C.2 Adjustment of minimum system
pressure
If the minimum ground pressure relief is insufficient, or if a higher
adjustment is required by way of fixed setting, the minimum system
pressure can be adjusted.
Please proceed as follows to ensure this adjustment:
- Unfold the machine (see chapter 4).
- Untighten the securing nut A (fig. C-1) of the pressure adjustment
system.
- Adjust the allen headed bolt B that controls the pressure system.
By turning this bolt to the left, you increase the setting;
by turning the bolt to the right, you decrease the setting.
Attention: even slight turning of the bolt may lead to a substantial
effect.
- Secure the new setting by tightening the securing nut A.
- Check the setting on the gauge by changing the system pressure
(see § 4.3).
- Repeat the above mentioned steps until you have reached the
required adjustment.
ATTENTION: a lower pressure setting increases the risk of damage
to the turf, while a higher adjustment may cause the cutter bar to
float (in the latter case, it may be sensible to change the system
pressure along the lines of § 4.3).
