PART 01: Use the Correct Grade of Diesel
In low-temperature environments, it’s crucial to use diesel with an appropriate low pour point. Using high pour point diesel in winter can lead to "waxing," which makes engine startup difficult. If waxing occurs, avoid force-starting the engine. Instead, clean the fuel lines, replace the filters, or wait for temperatures to rise before operation. If low-pour diesel is unavailable, consider adding a pour-point depressant as a temporary solution.
Additionally, always fill the fuel tank completely before parking the excavator to prevent moisture condensation and freezing inside the tank. For extended downtime, an empty or partially filled fuel tank is more prone to rusting.
PART 02: Use Genuine Antifreeze
Timely replacement or replenishment of genuine antifreeze is essential to protect the engine block from damage caused by freezing temperatures. Antifreeze isn’t just for winter; it should be used year-round. While it prevents freezing in winter, it also helps regulate engine temperature in summer. Avoid using plain water, as it lacks the cooling and protective properties of antifreeze.
PART 03: Warm Up the Excavator Before Operation
Starting the excavator and immediately putting it to work in cold weather can cause severe wear and tear. Always perform a proper warm-up:
1. Activate the preheat switch and let it run for about 10 seconds before starting the engine.
2. Let the engine idle for 5 minutes to stabilize.
3. Gradually operate the working components for about 15 minutes to ensure the hydraulic fluids flow properly and reach optimal temperature.
Before starting work, check all gauges and indicator lights to ensure everything is functioning correctly. Only begin operations once the engine is running smoothly.
PART 04: Maintain Proper Insulation After Operation
In cold climates, excavators can overcool, leading to engine damage and reduced service life. After work, park the excavator in a garage whenever possible. If outdoor parking is unavoidable, protect the machine by placing a cardboard shield in front of the radiator to block cold winds.
Additionally, the thermostat plays a vital role in regulating the engine's temperature during operation. Before winter begins, inspect the thermostat to ensure it is functioning correctly and replace it if necessary.
PART 05: Prioritize Safety During Winter Operations
Winter conditions, such as frequent snow and hidden ice beneath it, can increase the risk of accidents. On slippery surfaces, sudden turns can cause skidding and potential hazards.
Operate the excavator at a steady, controlled speed, and avoid steep slopes or abrupt stops. Use the engine and attachments to provide additional resistance when driving downhill. Keep a safe distance from nearby objects to prevent collisions caused by unexpected sliding.
By following these professional tips, you can protect your excavator from the challenges of winter and ensure safe, efficient operations throughout the season. At Origin Machinery, we’re here to support you with high-quality equipment spare parts and expert advice, no matter the conditions.
