    GENERAL Dear customer! We are pleased that you decided to purchase our machine. Forestry winch is a forestry machine of modern design, whose construction enables effective and safe work in the forest. Work in the forest can only be safe if you follow the instructions for safe work and use.

  • Page 3: Intended Purpose

    1. Intended purpose The machine is intended exclusively for normal work in the forest. Any other use outside of this framework holds as unintended. This winch can only be used for pulling loads on the ground. The manufacturer is not liable for damages, resulting from unintended use. In this case, the user is the sole bearer of risk.

  • Page 4: Instructions For Safe Work

    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.
  • Page 5 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.
  • Page 6 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.

    Oscillating rope Tow rope Torn-off-pulley Triangle area Pulley Danger area Tree Figure 6 Figure 7 2. Pto shaft Only PTO shafts, which are prescribed by the manufacturer, can be used. Cardan protection pipes and protection funnels and connection protection must be installed, which must be in perfect condition.

  • Page 8: Instructions For Use

    3. Pto shaft adjustment Length of PTO shaft needs to be adjusted for different tractors (figure F1-F4). For winch 45H/55H/55Hpro, the use of PTO shaft with torque 695 Nm (type W 400E Walterscheid) is appropriate. Ascertain the accurate length in the following manner: Shut down the tractor.

  • Page 9: Tractor Mounting

    4. 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.

  • Page 10: Wire Rope Unwinding

    5. 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.

  • Page 11: Winch Controler

    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.

  • Page 12: The Smart 3In1 Function

    7. The SMART 3in1 / TERRA 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. Operation mode Classic mode SMART 3in1...

  • Page 13: Limit Switch

    Figure 8a Before switching off the SMART 3in1 function, turn of the tractor's engine and disconnect the power supply to the winch. Remove the protection on the winch (1, Figure 8a). Loosen the screws on the electric box (2). Move the switch 1(TERRA), 2(SMART 3in1) on the switch panel to position OFF. Close the box and tighten the screws (2).

  • Page 14: Settings

    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.

  • Page 15: Break

    3. Break At the end of pulling, the differential brake automatically engages. The brake is factory set to the braking force, which is 25% higher than the rated pulling force of the winch. As the braking padding is wearing down, the braking force is changing and you have to reset it periodically.

  • Page 16: Drive Chain Tensioning

    4. 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 or once every year. Tensioning is done according to the following procedure (figure 12)! First, disengage the PTO shaft and turn off the engine.

  • Page 17: Operation

    6. Operation The device begins unwinding 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 unreeling 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.
  • Page 18 Diameter of the wire rope During the construction of the wire rope, 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 45Hpro...

  • Page 19: Adjusting The Unwinding Speed

    7. 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: To increase the unwinding speed, rotate the valve (5, Figure 12b) in the counter-clockwise direction.

  • Page 20: Maintenance

    MAINTENANCE 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.

  • Page 21: Control Of Hydraulic Oil

    1. Control of hydraulic oil Oil level in the tank needs to be controlled occasionally. Oil level in the tank is 1,9 liters. For hydraulic system, oil for hydraulic systems ISO 32 is used. In summer months, when the ambient temperature surpasses 25 °C, oil ISO 46 needs to be used. First oil change needs to be done after 1000 hours of operation.
