Cutting blade maintenance
Make sure that the cutting blade remains sharp for
the entire mowing season to avoid shredding or
tearing the blades of grass. Shredded grass blades
turn brown on the edges. This reduces their growth
and leaves the lawn prone to diseases.
■
Check the cutting blade for sharpness and
signs of wear or damage after each use! If
necessary please contact a service work-
shop.
■
If replacement is required, only use original
manufacturer replacement blades.
7 CLEANING THE LAWN TRACTOR
The lawn tractor must be cleaned regularly to en-
sure optimum function and a long service life.
Clean the lawn tractor after each use to remove
adhering dirt and detritus.
Use preferably compressed air and a brush for
cleaning. The water jet from a high-pressure
cleaner or a garden hose can damage the electri-
cal system or bearings.
In particular, ensure that the engine, transmission
and deflection pulleys, as well as the entire elec-
trical system do not come into contact with water.
WARNING! Dangers when cleaning!
During all cleaning work:
■
Switch off the engine and remove the ignition
key.
■
Remove the spark plug connector.
■
Protective devices removed for cleaning must
be reinstalled afterwards.
■
DANGER OF BURNS: Do not clean the lawn
tractor until it has cooled down. The engine,
transmission and silencer get very hot!
■
DANGER OF LACERATIONS: When working
on the cutters, pay attention to the sharp
blades. In mowers with more than one blade,
moving one cutter can cause the other to
move as well!
7.1
Cleaning the grass catcher
To do this, remove the grass catcher and clean it
by spraying inside and out with a water hose.
Firmly adhering contamination must be scraped
off carefully, such as by using a brush. Especially
in grass catchers with a fabric covering, take care
not to damage the fabric.
NOTE Empty the grass catcher before
cleaning as described. A full grass catcher is too
heavy to be removed safely.

Removing a grass catcher
1. Switch off the engine.
2. Tilt the grass catcher slightly.
3. Remove the grass catcher upwards.
Removing an electrically operated grass
catcher
1. Switch off the engine.
2. Make sure that the electrically operated grass
catcher is closed.
3. Tilt the grass catcher (approx. 30°).
4. Remove the grass catcher upwards.
7.2
Cleaning the deck, engine and
transmission
IMPORTANT! Damage to the electrical sys-
tem by penetrating water! Use preferably com-
pressed air and a brush for cleaning.
Do not use water or a high-pressure cleaner to
spray down the engine or any of the bearing
points (wheels, transmission, blade bearing).
Water penetrating the ignition system, carburettor
and air filter can cause malfunctions. Water in the
bearing points can lead to loss of lubrication, and
thus cause irreparable damage to the bearings.
Use a cloth, hand brush, long-handled paintbrush
or similar for removing dirt and grass residues.
7.3
Cleaning the discharge channel (18)
Regular cleaning ensures the smooth operation
of the cutting height adjustment mechanism.
The discharge channel consists of two parts
pushed one inside the other. The lower part is
firmly engaged in the lower deck. The upper part
can be pulled out for cleaning.
1. Remove the grass catcher.
2. Remove the screws (18/1) on the left and
right of the discharge channel (18/2).
3. Pull the discharge channel through the back
wall and out to the rear.
4. Thoroughly clean the upper and lower dis-
charge channel.
5. Insert the discharge channel into the back
wall. When doing this, make sure that the up-
per and lower parts fit cleanly one inside the
other.
6. Screw it on tight using the two fastening
screws.
7. Mount the grass catcher.
