How to fix a DEK 7550EL Pro Inverter when it won't start?
If your DEK Inverter engine won't start, several factors could be at play. First, ensure the fuel valve is on and the tank isn't empty; if not, fill the tank and turn the valve on. Check the spark arrestor for clogs and clean it if necessary. Make sure the choke is closed during starting, and open it afterward. A failed vacuum check valve, a broken on/off switch, or low oil level can also prevent starting. Verify the oil switch/sensor functionality. Additionally, inspect the fuel filter and spark plug for dirt or damage, cleaning or replacing them as needed. Lastly, a clogged carburetor might be the culprit, requiring cleaning with fresh fuel.
Why is oil leaking from the valve head cover on my DEK 7550EL Pro?
If oil is leaking from the valve head cover of your DEK Inverter, the bolts might not be tight enough. Tighten the bolts to resolve the leak.
Why is fuel leaking at the tank shut-off of my DEK 7550EL Pro?
If you notice a fuel leak at the tank shut-off of your DEK Inverter, the shut-off valve might be loose. Try tightening the nut on the shut-off valve. If that doesn't solve the problem, consider replacing the shut-off valve.
Why is my DEK 7550EL Pro leaking engine oil?
If your DEK Inverter is leaking engine oil, check for leaks from the crankcase. If the oil is leaking from crankcase, tighten the crankcase bolts. If the oil is leaking from the shaft, it may indicate that the oil seals have failed.
Why is fuel leaking from my DEK 7550EL Pro Inverter's carburetor?
If fuel is leaking out of the carburetor of your DEK Inverter, the fuel drain screw might be loose; tighten it. Alternatively, the carburetor float seat may not be seating properly; flush it with clean fuel.
Why is my DEK 7550EL Pro Inverter engine running rough?
If your DEK Inverter engine runs roughly, vibrates, or oscillates, here are some potential causes and solutions: Ensure the choke is fully open by pushing the choke lever in. Reduce the load on the generator by disconnecting some appliances if you're overloading it. Check the air filter and clean it if it's dirty. A clogged fuel filter can also cause this issue, so clean it. If the vacuum check valve has failed, replace it. If the head valve timing is off, it is recommended to send it to a service center.
What to do if DEK 7550EL Pro starts then shuts off quickly?
If your DEK Inverter engine starts but shuts off quickly, check the following: Ensure the oil level is adequate by consulting the owner's manual for the correct oil capacity. Verify that the fuel valve is open and the tank isn't empty. Inspect the spark plug for fouling or failure, and clean or replace it as necessary. A failed vacuum check valve could also be the problem; replace it, and call DEK for the replacement procedure.
DEK 7550EL Pro Inverter shows voltage but no power to devices, what's wrong?
If your DEK Inverter shows both 240VAC and 120VAC on the voltmeter, but connected devices aren't receiving power, here's what you can check: First, try a different extension cord or power strip, as the current one may be faulty. Ensure the device you're using hasn't failed by testing with a different light bulb or device. Also, verify that the push-button breaker hasn't tripped. Finally, check the GFCI; if it's tripped, push the red reset button firmly, and if it has failed, replace it with any standard GFCI or household outlet.
Why does my DEK Inverter engine bog down under load?
If your DEK Inverter engine runs but bogs down under load, consider these potential causes: The choke might be open, so push the choke lever in. You might be overloading the generator, in which case you should disconnect some appliances or devices. A dirty air filter or a clogged fuel filter could also be the culprit, so clean the air filter and clean the fuel filter.
