Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor or gangrene may occur. 30. Before disconnecting or performing any work on the hydraulic system, all pressure in system must be relieved by stopping engine and lowering cutting units and attachments to the ground. 31. To reduce potential fire hazard, keep engine area free of excessive grease, grass, leaves and dirt. Do not use flammable solvents for cleaning parts. Do not use diesel fuel, kerosene or gasoline. 32.
