INSTRUCTIONS FOR SAFE WORK
When operating the winch, you must devote maximum attention to safety! To prevent
accidents, carefully read and follow the instructions below.
1. General:
1. Apart from the instructions in this user manual you should also observe all general safety
and accident preventing regulations.
2. When working with the winch, it is necessary to comply with the rules of safety at work.
3. Only persons, who are older than 18, are allowed to work with the winch.
4. Safety and warning plates on the machine provide important instructions for
safe use. Observe them for your safety.
5. The winch or its flawless operation should be checked before every use or at
least once every working day. Defects should be removed by an expert. Before first use
or after significant alterations and at least once a year the winch must be examined by
an expert.
6. When using public transport routes observe traffic signs and regulations.
7. When using the winch wear personal protective equipment(helmet, gloves,
appropriate footwear,...).
8. Before starting and driving check the surrounding area (children). Maintain
adequate visibility.
9. Riding on the winch during transport is not allowed.
10. Connect the winch according to the instructions.
11. For on road travel the machine must be in the following condition. If the winch covers
the rear lights of the tractor and they are not visible during transport on public roads,
install additional lights on the winch.
12. Adjust the driving speed to the environmental conditions. When driving up or
down or across a slope avoid sudden turning of the steering wheel.
13. Do not stand in the danger area.

5
14. If the tractor is not blocked against moving with a brake or wheel blocks, no person
should be standing between the tractor and the winch.
15. Do not touch the winch until every part of the winch has stopped.
16. Check mounting bolts regularly.
17. Before use the winch must be visually inspected. At least once a year, the winch must
be inspected by a professionally qualified person.
18. During any work on the winch you must turn the tractor off.
19. It is forbidden to remove the safety devices from the winch.
20. Use a tow rope of adequate strength and quality (see the factory plate).
21. A damaged wire rope must be replaced immediately.
22. It necessary to use a wire rope of an appropriate lenght. When you wind the rope up,
a distance of 1,5 of rope diameter to outer diameter of the drum should stay on the
drum. When you unreel the rope, a minimum of 3 rope wraps should stay on the drum.
23. The assistant is not allowed to connect load on the winch until he has informed the
tractor driver about it.
24. It is especially dangerous to stand next to the tree that you are about to pull
(Figure 1).
25. When using a relay pulley there is a triangular danger area, where you are not
allowed to stay during the tow (Figure 2).
Figure 1 Figure 2
26. When towing observe the maximum allowed angle of 30º (Figure 3).
27. On uneven terrain or when not observing the maximum allowed towing angle there is
a danger of the winch rolling over (Figure 4).

6
Figure 3 Figure 4 Figure 5
28. Do not use the winch for unintended purposes (lifting loads, etc.).(Figure 5)
29. Tractor driver and assistant must continuously communicate during their work.
30. The winch operator must continuously observe the load during the tow. If this is not
possible due to the configuration of the terrain, the assistant should help.
31. The tractor to which the winch is connected to must have a minimum tyre profile
which still meets the traffic regulations. Otherwise the wheels must be fitted with snow
chains. Chains are also obligatory when working in snow and ice.
32. When disconnecting the winch, you first need to choose an appropriate hard
and flat surface. Fix the winch by means of support legs. Lean the drive shaft on the
prepared holder.
33. In the area of the three point linkage there is a danger of injuries due to
compression or crushing.
34. The winch can be operated only from a safe place from which the load, wire rope,
rope hook or the winch itself do not pose a threat to the operator. A safe place can
also be the tractor seat if the winch has a safety net of sufficient size. When operating
the winch outside the tractor seat the operator must be provided with an appropriate
protection, e.g. the tractor itself, secure location at a sufficient distance from the
vehicle, e.g. behind a tree. Logs can be monitored from the side next to the
connection and shorter timber can be monitored diagonally behind the load. (See
Figure 6).
35. During the tow, it is forbidden to stand between the load and the winch as well as in
the danger area between the winch, relay pulley and load. (See picture 7).
36. Before operating the winch, make sure that the winch butt plate is securely anchored
to the ground. In the event of soft ground, steep slopes or when pulling heavy loads,
the tractor must be fastened with an additional rope or chain. This will prevent the risk
of slipping or even overturning of the tractor.
37. Adjust the speed of load pulling and the size of the load to the tractor’s power
capacity. You should also pay attention to the inclination of the slope and the terrain
to avoid a rollover and to maintain a safe steering and braking performance.

INSTRUCTIONS FOR USE
1. Description
The winch is a machine intended for storing chopped logs from the forest. Basic parts of
the winch are: welded housing, drive part, drum with shaft, clutch, brake, upper and
lower pulley and other smaller elements. Control is done by electro hydraulic system.
Clutch and brake are engaged by hydraulic cylinders. Pressure in the hydraulic part is
created by the hydraulic pump, which is driven by the PTO shaft. Hydraulic battery
maintains required pressure in the system even after the pump becomes still or the tractor
is shut down, which still enables to unwind the wire rope. Steering elements are powered
by electricity from the electrical socket at the rear of the tractor. The winch operates with
hydraulic pressure to maximum 160 bar.
Safety valve is factory set and the pressure is not allowed to be increased!
Required equipment of the tractor
- PTO shaft with chosen gear ratio, max. 540 RPM.
- Three-point hitch of I and II category.
- Electrical installation 12 V with socket on the rear of the tractor.
Maximum number of revolutions and direction of tractor PTO shaft rotation is 540 min-1.
PTO shaft adjustment
Length of PTO shaft needs to be adjusted for different tractors (figure F1-F4). For winch
65H/85H/65Hpro/85Hpro, the use of PTO shaft with torque 695 Nm (type W 400E
Walterscheid) is appropriate.
Ascertain the accurate length in the following manner:
1. Shut down the tractor.
2. Connect the machine to the tractor.
3. Extract the PTO shaft apart and connect the individual shaft halves to the tractor
and machine and compare them crosswise and mark them (figure F1).
4. Shorten external and internal plastic protection pipes (figure F2).
5. Shorten external and internal slide profiles with the same distance as plastic
protection pipes (figure F3).
6. Crop the pipe end, remove fillings and grease the slide positions well (figure F4).

9
Tractor mounting
When connecting the winch, do not stand in the danger zone!
Forestry winch can be connected to any tractor, which has a three-point hitch, with
connection frame of category I or II. Appropriate construction also enables easy
connection to the tractor with automatic connection rods. Connect the prescribed PTO
shaft and secure cardan protection with a hang chain. Be careful that the cardan clicks
into place on both connection points! For transfer of torque from the tractor to the winch,
it is advisable to use a PTO shaft with a clutch. Once the winch is attached to the tractor,
strengthen the stabilizers on the lower connection rods and level the winch with a hitch
nut into position, so that the winch is tilted backwards for approximately 20 degrees.
Electrical cable plug on the winch is connected to the socket on the tractor. Steering
console is connected to the socket on the winch housing. When using remote control,
receiver cable is connected to the socket, where the steering console used to be.

10
Wire rope unwinding
When the winch is properly connected, we can begin with unwinding of the wire rope.
On tractors without a socket with constant current of 12 V, we can connect a supply
cable in the socket, which is usually made for connection of light equipment on the trailer.
Because of this, we have to turn on the position lights.
On the steering console (figure 8), press the left button to release the brake. Hydraulic
cylinder shifts to position 1. If we disengage pressure on the button in less than 3 seconds,
the brake cylinder shuts and the winch is again open and unwinding is not possible. If this
button is pressed for more than 3 seconds, the function shifts from “impulse” to “constant
release” and despite not holding the button, the cylinder stays in the open position and
the winch in unwinding function.
When unwinding, we have to be careful not to unwind the wire rope completely or leave
at least three winds on the drum. This distance is marked on the wire rope. Due to safety
reasons, the wire rope is installed on the drum so that if the logs start to slide without
control, the rope must “pull” itself off the drum. If the rope was pulled out with excessive
force, we can pull out the entire wire rope during pulling. In this case, replace it according
to the procedure, foreseen for wire rope installation.
If the wire rope is very tight and we wish to release it, we have to do it impulsively with
quick presses 2-3 times on the left button. This prevents the wire rope to unwind too quickly
from the drum and that the wire rope is not too loose. It also prevents the logs to slide
downhill.
Warning
Steel rope must be completely unwound before first use and wind it back on the
generator drum under load.
For instance, we can do this so that we attach the rope to a standing tree and pull the
tractor with slight braking to the tree. This procedure must be done also before trying to
tow, if we towed downhill beforehand or if the rope was wound loosely during towing.
ATTENTION!
Loosely wound steel rope can be damaged (stuck, bent) at greater load, so that it is
prohibited to use it again.
Warranty does not apply for a steel rope, which is damaged in such manner.

Winch controler
We can start pulling, when the winch is on the ground and properly strengthened. Apply
the hand brake on the tractor. If the PTO shaft is engaged and the hydraulic system
requires pressure, we can start pulling. Press the right button on the steering console (pos.
2, figure 8). The wire rope starts winding on the drum. When we release the button, the
winding stops.
If the unwinding of the wire rope does not stop immediately after releasing the button, the
winch is malfunctioning. Immediately stop work and contact service company, because
operating the winch in this case is deadly!
During pulling it is forbidden to lift the winch, because this can damage the connection
PTO shaft on the winch.
In case of ultra vires or danger of accident, immediately press the red button (pos. 3) to
put the winch in a standstill.
The SMART 3in1 function
If your winch is equipped with an unwinding device (Hpro version), it icludes the SMART
3in1/ TERRA function.
It can only be operated using a corresponding remote controller.
When the winch is started for the first time, use the manual console and test its operation.

After making sure that the winch operates properly by using the manual console, you can
test the winch with a remote control.
If the winch is not responding, your remote control is not suitable. In this case, replace the
remote control or put the winch into the classic mode. To do this, follow the procedure
below.

SETTINGS
Figure 9
1. Clutch
Before any modification on the winch, shut off the tractor engine!
Pulling force on the clutch is factory set and does not require to be changed. Due to
wear of friction surfaces, distance between clutches needs to be set after a certain
period. This is done once a year at usual work in the forest or after every 1000 m3of pulled
out logs, but not before end of warranty period.
Perform the setting by unscrewing the nut (pos. 9, figure 11), which is the safety nut, to the
left. Then, tighten the high nut (pos. 15, figure 11) to the right. In this position, there is no
distance between the clutches. Then, unwind the nut for one turn to the left –this creates
a gap between the lamellas of approximately 4-5 mm. Retighten the safety nut (pos. 9,
figure 11) to the right. This protects the high nut from unwinding. Engage the motor and
PTO shaft, pull out the rope and begin controlling the adjustment.
If, despite not engaging the right button for pulling, the rope starts to move, then the
distance between the clutches is too small. Increase it for approximately 1 millimeter or
repeat the setting procedure by unwinding the high nut for ¼ of a turn to the left.
Engaging pulling is not allowed, if the nuts (pos. 9 and 15, figure 11) are not installed on
the shaft, because the hydraulic cylinder of the clutch gets damages, because the
maximum permitted travel is only 8 mm!
WARNING
If the cylinder stroke is greater than 8 mm, oil can leak on clutches.
Preliminary brake
Set the pre-brake with screw (pos. 4, fig. 11) and nut (pos. 5, fig. 11). By rotating the bolt to
the right, the brake force is increased, with rotating to the left, the brake force is
decreased. Then tighten the wing nut, which prevents the bolt to loosen automatically.
Proper setting ensures that the wire rope does not roll off the drum automatically or
excessively. This would cause loose winding and damage to the wire rope at fast
disburdening of the brake and unwinding. Preliminary brake is properly set when
unwinding of the rope is still possible without excessive effort. If you pull the rope uphill, it is
possible to additionally disburden the brake, so that rope towing is easier, the bolt (pos. 4,
figure 11) must be returned to its original position immediately after.

15
Brake
At the end of pulling, the differential brake automatically engages. Brake is factory set to
brake force, which is 25% greater than the nominal towing force of the winch. By wear of
the brake pad, the brake force changes, therefore it has to be set again. This is needed,
when the brake does not hold the load as described in the beginning of this paragraph.
Set the brake force by loosening or tightening the screw (pos. 2, fig. 11) and loosen the
safety nut (pos. 3, fig. 11) beforehand. When tightening the screw (pos. 2, fig. 11), the
brake force decreases, and when loosening the screw, the brake force increases. After
finishing setting tighten the safety nut (pos. 3, fig. 11). Correctly set band brake in the on
position disables the load to slide backwards, and in the off position, it enables smooth
pulling of the rope from the winch.
Figure 10
Figure 11

16
Drive chain tensioning
After a certain period of operation (10 hours), the drive chain stretches; therefore it must
be checked frequently and tensioned, if required. It must be checked every 500 hours of
operation. Tensioning is done according to the following procedure (figure 12)! First,
disengage the PTO shaft and turn off the engine. Remove the protective sheet of the PTO
shaft (pos. 1, fig.12).
Loosen the nuts (pos. 2, pos. 8, fig. 12), which fix the lower drive (pos. 3 , pos. 9, fig. 12).
Then loosen the safety nut (pos. 12, fig. 12) and use screw (pos. 13, fig. 12) to tension the
longer chain (pos. 6). Turn this screw to the right until you set the correct tension of the
chain. Chain is correctly tensioned when it still swings approx. 3 to 4 mm in the transverse
direction. Them, with the counter-nut (pos. 12, fig. 12), tighten the screw, which prevents
the tensioning device to loosen.
Now securely tighten all four nuts on the lower drive (pos. 2, fig. 12). Then start to tension
the shorter chain (pos. 8, fig. 12). If you have already loosened the four nuts (pos. 8, fig.
12), loosen the nut (pos. 11, fig. 12) and start turning the tensioning screw (pos. 10, fig. 12)
to the left. This increases the distance between both housings. When the chain (pos. 7, fig.
12) is properly tensioned, tighten the nut (pos. 11, fig. 12) and other nuts (pos. 8).
Figure 12
Wire rope assembly
First, remove the triangular protective net on the winch column. Then rotate the cover
(pos. 7, figure 11) and rotate the drum in a position, which enables unscrewing of the bolt
(pos. 8, figure 11)on the drum. Insert the wire rope in the guide of the upper pulley and
direct it through the upper pulley to the rope drum. Insert the rope in the groove and
tighten the bolt (pos. 8). Then start to wind according to the procedure, which applies to
towing. Once the entire length of the wire rope is wound, unwind it again and wind it
again strongly according to the procedure, which is described in the chapter “Wire rope
unwinding” to prevent damage to the rope.

17
Operation
The device begins to unwind the wire rope automatically, when you release the wire rope
or when the function for wire rope unwinding is set on the brake. The wire rope is being
unreeled until you stop the unreeling function on the winch. After the machine is turned
on, the steering system ensures the engagement of the hydraulic cylinder in the
unwinding position. After three seconds, the oil flow is redirected to the hydraulic motor of
the upper pulley. The non-return valve, which is connected to the brake cylinder, enables
a stable position of this cylinder. When in use, all regulations for safe use of the winch must
be observed. Unwinding speed depends on the oil flow or the PTO shaft speed, which
must not exceed 540 revolutions per minute.
After the function for unreeling the wire rope has been activated, the speed of the wire
rope is a bit higher at the beginning, before it decreases. Considering the system of
operation, this is completely normal.
Only the speed decreases and not the force used to unreel the wire rope of off the drum.
Settings
After the assembly and testing, the machine is set. If the machine does not start
unwinding the rope, when you turn it on, you must adjust the settings.
Observe the following procedure to adjust the settings.
If the wire rope is not wound onto the drum tight enough, unwind the rope. Then wind the
wire rope again and make sure it is installed tight enough (use a load). To ensure an
appropriate functioning of the reeling machine, do not use a damaged wire rope
(creased or torn wire rope).
When you start unreeling the wire rope with the machine, the force of the safety brake
should be set in such a way that the wire rope does not begin unrolling on the drum
(check instruction for use of winch; setting the safety brake). Next the thrust of the smaller
pulley (pos. 3, figure 12a) on the larger pulley must be set. If the rope is slipping on the
larger pulley (2), you must increase the thrust of the smaller pulley using the setting screws
(4). In case the larger pulley (2) is not spinning, you must decrease the thrust of the smaller
pulley (3) using the setting screws (4).
When the machine is unreeling the rope properly, you can slightly increase the force of
the safety brake on the drum. This ensures an even rolling of the wire rope up onto the
drum. If you are using an additional brake, it is important that the larger pulley (2) is
spinning together with the wire rope (it should not be slipping) when you are rolling the
wire rope up onto the drum (there is no load on the wire rope). The setting is carried out
according to the above mentioned procedure.

18
Diameter of the reeling machine wire rope
During the construction of the wire rope reeling machine certain parameters were
considered, which should be taken into account while using it to assure a quality lifetime
of the machine.
The radius of the wheel edge must be identical to the diameter of the wire rope. For
winches with different traction forces use the following wire ropes:
MODEL
65H
65Hpro
85H
85Hpro
WIRE ROPE
(ø 11), ø 12, ø13
The use of a wire rope with an improper diameter can seriously impair the functionality of
the machine. (The use of ø 11 wire rope is allowed only under certain conditions.)
If the wire rope is damaged (torn, crumpled), it is practically impossible to unreel that part
of the wire rope. In such cases complaints do not comply.

Adjusting the unwinding speed
The 55Hpro winch is equipped with a valve for adjusting the unwinding speed. With the
45Hpro winch, this is available as optional equipment.
The unwinding speed of the wire rope is adjusted according to the following procedure:
Figure 12b
-To increase the unwinding speed, rotate the valve
(5, Figure 12b) in the counter-clockwise direction.
-To decrease the unwinding speed, rotate the valve
(5) in the clockwise direction.
-If the valve (5) is turned all the way, the wire rope
stops unwinding.
Adjusting the limit switch
The limit switch is adjusted for operation after the assembly and test. In the event of
incorrect operation, a subsequent adjustment may be required.
Figure 12c
Before adjusting the limit switch, turn of the tractor's engine and disconnect the power
supply to the winch.
Remove the protection of the switch (6, Figure 12c). Unscrew the safety nut (7) on the limit
switch (8). Press on the sleeve (9) until it rests in its final position. Screw on the sensor (8)
until it reaches the surface of the sleeve (9). Unscrew the sensor (8) by one turn, so that
the distance between the sensor and the sleeve (9) is 1 mm.
Check the operation of the limit switch:
When the sleeve (9) is released, the sensor (8) is not active (the sensor lamp is off). Move
the sleeve (9) by 5 mm (the sensor lamp flashes). Press on the sleeve (9) until it reaches its
final position (the lamp is on).
If the sensor operates properly, fasten the cover of the sensor (6) back onto the rope
guide.

Maintenance lubrication
Before proceeding with maintenance work, shut down the engine, remove the key and
wait for all moving parts to stop.
There is a grease fitting on the winch, which enables greasing of the upper pulley and
guide. The second grease fitting is on the housing of the lower pulley. Greasing is required
every 60 hours of operation. The PTO shaft needs to be lubricated according to
instructions of the manufacturer.
Non-frequent greasing can cause wear of slide elements and consequentially a defect,
which is not subject to warranty terms!
Drive chain must be lubricated every 200 hours of operation. Lubricate it with spray for
lubrication of chains or special grease, which does not melt at high temperatures,
because the grease can come into contact with friction coating of the clutch.
First, remove the cardan shaft protection, which must be fitted back
after finishing lubrication. Clean the chain before lubrication. Do not
lubricate the part, where the grease can reach clutch with application.
If grease comes into contact with friction coating of the clutch due do improper and
excessive lubrication, this would mean a drastic reduction in pulling force and
consequentially it would be required to replace the blades of the clutch, which cannot be
a subject of this warranty!
All other bearings on the winch are of closed type, therefore greasing is not necessary.
CONTROL OF HYDRAULIC OIL
Oil level in the tank needs to be controlled occasionally.
Oil level in the tank is 3 liters.
Hydraulic system uses oil for hydraulic systems ISO 32. First oil change must be done after
100 hours of operation. Each next change must be done after 1000 hours of operation or
at least once a year. Oil temperature must be checked during operation. If it exceeds 70
°C, the cardan must be stopped and determine the cause of overheating. If you do not
have a thermometer present, you can determine the oil temperature by touching the
hydraulic line. This must be done only with the engine switched off or else the hydraulic
system can malfunction.
Oil level is controlled with stick on the tank cover (fig. 13).Here you also fill in oil.
With any work on the hydraulic system, pressure in the system must be released. Do this
by pressing the left button on the control console (pos. 1, fig. 8) several times, until the
pressure drops to 0 bar (pos. 1, fig. 14).
Remove the triangular protection on the winch pillar and cardan protection beforehand.
Release the oil from the tank (fig. 13) on the tube, which goes from the pump to the tank.
There is a filter on the bottom of the tank, which must be replace with every oil change.
High-pressure filter (pos. 2, fig. 14) must also be cleaned.
