9.2 Lubricating plan
To ensure that moving parts can move freely, we
recommend lubricating the following points at
least once a year.
Use a cloth to clean all points to be lubricated be-
fore greasing or spraying. Do not use water, so
as to avoid possible corrosion.
Lubrication points:
■
Grease the grease nipples on the right and
left steering knuckles (21) using multi-pur-
pose grease.
■
Spray oil onto the bearings of the front axle
on the frame (21/1).
■
Grease the toothed segments and steering
pinion on the steering box (22) using multi-
purpose grease.
■
Grease the roller bearings and hub on the
front and rear axles (23 / 20) with multi-pur-
pose grease.
NOTE The front and rear wheels must be re-
moved for greasing the axles and bearings.
■
Pivoting and bearing points: Lubricate all
movable pivoting and bearing points.
9.3 Wheel change
Wheel changes are only allowed to be carried out
on firm, level ground.
1. Park the lawn tractor and remove the ignition
key.
2. Press the brake pedal (05/1) fully and lock it
using the locking lever (05/2).
3. Secure the lawn tractor with chocks to pre-
vent it from rolling away. Place the chocks
under the side that is not being raised.
4. Use suitable lifting gear (e.g. a scissor jack)
to lift the lawn tractor on the side where the
wheel should be changed. Lift the tractor until
the wheel to be changed can turn freely.
Important! Danger of damage to the de-
vice!
Take care not to bend any tractor elements
when lifting. Only position the jack on sturdy
metal components.
5. Secure the lawn tractor by placing a sturdy
support (e.g. a wooden block) under a sup-
porting part of the chassis so that it cannot
drop down even if the jack were to slip or tip
over.
6. Pull off the protective cap (19/1).
7. Use a screwdriver to press out the lock wash-
er (19/2). Make sure not to lose the parts.

8. Pull off the plain washer (19/3).
9. Pull the wheel off the axle.
Note: Do not lose the feather key when pull-
ing the rear wheels off the axle!
10. Clean the axle and the hole in the wheel be-
fore reassembly, and grease both of them
with multi-purpose grease.
11. Put the wheel onto the axle.
Note: When pushing on the rear wheels,
make sure that the grooves for the feather
key and the rear wheel are aligned so that
the feather key can be pushed in without
force.
12. Put the washer onto the axle.
13. Push the lock washer into the groove on the
axle. If you use a pair of pliers to do this, take
care not to damage the axle using the pliers.
14. Put the protective cap onto the axle.
15. Remove the securing support and use the
jack to lower the tractor carefully down to the
ground.
9.4 Starter battery
No charger is supplied for the starter battery of
the lawn tractor.
Precise battery designation: see battery box. The
starter battery is located under the engine cover.
The starter battery is always supplied from the
factory pre-charged.
Safety instructions
WARNING! Danger if the starter battery
is not handled correctly! The following points
must be complied with to avoid the dangers aris-
ing from incorrect handling of the battery!
■
Do not store the starter battery in the immedi-
ate vicinity of naked flames, do not burn it or
place it on heaters. Risk of explosion.
■
Store the starter battery in a cool, dry room
(10 - 15 °C) over the winter. Avoid storing at
temperatures below the freezing point.
■
Do not leave the starter battery without
charge for a long period. If the starter battery
is not used for a long period, it should be
charged using a suitable charger.
■
Do not smash the starter battery. The electro-
lyte (sulphuric acid) causes chemical burns to
the skin and clothing – immediately rinse
away with plenty of water.
■
Keep the starter battery clean. Only wipe
clean with a dry cloth. Do not use water, pet-
rol, thinners or similar for this purpose.
