Use Quality Fuel and Fluids

Choose the Right Diesel Fuel

Pick the right diesel fuel for your generator. Longkai says to use only high-quality fuel and fluids. This keeps all generator parts safe. Good fuel helps your generator run well and last longer. Bad fuel lets dirt and water get inside the engine. This can hurt the engine and make it break down sooner.

Here are some good things about using high-quality diesel fuel:

• You use less fuel because it works better.

• The generator lasts longer with less damage.

• You get steady power, even when things are hard.

• Better fuel makes less pollution and helps the environment.

Tip: Always get diesel fuel from trusted places. Keep fuel in clean tanks so water and dirt stay out.

Use Recommended Oils and Coolants

Use the oils and coolants that Longkai says are best. These fluids help your generator work well and protect key parts. Engine oil helps parts move easily. It cuts down on rubbing and stops them from wearing out. Coolant keeps the engine at a safe temperature. It stops the engine from getting too hot and keeps the radiator from rusting.

Here are some reasons to use the right oils and coolants:

• Engine oil gives good protection and lowers rubbing.

• Coolant keeps the engine cool and stops it from overheating.

• The cooling system works best when you check coolant and keep the right mix.

• Both fluids stop rust and help the generator last longer.

Note: Check oil and coolant often. Change them when Longkai says to in the manual. Doing this helps your generator stay strong for a long time.

Keep Filters Clean

Air Filter Care

You need to keep the air filter clean to help your generator work well. A clean air filter lets the engine breathe easily. When the air filter gets dirty, problems start to appear. Here is what can happen if you ignore the air filter:

• Overheating can occur because the engine cannot get enough air. The engine runs hotter and parts may get damaged.

• Engine wear and tear increases. Dirt and dust slip past a clogged filter and reach the engine. Pistons, cylinders, and bearings wear out faster.

• Fuel consumption goes up. The engine uses more fuel to make the same power, which costs you more money.

You should check the air filter often. If you see dirt or dust, clean or replace it right away. Longkai designs their generators so you can reach the air filter quickly. This makes your job easier and helps the engine last longer.

Tip: Clean the air filter every time you do a routine check. Replace it if you notice damage or heavy dirt.

Fuel and Oil Filter Replacement

Fuel and oil filters protect your generator from harmful particles. Clean filters keep the engine running smoothly and stop damage before it starts. You should follow these simple rules for changing filters:

• Change the fuel filter every 100 to 200 hours of use or once a year. If you use diesel fuel, you may need to change it more often.

• If you run your generator in a dusty place, check and change filters more often.

• Change the oil after 50 to 100 hours of running time. The first oil change should happen at 25 hours.

Clean filters help your generator stay strong and reliable. If you keep up with filter care, you save money and avoid sudden breakdowns.

Note: Always use the filters recommended by Longkai. This helps protect your engine and keeps your warranty safe.

Manage Load Levels

Avoid Overloading

You must not let your generator work too hard. If you put too much load on it, the inside gets hot fast. Every time the temperature goes up by 10 degrees Celsius, the parts lose half their life. Running at high temperatures makes the generator wear out faster. Each hour at high heat can take away two hours of life. Overloading also makes the engine and alternator break down sooner. Other parts can get damaged too. You might have sudden stops or need costly repairs. If your generator stops during important jobs, your business can lose money and time.

Tip: Check the load before you start your generator. Make sure the power needed does not go over the rated limit. If you see warning lights or hear strange sounds, lower the load right away.

Here is a simple table to show safe load levels:

Balance Power Demand

You should keep the power demand balanced. This helps your generator work better. If you keep the load close to the rated capacity, the engine runs well. You use less fuel and save money. If the load is too low, the generator wastes fuel. Costs go up when this happens. Try to match the power demand with what the generator can handle.

1. A higher load factor means the generator works near its rated power. This helps the engine use fuel wisely.

2. A lower load factor means the generator runs below its rated power. This leads to wasted fuel and higher costs.

Note: Plan your power needs before you start the generator. Spread out heavy tasks so the load stays steady. This helps all parts last longer and keeps your power supply strong.

Proper Installation and Sizing

Match Generator Size to Needs

You must choose a generator that fits your power needs. If you pick a size that is too small, you risk overloading and damaging parts. If you pick a size that is too large, you waste fuel and money. You should look at your power demand and plan for future growth. Here are some things you need to think about:

• Load uncertainty can make sizing hard. You should list all the devices you want to power.

• Load growth matters. If you plan to add more equipment, choose a generator that can handle extra load.

• Check your past power use. This helps you know how much energy you need.

• Motor starting can cause dips in frequency. Make sure your generator can handle these changes.

• Harmonics from non-linear loads can affect performance. You may need a harmonic analysis.

• New technology like IGBT rectifiers and soft starters can create noise or voltage issues.

• If you use VFDs or UPS systems, size your generator to manage their special needs.

Tip: Always ask for help if you are unsure about sizing. A well-sized generator works better and lasts longer.
