INTERSTATE HEAVY EQUIPMENT - LAKEWOOD
Things can go awry even if you follow a strict maintenance schedule. Listed here are some of the most common excavator problems and their causes.
These are just general problems and solutions. First, contact your dealer or a local service professional to ensure that your excavator works correctly. If you aren't a certified technician, don't fix the problem yourself.
MY EXCAVATOR WON'T MOVE!
There are several possible causes for this. Outside of the final drive or travel motor, a problem could be a charge pump issue, being stuck in high-speed mode, a lack of pressure or flow in hydraulics, or a blockage in a motor case drain line.

HOW DOES IT GET SO HOT?
Overheating can be a problem for smaller excavators. Among the things to look for when your excavator is experiencing overheating issues:
- First, check the weight
- Next, make sure the exhaust is working properly.
- Then, check the radiator cap.
- Finally, make sure the radiator is clean.
WHY IS IT NOT STARTING?
There are some possible causes for this problem. Check out the following:
- It would be best to check the starter for voltage with a voltmeter if you have one.
- Look for any signs of damage to the directional joystick wire; it could be the problem.
- Check the starter's wires.
- As a precaution, check to see if the "dead man's switch" has been turned on.
WHAT'S WRONG WITH MY EXCAVATOR?
In most cases, this problem stems from a hydraulic system malfunction. A service technician should inspect the hydraulics. Some of the reasons include:
- Hydraulic seals that have corroded.
- Damaged or out-of-date hydraulic drives.
- An issue with the hydraulic pump.
