HIGH ALTITUDES
Variations in altitude alter the fuel/air mixture burned in the engine and affect the engine’s
performance. At high altitudes, atmospheric pressures are lower and less oxygen is
available for combustion of the fuel. Above 10,000’ the engine fuel injectors may have to be
changed to ensure proper performance. Consult engine manufacturer should this problem
arise.
Keeping the air cleaner clean and free of obstructions will help alleviate high altitude problems.
At high altitudes, closely monitor the engine temperature for overheating.
AIR BRAKES
At least once a day, drain the water accumulation from the air tanks.
