3.4 Tyre pressure
Adjust the air pressure in the tyres as follows:
Front: 0.6 bar (9 psi).
Rear: 0.4 bar (6 psi).
3.5 Basic setting
In order for the cutting deck to cut optimally, the
correct basic setting is required. The deck is in the
basic setting when its rear edge is 5 mm above its
front edge. This means that the deck is inclined
forwards.
Carry out basic setting as described below.
3.5.1 Basic setting, 125 Combi Pro, 107 M
HD
The deck is in the basic setting when the actions
under 3.1.1 and 3.2.1 have been carried out.

See fig. 17 and perform basic setting of 107 M and
121 M as follows:
1. Place the machine on a level floor.
Requirements for floor flatness: ±1 mm/m. No
slope towards a floor drain or similar may occur
in front of or behind the machine.
2. The tyres must have the correct air pressure.
See 3.4.
3. Place the deck in transport position and lay a
plane-parallel plank under the deck.
4. Place a 5 mm tall spacer on the plank under the
rear edge of the cutting deck, and lower the
deck to the working position.
