Ignoring this can entail a danger to life.
  • Page 15 20-24 Figure 21. Risk of slipping There is a risk of slipping as the surfaces of the trailer can be slippery due to precipitation in combination with pre-existing oil and/or clay on the surface. The ground around the trailer can also become slippery, as the tyres can tear up the surface and expose clay and soil.

    20-24 4. SAFETY INSTRUCTIONS IMPORTANT: READ AND UNDERSTAND THE USER MANUAL CAREFULLY BEFORE USING THE DEVICE. CONSULT THE USER MANUAL TO SOLVE YOUR PROBLEMS. THE DEVICE HAS AN IDENTIFICATION LABEL ON IT. BEFORE USING THE TRAILER, ENSURE THAT FACTORY SETTINGS HAVE NOT CHANGED AND THAT NO PARTS HAVE LOOSEN DURING TRANSPORTATION.
  • Page 31 20-24 During maintenance: • Be sure that the trailer is standing on a flat surface. • Be sure that the trailer can’t move. • When lubrication or servicing the trailer, turn off the vehicle engine. • Be sure that the trailer can’t slip when using support leg, jack or similar equipment.
  • Page 32: Working At Extreme Conditions

    • Recommended load placement - symmetrical. 4.2. WORKING AT EXTREME CONDITIONS Recommended working temperature range for a Bigab trailer is –30°C up to +40°C. Note that working at low temperatures accelerates hydraulic gaskets wearing and increases hydraulic hoses exposure to damages and steel constructions exposure to brittle fracture.
  • Page 33 20-24 IF YOU ARE INSIDE THE MACHINE Get out of it by JUMPING. Avoid touching any conducting parts. Do not make yourself a wire through which electricity may flow. Get away from the machine by JUMPING so that both feet do not touch the ground at the same time. Electric field at ground can cause fatal voltage between legs.
