Avoid heat
The engine piston temperature is too high, easy to lead to overheating and burning cylinder; rubber seals, triangular tape, tires and other overheating, easy premature aging, performance degradation, shorten the service life; starter, generators, regulators and other electrical equipment The coil overheating, easy to burn and scrapped.
Avoid dirt
Fuel filter, oil filter, air filter, hydraulic oil filter and various types of filters and other parts if dirty, will lead to poor filtering effect. Water tank heat sink, air-cooled engine block and cylinder head heat sink, cooler heat sink and other parts too dirty, will lead to poor heat, the temperature is too high.
To avoid
Engine cylinder blades can not be installed in the installation can not be reversed, otherwise it will lead to premature ablation of the cylinder pad damage; engine fan blade can not be reversed; on the direction of tires, tonal tires, The word pointed to the rear.
Avoidance
If the valve is installed, such as missing or missing: will cause the valve out of control and hit the piston and other pieces; engine connecting rod bolts, flywheel bolts, drive shaft bolts installed on the cotter, locking screws, Or spring mats, etc., once leaked, in use will likely lead to serious failure occurred; engine timing gear chamber used to lubricate the gear oil nozzle once missed, will lead to serious drainage.
