Chapter 1 – Introduction Aerial Platform Features The aerial platform is a boom-supported elevating work platform used to raise personnel, their tools, and material to the workstation. The aerial platform has been designed for use on hard surface floors such as concrete. The booms are raised and lowered with hydraulic cylinders. Electric motors on the drive wheels provide power to move the aerial platform.
Chapter 1 – Introduction The operator bears ultimate responsibility for following all manufacturer’s instructions and warnings, regulations and safety rules of their employer and/or any state or federal law. Maintenance Every person who maintains, inspects, tests, or repairs the aerial platform must be qualified to do so. Following the daily prestart inspection in this Operator’s Manual will help keep the aerial platform in optimum working condition.

Chapter 3 – Safety Knowledge of the information in this manual, and proper training, provide a basis for safely operating the aerial platform. Know the location of all controls and how they operate to act quickly and responsibly in an emergency. Minimum Safe Approach Distance Minimum safe approach distances to energized power lines and their associated parts must be observed while operating the aerial platform. Safety devices reduce the likelihood of an accident.
Chapter 3 – Safety Prestart Inspection Perform a prestart inspection before each shift as described in Chapter 8. Do not use the aerial platform on the job unless you are trained and authorized to do so. Work Place Inspection and Practices Do not use the aerial platform as a ground connection when welding. • The welding ground clamp must be attached to the same structure that is being welded. Danger Pinch points may exist between moving components.
Chapter 3 – Safety Properly stow the aerial platform and secure it against unauthorized operation at the end of each work day, before transporting, or if it is left unattended. Do not operate the aerial platform from trucks, trailers, railway cars, floating vessels, scaffolds, or similar equipment unless the application is approved in writing by Snorkel.
Chapter 3 – Safety Danger Hydraulic fluid escaping under pressure can have enough force to inject fluid into the flesh. Serious infection or reaction will result if medical treatment is not given immediately. In case of injury by escaping hydraulic fluid, seek medical attention at once. Placards and Decals The aerial platform is equipped with placards and decals that provide instruction for operation and accident prevention.
Chapter 4 – Safety Devices This aerial work platform is manufactured with safety devices, placards, and decals to reduce the likelihood of an accident. Emergency Stop Button • For the safety of all personnel, do not disable, modify, or ignore any safety device. • Safety devices are included in the daily prestart inspection.
