Repair cost: ₹1,500 to ₹5,000 (seal replacement)
₹500 to ₹2,000 (hose replacement)
Turnaround time: 1–2 days
Low Pressure or Weak Performance
What it looks like:
- Machine struggles to lift loads
- Slow operation
- Pump noise
- Low pressure readings
Why it happens:
- Worn pump internals
- Internal leakage in cylinders
- Wrong hydraulic oil
- Contaminated fluid
Repair cost: ₹3,000 to ₹15,000 (pump or seal repair)
