Cold Weather Operation
If you plan to use your excavator through winter, prepare it for the cold:
Engine Prep
- Switch to 5W-40 or 0W-40 diesel oil for cold starts
- Install a block heater if temperatures drop below 20°F
- Check glow plugs and timer function
- Consider a fuel additive to prevent gelling
Hydraulic System
- Switch to ISO 32 hydraulic fluid for better cold flow
- Warm up hydraulics slowly before heavy work
- Check hoses for cracks (cold makes rubber brittle)
Tracks
- Clean tracks thoroughly before freezing weather
- Check tension more frequently (cold changes track dimensions)
- Consider track pads for ice and snow traction
Long-Term Winter Storage
If storing your excavator for winter (common in northern states):
Fuel System
- Fill tank completely (prevents condensation)
- Add fuel stabilizer per manufacturer instructions
- Run engine for 10 minutes to circulate treated fuel
Engine
- Change oil and filter before storage
- Remove and charge battery, store indoors
- Plug exhaust and intake with steel wool (prevents pests)
Hydraulics
- Extend all cylinders fully (protects rod from weather)
- Apply grease to exposed cylinder rods
Tracks and Undercarriage
- Clean thoroughly to remove mud and debris
- Store on blocks or wood (relieves track tension)
General
- Cover the machine or store indoors
- Start and run monthly if possible
- Document storage date and maintenance performed
