INSTALLATION:
WARNING
Death or serious injury could occur if unauthorized or unnecessary personnel are in the hoisting
area. Permit only personnel actually engaged in the hoisting operation to be near the unit and
hoisting equipment. All instructions for the hoisting operations must come from one authorized
person.
Injury to personnel or damage to equipment could occur from improper hoisting. Hoist the load
slowly to avoid tearing out lifting bail assembly, slipping slings, or load shift. Do not jerk the load
or swing it from side-to-side when hoisting. This places additional stress on hoisting components
which can cause failure and loss of load. Be sure hoisting equipment is on solid footing and is
suitable for the size of the load. Watch boom angle and overhead clearance when hoisting.

Secure sling to the four upper corners of frame (3). Secure hoist to the sling above the center of the frame.

Lift the engine frame (3) and carefully lower it onto the skid, making sure it does not catch on or damage engine
or pump components.
