Key Maintenance Tips to Prolong the Life of Your Mini-Excavator

Despite their modest size, mini-excavators need just as much maintenance as their larger counterparts. With the arrival of spring and the busy season gearing up, properly maintaining your machine is more important the ever.


We all know that time is money. If your machine fails unexpectedly on the job site, that downtime is going to dig into your profits. Avoid unnecessary delays with your rental equipment in Airdrie by having your operators sign-off on a routine checklist.


Top 5 tips to keep your machine in top working condition


1) Lubricate all moving parts daily

Harsh, muddy working conditions cause significant wear and tear on the moving parts of the machine. So it’s critical to lubricate all the pins and bushings every day to keep them from seizing up. One or two shots of grease on each joint is all you need to keep it well-lubed.


2) Change the hydraulic oil

Hydraulic systems have very specific tolerances, and failures are usually due to contaminated oil or even the wrong oil being used in the machine. Just because it isn’t cloudy doesn’t mean it shouldn’t be changed. For most mini-excavators, have the oil changed every 1000 hours, even if it looks clean.


3) Check the gearbox

It’s common for the propel drive gearbox to get caked with mud, covering up the fill and drain plugs. This makes it easy for operators to miss their daily checks, so make sure it’s frequently washed down. Most manufacturers suggest changing the gearbox oil approximately every 1000 hours. It only holds about half to one quart of oil, so it’s a quick process for your service tech.


4) Adjust track tension

Test the track tension. If the tension is too loose, it won’t maneuver well and could cause the track to come off its idler and drive sprocket. If it’s too tight, it could cause the track to tear and halt production completely until a new one is installed. Refer to the track sag measurements in the operator’s manual and adjust the tension daily.


5) Keep maintenance records

Keep all your service records and invoices on file to refer back to if you suspect that the machine may need servicing. Eventually, they all reach the end of their service life and having accurate records will help immensely if you run into any warranty issues.


Always refer to your operator’s manual for timelines and maintenance checklists for your specific construction equipment rentals. In Airdrie and Edmonton, W.R. Scott Equipment Ltd. maintains, sells and rents a range of excavators, track loaders, skid steers and attachments.
