shaft expander arms must make the same movement and braking process must take place
simultaneously on all wheels. After the brake is released, expander arms may not be
supported on any structural elements, because insufficient withdrawal of a piston ram may
cause abrasion of brake shoes in drum and result in overheating trailer brakes.
Checking and adjustment of main brake:
•
every 12 months,
•
if needed.
Difference in braking force may not be greater than 30%, considering that 100% constitutes
greater force.
Brake repairs, changes of brake linings etc. may be only undertaken in authorised service
points. Making unauthorised repairs and modifications by the user voids the guarantee.
Among the service operations which may be performed by the trailer user there is only brake
adjustment by changing the setting of expander arms.
5.2.3 OPERATION NO. 3 - DRAINING WATER FROM THE AIR TANK

The compressed air in the tank causes the removal of water to the exterior.
After release valve pin should automatically close and stop airflow from tank.
In the event, that the valve pin resists returning to its setting, then the whole
drain valve must be unscrewed and cleaned, or replaced (if it is damaged).
Draining water from air tank:
•
