WARNING
Hydraulic system pressure can exceed 3,000 psi (20 684 kPa). A high-pressure hydraulic
system can pierce a body. Ensure engine if OFF prior to disconnecting hydraulic hoses. Failure
to comply may result in injury or death to personnel.
Never disconnect any high-pressure hydraulic hose, line or component without first dropping
pressure to zero. Failure to comply may result in injury or death to personnel.
Wear proper eye protection when working with or performing checks on high-pressure hydraulic
systems. Failure to comply may result in injury or death to personnel.
CAUTION
Do not let cable end run into heavy-duty winch while reeling IN, or damage to equipment
will result.

WARNING
Excessive noise levels are present any time the heavy-duty winch, crane, or retrieval system
