Key Maintenance Points For LGMA Compact Wheel Loaders In Summer
With the persistent high temperatures and dry, dusty conditions of summer, wheel loaders face severe thermal stress during heavy-duty outdoor operations. To help users worldwide ensure uninterrupted operation during the summer heat, LGMA has released the following key summer maintenance guidelines for the core systems of its wheel loaders.
Selecting the Right Hydraulic Fluid and Gear Oil
The top priority for summer maintenance is to prevent lubrication failure caused by fluids thinning due to high temperatures.
Drive Axle Management: For LGMA wheel loaders, check the gear oil for deterioration during the summer. High temperatures accelerate oil oxidation, and maintaining clean oil is key to protecting drive axle components.
Fuel Management: Summer conditions are dry and dusty, making it easy for dust particles to mix into the diesel fuel. Regularly drain accumulated water and impurities from the bottom of the fuel pre-filter.
Intake and Cooling System Protection
Cooling System Operational Recommendations: At the end of each workday, after the machine has cooled down slightly, thoroughly clean any debris accumulated around the high-level radiator to ensure the aerodynamic passages are completely unobstructed.
Air Filter Maintenance Maintenance Details: Remove coarse particles from the bottom of the air filter. When cleaning the paper fine filter element, use dry compressed air to blow it out in a circular motion from the inside out.
System Protection After Startup and Shutdown
Smooth Transition After Startup
Operating Recommendations: After starting, let the engine idle for 3–5 minutes while monitoring the coolant temperature gauge and hydraulic oil temperature gauge. Then, perform several full-stroke, light-load movements with the boom and bucket. Wait until the system reaches a stable operating temperature before proceeding to heavy-load operations.
Cooling-Down Procedure Before Shutdown
Operating Recommendations: After completing work, let the engine idle for about 5 minutes to allow LGMA high-efficiency fan to circulate and dissipate residual internal heat.
Environment Selection and Electrical Protection
Storage Location: Park LGMA wheel loaders in a flat, solid, and shaded area whenever possible. Prolonged exposure to direct sunlight will accelerate the aging of hydraulic hoses and seals.
Electrical Inspection: Since summers are often rainy and humid, inspect all electrical connectors on the vehicle to prevent short circuits caused by high temperatures that can make wire insulation brittle.
Frequently Asked Questions
Q1: How does the summer storage environment affect the electrical system of a wheel loader?
A1: Prolonged exposure to direct sunlight accelerates cracking in hydraulic hoses and causes the insulation on electrical wiring to become brittle. Additionally, since summers are rainy and humid, parking in low-lying areas prone to water accumulation can allow moisture to seep into electrical connectors, leading to oxidation and corrosion, which increases contact resistance and may even cause short circuits. Choosing a cool, dry storage location and regularly inspecting connectors are key to ensuring electrical safety during the summer.
Q2: Which areas should be prioritized during the “three-minute inspection” before starting work in the summer?
A2: Before starting the machine each day, it is recommended to conduct a comprehensive visual inspection: check the tires for abnormal cracks or embedded sharp objects; ensure the surfaces of the piston rods on all hydraulic cylinders are clean; and verify the oil and coolant levels throughout the machine. This quick inspection can promptly eliminate potential risks and ensure that LGMA wheel loaders perform reliably during heavy-duty operations.
Summary
By performing scientific and professional preventive maintenance on the cooling, sealing, filtration, and drive systems during the summer, LGMA can maximize the durability potential of its wheel loaders and maintain high operational efficiency even in sweltering conditions.
