OPERATION
HYDRAULIC LINE INSPECTION
¾Check for hydraulic leaks along hoses, cylinders and fittings. IMPORTANT: DO NOT use your hands to check for oil leaks. Use a piece of heavy paper or cardboard to check for hydraulic oil leaks.
¾Inspect the condition of the valve weldment.
¾Ensure fitting are properly connected
¾Inspect condition of nylon bushings.
DANGER! Do not operate this Equipment with hydraulic oil leaking. Oil is expensive and its presence could present a hazard. Do not check for leaks with your hand! Use a piece of heavy paper or cardboard. High- pressure oil streams from breaks in the line could penetrate the skin and cause tissue damage including gangrene. If oil does penetrate the skin, have the injury treated immediately by a physician knowledgeable and skilled in this procedure.
HYDRAULIC PUMP/OIL RESERVOIR
¾Check oil reservoir level and oil condition. (Add specific type oil if low)
¾Change hydraulic oil filter and hydraulic oil according to maintenance schedule.
¾Ensure there are no oil leaks and fittings are properly connected.
¾Inspect overall condition of hydraulic pump.
¾Inspect pump driveshaft.
Check the fluid level in the Hydraulic Tank on the Tractor, and add oil if required. As the air has been forced out of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the volume of oil. Maintain the oil level within the sight gauge located on the side of the reservoir. Never fill the tank above the sight gauge to allow for the expansion of the oil. The tank maintains pressure after the mower has been run. Stand off to one side when removing the breather cap element to prevent possible injury. To relieve pressure remove the breather cap element and depress the spring loaded pressure valve to release any excess air.
WARNING!
WARNING!
Attention: Oil Filter Cap is also the Pressure Relief Cap.
Remove cap slowly to relieve pressure before removing cap completely. Stay clear to prevent being scalded with hot oil that may spray out of the tank that is still pressurized and may cause serious injury to eyes, face, and exposed skin.
Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and hose connections. Relieve hydraulic pressure before performing maintenance or repairs. Use gloves and eye protection when servicing hot components. Contact with a hot surface or fluid can cause serious injury from burns or scalding.
