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 O )
IMPORTANT
During cleaning and maintenance work, do not place the mower on its
side, tilt it forwards (spark plug facing upwards) as otherwise start-up
difficulties could occur. When tilting the mower upwards make sure the
ejection flap does not get damaged. 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.
NOTE
Do not insert your fingers into the openings in the fan housing and hold
the fan. If the cutter bar should be 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, 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 A1 )
– For space-saving storage space or for transportation, open the quick
releases, loosen the wing nuts such that the handlebar can be folded
together without resistance in Z-shape above the engine A1 .
The locking cams on the lower end of the bar have to snap out of
–
CAUTION
When the bar is moved for transport and storage purposes, the bar may fold over
unintentionally during opening of the quick releases, loosening of the wing nuts
and snapping of the locking cams out of the holes in the housing. In addition,
crushing spots can occur between the base and top of the bar and the housing.
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

Do not tighten the belts too firmly. Fixing the equipment too firmly can cause damage.
Maintenance of the blade
Safety instruction!
See table for explanation of
A sharp blade guarantees optimum cutting performance. Before you start mowing, always check
symbols page 3
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.

Servicing the wheels
Lubricate the wheel bearings once a year or every 15-20 operating hours.

the holes in the housing.
Do not kink nor squeeze the throttle cables in the process.
If the equipment has to be carried, do not hold the ejection flap! Hold the carrying handle at
the front and 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 two people should always lift or carry the equipment.
Transport the unit upright on all 4 wheels to avoid fuel loss, damage to the
equipment and personal injury.
Park the means of transport on level ground so that the equipment cannot roll away
before it is secured.
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. Secure the wheels of the equipment in such a way that it does not move during
transportation.
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.
Remove the covers in the middle of the wheel caps.
Use a socket wrench to loosen the hexagon nut, remove the washer, pull the wheels off
the wheel axle together with the wheel cap and collar washer. Remove the wheel cap from
the wheel.
