Driving wheels
The tire air pressure of the wheels - see technical data - must be checked often.
One should particularly ensure that the tire air pressure in both wheels is the same in order to
guarantee smooth travel.
In the case of new wheels or a new
-2-wheel tractor the wheel screws and nuts must be re-
tightened with 100 Nm (10kpm) or inspected. Otherwise always during servicing.
Mount the wheels with the tips of their chevron-treads pointing towards the front
(when viewing the wheels from above), this gives full traction power.

Clutch
When the engine is running or the traction drive is switched on (1st gear) the clutch handle
should be pulled. The clutch is set correctly if the clutch doesn't decouple until the last third of
the coupling path - see figure 28.
After the first operating hour the setting of the clutch must be checked and possibly readjusted.
Adjustable by means of a setting screw on the clutch handle - see figure28.
Depending on the usage case, the setting screw must be screwed in or unscrewed, so that the
clutch is correctly adjusted.
Afterwards, retighten the setting screw with a counter nut!

General
Beware of fuel and oil leakage, repair if necessary.
Check screws and nuts routinely for tightness and retighten if necessary.
Lightly lubricate all gliding or moving parts (e.g. gear change rod joint, Bowden cables) with
grease or oil particularly after cleaning with a high pressure cleaner!
