1. Check the hydraulic oil level and condition. The oil level should be between the "full" and "add" marks on the dipstick. If the oil level is low, add more oil until it reaches the "full" mark. The oil should also be clean and free of contaminants. If the oil is dirty, replace it.
2. Check the hydraulic filter. The hydraulic filter should be changed every 500 hours of operation. If the filter is clogged, it can restrict the flow of oil to the hydraulic system, causing problems.
3. Check the hydraulic pump. The hydraulic pump is the heart of the hydraulic system. If the pump is damaged, it can cause problems with the entire system. To check the pump, you can listen for any abnormal noises or leaks. You can also check the pressure at the hydraulic outlets. If the pressure is low, the pump may be damaged.
4. Check the hydraulic valves. The hydraulic valves control the flow of oil to the different components of the hydraulic system. If a valve is stuck or damaged, it can cause problems with the system. To check the valves, you can use a pressure tester.
5. Check the hydraulic hoses. The hydraulic hoses can wear out over time and develop leaks. If a hose leaks, it can cause problems with the hydraulic system. To check the hoses, you can look for any visible leaks. You can also press on the hoses to see if they feel soft or spongy.

If you have checked all of these things and you are still having problems with the hydraulic system, you may need to take the Valmet 702 to a qualified technician for further diagnosis and repair.

Here are some additional tips for fixing hydraulic issues in Valmet 702:

• Always use the correct type and viscosity of hydraulic oil.
