In short: Grease and fluid checks daily. Filters and small services at 50 hours. Oil and hydraulic filter at 100. Full hydraulic fluid change at 250. Keep a log.
A mini excavator that is well maintained lasts twice as long as one that is not. Fluids, filters, pins, tracks – none of it is glamorous, but every hour you spend on maintenance saves ten in downtime. Here is the checklist we hand to every RIPPA owner in Ontario.
Maintenance interval overview
Every day (before you start)
- Walk around the machine, look for hydraulic weeps, loose bolts, damaged hoses
- Check track tension by eye – sagging tracks throw quickly
- Grease every pin and bushing on the boom, arm, and bucket
- Check engine oil, coolant, and hydraulic fluid levels (machine level, boom down)
- Clear debris from around the radiator and air intake
- Test all controls before you load material – a slow cylinder now is a broken cylinder later
Every 50 hours
- Full grease service – every zerk on the machine, not just the obvious ones
- Check air filter – clean or replace if there is visible buildup
- Check battery terminals, tighten if needed
- Inspect tracks for cuts, missing chunks, or exposed cords
- Look at the cutting edge on the bucket – a worn edge doubles your dig time
Every 100 hours
- Change engine oil and oil filter
- Replace fuel filter and water separator
- Check hydraulic return filter
- Inspect all hydraulic hoses for chafing, especially where they cross the swing frame
- Torque check on track bolts and mounting hardware
- Grease the swing bearing (often the missed one that causes big repair bills later)
Every 250 hours
- Replace hydraulic fluid and hydraulic filter
- Replace air filter (do not just clean it)
- Coolant check – top up or replace based on strength test
- Inspect and adjust final drive fluid on both tracks
- Pin and bushing inspection – replace bushings that have gone oval
- Full electrical inspection – connectors, harnesses, fuses
Ontario winter storage matters.
Fill fuel tank, add stabilizer, grease everything, disconnect battery or use a maintainer, cover exposed cylinder rods. In spring: full walkaround, check for rodent damage, idle 5 minutes before loading to warm the hydraulic oil.
Three things that cause the biggest bills
- Skipped hydraulic fluid changes. Contaminated fluid grinds pumps and valves. A $200 fluid change beats a $4,000 pump.
- Loose tracks. Tracks thrown mid-job usually damage sprockets and rollers on the way off.
- Neglected greasing. Dry pins wear the bushings, then the pins, then the boom pinbore. Fixing a worn pinbore requires machining.
Keep a log
Track hours and what you did at each service. A simple notebook in the cab beats trying to remember when you last changed the hydraulic fluid. Service records add real resale value.
