What to do if Soosan SQ breaker fails to hammer?
- S
  Stephen RiceAug 10, 2025
  If your Soosan Construction Equipment breaker fails to hammer, it could be due to several reasons. First, check if sufficient high-pressure oil is flowing to the breaker inlet. If not, inspect, clean, and repair the piping, or replace it if necessary. If the oil flow is sufficient, examine and repair the valve and its related parts, or replace them. Also, ensure that the hydraulic oil level is adequate by refilling the oil tank. If these steps don't resolve the issue, there may be internal breaker defects, and you should consult with a service station.

Why is the hammering force reduced on my Soosan SQ Construction Equipment?

  If your Soosan Construction Equipment's hammering force is reduced, start by checking if sufficient high-pressure oil is flowing to the breaker inlet. If not, check, clean, and repair the piping, or replace it. If the oil flow is sufficient, inspect the control valve and related parts, replacing them if needed. Ensure you have enough hydraulic oil by refilling the tank. If the hydraulic oil is contaminated or deteriorated, flush the tank and change the oil entirely. A defective pump could also be the cause, so you may need to ask a service station for base machine service. Also, check the N?-gas pressure of the back head and adjust the gas pressure referring to Chapter 10. If none of these steps work, there may be internal breaker defects, requiring consultation with a service station.
