While leaf blowers may not be the most complex pieces of electrical/gasoline equipment, they do come into contact with a lot of leaves, branches and dirt in day-to-day use. This can cause the unit to clog up or wear out quickly if it is not regularly checked and maintained. While the maintenance procedures for different types of leaf blowers vary to some degree, the basic contours are more or less the same. That said, you should note that the gas blowers have a somewhat lengthier maintenance list compared to an electric blower and as such, some steps that may apply to the former may not be relevant for the latter. In the following maintenance guide therefore, we have marked the steps that are necessary only for gas leaf blowers.
Check and Clean the Air Filter (Daily)
The air filter consists of a rectangular piece of porous material that removes the dust in the air passing through it. Check the air filter by unscrewing the air filter shield or socket and pulling it out. Pull out the air filter and notice whether the white surface has any black/greyish sediment. Wipe off with a dry cleaner or cloth and replace it in the unit.
Check and Fix The Starter Apparatus (Weekly)
One of the few electrical components that can wear out over time, starters are vital to ensuring that the flow of electricity occurs properly. Generally, it is composed of three components – device, tension spring and cord. Unscrew all three from their sockets and check for buildup of any oil or dirt on them. Further, note whether the connections and springs are in good shape. If there is excess oil, wipe it off. If the springs, etc. are damaged, however, you would probably have to replace the starter component.
Note : Do not try to repair any of the starter components. All three are cheap and are easily available in local shops.
Throttle Lock and Throttle Trigger (Weekly)
The lock and trigger mechanism can become loose or wear out over time due to repeated use. Check the status of throttle lock and associated trigger carefully and replace the parts if either appears worn out.
Clean carburettor, spark plug and fan blades (Weekly)
A carburettor is generally found only in gasoline-based units while the other two are common to all models of leaf blowers. If you own a gasoline unit, clean out the carburettor first and then proceed to wipe the outside of the spark plug with a dry cloth. If you have an electric blower, proceed directly to the plug and then to the fan. You may want to use canned air to remove some of the more tenacious dirt. Avoid using liquid detergents however as these may leak into the electrical components and cause malfunctions.
Change the Fuel in the Tank (Monthly)
Required only for gasoline leaf blowers, this step ensures that there is always sufficient fuel available in the tank and furthermore, the quality of the fuel is maintained. Before draining out the fuel, keep the machine turned off for at least half an hour. Connect a funnel to the mouth of the tank and empty out the fuel into a container. Do not use this spent fuel for any purpose –send it to the recycling plant instead.
Connect the funnel to a tank of fresh fuel and gently pour out a sufficient quantity into the fuel tank. Close the tank and run the machine for a couple of minutes to check whether the new fuel is being carried properly.
Along with the above steps, you would also need to wipe the interior and exterior of your leaf blowing tubing to the greatest extent possible. Further, tightening of screws and cleaning the exterior of the device at regular intervals is also needed in order to maintain the functionality and looks of the machine. Combined with the above steps, these leaf blower maintenance procedures should provide enough security against the wear and tear involved in regular operation.
