5.1.4 Body injury hazard
Do not operate a machine with a hydraulic oil or air leak. An air leak or hydraulic leak can penetrate
and/or burn skin. During or after a period of running of the hydraulic system, the parts may produce
high surface temperature, and improper contact will cause burn to skin. Overhauling or adjusting any
part of hydraulic system can cause serious injuries. Only trained maintenance personnel are allowed to
repair or adjust the hydraulic system.
Suggestion: access by the operator is only advised when performing a pre-operation inspection. All
compartments must remain closed and secured during operation.
