- How Does Temperature Affect Lubricant Replacement?
Lubricant performance varies under different temperatures:
- High-temperature environments (e.g., Middle East, Southeast Asia):
Lubricants oxidize and degrade more easily, viscosity drops, and lubrication effectiveness declines. Replacement intervals should be shortened. - Low-temperature environments (e.g., Russia, Northern Europe):
Lubricants may thicken, reducing flowability and affecting equipment startup and lubrication. Low-temperature-grade lubricants are required. - Temperate climates (e.g., Central Europe):
Lubricant performance remains relatively stable, allowing standard replacement intervals.
- Recommended Lubricant Change Intervals for Mini Scissor Lifts
- Normal conditions (conventional temperatures: -10°C to 35°C): Every 1,000 hours or 24 months (whichever comes first).
- High-temperature/heavy-load conditions (e.g., Middle East, Southeast Asia): Every 800 hours or 18 months (heat accelerates oil degradation).
- Extreme cold conditions (e.g., Russian winters): Every 600 hours or 12 months (low temperatures may cause condensation; early inspection is advised).
- Lubricant Replacement Recommendations for Different Regions
(1) Middle East (e.g., Saudi Arabia, UAE)
- Average annual temperature: 25°C–45°C (can exceed 50°C in summer).
- Recommendations:
- Use high-temperature synthetic lubricants (e.g., SAE 10W-40 or 20W-50).
- Shorten replacement intervals to 600 hours or 12 months.
- Regularly check for thinning or darkening of oil.
(2) Southeast Asia (e.g., Thailand, Malaysia)
- Average annual temperature: 28°C–35°C (high humidity).
- Recommendations:
- Use moisture-resistant, oxidation-resistant lubricants (e.g., ISO VG 68).
- Replacement interval: 600–800 hours or 12–18 months.
- Monitor for emulsification (water contamination).
(3) Central Asia (e.g., Kazakhstan, Uzbekistan)
- Average annual temperature: -5°C–35°C (cold winters, hot summers).
- Recommendations:
- Use all-season lubricants (e.g., SAE 15W-40).
- Replacement interval: 1,000 hours or 24 months (inspect during seasonal transitions).
(4) Russia
- Average annual temperature: -10°C–25°C (Siberian winters can reach -40°C).
- Recommendations:
- Winter: Must use arctic-grade lubricants (e.g., SAE 0W-20 or 0W-30).
- Replacement interval: 600 hours or 12 months (inspect before winter).
(5) Europe (e.g., Germany, France)
- Average annual temperature: 0°C–30°C (mostly temperate climate).
- Recommendations:
- Use multi-grade lubricants (e.g., SAE 10W-30 or 5W-40).
- Replacement interval: 1,000 hours or 24 months (routine checks suffice).
- How to Properly Replace Lubricant?
- Cool down: Let the equipment sit idle for 30 minutes to lower oil temperature.
- Drain old oil: Locate the drain plug and fully evacuate old oil (tilting the machine ensures complete drainage).
- Flush system (optional): Rinse with fresh oil if severe contamination exists.
- Add new oil: Refill with the specified amount (avoid overfilling).
- Test run: Operate the lift several times, then check oil level and leaks.
- Signs Lubricant Needs Early Replacement
- Oil turns black or murky (severe oxidation).
- Abnormal viscosity (too thin or too thick).
- Increased operational noise (poor lubrication).
Conclusion: Different climates require appropriate lubricants and adjusted replacement cycles. Shorten intervals in hot regions, use cold-grade oils in freezing areas, and ensure long-term equipment reliability!
