Clean and check the lights:
In case of fault replace the lamp. If the lamp keeps on braking repeatedly, find out the case
of the matter.
•
Check electrical connectors:
Clean them of dirt and dust.
•
Check wires insulation:
Check wire insulation, wire joints and protection of insulation against rubbing during jolting
and contacting the trailer parts. Protect the wires from oil and fuel, which ruin insulation. Wipe
dirty wires.
NB: Join and disjoin plug connectors only with dead circuits.

Maintenance of the brake system
The trailer is manufactured with a hydraulically functioned brake system. Air brake system
with negative or positive action is optional.
Control the brakes regularly. Test the brakes at least once per week while trailer is
working.
See to it that no lubricant penetrates into the brakes. Any lubricant, which has penetrated
the brake, causes greasing of the disks, thereby reducing friction between their working surfaces. A
poor operation of the brakes is the result of such happening. In such a case dismantle the brake,
eliminate the oil leakage, wash the greasy disks with gasoline and let them dry out.
Control always the brake control linkage after the drum being dismantled, adjust if needed.
For adjusting the brakes you need to lift up the bogie-frame from the ground and adjust the
brake levers. You do this by spinning the wheel while adjusting. The brakes are correctly adjusted
when they spin freely without any scraping noises from the wheel. After all kinds of adjusting in
regards to the brakes, always carry out a practical brake test before driving away.
If the brakes seems to work grainy, found the brakes, pull the trailer maintaining low speed
for a couple of hundred meters, try again through braking the vehicle while driving in a normal
speed. Keep on reiterate until the brakes functional normally. If necessary contact our service
department!
BIGAB models 7 – 10, 8 – 12 and 10 – 14 – the brake show distance to the drum needs to be
adjusted through loosening and by doing so adjusting the brake control linkage.
BIGAB models 12 – 15, 15 – 19 and 20 – 24 – the brake show distance to the drum on the brake
cylinder needs to be adjusted through loosening or vice versa tightening the adaptable screw on the
brake.

condition of the threaded joints and timely tightening there of and in observance of the rules for use
and maintenance of tires.
•
Check the threaded joints.
•
Check the pressure of air in the tires.
