   Why change the oil in my forklift every month or at the 200-hour mark?

   There is a huge difference between forklift and a regular truck regarding applications and load conditions. If you compare the vehicles equipped with almost the same capacity engine you will find that the service weight of a forklift is much heavier than a truck and the rate capacity is bigger than the loading capacity of a truck by at least 50%. The frequency of load changes is incomparably high in the operation of a forklift.

   Therefore it is quite natural that, not only engine oil and hydraulic oil, but also filters, element or air filters deteriorate much faster.

   What will happen if I don't change the oil in my forklift?

   Forklift engine oil has a limited life. After a certain point it starts losing lubrication quality and carbonizes. Once this happens, the engine gets contaminated with carbon deposit or sludge.

   When you miss your oil change the engine starts wearing much faster with scuffing engine parts. Regular oil changes are vital to keeping the engine in good shape for a long period of time.

   Why do I have to replace the oil filter?

   Forklift engine oil filters work to purify sediments of impurities including metal particles and carbon or sludge contained in the oil. Once carbon deposits start clogging the oil pick-up screen decreasing oil supply and increasing friction. At the same time, the oil fails to purify and can bypass filter flowing direct to cause wearing and scuffing bearings and crankshaft.

   Why do I have to replace the air filter?

   Abrasive wear of pistons, piston rings, and cylinder liner can be seen after inhaling dirt inside the engine due to damaged element which eventually may cause decreased compression and loss of engine power. Moreover, the engine burns out faster by leaking oil from the scuffling space which may cause increased fuel consumption.

   How important is the fuel filter?

   The plunger of fuel injection pump is precisely fitted to the barrel with very small clearance to form it perfect sealing and moves hard following to engine rotation.

   If the dirt contaminate fuel enters the precision clearance, the plunger can be damaged and break down. The fuel filter is a very important part in straining impurities to avoid such trouble.
