Then, do a walk-around inspection of the machine, paying special attention to guards and the drive system. Users should also make sure there is plenty of airflow for the cooling system. That is particularly important in hot weather, but also in winter when snow or ice might obstruct intakes.
But, don’t be tempted to open access panels or other parts of engine enclosures to ‘let in more air’. That can actually make things worse by disrupting the engineered airflow pattern around the engine and cooling system while allowing dirt, dust and other contaminants to more easily reach the engine. There are a few other things that users should not do:
• Don’t top off the coolant with plain water
• Don’t use expired DEF, or DEF stored more than a year in hot or cold conditions
• Don’t put anything but DEF in the DEF tank
• Don’t pour cold fuel into a hot fuel tank, it can cause water condensation.
