Excavators help workers complete various tasks on a worksite. They can push, pull, and dig using a specially adapted arm.

For some situations, a mini excavator might be preferable, but you’ll want to be sure it’s performing at its best. Here are the top five maintenance issues for mini excavators that you should be aware of during operations.

Track Adjustment

Mini excavators rely on their tracks for getting around in uneven terrain. Covering wheels in rubber tracks reduces vibrations during movement, preventing parts from being damaged while driving the vehicle from one location to the next. Unfortunately, if the track is misaligned, it can cause added wear to the machine.

Proper track tension is essential when operating a mini excavator. If the tension is too tight, it can cause damage to the parts. If it’s too loose, the tracks can slip off, creating a real problem.

Bad Parts

Another critical issue to watch out for when maintaining your mini excavator is the presence of damaged or failing parts. When parts go bad, the excavator might not function properly. Improper maintenance can also cause unnecessary wear on the machine.

While Original Equipment Manufacturers (OEMs) offer replacements, many opt to get them instead from a trusted third-party seller. The best Caterpillar aftermarket parts can save money and make it easier to maintain your mini excavator.

Hydraulics

Mini excavators rely on hydraulics to give them added power when doing big jobs. Hydraulics use the liquid to add pressure to contained areas, creating a mechanical movement that they can leverage to move large objects.

Hydraulics create more precise movements that allow excavators a full range of motion to do their work. If hydraulics fail, the excavator will be unable to work correctly.

Low Fluid

Like most vehicles, mini excavators rely on various fluids to ensure the engine operates correctly. Oil and coolant are vital to proper performance. If either fluid runs out or sits too long without anyone changing it, it could cause significant problems. The engine could burn out, making the entire machine useless.

While oil lubricates internal components, coolant keeps the engine from overheating. It’s essential to regularly inspect levels, check for leaks, and make changes to ensure your mini excavator lasts.

Attachments

In most cases, excavators will use specialized attachments to perform specific tasks. You must properly fasten and secure these attachments to limit potential hazards. If the bucket comes off in the middle of operating, it can cause damage to the equipment or harm to workers.

Learning about the equipment you’re using on the job is essential. Each attachment will have its own maintenance requirements, which you’ll find in the owner’s manual.

Make Sure Your Mini Excavator Lasts

You should always be aware of your equipment and its needs while on the worksite. The top maintenance issues for mini excavators can derail operations with little notice.

Take the time to do regular maintenance and stick to best practices when operating so that you don’t run into any problems.
