WORKING IN EXTREME CONDITIONS
Recommended working temperature range for a Bigab trailer is from –30°C up to +40°C. Note that
working at low temperatures accelerates hydraulic gaskets wear and increases hydraulic hoses exposure
to damages and steel constructions exposure to brittle fracture. When working at lower temperature
than recommended, lift lighter loads than usual.
Before starting to work in cold conditions let the oil circulate freely through the system a few minutes.
Slowly work every hydraulic function through several times so that gaskets become exible before they
receive full pressure.
At exceptionally warm conditions beware of hydraulic oils excessive heating. Too high oil temperature
(above +80°C) degrades the oil and can damage gaskets.
ACTING IN DANGEROUS SITUATIONS
If the trailer comes into contact with high voltage electric wires
comply with the following instructions:
If you are outside the machine
Do not attempt to get into the machine. Keep everybody away from the machines vicinity. Do not touch
any part of the machine.
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 ow. Get away from the machine by JUMPING so that both feet do not touch
the ground at the same time. The electrical eld of the ground can cause electrocution if both legs are
touching simultaneulsy (closing the circuit). You should be safe 20 meters away but this is of course a
questions of circumstances.
DISCONNECTING THE TRAILER
The oil can be very hot! Do not allow the hydraulic hoses to hang
down to the ground
• Park the trailer on a at, stable surface. Position a parking leg.
• Switch o the tractor’s hydraulic pump and power take-o. Release the remaining hydraulic
pressure.
• Disconnect the hydraulic hoses. Start with the pressure line rst, followed by the return lines
and nally any electrical contacts. Ensure that protective plugs are installed in the hose.
• Finish by disconnecting the trailer’s coupling device from the towing vehicle’s tow hook.
