General Safety Instructions
Well ventilated area
Insure proper lifting methods and procedures
REMOVAL:
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.
Because this part weighs more than 2250 lbs (1020 kg), a hoist will be required to lift the pump to
avoid personal injury.
1.
Position a suitable lifting device and slings over pump assembly (1). Attach slings around assembly and put
tension on slings. Make sure pump assembly is properly supported.
2.
Remove four bolts (2) securing pump (1) to skid (3).
3.
Lift puma straight up from skid and lower onto blocks on a stable level work platform.
