• Slowly turn the axle anti-clockwise until the drive
shafts stop rotating backwards and make a mark
on the transmission housing (RS).
• Slowly turn the axle anti-clockwise until the drive
shafts start to rotate forwards.
• Slowly turn the axle clockwise until the drive

on the transmission housing (FS).
• Turn the axle clockwise 1/3 of the distance
between the marked stop points.
• Hold the axle (M8) firmly and tighten the lock nut
(M17).
• Check that the drive shafts do not rotate in the
neutral position by slowly transferring the
steering arm to the neutral position from the

Transmission maintenance

Oil change

Most garden owners do not have tools for or
experience of changing transmission oil. The
transmission probably has a longer operational life
than other ride-on mower components, this makes
transmission oil changes less important for most
customers. However, the transmission's operational
life is increased if oil changes are made.
If the ride-on mower is used professionally, it is
recommended to change the oil firstly after 50
hours use and every 200 hours use thereafter.
The oil filter only needs to be changed if the trans-
mission is opened for repairs to be made.
The transmission holds 3.3 litres SAE10W/30
engine oil, class CD–SF.

If the drive shafts do not rotate backwards despite
the hexagonal axle having rotated a full turn, the
neutral position is to be adjusted in the following
way:
• Slowly turn the axle anti-clockwise until the drive
shafts start to rotate forwards.
• Slowly turn the axle clockwise until the drive
shafts stop rotating forwards and make a mark
on the transmission housing (FS) and the axle.
• Turn the axle clockwise 8° from the mark on the
transmission housing.
• Hold the axle (M8) firmly and tighten the lock nut
(M17).

Ineffective brake power

As the brake is only used as a parking brake, wear
is negligeable. If the brake power is nevertheless
ineffective, this can be adjusted:
• Release the three bolts (N12) which hold the
brake lining packet.
• Press on the brake lever so that the brake lining
centres itself around the brake drum and tighten
the three bolts with moment (27 Nm).
