3. Safety Precaution for Fly-Jib Operation WARNING ・ fly-jib kit under operation should be fixed by four bolts and three fix pins. Prior to start operation, always assure that all of three pins are set in positions correctly, as well as that four sets of bolts and nuts are driven tightly. In addition, ensure that snap retainers are correctly inserted to three fix pins to prevent them missing. ・When stowed, fly-jib is fitted to main-boom with two stowage pins. Prior to let the crane body travel, make sure that two pins are properly secured. Also, ensure that snap retainers are correctly inserted to these two pins to prevent them missing. ・ Always check correct function of over hoist detector before starting fly-jib operation. ・ Always fully extend two stages of Fly-Jib in use, because moment limiter's fly-jib mode calculates and indicates working radius and lifting height on basis of full length. ・Always make outriggers contact to the ground for fly-jib operation. (Outriggers position may be minimum extended.) ・ Never pick and carry by fly-jib. It is a hazardous operation. Please refer to MC-405C Operation Manual (separate volume) for general precautions for safety operations.
