Some attachments are hydraulically powered. The
following paragraphs describe how to connect and
disconnect the hydraulic hoses safely.

Hydraulic Pressure
Hydraulic fluid at system pressure can injure you.
Before connecting or removing any hydraulic hose,
residual hydraulic pressure trapped in the service
hose line must be vented. Make sure the hose service
line has been vented before connecting or removing
hoses. Make sure the engine cannot be started while
the hoses are open.

This will release any hydraulic pressure trapped in the
hoses.
3 Connect the hoses. K

Fluid Under Pressure
Fine jets of fluid at high pressure can penetrate the
skin. Keep face and hands well clear of fluid under
pressure and wear protective glasses. Hold a piece of
cardboard close to suspected leaks and then inspect
the cardboard for signs of fluid. If fluid penetrates your
skin, get medical help immediately.
