Before using any device, it is necessary to warm up the machine, which can enter the working state faster. Many people believe that warming up is cumbersome, time-consuming, and can still be used without the need for it. Little do they know that warming up is a crucial process.

The inherent characteristics of being busy at both ends determine one's advantages. In the case of multifunctional operation, warming up can slow down the speed of oil seal wear.

When hydraulic oil is in a static state, it forms a solid oil film and adheres between the piston and oil seal. Warming up the engine can allow the wet hydraulic oil to wash under the relatively solid oil film, establishing a new hydraulic oil film and spreading the oil seal to ensure that the piston and oil seal will not be pulled or damaged in the initial stage.

Warm up program: Step on the foot valve with a stroke of ≈ 13, and the main oil inlet pipe slightly shakes (near the oil pipe on the side of the cab). Maintain the foot stroke for 20 minutes to 40 minutes.

When both ends are busy starting to work and are in a cold engine, suddenly hot oil will cause damage to the oil seal due to thermal expansion and contraction. Fast frequency movement is more prone to oil leakage, and the oil seal is replaced frequently.
