The hydraulics are the muscle of the forklift. The manual contains a schematic map of the hydraulic circuit. This helps technicians understand how the pump, control valve, lift cylinder, and tilt cylinder interact.
If you currently lack this manual, stop using the forklift. Contact a local Daewoo/Doosan material handling dealer (such as Bobcat or Clark dealer networks) with your model and S/N. Pay for the original. It will save you thousands in blown transmissions and hydraulic pump failures. daewoo g25s forklift manual
