The following instruction manual describes the loading arm delivered by EMCO 
WHEATON. It does not describe the loading system and does not include fittings 
and devices which are not part of the loading arm.

helping to ensure safety and functionality. 

Follow the instructions of this manual in all details. It does not release you from

manner.
