High pressure hydraulics [oil under 3675 psi (25,339 kPa) pressure] operate this equipment. Refer to

vehicle operator and maintenance manuals for hydraulic oil pressure. Never disconnect any hydraulic

line or fitting without first dropping pressure to zero. Failure to comply may result in injury to

personnel.

Fuel and oil are slippery and can cause falls. To avoid injury, wipe up spilled fuel or oil with rags.
