Chapter 1: Introduction Weed eaters are a great convenience for a small investment to keep your lawn and landscape looking good. Generally, they will run very well and last a long time if you keep them maintained and treat them properly. As with any tool or equipment there are maintenance and upkeep that need to be completed regularly. The proper fuel mixture used, etc. When something does need repaired or replaced, more often than not, you should be able to do it yourself.
Weed Eaters Weed eaters also known as weed wackers are the most commonly used device for trimming. Weed wackers are devices that are used to cut the grass or weeds near objects easily. If we go into the details of a weed eater you will come to know that weed eaters are made up of handheld elongated pipe that is powered by either electricity or gas depending upon the requirement of the customer.
Chapter 2: Weed Eater Anatomy There are many parts of the weed eaters and every part has its own functionality with the specified utility achieved. Every part is interrelated to the other parts because each part is performing the task with respect to the other components of the weed wackers. The most common functions that we would see in a weed wacker before purchasing is the engine functions that it performs. There should be a few questions in mind before selecting any particular weed wacker.
Trimmer Head As the name suggests trimmer is that part in the wacker that is responsible for cutting the weed from those places where an ordinary machine cannot reach. The concept behind the trim is very simple and unique. Normally in the machines that are used in trimming you must have seen that there are blades used of different metals but in case of the wacker there is not a single blade used in the weed wacker.
length and then load the line with the holes of the head passing from one end to the other end. After that you need to cut the string from the both ends. As soon as you have cut down the string you need to load the line by simply turning up the large knob on the trimmer head. This knob can be managed with the bare hands. When you turn the knob the string comes to the right place you can stop the knob where you want it to.
Trimmer string The trimmer string is that component of the trimmer on which the whole concept of the weed wacker lies within. In earlier times the trimmers that were used to trim the grass or the weed were made of metals and the blades were used for cutting the weed. But as the time passed the concept changed and the technology moved towards the light weight products. These weed wackers has versatility in their design that makes them different from other weed wackers.
available on the market and that could be one the reason of the popularity of the weed wackers. There are different standards of the strings used in the weed wackers. The string should be used onto the recommendation of the company product that you are using. Never try to save the money by using substandard string as it may damage the trimmer as well costing you more in the long run. The catalog is always provided with the product and its maintenance procedures are always mentioned in the manuals as well.
Spool Length The length of the nylon string can range up to few hundred feet. In order to save money, professionals buy 1000 to 2000 foot bulk because they spend hundreds of feet per day. For an average customer, that is not a good idea. If you see 3-pack spools in the shops or large bulks, the first thing on your mind would be: “Is this really an economical purchase, I’ll buy 1000 foot long trimmer line for the next six years!”.
can be even .170 inch thick, which is actually 4.3 millimeter. The trimmer slices through high grass, bushes, ivy and it’s possible to use it on any type of lawn surface, no matter how thick the weeds are. Refilling the spool with proper trimming line means a lot when spending a whole day trimming with Weed eater. Professional gardeners note that it is more important to have quality equipment than to save few bucks and bump the trimmer or replace the line every 10 minutes.
Shaft The shaft is said to be one of those components on which the performance of the weed wacker lies upon. The shaft is kind of mount of which the trimmer head is fixed upon. Many different models of the weed wackers have the ability to have different kinds of attachments. These attachments can be used depending upon the use of the weed wackers.
monitoring. The shaft sometimes may heat due to the excess use or the overload of the weed wacker but you don’t have to worry about the heat. Normally the parts like the shaft have heat emission during use. The shaft can be lubricated using the grease but people often don’t use the phrase instead the lubrication oil is suggested by most of the companies. These lubricants are also available in different forms. Especially the spray oil is widely used by a number of users.
Chapter 3: How To Use A Weed Wacker There are a number of steps followed in using a weed wacker. Obviously there are many different kinds of weed wackers available in the market depending upon the situation of the garden or the area you need to cover. There are some other factors that also influence the choice of the weed wackers as well. We will be discussing all of the factors in this topic as well.
engine should be brought to half position. You have to maintain the throttle as well. As the engine starts running smoothly place the weed wacker on to the direction where you wish to have the weed eaten. There are few other things that need to be adjusted as well. You have to make it sure that the angle of the trimmer is so adjusted that it gives the maximum output. In general practice the trimmer is adjusted thirty degrees.
extra-large then you may cut that into equal parts. Make the loop of the ends that you have already cut. You must know the direction into which you need the twine to be winded. Make it sure that you wind the twine in the right direction. Put the power cord into the power socket and then pull the twine over the cartridge and then you have your engine started. There is a trigger placed on to the weed eater from where you can have the adjustments very easily.
charging is required by the engine to be in full operated form. There are a number of other methods as well. The grip of the handle must be very tight so as to use the weed wacker. There are adjustments present on the handle of the weed wacker so that the person using the weed wacker can have the adjustments accordingly. Many weed wackers have an automatic system of bumping the ground on which they are to be used but some of them have to manage manually by the person handling it.
How To Create The Correct Fuel Mixture For A Weed Wacker We all are familiar with the fact that there has to be some kind of ratio with which the gas and the oil should be mixed in the weed wacker but we need to know that why it is necessary to have the mixing done before the use. In this topic we will cover all the details regarding the mixing technique used in the weed wackers.
Let me explain this fact with the example that if there is no lubrication of the crank space then the heat generated in the crankcase will lower the mobilization of the engine and from that the heat generations will ultimately increase. As the crack is made up of the certain metal and the property of the metal is that it gets an expansion ion heating.
is extremely necessary because it's all about the life of your engine. After you are sure that you have noted down the fuel to oil mixture ratio for your engine then the next step would be the amount of the gas and the oil to be mixed. For example if you are asked to have 30:1 mixture then it means you have to take 30 parts of the gasoline to mix with the only 1 part of the oil. From this one can have an idea about the mixture quantity.
weed wacker to places where you can have the balanced area of the floor or the table. The purpose of choosing the balanced surface is to avoid the fuel not to get wasted, you must have the Kef with you in order to pour the oil into the tank of the weed wacker. Remove the cap of the wed wacker trimmer and use the funnel to pour the gasoline mixture into the trimmer. There is a limitation of the gasoline that can pour into the container.
parts get lubricated it means that there are less chances that the particular part gets over heated. As most of the engine parts are made up of different metals and when the engine is in running form these part do have to move upon each other. According to the laws of friction when the metals move upon each other it not only causing the heat to rise up but there are lots of chances that these metals do get over heated.
How To String A Weed Wacker The string is mounted in the eyelet of the trimmer head. The trimmer head is connected to the shaft of the weed wacker that is responsible for the movement of the weed wacker. Between the guard and the hole of the trimmer you can see the hole openings through which the string has to be passed. First of all never pulls the older string with the force as it's delicately made.
just squeeze the string through the tiny hole and bump several times to reline. Quick feeder is available in shops specialized for gardeners as an additional feature for Weed eater. Force keeps the string taut and it feeds automatically when it becomes worn. 4. Once the spool is wrapped, put it back on the trimmer head. Line the spool with a slot on the head so it could fit in and pull the trimmer line through the socket. Rotate the spool by about 45 degrees, or as much as it can be tightened.
Low quality strings should not be used in the trimmer and only recommended brands should be used in the trimmer. The qualities of the string do have an impact on the working of the trimmer. Lighter weighted good quality string is long lasting and it gives your lawn smoother look that any other string cannot give. The smooth look of the lawn is also dependent upon the person moving the weed wacker.
How To Adjust The Carburetor Of Weed Wacker Carburetors are those kinds of components that should be constantly maintained after some time. There are instructions given in the manuals in which it is clearly written that that after how long the carburetor need to be adjusted again. But the question that comes on to mind here is what does the adjustment mean and how it could be done? All Weed eaters require a carburetor adjustment from time to time.
5. Start the weed eater by pulling the starter cord. The engine will sound out of tune and will fail to idle by itself. therefore apply just enough throttle to keep the engine running. 6. Rotate the LO screw clockwise in one-quarter turn increments checking each time if the engine is idling smoothly. When you have found the sweet position do no further adjustments. Note: For a Video tutorial on how to adjust your Weed Eater Carburetor please follow this link Apply full throttle watching the engine.
wacker and you have reached the carburetor follow the instruction as given in the manual. The carburetor is always located at the lower end of the engine. The carburetor is attached to the number of other things with the engine. Obviously there are fuel pipes attached to the carburetor so as to supply the fuel to the carburetor. There is a term used to call the petcocks with the fuel lines are attached .

wrongly implemented causing the weed whackers to get malfunctioned. As there are lots of components that are attached with the weed wacker including the fuel pump and the engine? The engine consists of many other parts as well. All of these parts are to handle with the specified ways so as to get the weed wacker into the smooth running condition. There are some steps that are necessary to look at before you start the weed wacker. Like the car engines the weed whacker also has a choke in the engine.
The level of the choke means that how much choke is required by the engines. In normal practice the use of the choke is very common in winter season and in the summer season there is no need of the choke to be used, but there is an issue suing the choke excessively as well. When the user uses the chokes without the requirement of the choke to be used then there are chances that the engine might not start or may cause some problems.
of working as well. The basic phenomenon that one must know is that it's all about the fuel reaching to the carburetor without any delay and then the engine will work smoothly. Coming back to the use of the premier bulbs, one must know the fact the primer bulbs have to be pushed before the start of the engine. Now there would be question arising in the mind and that would be why it is always necessary to use the primer bulbs before the starting of the engine? The fuel reservoir will refer to the fuel tank.
if you find it difficult to have those levers seen you can consult the manual as well. The throttle does have a larger role to play. Whenever you start your car you have to give some throttle to start the car similarly while starting the weed wacker engine you also have to make some throttle in order to start the engine.
used. They are effective and cost saving as well if these machines are started the way they are manufactured to be started.
Chapter 4: Common Weed Wacker Faults And Repairs Weed Wacker will not start There could many reasons for having issues in the weed wacker that it could be not starting properly. We will be having discussions in this regard and will try to focus on the issues that may be causing the problems for the weed wacker. To avoid having these kinds of issues there are some steps that are needed to be followed by the user.
Fuel Lines Broken inside tank The fuel lines on a Weed eater are notorious for degrading over time and eventually breaking. The fuel filter located on the small fuel line usually needs replacement by this stage. However this does not mean the end of your weed eater! The small and large fuel lines can be replaced and refitted simply with minor skill involved. The small fuel line is the suction line providing gas to your carburetor from the gas tank.
6. Push the small fuel line into the other hole in the gas tank. Pull this fuel line through the gas tank opening. 7. Put the fuel filter onto the end of the small gas line you just pulled out of the gas tank opening. 8. Pull the small fuel line with attached filter back into the gas tank. 9. Push the other end of the small gas line onto the small carburetor connection. 10. Push the other end of the large gas line onto the large carburetor connection.
The temperature is always high inside the weed wacker engine and the fuel line shave is made of a material that can withstand the temperature inside the engine. The heat inside the engine affects these fuel lines a lot. There is another factor that affects the working of the fuel lines. These fuel lines can be blocked by the fuel that is coming from the fuel tank. There may be involvement of the dust particles in the fuel tank that may cause the fuel line to get blocked.
Non-rotating Trimmer Head The trimmer head on a weed eater will sometimes stop rotating because the rotating mechanism has seized. When this occurs the starter cord will resist and prevent you from starting the engine. If this occurs when the engine is already running the trimmer head will start to smoke when you apply throttle. However this does not mean the end for your weed eater! The rotating mechanism can easily be repaired to allow you to wack those weeds for many more years to come.
8. Refit the bushing assembly to the end of the curved shaft ensuring that you align the assembly correctly with the shaft. Do not use excessive force. 9. Refit the trimmer head Note: For a Video tutorial on how to fix a non-rotating trimmer head please follow this link. There are a number of reasons that can affect the rotating effect of the trimmer head.
problem going on in the weed wacker. There could be numerous reasons that can be the cause of excess vibration. A look at the trimmer head can help you solving this kind of problem.
Snapped Pull Cord on start Assembly Pull cord is the part of the weed wacker that is responsible for starting the weed wacker. The weed wackers that use a pull cord to start the weed wacker are normally available at cheaper rates in the market. There could be various problems that could be faced related to the use of the cord. There are some technicalities in this as well. There is a specific technique that has to be used in order to start the weed wacker using the pull cord.
Weed Wacker will not stay running The weed wackers are those kinds of machines that can bear a lot of pressure of work. It is suggested that the weed wacker should be maintained properly in order to use for the long time. If the weed wacker is used on a constant basis then it means that it had been maintained as well. Now what does that maintenance means? It suggests that every part of the weed wacker should be checked after the use.
Chapter 5: Repair and Maintenance of Weed Wackers You can do many repairs of your weed eater yourself. Sometimes you may need specialized tools, but usually you will only need common tools.
Carburetor Removal and Stripdown A carburetor overhaul and rebuild may be required when you have owned and used your favourite weed eater for some time. Weed wacker carbs contain a number of replacement parts including fuel diaphragms, gaskets, metering needle, primer bulb, fuel lines and filter. The carburetor is a critical part of the weed eater engine and is necessary for providing the correct fuel and air mixture to the engine based on your throttle movements.
9. Check the condition of all the diaphragm gaskets. If a diaphragm gasket is stiff, holed or cracked it will need replacing. It is good practice to replace the diaphragm gaskets every time you overhaul and rebuild your carburetor. 10. Remove the fuel metering needle, metering lever and spring by unscrewing the backing plate bolts. 11. Check the condition of the fuel metering needle. If the tip shows signs of wear or discolouration then it will need to be replaced. 12. Remove the backing plate gasket. 13.
Carburetor Part Replacement and Rebuild Follow the listed steps and video tutorial link below to replace parts and rebuild your Weed eater carburetor: Safety: Do not forget to use safety glasses and gloves 1. Purchase a carburetor kit suitable for your model. Normally two types of kits exist where one kit contains the diaphragm gaskets only and the second kit contains all replacement parts for the carb including the diaphragm gaskets. 2. Refit the metering lever, metering needle and spring.
12. Refit the filter and filter holding plate. 13. Refit the filter cover. 14. Follow the instruction to prime, startup and adjust the carburetor. Note: For a Video tutorial on how to remove and overhaul a carburetor please follow this link.
Compression Test a Weed Eater Engine If a Weed eater has trouble starting and all the usual troubleshooting routes have been explored then the issue may be poor engine compression pressure. The usual non-start routes include gas, fuel lines, carburetor, air filter and spark plug. The piston in the weed eater engine has piston rings that prevent the combustion chamber pressure from escaping past the piston and into the crankcase.
spark plug was screwed into. 6. Watching the compression tester gauge pull the starter cord a number of times until the needle reaches a peak pressure. Note: For a Video tutorial on how to compression test a Weed Eater engine please follow this link. Remember! A weed eater must generate more than 60 PSI or lb. per square inch to be able to start the engine. If your weed eater is less than 60 psi then your engine cylinder has a leak or the piston cannot compress enough air.
Pull cord replacement 1. Buy string/cord in same or slightly larger diameter. 2. Take off plastic cover. You need a hex and a torx driver. Take of green housing. Also take off black handle. 3. The spool is held by clips on a wheel at the bottom. Screws hold the clips tight, just loosen do not remove, turn clips and take out spool. 4. Check path that the string follows, thread string and wrap the same way. Wind string until spool is full. Usually it is about a foot of string. 5.
