Maintenance and care

8.2 Wheel axles and wheel hubs

Fig. 8
Wheel axles and wheel hubs are to be lubricated
occasionally (at least once a year). Remove wheel
cap, release screw and remove wheel. During
disassembly observe the sequence for the
reassembly of the parts.
Maintenance of the rear wheel-self-propelled drive
roller:
Fig. 9
• After removing wheel caps and loosening
fastening screws, remove drive wheels.
• Remove grass debris and dirt from all drive
wheel areas.
Attention: Do not remove neutral gear pinions
from the gear shaft; however, check if they turn
slightly counter-clockwise to the drive direction.
• Lightly lubricate the two pinions (free wheel and
plastic pinion) with water-repellent grease which
is compatible with plastic.
• Fill the space inside the drive wheel between
both taper bearings with the same or a
compatible grease.
• Also lubricate the wheel axles with grease.
• When refitting the drive wheel, ensure that both
pinions engage with each other; slightly turn the
wheel on its axle, if required.

8.3 Drive belt

Tensioning the drive belt
Fig. 10
Remove the lid from the battery/gearbox chamber
(15) after releasing both screws. Undo the fixing
screw (C) of the tensioning lever. Tension the drive
belt by moving the tensioning lever (in the direction
of the arrow).
Note: Check the belt tension every 20 hours or at
least once per mowing season.
The belt is correctly tensioned of the centre can be
deflected by approx. its own thickness.
Changing the drive belt
• Position the lawn mower on its handle and
discharge deflector (Fig. 7). First pull the spark
plug cap and ensure that the fuel tank is empty.
• First remove the blade and impeller, then the
old drive belt.
• Position the new drive belt from below onto belt
pulley A and insert to the rear into the mower
chassis.
• Reposition the mower on its wheels.
• Position the drive belt onto pulley B on the
gearbox side.
• Tighten V-belt as described above.
• Screw on cap tightly.
• Assemble blower wheel and blade. Observe
sequence of assembly parts and observe the
blade's torque. (Fig. 12).

8.4 Oil level check

Attention: The engine oil affects the lawn mower's
efficiency and life span. Never operate the engine
without oil or with little oil. Major engine damage
can occur. The optimum viscosity depends on
where the lawn mower is used (air temperature
and altitude) and can be found in the engine
owners manual.
