(Note: Some disassemblymay be required.)• Never use a hook whose throat opening has beenincreased, or whose tip has been bent more than 10degrees out of plane from the hook body, or is in any otherway distorted or bent. note: a latch will not workproperly on a hook with a bent or worn tip.• Never use a hook that is worn beyond the limits shown inFigure 1.• Remove from service any hook with a crack, nick, or gouge.Hooks with a crack, nick or gouge shall be repaired bygrinding lengthwise, following the contour of the hook, providedthat the reduced dimension is within the limits shownin Figure 1.• Never repair, alter, rework, or reshape a hook by welding,heating, burning, or bending.• Never side load, back load, or tip load a hook.(See Figure 2)• Eye hooks, shank hooks and swivel hooks are designed tobe used with wire rope or chain. Efficiency of assembly maybe reduced when used with synthetic material.• Do not swivel the S-322 swivel hook while it is supportinga load.• The use of a latch may be mandatory by regulations orsafety codes; e.g., OSHA, MSHA, ANSI/ASME B30, Insurance,etc.• Always make sure the hook supports the load. (See Figure3) The latch must never support the load. (See Figure 4)• When placing two (2) sling legs in hook, make sure theangle from the vertical to the outermost leg is not greaterthan 45 degrees, and the included angle between the legsdoes not exceed 90 degrees.* (See Figure 5)• See ANSI/ASME B30.10 "Hooks" for additional information.• see osHa Rule 1926.550(g) for personnelhoisting by cranes or derricks. a 319, 320 or322 hook with a Pl latch attached (when securedwith the bolt, nut and pin) may be usedfor lifting personnel.• Use only if trained.• loads may disengage from hook if properprocedures are not followed.• a failing load may cause serious injury or death.• threads may corrode and/or strip and dropthe load.• Hook must always support the load. the loadmust never be supported by the latch.• never apply more force than the hook'sassigned Working load limit (Wll) rating.• Read and understand these instructionsbefore using hook.zone b45°60°zone a!45°2/3zone cWARNINGZONE A: REPAIR NOT REQUIREDZONE B: 10% OF ORIGINAL DIMENSIONZONE C: 5% OF ORIGINAL DIMENSIONZONE D: SEE MINIMUM THREAD SIZEfigure 1side load back load tip loadWRonGzone bfigure 245°45°zone azone c2/360° zone D*For two legged slings with angles greater than 90°, use an intermediatelink such as a master link or bolt type shackle to collect the legs of theslings. The intermediate link can then be placed over the hook to providean in-line load on the hook. This approach must also be used when usingslings with three or more legs.RIGHtWRonGfigure 3 figure 4 figure 5HEADQUARTERS: 55 James E.
