To avoid serious injury or death:
Hydraulic fluid under high pressure can penetrate the skin

and/or eyes causing a serious injury. Wear protective gloves

and safety glasses or goggles when working with hydraulic

systems. Use a piece of cardboard or wood rather than hands

when searching for leaks. A doctor familiar with this type of

injury must treat the injury within a few hours or gangrene

may result. DO NOT DELAY.

shown. Install two 90 degree elbows (#4) into the

elbow at cylinder base end and tighten.

3. Screw 123" long hydraulic hose (#7) into the rear

elbow at cylinder rod end and tighten.

4. Thread adapter fittings (#6) onto the other end of the

hydraulic hoses and tighten.
