AFTER USE - CONTINUED
Lowering Dolly Set and Container/Shelter - Continued
Slowly, in unison (all four crewmen), open the hydraulic pump release valves by turning valves (3)
counterclockwise to the REL (Release) position. This will lower all cylinders in unison ensuring that the strut
knee joint (7) is bending and is not locked straight.
Serious damage to dolly set can result if only one strut
knee joint is locked straight and lowering operation is
continued. Lowering operation should be stopped
immediately if strut knee joint remains locked straight.
Check for obstructions that could prevent strut knee joints from bending.
Ensure that strut knee joints (7) are bending. Stop operation immediately if strut knee joints are not bending
and are locked straight.
Lower all four sides of dolly set to ground in unison, ensuring that adapter arms (9) remain vertical (not tilted)
while lowering dolly sets until contact is made with the ground. Tilted adapter arms means that one side is
lowering faster or slower than the others. However, to correct this condition, open the valves (REL position)
on the pumps of the tilted adapter and close the valves (PUMP position) on the other. Activate hydraulic
pumps until adapters are in a vertical (straight) position.
Reduce pressure in all four air springs (10) to 10 PSI after contact is made with the ground.
