7.4. Factor de amplificación de la deflexión
1. Select 4. Settings -> Parameters -> Other parameters.
2. Select the desired parameter by turning the control wheel and pressing the green button.
Feed 7.1
Feed -> Feed mode
● Select the mode you wish to use for feeding trees.
Manual
1. The driver presses the Feed backward- / Feed forward control buttons until the tree has been fed to the desired length according to the preselection.
2. Thereafter the driver completes the sawing by pressing the Saw control button.
Preselection
1. The driver presses the desired preselection button and the Opti2 system automatically feeds the tree to the length set for the preselection.
2. Thereafter the driver completes the sawing by pressing the Saw control button.
If the driver presses the Saw control button during the feed, the Opti2 system will feed the tree to the length set for the preselection and automatically take care of sawing. If necessary, the automatic sawing can be cancelled by pressing the Saw control button again.
AutoStart
1. The driver presses the desired preselection button and the Opti2 system automatically feeds the tree to the length set for the preselection.
2. Thereafter the driver completes the sawing by pressing the Saw control button. If the driver presses the Saw control button during the feed, the Opti2 system will feed the tree to the length set for the preselection and automatically take care of sawing. If necessary, the automatic sawing can be cancelled by pressing the Saw control button again.
3. The Opti2 system will then automatically feed the
tree again to the length set for the same preselec-tion. If you wish to use a different preselection, give the Saw control button a long press during sawing.
Feed -> Slipping detection enabled
● Activate/deactivate slipping detection.
Feed -> Branch hitting reverse -> Enabled
● Select whether or not the branch chipper should activate automatically. Branch chipper = If an obstacle on the trunk (e.g., a thick branch) stops the forward feed, it will activate the branch chipper that tries to cut the branch by repeatedly feeding the harvester head to the branch.
Feed -> Branch hitting reverse -> Pressure change - front knives
● Set the percentage by which the front delimbing knives' pressure is decreased when the branch chipper is act-ive.
Feed > Branch hitting reverse > Pressure change -rear knives
● Set the percentage by which the rear delimbing knives' pressure is decreased when the branch chipper is act-ive.
Feed > Branch hitting reverse > Pressure change -rollers
● Set the percentage by which the feed rollers' pressure increases when the branch chipper is active.
Feed -> Branch hitting reverse -> Off delay after start
● The delay that defines for how long the branch chipper feature is disabled after starting the feed.
Feed -> Branch hitting reverse -> Max number of repeats
● Define how many times the branch chipper will try to cut the branch.
Feed -> Branch hitting reverse -> Reverse distance
● The reverse distance in millimetres when the branch chipper activates.
Feed -> AutoStart -> Start delay
● The delay after which the Opti2 system will automatic-ally start feeding trees after sawing when AutoStart has been selected as the Feed mode parameter.
Feed -> AutoStart -> Off diameter
● If the trunk diameter is smaller than this diameter, the Opti2 system will not start feeding trees automatically after sawing when AutoStart has been selected as the Feed mode parameter.
Feed -> Butt reverse point
● Set the point to which the system will reverse in butt end delimbing and butt end debarking functions.
Feed -> Braking before min top diameter
● Define in comparison to the minimum diameter how many millimetres thicker diameter will switch from fast feed to semi-fast feed.
Feed -> Overfeed -> Enabled
● Enable/disable overfeed. Overfeed = Trees are fed over the target length and then reversed back to the target length. This way the delimbing knives will delimb the trunk in advance, which will allow easier trunk movement after sawing.
Feed -> Overfeed -> Distance
● Enter the overfeed distance in millimetres.
Feed -> Rollers open during feed
● Select YES/NO. If the selection is in the YES mode and the operator presses the Grapple open button during the feed, the tree feed will be stopped, and the knives and rollers will open automatically.
Saw 7.2
Saw -> Over-sawing -> Relative when felling
● Define how many percentages will be sawed in felling sawing after the saw blade has reached its target posi-tion, which the Opti2 system has calculated on the basis of the trunk diameter.
Saw -> Over-sawing -> Absolute when felling
● Define how many millimetres will be sawed in felling sawing after the saw blade has reached its target posi-tion, which the Opti2 system has calculated on the basis of the trunk diameter.
Saw -> Over-sawing -> Relative when cutting
● Define how many percentages will be sawed in felling sawing after the saw blade has reached its target posi-tion, which the Opti2 system has calculated on the basis of the trunk diameter.
Saw -> Over-sawing -> Absolute when cutting
● Define how many millimetres will be sawed in sawing after the saw blade has reached its target position, which the Opti2 system has calculated on the basis of the trunk diameter.
Harvester head X50: Saw -> Saw mode
Harvester heads H60, H6, H7, H7euca, H8 and H73e: Saw -> Automatic/Manual
● Select the mode you wish to use for sawing.
Manual
1. The Opti2 system will continue sawing until the Saw control button is released or the saw blade has reached its target position which the Opti2 system has calculated on the basis of the trunk diameter. If the Saw control button is pressed for the second time before the saw blade has returned to the saw box, the Opti2 system will continue sawing until the control button is released.
2. The saw blade will return automatically to the saw box.
Automatic
1. When the Saw control button is pressed, the Opti2 system will continue sawing until the saw blade has reached its target position, which the Opti2 system has calculated on the basis of the trunk diameter.
If the Saw control button is pressed for the second time before the saw blade has returned to the saw box, the Opti2 system will continue sawing until the control button is released.
2. The saw blade will return automatically to the saw box.
Saw -> Chain lubrication control
● Set the control power for the chain lubrication valve.
The greater the value, the more saw chain lubrication oil the valve will produce.
Saw -> Saw control -> Felling pressure (H6, H7, H8)
● Set the saw feed pressure for felling sawing. Saw cylin-der pressure value.
Saw -> Saw control -> Cutting pressure (H6, H7, H8)
● Set the saw feed pressure for sawing. Saw cylinder pressure value.
Saw -> Sawing -> Control current (H6, H7, H8)
● Set the control current for rotating the saw chain. The greater the current, the quicker the chain will rotate.
Saw -> Felling sawing while rollers closing
● Select YES/NO. If the selection is in the YES mode, the user allows felling sawing to be started even if the rollers are not yet in contact with the tree.
