01 Unstable pressure and unstable spraying width. It is strictly forbidden to disassemble and replace the voltage regulator tube by yourself. The 15M voltage regulator tube plays an important role in voltage stabilization and energy storage. Do not disassemble or replace the voltage regulator tube with a length different from the original one by yourself.

02. The return pipe is still returning after the return valve is closed. When the return valve is closed, the return pipe is still returning. Consider that the return switch is damaged. Contact after-sales for repair and replacement.

03. The sealing ring is aging and damaged. Replace the plunger rod sealing ring.

04. The suction pipe is damaged and leaking. Check whether the suction pipe is damaged or leaking. If the above situation occurs, replace the suction pipe.

05. The hydraulic oil filter is seriously dirty. Check and replace the new hydraulic oil filter in time.

06. The hydraulic oil is aging or insufficient. Check the hydraulic oil surplus and quality, and add or replace the hydraulic oil in time.

07. The hydraulic oil pump is damaged. Check whether the hydraulic oil pump is operating normally. If it is damaged, please contact after-sales for repair and replacement in time.
