Mechanical Failure Signs
Leaking fuelLeaking hydraulic fluidCooling system leakMotor oil leakOverheating of componentsVibrations and noisesStress cracks
Cold TemperaturesSlower operation due to thick hydraulic fluidSteel affected ( minimized shock load)Ice forming on ladder ( increased weight)Frozen hydraulic linesWon’t retractFreezing runoff ( truck may slide downhillDrain water pipe as soon as completed with it
