tainer through the pressure hose. Make sure the engine is
at idle when performing this procedure. When the hydraulic
reservoir is empty turn the engine off immediately.
• Allow the fluid to sit long enough for the water to settle to
the bottom of the container. Slowly pour the fluid back into
the hydraulic tank, avoiding the water at the bottom of the
container.
• Each day, check hydraulic lines and fittings for leaks,
kinks, etc. Do not use your hand to perform this check.
