NOTE
During extension, maintain slack in hoist sling as top beams are raised.
At front and rear, operate hydraulic control valve to extend hydraulic lift cylinders (5) until axle assembly (11) is
approximately horizontal. Extend hydraulic positioning cylinders (7) until bottom beams (10) rest on the ground
(see paragraph 2-21). Keep top beams (6) and bottom beams vertical as hydraulic cylinders are extended.
Repeat alternating extension of hydraulic lift cylinders (5) and hydraulic positioning cylinders (7), maintaining
top and bottom beams (6 and 10) vertical. Stop when top beam vertical tubes (8) have extended approximately
49 in. (124 cm) and hydraulic positioning cylinder limit lines (9) are visible.
NOTE
During retraction, maintain slack In hoist sling as top beams are lowered.
At front and rear, operate hydraulic control valves to retract hydraulic lift cylinders (5) until bottom beams (10)
rest on the ground. Retract hydraulic positioning cylinders (7) until axle assembly (11) is approximately
horizontal (see paragraph 2-21). Keep top beams (6) and bottom beams vertical as cylinders are retracted.
Repeat alternating retraction of hydraulic lift cylinders (5) and hydraulic positioning cylinders (7) maintaining
top and bottom beams (6 and 10) vertical. Stop when hydraulic cylinders are fully retracted.
At front and rear, shut down engine (see paragraph 2-20).
Fill hydraulic reservoirs to top line on dipstick (see paragraph 3-7).
At front and rear, start engine (see paragraph 2-20).
