Machine Leaf Blower
A leaf blower is an equipment which propels air out of a nozzle to blow away unwanted materials―mostly fallen leaves―in the lawn. It is most often used to clear the lawn of dry leaves and hence, is referred to as a leaf blower.
Man Using Leaf Blower
This self-contained equipment is usually hand-held, but some units are designed to be carried on the back as a backpack, with the wand blowing air to be held in the hand.
These blowers are usually powered by a two-stroke engine, but concerns raised by environmentalists have made the manufacturers come up with models powered by a four-stroke engine. The air blows at a speed of 180 miles per hour from this machine and blows dry leaves away, thus clearing your beautiful lawn.
Guide to the Diagnosis and Repair of a Leaf Blower
The mechanical problems with your leaf blower may range from a simple vacuum tube clogging to impeller malfunctioning. It's repair though, doesn't require much of a technical expertise.
One of the most common problems which you are likely to encounter is that of vacuum tube clogging, wherein grass or such material goes inside the vacuum tube and chokes it. In such a case, you are required to remove the tube to clean it. If you see any debris stuck inside it, get rid of the same and clean the tube properly.
Sometimes, you may notice your leaf blower making too much of noise or vibrating. The problem here might be some loose part that needs to be fixed. Check all the components of the blower (and also the screws which connect them) and fix them if need be.
Starting Problem
In many cases, power problem is the main reason for leaf blower not starting. If it's a gas-powered equipment, check whether there is enough gas and refill if necessary. If it's an electric leaf blower, check all the cords, switches, and power outlets.
If you feel any of these components are worn out, you should replace them with new parts. If all these components are in good condition, but still your leaf blower is not working, then it may be a motor problem or some engine malfunctioning. In this case, it is better to seek professional help instead of trying your hand at repairs.
Over the period, you may notice that the performance of machine diminishes, which is usually the case of a faulty impeller. The impeller draws air into the machine and blasts it through the blower tube at a tremendous speed. If the impeller housing is cracked, it has to be repaired, as it hampers the machine's performance.
In case of a cracked impeller housing, you will have to clean the affected area with a brake cleaner and rough it up using a sandpaper. Fill the area with metal-impregnated epoxy or fiberglass resin, and allow it to dry. Once the filling dries, smooth up the rough area.
If the impeller has worn out, you will need to replace it with a new one. To replace the impeller you will have to open the leaf blower. Wear gloves and remove the impeller using a socket wrench to keep it steady. Replace the worn out part with a new one with the same specifications and reassemble it.
Leaf blower is a must-have equipment, if you want to keep your garden free of dry leaves. While proper maintenance can help you ensure a long life for it, knowing the basics of its repair is an added advantage.
