Stay clear ofscreed during screed operations.Failure to do so may result in deathor serious injury.NOTECribbing is used under the screedonly as a safety precaution. Do notlower the screed onto the cribbing.Cribbing may have to berepositioned during alignmentprocedure to allow for placement ofstraightedge and to viewmeasurement points.NOTEIt may be necessary to use pry bar toraise lift bracket (23) to relievepressure on hex nuts (24 or 25) toallow for ease in makingadjustments.e.Using crowfoot wrench, loosen hex nuts(24) and adjust hex nuts (24 or 25) at frontor rear of lift bracket (23) to align extensionscreed plate angle resulting in an equalreading at B-B and C-C. If required, adjustsetting in step d. Continue adjusting hexnuts (24 and 25) and screed heightadjustment knobs to obtain 0.125 to 0.19in. (3,2 to 4,8 mm) height differencebetween leading edge and trailing edge ofextension screed plate.f.Tighten hex nuts (24 and 25) withoutchanging angle of extension screed plate.g.Adjust extension screed height adjustmentto level trailing edge of extension screedplates with trailing edge of main screedplate at points B-B and C-C.h.Measure leading edge of extension screedmeasurements B-B and C-C for 0.13 to0.19 (3,2 to 4,8 mm) height differencebetween leading edge of extension screedplates and trailing edge of screed plates.Repeat steps c through i as needed.WARNINGThread locking compound can causeeye damage. Wear safetygoggles/glasses when using. Avoidcontact with eyes. If compoundcontacts eyes, flush eyes with waterand get immediate medical attention.i.Loosen hex nuts (24) enough to applythread locking compound. Tighten hexnuts (24) to 37 lb-ft (50 N•m).
