DANGER

CRUSHING HAZARD

• Death or serious injury could result

  from being crushed by moving machinery

  or by improper set-up on outriggers.

• Ensure all pins and floats are 

  properly installed and the outrigger 

  beams are properly extended before

  lifting on outriggers.

• Stand clear while outriggers are being

  extended or retracted.
