Simple maintenance tasks help get the most out of portable generators.
PORTABLE GENERATORS ARE VIRTUALLY INDESTRUCTIBLE. Aside from throwing one off a cliff, there isn't much an operator can do that will completely wreck a generator. However, there are a few simple steps to take that can help extend the life of a portable generator. Generator maintenance basically boils down to taking care of the engine and paying attention to safety procedures. By adhering to a maintenance schedule, keeping track of vital maintenance information and operating as recommended, operators can help ensure that their portable generators will last longer, making it a valuable addition to any fleet for many years.
Fuel School
ONE OF THE MOST COMMON problems associated with generators is dirty fuel and the effects it has on a generator engine. Dirty fuel is a result of improper fuel storage or refilling tanks in dusty conditions. If operators don't take the time to prevent dirty fuel, they can run into problems with clogged fuel lines and carburetors, which can be expensive to replace.
To prevent dirty fuel from entering a generator, store fuel in an OSHA-approved receptacle and keep it out of high traffic areas where dust and debris can contaminate. When refilling, there are a few simple steps to take that can help extend the life of a portable generator. Move the generator out of windy conditions where dust is more likely to enter the fuel tank.
In addition to keeping the fuel clean, it is important to refill under proper conditions. Adding fuel while the unit is running is extremely hazardous. Gasoline vapors can ignite when they come in contact with hot components such as the muffler, exhaust fumes or an electrical spark, resulting in an explosion that will not only severely damage the generator, but also cause serious harm to the operator. To prevent such a disaster, shut the generator down and allow ample cooling time before refilling.
Another hazard associated with fuel is overfilling. Spilled fuel poses the same threat as fuel vapors when exposed to hot surfaces and electric sparks. To prevent spillage, keep the fuel level to one-half inch below the tip of the fuel tank. If a spill occurs when refilling, replace and tighten the cap and move the generator away from the spill before starting it.
Oil Toils
ADEQUATE LUBRICATION is just as essential to generator engines as clean fuel. Maintaining the proper oil level is crucial. For a frequently used generator, engine oil should be checked before each use and topped off as needed.
Oil changes should take place according to the schedule in the generator owner's manual, usually every 50 to 100 hours, depending on usage. If your generator does not come equipped
