5.2.4.
Maintenance of the electrical components
The trailer is manufactured with 12V electrical system. Electrical system is
shown in chapter 3.4.
The wires to the electrical equipment are of different colors, which facilitate
the location of the wire leads connecting individual items of the electrical equipment.
Refer to the electrical diagram (figure 3.4) to ensure a correct subsequent
reconnection of the electrical units and also when checking the operation of the
equipments and individual electric circuits.
•
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.
5.2.5.
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.
