  • Page 20: Safety Precautions: Operation

    Operating, servicing, or adjusting a setting without fully understanding how the felling head works can have serious implications on safety. Consequently, you should ensure all machine operators read and understand the FL85 Operators’ Manual and Component Technical Manual. If either manual is missing or damaged, replace it immediately.

  • Page 21: Avoid Work Site Hazards

    Safety precautions: Operation Avoid work site hazards Avoid contact with gas lines, buried cables, and water lines. Before starting work, contact utility line location services to identify all underground utilities. Prepare the work site properly; clear away any debris that may move unexpectedly if it is run over. Avoid operating the machine near structures or objects that could fall onto the machine.

  • Page 22: Avoid High-Pressure Oils

    Safety precautions: Operation Avoid high-pressure oils This machine operates using a high-pressure hydraulic system. If oil escapes while under pressure, it can penetrate your skin, causing serious injury. Never search for leaks with your hands: use a piece of cardboard to locate the source of any escaping oil. Before disconnecting any lines and/or working on the hydraulic system, ensure you stop the engine and relieve the system pressure.

  • Page 23: Charge The Air Tank

    Safety precautions: Operation Charge the air tank If air escapes from a pressurised/compressed air system, it can cause serious injury. Avoid exposing the air tank to extreme heat, as this may burst the tank, accidentally cutting pressurised lines. Do not weld or use a torch near a pressurised air tank or line. Before you remove the air tank, ensure you first relieve pressure from the compressed air system.

  • Page 24: Safety Precautions: Service And Maintenance

    Safety precautions: Service and maintenance Preparing for service Before you start a service procedure, ensure you warn others of this work. You should also attach a “Do Not Operate” tag in an obvious place in the operator's station. Always park and prepare your machine for service or repair properly.

    Operation: Felling Large-diameter trees 2. Ensure you maintain full control of the felling head at When processing and/or felling large-diameter trees: all stages of felling and cutting. 1. The grapple arms must be able to fit around the butt 3. After you have made a felling-cut, and the tree is in a controlled fall, you can release the tree from the head.

  • Page 34: Basic Process

    Operation: Felling Basic process Felling Pay careful attention to the felling direction and presentation of the stem. Doing so will reduce breakage and will allow you to present a stem that has been appropriately delimbed, facilitating extraction and further processing. It is recommended you fell a tree against a standing tree by felling it just off centre to a standing tree.

  • Page 35: Select Felling

    Operation: Felling Select felling You should fell and stock-pile stems with the butts placed so as to facilitate the extraction machine’s access from the site pathway. This method is dependent upon the finished crop stocking levels. Select felling allows a reduction in the number of paths cut from a block, while providing access for extraction carriers.

  • Page 36: General Cut Process

    Operation: Felling General cut process 1. For smaller trees that only require a single cut, you may need to over-ride the felling head’s unlatching with the tilt-up button pushed during cutting. This will prevent the tree from being forced faster than the saw chain can cut.

  • Page 37: Main-Saw Process

    Operation: Felling Hillside felling If you are felling trees on a hillside, it may mean the cutting unit is exposed to dirt/duff on the uphill side of the tree(s). Ensure the head is positioned correctly (5), so the tip of the saw bar does not ‘foul’...

  • Page 38: Plantation Felling

    Operation: Felling Plantation felling Planation techniques: Plantation out row: Cut to length at the stump A path of stems approximately four metres (12-feet) wide is felled to provide the felling head and the forwarder access. Stems on both sides of the path are felled, and are stacked on either side, ready for harvesting, before being lifted by the forwarder for extraction.

  • Page 39: Double-Cut Technique

    Operation: Felling Double-cut technique CAUTION: While a number of factors can affect the felling control and direction of large or double-cut trees, uncontrolled felling can create a hazardous situation. To reduce the risk of this occurring, ensure you use work site planning and management methods when felling such trees.

  • Page 40: Quarter-Cut Technique

    Log loading 1. Open the grapple arms and pick up the appropriate logs. While the FL85’s arms are optimised for felling, shovel-logging, and bucking, you can also use it for 2. Swing and wrist the felling head to the desired location loading.
