− If too much urea is fed, the feeding can be reduced by decreasing the
urea feeding time
(K41). To same extent urea feeding can be
increased by increasing the setting.
− If there is not enough pressure in the urea pump (feed pressure is
low or feed is delayed), increase the
saw delay
(K33). Thus, the
pressure has enough time to rise.
4.5 Turn Left
The grapple turns to the left as long as the button is pressed down.
4.6 Turn Right
The grapple turns to the right as long as the button is pressed down.
4.7 Feed Forward
− When the key "Feed forward" is pressed, pump 1 starts and the feed
valves are controlled on, one after the other, with intervals according
to the pre-set
feed delays
(K34). Pump 2 starts, when the last
(uppermost) valve is opened. At the beginning of the feed, after the
first length pulse, the equipment gives a short control
Knives open
.
− When approaching the selected length, the feed outputs are switched
off step by step. First pump 2 is released and the uppermost valve is
closed. When the length has been reached, pump 1 is released and
the last valve (the lowermost direction valve) is controlled to close.
− When the tree has stopped, pump 1 starts again for the pre-set
pump
release delay
(K35).
4.8 Feed Backward
− When the key "Feed backward" is pressed, pump 1 starts and the
direction valves are controlled on with the pre-set interval
feed delays
(K34). At the beginning of the feed, after the first length pulse, the
equipment gives a short control
Knives open
.
− When the length has been reached, pump 1 is released and the
lowermost direction valve is controlled to close.
− If necessary, the feed backward function can be intensified by lifting
the grapple (see chapter "7.40 Tilt up during feed backward").
− When the tree has stopped, pump 1 starts again for the pre-set
pump
release delay
(K35).
