ATTACHING DOLLY SET TO SHELTER (Cont).
(12) Remove two handles (20) from dolly set toolbox and install handle (20) in each hydraulic pump
(18 and 21). Operate each hydraulic pump (18 or 21) to slightly pressurize hydraulic system.
(13) Release four support strut clamps (23) by rotating clamp handles counterclockwise.
For the M832 (SN J089-001 thru 159 and J017-180 thru 350), skip step 14 and
perform step 15. Make sure dolly halves are lowered together.
(14) Slowly rotate release valve levers (17) to RELEASE position to lower suspension bars (25) to
(15) Slowly open control valves (16) on front and rear dollies by rotating counterclockwise.
For the M832 (SN J089-001 thru 159 and J017-160 thru 350), support struts
must buckle during lowering. If they do not, close both control valves and pull
outward on struts until they begin to buckle. Open control valves and continue
lowering dolly halves. When halves are completely lowered, open control
valves fully counterclockwise.
