10. Stowing and Transporting ■ Towing ■ Lifting The Snorkelift AB46J has not been designed to be towed. An AB46J can be safely lifted. DO NOT tow an AB46J. DANGER A runaway AB46J can cause Death or Serious Injury. If you have to move an AB46J down a grade, chain a braking vehicle to the “up hill “ end of the AB46J. CAUTION However, to prevent any damage to the AB46J or injury to personnel, only a trained qualified service technician should perform lifting.
11. Options ■ Air line to platform The input to the air line is on the lower rear of the turntable. The outlet is on the platform mounting frame. The maximum safe working pressure for the air line is 250 psi (1725 kPa). If the BumpGard comes into contact with a stationary object, the BumpGard moves and one or both of the light beams is broken. A dark switch removes control from the platform control box, immediately stopping all platform movement.
11. Options ■ Motion Warning Alarm The motion warning alarm emits a very loud sound (...beep...beep...beep...), at ground level, when the Drive/Steer controller is in FORWARD or REVERSE or when one or more booms are in motion. This alarm alerts people on the ground that the AB46J is moving. ■ Platform Swinging Gate The optional platform swinging gate is designed to automatically close after you enter or leave the platform. It helps prevent people from falling off the platform.
12. Fire Fighting and Chemical Containment ■ Hazardous components ☞ Waste disposal method An AB46J contains the following materials and objects that potentially could become significant fire or environmental hazards during it's lifetime: 1. Battery, lead/acid 2. Foam in tires 3.
