<div class=”ace-line ace-line old-record-id-SU1cfrLdudPvULcpofgcmmhnnqh”>Slow hydraulic action is a common issue on compact excavators, which directly affects working efficiency.</div>
<div class=”ace-line ace-line old-record-id-SU1cfrLdudPvULcpofgcmmhnnqh”>Here are the main causes for daily reference.</div>
<div class=”ace-line ace-line old-record-id-QTzCfu7Z9dkN8Tc1yOqc33lpnMd”>1. Hydraulic oil aging or contamination</div>
<div class=”ace-line ace-line old-record-id-C9TOf3yBNdJq0rci8blcGSqTnLe”>Overused, deteriorated or dirty hydraulic oil will increase system resistance, resulting in slow and unsmooth movements. Regular oil replacement is essential.</div>
<div class=”ace-line ace-line old-record-id-Ew5LfpevBdCuF6c804JcVBfEnqg”>2. Clogged filters</div>
<div class=”ace-line ace-line old-record-id-Z08jfgC9FdATDCcMJ8Rc3NoqnFh”>Blocked oil suction filters and return filters reduce oil flow, limiting the hydraulic system’s working response.</div>
<div class=”ace-line ace-line old-record-id-WrSjfYKj6d0mk7cghb4csRbbnce”>3. Insufficient hydraulic pressure</div>
<div class=”ace-line ace-line old-record-id-Z0E6fiOfddFaUfcHEZOcGXYvnbf”>Worn hydraulic pumps, valve core wear or improper pressure setting will lead to insufficient system pressure and weaker digging & moving speed.</div>
<div class=”ace-line ace-line old-record-id-OttNfLPVTdHD7UcBenkcEwJRnJf”>4. Oil leakage inside the system</div>
<div class=”ace-line ace-line old-record-id-LiEmfkhRwdADD1c7HxHcmqOSnne”>Internal leakage of cylinders and valves causes pressure loss, making machine actions sluggish, especially under load.</div>
<div class=”ace-line ace-line old-record-id-NyCBfturgd4Rs9csjXGc3BN3nIb”>5. Improper operation and maintenance habits</div>
<div class=”ace-line ace-line old-record-id-IYpAfvBSddXDF4cvgAOcubmUngh”>Long-time heavy-duty work without rest or lack of daily maintenance will accelerate hydraulic system aging and slow down overall performance.</div>
<div class=”ace-line ace-line old-record-id-BClhfQQsOdf2IEcNzSLc45uqnFh”>Timely inspection and standardized maintenance can effectively avoid slow hydraulic issues and keep the machine in stable condition.</div>

<span dir=”auto” style=”vertical-align: inherit;”><span dir=”auto” style=”vertical-align: inherit;”>堵塞的吸油过滤器和回油过滤器会减少油流量，限制液压系统的工作响应。</span></span>

<span dir=”auto” style=”vertical-align: inherit;”><span dir=”auto” style=”vertical-align: inherit;”>3.液压压力不足</span></span>
<span dir=”auto” style=”vertical-align: inherit;”><span dir=”auto” style=”vertical-align: inherit;”>液压泵磨损、阀芯磨损或压力设置不当会导致系统压力不足，挖掘和移动速度变弱。</span></span>

<span dir=”auto” style=”vertical-align: inherit;”><span dir=”auto” style=”vertical-align: inherit;”>4. 系统内部漏油</span></span>
<span dir=”auto” style=”vertical-align: inherit;”><span dir=”auto” style=”vertical-align: inherit;”>气缸和阀门的内部泄漏会导致压力损失，使机器动作迟缓，尤其是在负载情况下。</span></span>

<span dir=”auto” style=”vertical-align: inherit;”><span dir=”auto” style=”vertical-align: inherit;”>5. 不正确的操作和维护习惯</span></span>
<span dir=”auto” style=”vertical-align: inherit;”><span dir=”auto” style=”vertical-align: inherit;”>长时间重载工作而不休息或缺乏日常维护会加速液压系统的老化，并降低整体性能。</span></span>

The main causes for slow‑running hydraulic systems of mini excavators include deteriorated or insufficient hydraulic oil, clogged filter elements, worn hydraulic pumps, low pressure setting of relief valves and pipeline leakage.

Your products are worth recommending. I’ve bought one.

“Actually, I bought an electric forklift from your company a while back. I’ve been running it for two years now, and it’s been a solid machine. Really happy with the experience!

[EpsieMilbry]

When purchasing a multi‑functional backhoe loader, which attachments do I have to buy together with the machine?

[DebbiePeixoto]

I bought an excavator from you, and it works great.
