INSTRUCTIONS
WARNING!!!
Pay close attention to these points: all safety instructions are marked with this symbol, it is
extremely important that you read them.
1. Become familiar with the instruction book, read the safety instructions through
carefully. Before beginning to use the forestry tong, the user (the person that is to
manipulate the forestry tong) must be familiar with this instruction book, i.e. have
read it.
2. The user must be minimum 18 years of age.
3. The user must not be under the influence of alcohol, narcotic substances or
medicines.
4. All loose parts that do not belong to the machine must be removed.
5. All directions for use must be studied carefully.
6. Position the machine in such a way that it cannot move during: maintenance, cleaning,
adjustment, assembly of accessories or spare parts, as well as under storage.
7. The construction of the machine must not be altered if it jeopardizes safety in any way.
8. Do not use the machine for other purposes than those described in the instruction book.
9. The safety radius is 20 m. There may not, at any time, be people inside this area, when
the machine is in use. Pay particular attention to children in the vicinity.
10. Never leave the forestry tong hanging freely in the air.
11. Do not wear clothing that is ripped or too large (can catch the hydraulic levers).
12. Always operate the forestry tong from inside the tractor, never from the outside.
Standing under the forestry tong or its load is extremely dangerous and must not be
allowed.
13. After one hour’s use, check that all nuts are tight. Thereafter, check them regularly.
14. Pay attention to any possible leaks from the hydraulic system. Any leaks must be
corrected immediately. NB! Oil pollutes the environment.
15. When mounting the valve for “swimming” position (extra accessory) it is important to
ensure that the hydraulic hoses are well protected.
16. Use only original spare parts and accessories.
17. The forestry tong is intended to be used for the local transport of tree trunks from the
felling area to the intermediate log dump. Transport on public roads is not allowed.

PERSONAL SAFETY!!!
Working in conditions with high levels of noise can lead to hearing damage, and even to
deafness. The noise level depends to some extent on the cabin insulation of the tractor, so
if necessary, use suitable hearing protection.
Avoid physical contact with the oil during maintenance/repairs; use gloves.
ROAD TRANSPORT!!!
- During transport on public roads, all applicable laws must be followed regarding lights
etc., as well as fitting of warning triangles on the tractor.
- Keep reflectors and lights clean.
- Warning! Due to changes in weight, the steering abilities of the tractor will be reduced.
- Absolutely no load is permitted in the forestry tong during transport on public roads.
SAFETY PRECAUTIONS DURING USE
For the implement to work optimally, it needs to be inspected regularly. After 1 hour’s use,
all hydraulic hoses and cylinders must be inspected for oil leaks, and inspection must be
carried out at regular intervals in the future. If there are items of equipment or safety
equipment that are not specifically mentioned here in this instruction book, they do not
belong to the normal program from Fransgård.
CHANGES IN CONSTRUCTION
Changes in the construction of the forestry tong may only be made with the expressed
permission of the manufacturer. If this is not observed, then limitations to the normal working
capacity, reductions to the safety and expected working life of the machine must be
expected.
CHARACTERISTICS OF THE MACHINE (in brief)
The forestry tong is intended to be used for the local transport of tree trunks from the felling
area to the intermediate log dump, other uses are not permitted without prior permission
from the manufacturer. If any other use than that mentioned above takes place, it will render
the guarantee null and void.

CONNECTION to TRACTOR
The forestry tong is to stand in its normal position, i.e.: lowered onto a flat, solid surface,
resting upon the tong and the support leg. When this is ensured, connection is accomplished
as follows:
1. Drive carefully towards the forestry tong, so that the lift arms slide in between the
flanges. Make sure that the lift arms enter at the same level - this eases
insertion of the towing pins. Remember the cotter pin to secure the towing pins with.
2. Mount the top link.
3. Lift the forestry tong, but exercise caution; sudden lateral movement may easily occur,
as there is no oil in the hydraulic system. Adjust the tractors lift arms’ side limiters so that
the forestry tong is centered and locked into the middle.
4. Lift the support leg up to its top position and lock it into place.
5. Make sure that the hydraulic levers in the tractor are in neutral position.
6. Connect the hydraulic hoses to the hydraulic outlets on the tractor.
Swivel cylinder: connect to a double-acting outlet with free position.
Grab cylinder: connect to a double-acting outlet.
7. Fill the swivel cylinder with oil by way of the hydraulic levers first. During this procedure,
there should be ample room around the forestry tong, as it may, as previously
mentioned, react unpredictably due to air in the system. Run backwards and forwards a
few times so that all the air is removed from the system.
8. Now repeat the same procedure for the cylinder that closes around the trunks.
9. Measure the length of the hydraulic hoses; they should neither be too long or too short.
Pay particular attention to the danger of projections or other elements of the tractor’s lift
construction fouling the hydraulic hoses and if necessary tie the hoses down.
DETACHMENT from TRACTOR
1. Lower the support leg to its parking position, and lock it with the cotter pin.
2. Open the grapple tongs wide and lower the forestrytong onto a flat, stable surface. Adjust
the length of the top link so it is not tight when lowered.
3. De-activate the hydraulic control valve, and take off the hydraulic hoses.
4. Remove the top link and lift arms
5. Drive the tractor carefully away from the implement.

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.

SAFETY during MAINTENANCE
Before beginning maintenance tasks i.e.: adjustment, cleaning, assembly or repairs, the
following should be observed:
1. All power take-off equipment from the tractor must be disengaged.
2. The forestry tong must be positioned at the lowest position on a flat, stable surface.
3. Turn off the tractor.
4. WAIT until all moving parts have come to a standstill.
5. Support the forestry tong, so that it cannot move, even if the hydraulic levers should be
used.
MAINTENANCE
A thorough and always timely maintenance of the forestry tong is a good guarantee of
operational reliability and long working life.
- Always keep dismantled parts etc. clean during repairs.
- Make sure that no oil is allowed to drain out of the machine.
- Always use correct tools when dismantling parts, to avoid unnecessary damage.
- Always recognize defects at as earlya stage as possible, therebyavoiding further defects
and unnecessary additional expenses.
- Always use original Fransgård spare parts.
LUBRICATION
The forestry tong must be lubricated after each 16 hours running time, so all moving parts
are continually well-greased.
HYDRAULICS
Hydraulic hoses, pipes and outlets must be inspected regularly for leaks, faults or indication
thereof. In order to avoid further damage, worn or broken parts must be replaced
immediately.
When assembling hydraulic components it is important that hoses are cleaned and dust,
rubber residue, etc, are removed before assembly.

8
RENEWAL of HYDRAULIC HOSES
Correctly fitted hydraulic hoses last longest!
When replacing, please note the following:
- Keep the hose clean –both inside and outside.
- Make sure that the hoses are placed according to the instructions, and that they are free
to move in all working directions.
- The hoses must not be twisted, as this reduces their working life considerably.
- After assembly, the hose-joints should be inspected for any leaks.
ORDERING SPARE PARTS
When ordering original Fransgård spare parts, please quote the following:
- Machine description
- Production number
- Order number of the required spare part
- Name of spare part
- Name and address of orderer.
- Required method of dispatch (urgent/normal)
STORAGE
If the forestry tong is not used for any long period of time, it should be stored in a safe and
dry place.
Before it is put away, it should be lubricated with grease through all grease nipples. If the
paint work has been damaged, it is a good idea to repaint the applicable parts. If the paint
that is missing has been worn away, it may be better to cover these areas with oil or grease.
DISPOSAL of the MACHINE
- Exercise caution when dismantling the machine, as many of the parts are very heavy.
- Make sure that the dismantled parts and oil is taken to a reutilizationunit and a registered
chemical disposal plant.
