WARNING!
Before starting to operate the forestry tong, you must have read this manual thoroughly.
The owner of the winch is responsible for ensuring that all operators and assistants are familiar with the
forestry tong’s operation.
Caution!
1. Never attempt to use this forestry tong without sufficient training.
2. Use this equipment only after thoroughly reading and digesting the contents of this manual. Further copies
of the manual are available on Tel. +45 98 63 21 22. If machine labels become illegible, these can also be
re-ordered.
3. Keep hands, feet and clothing away from moving parts.
4. Before starting the forestry tong, make sure that the cable is in good condition. If the cable breaks, cable
fragments may be thrown in all directions. Ensure that all persons are at a safe distance from the cable
while the forestry tong is in use.
5. Only handle the cable after stopping the PTO
6. Do not transport logs directly on the cable. Always use the proper chain tree.
7. Use the forestry tong only for towing logs.
8. Inspect the moving parts. They must be correctly fixed and in good condition. All safety guards must be
correctly fitted.
9. Make sure you are familiar with the controls and know how to turn off the forestry tong and tractor engine
in case of emergency.
10. Children and untrained persons must not be allowed to operate the forestry tong.
11. Do not wear loose clothing, sleeves, ties or long, uncovered hair in the vicinity of the machine.
12. Prior to working, make sure the forestry tong and tractor are standing on a level piece of ground.
13. When operating the forestry tong with the operating strings you should stand at a side-ways distance of
least 4 m from the machine. Do not operate the forestry tong from the tractor seat unless a strong
protective shield is fitted.
14. Ensure that other persons are not at risk from the operation of the winch.
15. Do not let the tractor run unattended.
16. Use only original spare parts from Fransgård, and do not alter the equipment in any way.
17. All persons working with the winch must be taught about the dangers and how to prevent accidents.
18. Be observant at all times! Do not work with the forestry tong when tired or exhausted.
19. Do not operate the winch over side-angles of more than 30°.
20. Disregard of the warning labels on the machine or the safety precautions in the manual could lead to
serious or fatal injuries.
21. The tractor must not be set in motion while the lower log ends (of the towed logs) are still resting on the
ground. If the logs have not been raised and then strike an obstacle, this may cause the tractor to tip over,
resulting in serious injury.

SAFETY PRECAUTIONS, OPERATING INSTRUCTIONS FOR VHZ-2300.
1. Work safely! Observe all safety precautions.
2. Entrust the operation and maintenance of the forestry tong only to suitable and reliable persons familiar
with this work and over 18 years of age.
3. Prior to use and at least once a day, check that the forestry tong is working smoothly and correctly. Defects
must be repaired to a workmanlike standard. In addition a qualified person prior to first use and after major
alterations, and never less than once a year must inspect the winch.
4. Prior to maintenance of the winch, uncouple the PTO and stop the tractor. Remove the key in order to
prevent inadvertent restarting.
5. Do not disable safety equipment on the winch.
6. As the traction mechanism, use only static cable of sufficient strength corresponding to the indications on
the maker’s plate in these operating instructions. The breaking force of the choker and towing chains must
be at least double that of the pulling force of the lower cable position marked on the winch.
7. Replace faulty cable promptly.
8. Use only a cable of such length that when fully wound onto the drum the upper cable position does not
exceed the edge disks by more than 1.5 times the diameter of the cable.
9. Before starting the forestry tong, the operator must ensure that no persons are at risk.
10. The forestry tong must only be operated from a safe position, such that the winch itself, the load, the cable
or the fastening devices do not endanger the winch operator. The driver’s seat on the tractor is considered
a safe position if a sufficiently sized protective grille is arranged between the winch and the driver’s seat.
When operating the winch from outside the driver’s seat, a similar protective arrangement must be
provided for the winch operator, e.g. the tractor itself, a protective grille projecting a sufficient distance to
the side of the winch, or a safe position at a sufficient distance from the tractor, e.g. behind a tree.
11. The winch operator must ensure that, except in the case of danger, at least two winds of the cable
are left on the winch drum.
12. From his position the winch operator must always be able to see the towing load, or otherwise must
ensure that other persons watch the track of the load and that there is constant contact between
watchers’and winch operator by means of pre-arranged signals.
13. While the cable is being worked it is not permitted for any persons to stand in the area between the load
and the winch or in the danger angle between winch, diverter pulley and load.
14. When hoisting over slopes, no one may stand beneath the logs fastened to the cable.
15. When pulling on trees, which are still standing, the traction cable must be attached to the trees before
felling begins. In so doing the position of the tractor must be such that the distance to the tree to be pulled
down is at least double the height of the tree.
16. The tyre profile on the tractor on which the forestry tong is mounted must have good grip, i.e. the tyre
cleats must have at least 40% of the profile height of a new tyre, or the vehicle must be fitted with anti-skid
chains. In snow and icy conditions anti-skid chains must always be fitted.
17. The tractor must be secured with hill support plates or similar prior to starting work. If necessary, secure
the tractor with a cable opposing the direction of pull where the support plate blocks do not afford sufficient
holding power due to the gradient of the land or ground conditions.
18. Select towing load and speed such that the vehicle will not tip over as a result of its construction and type
or the gradient of the land and ground conditions. Select the lowest possible upper cable intake and the
optimal winch pulling direction, i.e. one without sideways deviation.
19. Set the machine on a firm and level basis. It is the responsibility of the owner and users to make sure that
any defects arising from use of the machine are repaired and that the safety conditions are met.
20. At regular intervals and at least twice a year inspect the connecting pins, Item 10, Page 24 for wear. If
necessary replace, as in the case of worn pins the clutch arm may seize up.

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 itlifts 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 necessarythe three-point of the grapple tong can be used to push log ends so theyare inline. Neverusethe
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 relativelyfar to the side, so itis
important to plan the route carefully. Only light steering is allowed.
H. During transport, the logs may “pack” a little, with the result that they have a smaller cross-section.Activatethe
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 normallyare 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 forestrytong without logs, the grapple must be closed completely,andtheswivelplaced
in the center position where hydraulic locked.

INSTRUCTIONS FOR USE.
Assembling the equipment:
Attach the forestry tong to the tractor’s three-point suspension.
Adjust the length of the top-link so that the machine will not interfere with the tractor cabin and the winch stands
straight.
Check the length of the power take-off shaft both in working position and in transport position and if necessary
shorten it.
Insert the cable via the upper pulley and mount on the drum. Lock the cable to the drum with the cable
fastener (Item 30, Page 5). Make sure that the cable is properly attached and undamaged. The cable must be
fully rolled out and coiled up under load before being rolled onto the drum.
Loosen the brake before unwinding the cable:
Lower the forestry tong until it is standing on the ground, and pull the red cord slowly until the fitting (Pos. 39
page 3) grips the fitting (Pos. 38 page 3) firmly.
Rewinding the cable:
Choose a safe place to stand with a clear
view of the tree trunks.
Then pull the green cord (Pos. 9 side 1).
The fitting (Pos. 38 page 3) is released
automatically when you pull the green cord.
To prevent unnecessary wear and tear on
the coupling surface, pull the green cord hard
enough to ensure that the fitting
(Pos. 24 page 1) is as illustrated.
WARNING! When the cable is under load, the brakes must only be released with the red string (Item 39, Page
3). Keep a safe distance!
Hauling:
Attach the log firmly to the chain tree and lift the tractor winch until the ends of the
logs are free of the ground.

LUBRICATION AND MAINTENANCE:
Lubricate the cardan shaft once a week.
Lubricate all slide connectors once a week.
All ball bearings are permanently lubricated.
The chain must be greased every 50 working hours. The machines must be detached.
Take care that no oil or grease falls on the clutch lining.
Grease daily the upper cable roller as required through the lubricating nipple on the turning plate.
SETTING THE BRAKE AND THE FREE WHEEL BRAKE.
It may become necessary to reset the brake after a few hours’ operation.
1. The distance at Pos. 1 must be 30-40 mm. under load. If the distance is less, this should be adjusted with
the two nuts (M10) at Pos 2.
2. The free-wheel brake, Pos 3, should be adjusted as required by tightening the handle.
The free-wheel brake is to prevent the cable drum coasting when the cable is paid
