In Case of Emergency
Bucket-Inoperation Is proper unit mode selected? Are outrigger interlocks satisfied? Emergency lowering Lower controls Manual lowering valve D/C pump Use only for emergency situations
Unit Electrical Contact What if unit contacts energized lines?! Move away from conductor/lines if possible Stay in the bucket or on bed truck If egress from bed of truck is absolutely necessary, jump clear and shuffle away from truck No one from ground should contact the equipment Contact supervisor and Fleet department immediately
