As we arrive at the Major Cold solar term—the coldest period of winter—many excavators are working in snow-covered and freezing environments. While we bundle up in thick winter clothing and warm ourselves with hot tea or coffee, our hardworking machines outside also need extra care.
Winter maintenance isn’t just about protection—it’s about performance, reliability, and safety. Let’s talk about how to keep your excavator warm and ready during the coldest days of the year.
Engine: A Proper Warm-Up Matters
Some say the engine needs a warm-up routine—and they’re right.
Start by running the engine at low speed and observe whether the sound and exhaust are normal. Then gradually increase engine speed, allowing the bucket and linkage to move fully. Lift each track in turn so the travel motors can also warm up and circulate oil properly.
A thorough warm-up helps reduce wear, improves lubrication, and prepares the entire hydraulic system for winter operation.
Greasing: Dressing the Machine for Winter
Others say the machine needs a winter coat.
Ideally, equipment should be parked indoors. If that’s not possible, at least choose a sheltered, wind-protected location. Joints and pivot points are especially vulnerable in cold weather—make sure all exposed pins and rods are well-greased.
That “grease jacket” not only keeps moisture out, but also protects components from freezing temperatures and accelerated wear.
Winter Fluids: A Seasonal Menu for Your Machine
Some believe the machine needs a proper winter diet—and that’s absolutely true.
Use high-quality antifreeze coolant, ensuring sufficient volume and correct concentration
Switch to higher-grade engine oil suitable for low temperatures
Select winter-grade diesel fuel based on local climate conditions
Adjusting fluids according to ambient temperature ensures smooth starts, stable operation, and reliable protection throughout winter.
Cold weather may be unavoidable—but with the right care, your excavator can face winter with confidence. After all, a well-maintained machine is the warmest companion on a cold jobsite.
