PREPARATION FOR USE - CONTINUED
The shelter payload is leveled by raising or lowering the four hydraulic cylinders independently as necessary. There are
two ways the shelter must be leveled: end-to- end and side-to-side.
To level shelter, close all hydraulic pump release valves (1) by moving valves clockwise to PUMP position.
Open all hydraulic cylinder valves.
Extend all hydraulic cylinders (2) by operating manual hydraulic pumps until all cylinders are extended (leave
pump control lever closed).
Remove the individual safety lockout pins (3) from struts (4) and free the individual mechanical struts.
Close all hydraulic cylinders by placing hydraulic pump release valve in PUMP position.
Turning the pump release valve too quickly will allow
the shelter to drop rapidly, causing possible damage
to equipment and/or personnel injuries. Stand clear
of the dolly set and shelter during lowering operation
To level the shelter end-to-end, SLOWLY open the hydraulic pump release valves for both cylinders to be
raised/lowered at the high end of the shelter by moving the associated hydraulic pump release valves to the
Slowly turn pump release valve back and forth between PUMP and RELEASE positions as required.
Gently lower shelter at high end until both ends of the shelter are at the same height (level).
To level the shelter side-to-side, decide which side of the shelter is higher.
Open the hydraulic cylinders, one on each dolly, on the cylinders on the high side of the shelter by placing
pump release valve to REL position.
Slowly turn pump release valves on the hydraulic pumps on the high side of the shelter back and forth
between PUMP and RELEASE positions as required.
