INSTRUCTIONS FOR USE
Transporting long logs:
A. Always put the swivel cylinder into “floating” position, so the swivel cylinder is able to
turn freely when steering with the tractor, when transporting long logs.
Important! The log ends are only to be placed 10-20 cm inside the grapples (see F.)
B. Log ends are only to be lifted a little of the ground, and absolutely not so much that the
back end of the logs are of the ground. The weight of the load will otherwise be so
heavy that it lifts the front wheels off the ground, making it difficult or impossible to
steer.
C. Always use the oblong top link hole by transport of long logs.
D. Take into account the need for adequate space to be available.
E. The maximum turning with the grapple tong is a +/- 43 turning angle in connection to
the tractor, if this is exceeded the grapples needs to be opened a bit, otherwise the
construction of the grapple tong will be overloaded.
Transporting short logs:
G. If necessary the three-point of the grapple tong can be used to push log ends so they
are in line. Never use the grapple for this purpose.
H. When the grapple tongs are closed right round the logs (the two grapples overlap each
other) the logs can be lifted free of the ground and transported.
I. Depending on the lifting abilities of the tractor, 2 –3 m logs can be unloaded in
stacks of 1.2 m height.
WARNING!!!
C. Be especially careful on uneven terrain.
In such situations the forestry tong must be lowered immediately, so the rear end of
the logs always rests on the ground. As the hydraulics are in the “floating” position, the
consequences of allowing long logs to hang freely in the air can be that they may swing
out to one side and result in overturning the tractor.
Never use the oblong top link hole, by short logs lifted out of the ground.
D. When steering during transport of logs, the rear end of the load will be swung relatively
far to the side, so it is important to plan the route carefully. Only light steering isallowed.
H. During transport, the logs may “pack” a little, with the result that they have a smaller
cross-section. Activate the grab cylinder occasionally during transport, so that the
tongs tighten their grip, and do not drop the logs.
J. When transporting 2 –3 m logs, which normally are able to lifted clear of the ground,
the swivel cylinder must not be in "floating" position but shall be swiveled over and
hydraulic locked in the center position.
J. When driving with the forestry tong without logs, the grapple must be closed
completely, and the swivel placed in the center position where hydraulic locked.
