Hydraulic Oil Temperature
It is extremely important that the hydraulic oil temperature be checked periodically during operation. Continuous operation of the machine with high hydraulic oil temperatures will cause rapid wear and failure of pumps and motors. If the hydraulic oil temperature rises to 210°F (99°C) and remains there or continues to rise, shut the engine down and thoroughly clean the exterior surfaces of the hydraulic oil cooler and radiator. Use an air hose to remove any loose material and then, if necessary, use a steam cleaner to remove any remaining material. Also check the condition of the engine coolant and, if the coolant shows signs of system corrosion, flush and clean the cooling system.
COOLING SYSTEM RETURN FILTERIf the hydraulic oil temperature continues to register too high, the return filter elements are clogged and the hydraulic oil is bypassing the filter AND THE OIL COOLER (see page 2-24). Shut the engine down immediately and change the cooling system return filter elements (see page 5-38).Wheel Drive System
If during operation the wheel drive system seems to be responding sluggishly and/or there is a rattling or pinging noise in the wheel drive pump, shut the engine down immediately and change the wheel drive pump suction filter element (see page 5-38).If the system continues to respond sluggishly and/or the rattling or pinging noise continues, refer to the Sundstrand Service Manual.Water Spray System
Although it may not appear to be important, the water spray system is one of the key factors to effective machine operation. If the system does not work properly, excessive dust can settle in the radiator and oil cooler and cause damage because of overheating. It is therefore important that the operator watch for any indication of plugging of the nozzles. If the nozzles appear to be plugging up, the operation should be stopped, the nozzles cleaned (see page 5-6) and the strainer screen removed and cleaned (see page 5-23). If the water in the tank is excessively dirty, drain the tank and refill it with clean water.To avoid needless down time: 1. Always use the cleanest water possible.2. Visually check the operation of the spray nozzles periodically during the day by performing the following: a. Raise the main cutter and auxiliary cutter to their upper limits. Block the cutters up.b. Set the cutter controls at "Off".c. Turn each cutter spraybar on.d. Check the pattern and amount of spray for each nozzle.e. Remove and clean the nozzles as required (see page 5-6 for procedures).
INADVERTENT ENGAGEMENT OF THE CUTTER CAN CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH.
3. Flush the strainer screen daily by opening the valve on it and allowing the water to flow out for a minute or two.Cutter Belts
New cutter belt sets will stretch when they are first put into operation. If the belt tension is not readjusted as the belts stretch, the belts will start to slip or slip-and-grab, causing the belts to break. IF the belts do not break, the slipping
