2.4 Dangerous Situations

Please find below a list of the most dangerous situations and the actions that must be taken
upon identification of the situations
2.4.1

High Pressure Hydraulic Fluid Leak

Following the leak or rupture of a hose, a jet of hydraulic oil under
pressure can penetrate the skin causing severe injuries. To avoid this
risk, the operator must de-pressurise all circuits from the tractor. The
tractor manual will instruct how to do this.
When working in close proximity to the machine, consider de-
pressurising circuits unless it is necessary for them to remain
pressurised.
If you suspect a leak, use a piece of cardboard to locate the leak.
Always wear protective clothing (gloves, full length shirt etc) and eye
protection.
If an accident occurs, call the local emergency services.
2.4.2

Accumulator

The hydraulic accumulator which powers the cushion hitch cylinder
sustains pressure in the system even when the tractor hydraulics are
disconnected. See the section in the manual covering maintenance and
repair procedures.
2.4.3

Storage and disposal of waste

Be careful of the environment; consider using appropriate containers
to recover the liquid and used materials. Make sure they are stored and
removed in accordance with local laws and regulations.
2.4.4

Working near hydraulic circuits

Take extreme care when welding, brazing or using an open flame near
hydraulic circuits. The pressurised fluid escaping through a leak can
ignite and cause serious burns and potentially be fatal.
