manual abstract
Remove cap slowly to relieve pressure before removing cap completely. Stay clear to prevent scalded with hot oil that may spray out of the tank that is pressurized and may cause serious injury to eyes, face and exposed skin. HYDRAULIC PUMP/OIL RESERVOIR • Check oil reservoir level and oil condition. (Add specific type oil if low) • Change hydraulic oil filter and hydraulic oil according to maintenance schedule. • Ensure there are no oil leaks and fitting are properly connected • Inspect overall condition of hydraulic pump. • Inspect pump drive shaft. 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 resevoir. 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. OPS-B- 0024_H 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. (SG-34) OPERATION © 2010 Alamo Group Inc. OPERATION 2160 02/10 Operation Section 4-17 ROTARY HEAD INSPECTION • Inspect blades and blade bolts for looseness and excessive wear. Rotate to 90° to make for checking easier. Replace damaged, worn, and missing blades as complete sets to maintain rotary balance. • Ensure carrier hub nuts are tightened with the cotter pin inserted and spread. • Ensure rubber deflectors are in position and not damaged. Replace worn, broken, and missing sections immediately. • Ensure hydraulic lines are properly connected to the hydraulic motor. Check for hydraulic leaks along hoses and fittings. DO NOT use your hands to check for oil leaks. Use a piece of heavy paper or cardboard to check for hydraulic oil leaks. • Inspect the condition of deck skid shoes and hardware. OPS-B- 0025_A Do not put hands or feet under mower decks. Blade Contact can result in serious injury or even death. Stay away until all motion has stopped and the decks are securely blocked up.

OPERATION 2160 02/10 Operation Section 4-18 40 7.3 Cutting Component Inspection Inspect blade pan and blade assembly for the following: OPS-U-0031 OPERATION © 2010 Alamo Group Inc. OPERATION 2160 02/10 Operation Section 4-19 Operating the mower with loose blade hardware will damage the blade holder or blades and can result in blade breakage or blade fastener failure. Broken blades or bolts can be thrown out from under the mower for distances up to 300 feet. When the blades are replaced, the fastening hardware must be replaced. Check and retighten the blade hardware after the first eight hours of operation. In severe cutting conditions, recheck the blade carrier and blade bolt torque every 50 hours. To help prevent structural damage caused by loose hardware, tighten gearbox mounting hardware as specified. Check the fastener torque after first 8 hours of use and every 50 hours thereafter. Inspect the Blades daily for abnormal wear. REPLACE BOTH BLADES on that carrier IMMEDIATELY if either blade has: • Become bent or deformed from it’s original shape or • Any cracks are visible, or • Deep gouges in the blade’s surface are persent, or • Gouges or chipped areas in the cutting edge are larger than 1/2”(12.7mm), or • The material on the leading edge has been worn away by more than 1/2(12.7mm)” Failure to replace abnormally worn blades may lead to catastrophic failure of the blades and ejection of the broken part with tremendous force which may cause serious bodily injury or death. OPS-U-0032 OPERATION © 2010 Alamo Group Inc. OPERATION 2160 02/10 Operation Section 4-20 7.4 Blade Bolt Inspection Inspect Blade Bolt Head daily for wear as followed: Inspect the Blade Bolt Heads daily for abnormal wear. REPLACE BOTH BLADE BOLTS on the Blades IMMEDIATELY if either blade bolts has: • Visible cracks or • If the recessed area on blade bolt is worn off or • If Blade Bolt has gouges or chipped areas. Failure to replace abnormally worn blade bolts may lead to catastrophic failure of the blades and ejection of the broken part which may cause serious bodily injury or death. Always replace Blade Bolts with new bolts whenever replacing the Blades. OPS-U-0037 OPERATION © 2010 Alamo Group Inc.
