A standard 1/2" drive ratchet may be used to drive this wrench. Figures 1 and 2 show • sequentially the insertion of the wrench.First the wrench, with its jaws above the sprinkler deflector, is moved • laterally until centered with the cup. Then raise the • wrench inside of the cup until its jaws engage the sprinkler's square wrenching pads (Fig. 3). To remove the wrench,follow this procedure in reverse order. Care should be taken to avoid striking the deflector, with the wrench. • 5.
