Four - Step Winter Maintenance: Bid Farewell to the "Cold Start" Problem of Loaders
As the temperature drops sharply, the engines and hydraulic systems of your wheeled loaders will face greater challenges. Follow this winter-specific checklist to ensure that your equipment operates efficiently and stably in cold environments.
Four Essential Winter Maintenance Steps
Switch to Low-Viscosity Oil
Under low temperatures, conventional hydraulic oil will thicken and its fluidity will deteriorate. Please replace it with 10W-30 or winter-specific hydraulic oil in a timely manner.
Why This Matters:
Ensures oil can be smoothly delivered to the oil pump and valve bodies during cold start
Guarantees system response speed in freezing conditions
Prevents excessive wear on hydraulic components
Reduces strain on hydraulic pumps during startup
Battery Health Check
In a low-temperature environment, the battery power may decline by up to 50%. Be sure to keep the electrode connections clean and confirm that the charging system is in the best condition.
Winter Battery Care:
Clean battery terminals to prevent corrosion buildup
Test battery capacity before winter begins
If equipment is left idle, remove battery and store in warm environment
Consider battery blanket or heater in extreme cold
Anti-Freezing and Fuel Treatment
Check the freezing point of the coolant to ensure it meets the local minimum temperature requirements. At the same time, use winter-grade diesel or add anti-gelling additives.
Fuel & Coolant Protection:
Prevent diesel from "waxing" and blocking filter elements
Use winter-grade diesel appropriate for your temperature range
Ensure coolant freezing point is below expected minimum temperatures
Add anti-gel additives if using summer-grade diesel
Standardize the Warm-up Process
Never carry out heavy-load operations directly in a cold-engine state. After starting, let the engine idle for 5-10 minutes to allow the hydraulic oil to fully circulate and heat up to the operating temperature.
Proper Warm-up Protocol:
5-10 minutes of idling before operation in cold temperatures
Gradually increase load over first 15 minutes of operation
Protects oil seals from cracking due to cold brittleness
Prevents hydraulic system leakage in extreme cold
How Cold Temperatures Affect Your Loader
Dangers of Improper Cold Starts
Starting a loader without proper winter preparation can cause:
Hydraulic pump cavitation and failure
Oil seal cracking and hydraulic leaks
Battery failure and starter motor damage
Fuel filter clogging and engine stalling
Increased engine wear and reduced component life
