Generator on High Pressure Hot Water Skid Units

Your generator gives electricity off of 110 volts at a power of 30 amps. Thirty amps is a lot of power and should be ample for all your needs while doing pressure washing. About the same power as a motor home generator or an 11 hp Honda or Onan generator. That's plenty for you to run a vacuum, reclaim device, lights and the burner motor at the same time.
Make sure your belt on your generator is always tight.
If it breaks, take in the old one to match the size at any auto parts store, since the. Check the terminals on the generator every once in a while. Remove the ground wires and sand down the connection points. Working around water can cause the metal to rust and you won't get a good ground. Eventually this will cause premature failure of the generator.
Other stuff that you should know:
Do not adjust belts or try to change them when the engine is running
Do not touch the generator when the machine is in use
Disconnect the battery when doing any routine maintenance on the generator
Do not spray the pressure washers directly on to the generator while it is running
Keep the generator dry, at all times
If your burner stops working it could from the generator not producing electricity, in this case check and make sure the belt is tight, not slipping from being wet and that the burner cord is plugged in. Then check the relay switch or the fuse, often the circuit breaker fuse will pop from being over loaded or the belt slipping from rain water or a leaky unloader.
If your generator smells it could be toast, you can keep working with cold water but your results will not be so good. Generators are expensive about $600 for a new one. If you replace it make sure the new one has two main bearings not only one, the life expectancy is five times longer and they are worth the extra money. If you are out on a remote jobs site such as cleaning oil field equipment have a spare, you will be glad one day you had an extra on truck.
Stay up on the preventative maintenance of your generator as it is an integral part of your hot water pressure washer. Without it, you cannot make as much money. Think about it.
