  • Page 52: Mounting And Connection Of The Machine (I)

    Assembly on different types of vehicles with different tool carriers is broadly the same procedure, but always investigate the procedure for the combination of machines used on your own. Common to all GreenTec attachment tools is that these are mounted either by bolting on to the standard attachment, or via mechanical quick-release.

  • Page 53: 5.4.3.1) Mounting And Connection Of Lrs 2002 Quadsaw On A Tool Carrier

    3. The adapter bracket of the tool carrier is slowly moved to the adapter bracket of the attachment tool and the 2 machines are (PICTURE) carefully hooked together: Table 29 – Mounting and connection of LRS 2002 Quadsaw on tool carrier (1/3)
  • Page 54 The oil motor on the attachment tool needs a minimum return line pressure to ensure correct working conditions. GreenTec's machines run with an open hydraulic circuit that includes a pumping station, engine, and oil tank. One of the advantages of an open circuit is greater heat reduction compared to a closed circuit.
  • Page 55 The drain pressure must never exceed the return pressure on the machine! A higher back pressure than permitted on the drain connection results in serious damage to the oil motor and the warranty for this is void! The drain connection must therefore always be routed by itself as a pressureless tank connection and must never be connected to the return connection! Always remember to turn the locks on the hydraulic quick couplings to avoid accidental disconnection when a branch sweeps over the quick couplings! If...

  • Page 58: Preparing The Machine For Use

    5.5.2) Training of machine operators before use The GreenTec attachment tool may only be used mounted with tool carriers approved by GreenTec, and on an approved vehicle as a single unit. The operator of a vehicle with a tool carrier and attachment tool mounted must therefore both review and understand the instruction material for the attachment tool as well as the instruction material for the tool carrier and the vehicle used, before putting the machine into use.

  • Page 59: 3) Stability (O)

    5.5.3) Stability (o) When driving with the attachment tool, the operator must always be aware that the machine's centre of gravity shifts during work: After mounting and connection it must always be ensured that the complete vehicle is stable enough to be able to carry the tool carrier with the attachment tool attached.

  • Page 60: 5.5.3.2) Stability Can Be Increased By

    4. Assessment is made in each individual situation, and it is the full responsibility of the operator and operators to ensure that the vehicle does not overturn or tip over. If the vehicle and tool carrier are stable, the attachment tool can be moved up step-by-step. 5.

  • Page 61: 4) Initial Start-Up And Commissioning

    5.5.4) Initial start-up and commissioning The initial start-up of the machine for use, like the initial mounting and connection of the machine, should always be carried out by the dealer with the necessary knowledge and experience. When the attachment tool is to be used for the first time with an approved tool carrier on the vehicle, it is recommended to always go through the steps below to ensure an optimal and safe first start-up of your machine: PROCEDURES FOR INITIAL START-UP AND COMMISSIONING:...

  • Page 64: Transport Of Attachment Tools On A Vehicle (P)

    Common to all transport positions for GreenTec's attachment tools mounted on approved tool carriers, • is that the construction of the arm system ensures that the attachment tool always point towards the vehicle, without being a danger or a nuisance to either the driver, pedestrians or other road users.

  • Page 65: 3) Start Of Attachment Tool

    5.6.3) Start of attachment tool The attachment tool can be started as soon as it is mounted correctly, and the tool carrier is in the working position. See sections: Instructions for mounting, connection and disconnection (j) – page 38-47 + Preparing the machine for use –...

  • Page 66: 4) Stop Of Attachment Tool

    5.6.4) Stop of attachment tool The attachment tool must always be stopped at the lowest oil supply / RPMs from the tool carrier: 1. The attachment tool is stopped by first running it down to a low oil flow / low RPM on the vehicle! (Always refer to and follow the vehicle instructions used as these will vary from vehicle to vehicle!) 2.

    See section: Driving instructions – page 59-61. The settings and adjustment options for the LRS 2002 Quadsaw are described below: 5.6.5.1) Adjusting the branch guides: The saw blades rotate against the surface of the earth and saw/cut in a downward direction.

  • Page 68: 5.6.5.2) Setting The Cutting Angle

    Setting the cutting angle on the LRS 2002 Quadsaw The LRS 2002 Quadsaw is recommended to be angled vertically with an offset of approximately 250 mm (9.84”) between the upper and lower saw blades. This ensures that the Quadsaw meets the material in the best possible way and that the optimal cutting result is achieved.

  • Page 69: Driving Instructions

    5.6.6) Driving instructions The machinery must always be operated and used in the most appropriate way, so that you achieve the best possible result and the greatest safety during use. The machinery must at all times be used within the limitations of the machine's safety instructions, intended use and area of application, so that it is always used for its intended purpose.

  • Page 74: Instructions For Safe Maintenance And Adjustment (S)

    GreenTec recommends moving machines and attachment tools around on their supplied support devices/stands, or transport pallets (EU standard) if support devices are not available. If machines are to be moved, always use a forklift or pallet lifter. Always check the weight of your GreenTec machine under the machine specifications.

  • Page 75: Daily And Routine Inspections (E)

    6.2) Daily and routine inspections (e) Before starting up a new machine, a daily inspection is carried out before starting up, and again already after 3-5 operating hours. After this, a daily inspection after using the machine is sufficient, combined with a six-monthly inspection of the machine! (Every 6 months) At the beginning of the machine's service life, extra attention should be paid to the tightening of bolts, shielding and any belt tension on attachment tools.

  • Page 79: Hydraulic Hoses

    Check all hydraulic hoses and fittings daily. Any damage or leakage must be repaired immediately. Hoses with damage/defects must be replaced. GreenTec's hydraulic systems work at a very high pressure: from approx. 200 bar up to 320 bar (2900 – 4621 psi) Use only original hoses. A burst hose can be very dangerous! When replacing hydraulic hoses, avoid twisting hoses and fittings.

  • Page 80: Bearings, Shafts, Rivets, And Bushings

    Bearings etc. most often fail as a result of errors that could have been avoided: incorrect assembly after replacement, handling or lubrication, ingress of foreign bodies or abnormal heat generation. The bearings on the LRS 2002 Quadsaw have rubber seals and can therefore be considered "maintenance- free", as they are all sealed and do not require relubrication.

  • Page 81: Checking And Adjusting Belt Tension

    6.6) Checking and adjusting belt tension The belt tension on the machine is decisive for the overall function and performance of the attachment tool and must always be checked and approved before use. Great care must be taken when working with the machine's belt drive, as there is a risk of fingers and hands being pinched by the drive belt and pulleys! 6.6.1)
