  • Oil in the motor may be dirty.
  • There may be oil leakages.
  • The excavator tracks may be too loose.
  • The hydraulic pump may be faulty.

Troubleshooting Excavator Stopping And Getting Hard To Manoeuvre

When this problem occurs make some checks. Pay attention to and do the following:

  • Ensure the oil in the motor is not contaminated; replace where necessary.
  • If there are leakages, plug them.
  • If the excavator tracks are too loose make adjustments.
  • Fix or even replace the hydraulic pump.

5. Overheating

It is possible that at times your Sunward Excavator may experience overheating. The good thing is that overheating can be easily prevented or rectified. Here are some possible causes of the problem:

  • Faulty cooling system.
  • Hoses may be damaged or leaking.
  • There may be contamination in e.g. oils.
  • Connecting incompatible attachments.

Troubleshooting Overheating Problems

Once you have ascertained the cause behind the overheating, you can do the following:

  • Fix the cooling system e.g. ensuring the coolant is adequate.
  • Fix damages or make replacements of hoses.
  • Ensure oils are not contaminated.
  • Do not connect attachments that exert duress on your excavator.
