Section IV. OPERATION UNDER UNUSUAL CONDITIONS
2-36. OPERATING FORWARD REPAIR SYSTEM (FRS) IN EXTREME HEAT.
When operating FRS in very hot temperatures of above 100 F (38 C), extra care must be
taken to prevent overheating generator (temperatures over 230 F [110 C]). Watch water
coolant temperature gage closely.
Check oil levels often. Generator cooling and lubrication systems support each other.
Failure of one system may rapidly cause failure of other system.
Air compressor will cause the welder to shut down when air compressor starts. Welder
duty cycle is approximately 60% of normal at 120F.
Let the engine run with no load for about two minutes before shutting down. This will cool the engine
faster than quick shutdown and may prevent damage from remaining engine heat.
Check the oil levels often. Oil seals are more likely to leak in extreme hot weather.
Check cooling system often. If any of the following conditions are found, notify Unit Maintenance:
Low coolant level in coolant reservoir or radiator.
Leaking hose connections which have been tightened but still leak.
Cracked or leaking hoses.
Radiator fins plugged with dust, leaves or insects.
Clear intake duct.
