Mini excavators, or what most people refer to as compact excavators, are popular because of their power and versatility. These things aren’t mini when it comes to their uses. However, we all know that time is money and time lost due to machine failure means being unproductive.
More than the routinary preventive maintenance on your mini excavator, you should also ensure that you’re looking out for things that may pose future damages. When you see the signs early, you can prevent unnecessary repairs and prolong the life of your machine. Also, transporting your mini excavator to a repair shop can be quite costly. So, save yourself from a headache and the hassle and look for these signs.
What Signs Should I Look For?
Consistent Overheating
If you’re noticing that your mini excavator is heating up faster than it usually does, then this may be a manifestation of something serious. Check for the following:
- Coolant temperature – Check to see if the coolant needs flushing or replacement. Your mini excavator should not be overheating whether the AC is turned on or off. Dislodge any trapped debris in the hydraulic cooler and radiator.
- Radiator – Another component to check is the radiator core. Particles can get stuck in the core which causes airlock and overheats your machine. Clean them with a leaf blower or compressed air.
- Thermostat – If the temperature is acting up, then the thermostat may be the culprit. Check your manual on how you can replace it or ask assistance from a technician.
Low Powered
If you’re having a hard time digging or doing quick maneuvers, then your mini excavator may be experiencing some power problems. Do the following steps to find what’s causing the problem:
- Examine your filters – Inspect your fuel filters and air filters for any damages or if they need replacement. Air filters do not require cleaning, and it’s unwise to take them out of their units if not needed. Be sure to refer to your manual for safe steps in handling these filters. Address any problems you see and consult an expert if you’re unsure.
- Perform a cycle time check – If the above-mentioned does not work, you can check the cycle time of your mini excavator. Cycle time is the amount of time it takes your mini excavator to fill its bucket, dump, and swing back to get the next load. If you’re noticing that it takes longer than it usually does, have a certified technician look for the cause.
Track Problems
Some mini excavators come with rubber tracks. This kind of track is versatile, provides stability, and offers a better ride overall. Rubber tracks come in different widths to accommodate varying needs.
However, rubber tracks are prone to problems especially if used on uneven surfaces. If you see unusual wear and tear on your tracks, such as cuts or distress, consider replacing them to avoid future problems. The steel embeds on your rubber tracks should also not be showing. Doing a daily visual check on your tracks could eliminate costly repairs.
When replacing the rubber tracks on your mini excavator, you should also check to see if the track tensioning is correct. Tracks like Fortis Rubber Tracks are appropriately tensioned and can help prevent accelerated wear and tear on your undercarriage.
Features That Makes Maintenance Easier
Sometimes seeing the signs of repair means that you’re not doing proper maintenance. If you’re in the market for a new mini excavator or if you’re planning to rent one, you should look for these three features for efficient machine maintenance.
- Easily accessible engine – Nothing is more difficult than an engine placed in the most inaccessible areas. A mini excavator’s engine needs regular maintenance, and to make your life easier, look for something that has large door access and organized filters. Also, the manual engine stop should be easily accessible as it is a safety feature that can prevent accidents.
- Grease points located on one side of the boom – Greasing is vital in any heavy machinery and this is very accurate for a mini excavator. With all of its moving parts, greasing on a daily basis is the best way to keep your machine running properly. Having all of the grease points on the same side makes greasing easier and far less uninteresting.
- Electronic panels – Newer models are now equipped with electronic screens, which make everything easier. It can show reminders on when to do routine checks and provides information on how you can address any mechanical problems. Additionally, it can alert the operator of any problems before it even occurs.
Proper maintenance and proper visual checkups are crucial to prevent your mini excavator from having problems. With repair costs increasing, you have to be vigilant and spot the signs of possible repairs before they even happen.
