SERVICE AND MAINTENANCE
PREPARATIONS
Unless otherwise stated, all service and mainte-
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.
LUBRICATION
The deck arms are equipped with grease nipples (fig.8).
Lubricate these after every 25 hours of operation
(or at least once per season) with universal grease.
MAINTENANCE TIPS
To make cleaning and maintenance easier, the cut-
ting deck can be folded up:
1. Set the cutting height setting to cutting height 5.
2. Remove the locking pins and release the rear
edge of the deck (fig. 5).
3. Secure the tensioning arm on the hook.
3. Force the belt off the machine’s pulley.
7. Fold up the deck to the vertical position (fig. 9).
CLEANING
After each use, the underside of the cutting deck
should be rinsed off.
If the grass has dried solid, scrape clean the underside.
If necessary, touch up the underside with paint to
prevent corrosion.
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 two blade bars with
two replaceable blades Y (fig. 11). 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.
POSITIVE DRIVE BELT
Both blades are powered inside the deck by a pos-
itive drive belt.
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.
Following a powerful collision, always
check that both blades are at right-an-
gles to each other (fig. 10).
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.
If this is the case, take the machine and cutting deck
to a service workshop for repair and inspection.
