the guide bar (2) at the back (see
Figure 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 at disposal.
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.
– Park the means of transport on level ground so that the equipment cannot roll
away before it is secured.
– Transport the unit upright on all 4 wheels to avoid fuel loss, damage to the
equipment and personal injury.
– Remove the collecting bag and secure it separately during transport
– 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 Figure 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.
CAUTION
When moving the bar for transport and storage purposes, the bar may fold over
unintentionally during loosening of the hexagon nuts (5) C1 (only loosen them
to such an extent that the bar can move freely) and the attachment screws (1)
C1 between the base of the bar and the bar connection point. In addition,
beware of potential squashing spots between the base of the bar and the bar
connection point/housing. This may result in risk of injury!

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 blade must only be ground down to the mark (1) (see
illustration Q ) on the blade (ring). Warning! Keep to a 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
