nance must be carried out on a stationary machine
when the engine is not running.
Prevent the machine from rolling by al-
ways applying the parking brake.
Prevent unintentional starting of the
engine by always stopping the engine,
disconnecting the spark plug cable
from the spark plug and earthing it.
Disconnect the negative cable from the
battery.
MAINTENANCE TIPS
To make cleaning and maintenance easier, the cut-
ting deck can be folded up:
1. Set the cutting height setting to an intermediate
position (= drive belt minimum tension).
2. Hook the belt idler arm on the mount (fig. 7)
3. Force the belt off the centre pulley F.
4. Undo both pins (fig. 6).
5. Grip the deck's frame.
6. Fold up the deck until it is upright on the rear
support plates (fig. 8).
CLEANING
After each use, the underside of the cutting deck
should be rinsed off.
If the grass has dried solid, scrape clean the under-
side.
If necessary, touch up the underside with paint to
prevent corrosion.
POSITIVE DRIVE BELTS
If one of the blades has struck a solid object (e.g. a
stone), the belt tension may be altered. This can
lead to the positive drive belt 'over-meshing'
which, in the long term, can damage the blades.
When replacing positive drive belts, en-
sure that both the outer blades are al-
ways at right-angles to the central blade
(see fig. 9).
The working areas of the blades overlap each oth-
er. If the blades' position in relation to each other
has been altered, there is a considerable risk of the
blades striking each other. This can entail serious
damage to the cutting deck.

ENGLISH
If this is the case, take the machine and cutting
deck to a service workshop for repair and inspec-
tion.
REPLACING BLADES
Wear protective gloves when changing
blade(s) to avoid cutting yourself.
Ensure that the blades are always sharp. This pro-
duces the best cutting results.
Always check the blade(s) after a collision. If the
blade system has been damaged, defective parts
should be replaced.
Always use genuine spare parts. Non-
genuine spare parts can entail a risk of
injury, even if they fit the machine.
The cutting system comprises three blade bars with
two replaceable blades Y (fig. 10). When replacing
blades, both should be replaced to avoid imbal-
ance.
Install the new blades. Tighten screws V and W
properly. Tightening torque: V - 9.8 Nm, W - 24
Nm.
In the event of a powerful collision, the blades may
be bent out. Undo the locking nut X and fold back
the blade. Install a new genuine break bolt V.
Tighten the locking nuts X and Z.
