Check the level frequently and add distilled water as required to maintain the proper level. Keep air circulation free. Air circulation 1. around the engine and battery must not be restricted. Keep air intake and exhaust openings clear of leaves, paper and other foreign matter which may restrict air flow. Keep the engine clean of dirt, grease and other substances which inhibit heat dissipa- tion. Use sound judgment in operating the engine. Avoid the two extremes of racing and lug- ging. Advance the throttle only enough to handle the load, yet be certain that the engine speed is high enough to maintain adequate fan speed for cooling. Run the engine only when engaged in work operations or when traveling the vehicle. Avoid prolonged periods at idling and shut the engine down if operations are interrupted. Sandy or Dusty Work Sites The presence of large amounts of sand or dust at the work site can contribute to accelerated component wear. Either substance will act as an abrasive when deposited on moving parts. The problem is combated by more frequent lubrica- tion and by the servicing of breathers and filters at shorter intervals. Follow the recommendations below when operating in sand or dust on a regular basis: 2. Check the filler caps, filters, breathers, air cleaner and grease fittings. Keep sand and dust out of the hydraulic system by keeping the reservoir filler cap tight and servicing the hydraulic system filters frequently. The fuel system should be kept free of sand and dust by keeping the tank filler cap tight and servicing the fuel filters frequently. When lubricating, thoroughly clean each grease fitting before attaching the grease gun. Pump generous amounts of grease into all lubrication points, using the fresh grease to pump out the old grease. The increased frequency of lubrication and service noted above should be determined by observations made at work site. Inspection will indicate how long it takes for lubricants, breathers and filters to accumulate unacceptable amounts of sand or dust. The frequency of lubrication and service should be adjusted accordingly. The engine and air cleaner should also be serviced frequently to prevent sand and dust from entering the engine. The engine oil and oil filter should be changed at shorter than normal intervals to insure a clean oil supply to the engine’s moving parts. Adequate ground bearing support must be provided for the outrig- ger when operating on soft surface. Be alert for signs of LRT 110 Crane movement during operations. Failure to follow this procedure could cause DEATH or serious injury. Insure that the terrain is adequate to support the crane’s weight. 4-7 0
