LELY SPLENDIMO PC 281 - Replacement of Knives; Change of Oil in Gearboxes

7.4Replacement of knives
Install supports underneath the cutter bar if it is lifted
from the ground, and you intend to carry out work to the
machine.
The mower knives come in 2 different versions for discs with
LH or RH rotation. The front of the cutting edge has to point
downward, viewed in the direction of rotation of the disc
(fig. 25).
The mower knives have two cutting edges. After one edge is
worn, the knife can be reversed so that the second edge can be
used.
- Knives should always be replaced in pairs in order to keep
the disc balanced.
- Replace worn or damaged nuts and knife bolts.
- Use new, self-locking nuts and tighten them with a torque
of 50-60 Nm (5-6 kgm).
7.5Change of oil in gearboxes
Change the oil of the gearboxes and the drive element of a
new mower (or after assembly of a new gearbox) after
approx. 30 working hours for the first time. After that, oil has
to be changed every 250 working hours.
• Fill the gearboxes (fig. 26 and 27) with the quantities of
GX85W-140 transmission oil as indicated in the schedule
