As a supplier of construction diesel generators, I understand the critical importance of proper storage for these valuable assets. Construction diesel generators are essential equipment on job sites, providing reliable power for various construction activities. However, improper storage can lead to a range of issues, from mechanical failures to reduced lifespan. In this blog, I will discuss the key requirements for the storage of a construction diesel generator.
1. Location Selection
The first step in storing a construction diesel generator is to choose an appropriate location. The storage area should be dry, well - ventilated, and protected from the elements. A dedicated storage shed or a climate - controlled warehouse is ideal. Exposure to moisture can cause rust and corrosion on the generator's metal components, such as the engine block, fuel tank, and electrical wiring.
- Dryness: Moisture is the enemy of diesel generators. Water can seep into the engine, fuel system, and electrical components, leading to rust, short - circuits, and fuel contamination. A dry storage location helps prevent these problems. For example, if a generator is stored in a damp area, the water can cause the fuel to emulsify, which can clog the fuel injectors and reduce engine performance.
- Ventilation: Adequate ventilation is crucial to prevent the buildup of harmful gases, such as carbon monoxide. Diesel generators produce exhaust gases during operation, and even when not in use, small amounts of fumes can be released. A well - ventilated storage area ensures that these gases are dispersed, reducing the risk of poisoning and damage to the generator.
- Protection from the Elements: The storage area should be protected from rain, snow, and direct sunlight. UV rays from the sun can damage the generator's paint and plastic components, while rain and snow can cause water damage. A covered storage area or a generator enclosure can provide the necessary protection.
2. Cleaning and Maintenance Before Storage
Before storing the construction diesel generator, it is essential to perform a thorough cleaning and maintenance routine.
- External Cleaning: Clean the exterior of the generator to remove dirt, dust, and debris. Use a mild detergent and a soft brush to clean the surfaces. Pay special attention to the air intake and exhaust areas, as these can become clogged with dirt, which can affect the generator's performance.
- Internal Cleaning: Drain the fuel tank and clean it to remove any sediment or contaminants. Change the oil and oil filter to prevent the buildup of sludge. Inspect the coolant level and quality, and replace it if necessary. A clean internal system helps prevent corrosion and ensures that the generator is ready for use when needed.
- Inspection: Conduct a detailed inspection of the generator's components, including the belts, hoses, and electrical connections. Look for signs of wear, damage, or loose connections. Tighten any loose bolts and replace any worn - out parts.
3. Fuel Storage and Treatment
Proper fuel storage is a critical aspect of generator storage. Diesel fuel can degrade over time, especially when exposed to air, water, and heat.
- Fuel Stabilization: Add a fuel stabilizer to the diesel fuel before storage. A fuel stabilizer helps prevent oxidation and the growth of microorganisms in the fuel. This ensures that the fuel remains in good condition during storage and is ready for use when the generator is started up again.
- Fuel Level: Fill the fuel tank to about 90% capacity. This reduces the amount of air in the tank, which helps prevent fuel oxidation. However, do not overfill the tank, as fuel can expand when heated.
- Fuel Tank Maintenance: Regularly inspect the fuel tank for leaks and corrosion. If any issues are found, repair them immediately to prevent fuel loss and contamination.
4. Battery Maintenance
The battery is an essential component of a construction diesel generator, as it provides the power to start the engine.


- Battery Charging: Before storage, fully charge the battery. A fully charged battery is less likely to sulfonate, which can reduce its lifespan. Consider using a battery maintainer or a trickle charger to keep the battery charged during storage.
- Battery Disconnection: If possible, disconnect the battery from the generator during storage. This helps prevent battery drain and reduces the risk of electrical shorts. Store the battery in a cool, dry place.
5. Lubrication
Proper lubrication is vital for the smooth operation of the generator's engine.
- Engine Oil: As mentioned earlier, change the engine oil before storage. The new oil provides a protective layer on the engine's internal components, preventing corrosion and wear.
- Other Lubrication Points: Lubricate other moving parts, such as the generator's bearings and shafts. This helps prevent rust and ensures that the parts move freely when the generator is started up again.
6. Covering and Securing
Once the generator is cleaned, maintained, and prepared for storage, it should be covered and secured.
- Generator Cover: Use a high - quality generator cover to protect the generator from dust, dirt, and moisture. The cover should be made of a durable, waterproof material and fit the generator properly.
- Securing the Generator: Secure the generator to prevent it from being moved or damaged. This can be done by using straps or chains to anchor the generator to a stable surface.
7. Regular Inspections During Storage
Even when the generator is in storage, it is important to conduct regular inspections.
- Visual Inspections: Check the generator for any signs of damage, such as rust, leaks, or loose parts. Inspect the fuel tank, battery, and electrical connections.
- Functional Checks: Periodically start the generator for a short period to ensure that it is still in working condition. This helps prevent the engine from seizing up and keeps the components lubricated.
8. Documentation
Keep detailed records of the generator's storage, including the date of storage, maintenance activities, and inspection results. This documentation can be useful for future reference and can help ensure that the generator is properly maintained.
In conclusion, proper storage of a construction diesel generator is essential to ensure its reliability and longevity. By following these requirements, you can protect your generator from damage and ensure that it is ready for use when needed.
