3.1 Initial Actions
Before harvesting is started, the measuring equipment must be given
information of the motion range of the grapple by opening the grapple
with the key ”Grapple open” and then closing it with the key ”Grapple
closed”. If pieces with other dimensions than those included in the
system are wished to be produced, the preselection data must be
changed.
If harvesting is going to be started in a new working site or a new stand,
the pieces of which must be counted separately, the job number must
be changed. If the old data is wished to be saved, it has to be printed
out.
3.2 Supposed Tree Harvesting Sequence
The program of the measuring equipment supposes the trees to be
felled in the following sequence:
1. After the equipment has been switched on, the grapple must first be
used in opened and then in closed position, and the motion must be
of the right extent (the pulse range must be sufficient, look at section
"8.2 Pulse range calibration of diameter"), before the diameter is
displayed (if diameter is used). Measuring equipment will not
calculate the volume nor accept preselections, if the diameter is not
displayed. Thus, measuring faults are avoided. Even if the diameter
is not in use, the grapple must be opened and closed before the work
is started.
2. To grip a standing tree the grapple had to be opened and lifted up.
3. After the tree is sawed the grapple had to be lowered in order to feed
to the desired length.
4. The feed to the desired length starts when pressing the preselection
and, by continuous feed (look at section "7.2 Feed method"), also
after crosscut sawing (not after felling sawing). If manual feed is used
during automatic feed, the automatic feed is interrupted. The
automatic feed can be started again whenever wanted simply by
pressing the preselection key.
5. When the tree has stopped at the desired length, the tree can be
crosscutted and a new preselection can be made. The data of the
produced piece is saved in the statistics of the active preselection. If
trunk counter is in use, the trunk is added to that preselection, which
is active when the first sawing is carried out. The length value is reset
by sawing.
