  • Page 23: Determining The Gradient Of The Slope

    Determining the gradient of the slope Measure the slope with a digital clinometer, or do as follows: Take a water level, a straight piece of wood (at least 1 m long), and a pocket tape measure. Place the wood on the gradient. Put the water level on the lower edge of the stick and lift the stick until it is in a horizontal position.

  • Page 24: Fixing Nuts For The Tracks' Rear Sprocket

    Fixing nuts for the tracks’ rear sprocket It is important to check the tightening of nuts on the rear sprocket (bigger track wheel) 2 days after commissioning the access platform. When driving with a new machine, the parts in the track system adapt to each other and “find their place”.
  • Page 25 Avoid repeated sharp turns. o By making wider and more gentle turns, you can avoid unnecessary wear of the tracks and/or tracks jumping off the sprockets. Avoid driving with one track on a level surface and one track on a gradient. o Always drive on an even surface.

  • Page 26: Operation Of The Outriggers

    OPERATION OF THE OUTRIGGERS The outriggers are placed in the support position as follows: 1. Turn the ‘mode selection’ switch to the outrigger operation position. 2. Ensure that the four red outrigger pressure signal lights are on and that the green light does not light up! If the red outrigger pressure lights are not on, push all the outrigger levers up.

  • Page 27: Use Of The Booms

  • Page 28: Emergency Lowering And Emergency Use

    EMERGENCY LOWERING AND EMERGENCY USE Electric lower controls If the operating power supply cuts off (fuel running out, power cut or damage to the extension cord), the booms can be lowered as follows: 1. Emergency lowering switches are located on the platform control panel and in the control system connection box.

  • Page 29: Stopping Operation

    STOPPING OPERATION After concluding operation: 1. Lower the booms down to transport position. 2. Lift the outriggers completely up to transport position. 3. Turn the ignition key to the ‘0’ position and take it with you. 4. Remove safety harnesses from the platform and take them with you (harnesses must be kept in their place and in their box/package).

  • Page 30: Transport Of The Access Platform

    TRANSPORT OF THE ACCESS PLATFORM The chassis and outriggers are equipped with lifting and binding points which are indicated with symbols. The machine may only be secured for transport from these binding points. The machine must always be lifted from the designated lifting points. When lifting, it is advisable to use a lifting beam in order to prevent the outriggers from getting damaged.
  • Page 31 There is an automatic hydraulic brake in the rear axle that engages automatically when the combustion engine/electric motor is not running. If the machine is transported on a trailer, a lorry or a similar vehicle, it must be secured carefully. There are four binding points marked on the corners of the chassis which make it easy to secure the machine.
