b. Fill hydraulic pump (25) with hydraulic fluid as required in accordance with manufacturer's specifications.
c. Connect hydraulic hose (24) to hydraulic ram (23).
d. Place hydraulic ram (23) on the ground with ram extender facing up.
e. Hold hydraulic pump (25) as high as possible without kinking hydraulic hose (24) or lifting ram (23) off the ground.
f. Operate hydraulic pump (25) until ram (23) is fully extended with approximately 3 inches (7.6 cm) of ram piston
showing.
g. Open relief valve on hydraulic pump (25) to allow hydraulic ram (23) to retract. Close relief valve on hydraulic
pump (25).
22.
Using two people, aline hydraulic ram (23), with hose connection on ram pointing upward, to extender (19).
Secure hydraulic ram (23) to extender (19) by installing two 3-inch long capscrews (26) and lockwashers (27).
