19 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, always close the fuel tap 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 or placing the mower on its side, ensure that no oil or fuel comes out
of the machine. Fire hazard!
Remove dirt and grass residue immediately after finishing mowing. Use a brush or cloth
to clean.
NOTE
Do not put your fingers into the openings of the fan housing and hold onto the
fan. If the blade bar is rotated during cleaning, there is a risk that your fingers
may become caught between the fan and the fan housing!
IMPORTANT
Never use a pressure cleaner or ordinary water jet to clean the drive section,
motor parts (like ignition system, carburettor etc.), and bearings. Damages or
expensive repairs can be the consequence of such action.
IMPORTANT
If the underside of the mower is accidentally cleaned with water, immediately
start the motor again and turn on the blades. Any remaining water may damage
the components (e.g. ball bearings), thus allow the coupling to operate for
several minutes to ensure that the water is thrown out of the components.

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 / handle 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 the holes
in the housing.
– Do not kink nor squeeze the throttle cables in the process.
47-K VARIO B, R47KB
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.
54-K VARIO B, JX90
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 handle
nuts and snapping of the locking cams out of the holes in the bar connection. In
addition, crushing spots can occur between the base and top of the bar and the
bar connection/housing. This may result in risk of injury.

Transporting and securing the equipment (Illustration N )

47-K VARIO B, R47KB
– 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 ).
54-K VARIO B, JX90
– If the equipment has to be carried, do not hold the ejection flap! Only hold the
carrying handle at the front and the bar ends at the back N . Please do not lift the

part of the bar that is folded forward. There is a risk of injury at the ends of the
bars.
All models
– 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 equipment in an upright position.
– 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.
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 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
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

Lubricate the wheel bearings once a year or every 15-20 operating hours.
47-K VARIO B, R47KB
– Remove the wheel cap cover on both sides.
– 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.
– After the bearings have been lubricated using the roller bearing grease "KAJO-
Longlife grease LZR 2", push the wheels back on. First insert the collar washer into
the wheel, 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.
