• How to find the right trimmer line
    There has many different line weights and diameters of trimmer lines. Each trimmer can only handle a certain line diameter, kindly check your trimmer’s manual for specific recommendations firstly. A larger diameter will increase your cutting power and durability against thicker grasses and weeds. A lighter weight should be used on areas where there are a minimum of weeds.

    Light Work: Residential front and back lawns with lighter weeds.

    Medium Work: Larger back and front lawns or lawns with heavier weeds and light commercial work.

    Heavy work: Industrial landscaping, large yards, golf courses and other areas that need a large amount of trimming.

    Diameter Size:

    Light-medium work: 0.65 inches – 0.80 inches

    Medium-heavy work: 0.85 inches – 0.105 inches

    Very heavy work: 0.110+ inches

  • How do I change the trimmer line?

    There are five ways to change trimmer line depending upon the style of trimmer head on your unit.

    The first style has a locking tab on the side of the trimmer head that must be depressed while the lock ring is turned counter-clockwise. This will remove the cover and give access to the spool which can then be pulled out, rewound with the line (winding in the direction of the arrows on the spool), and re-installed.

    The second style requires lining up the marks on the bottom of the spool tap/button assembly and firmly pulling straight out on the tap button. This pulls the spool assembly out so it can be re-wound and inserted back into the hub assembly.

    The third style requires pushing in and down on the two locking tabs on the side of the trimmer head. This will remove the cover and give you access to the spool.

    The fourth style of trimmer head is the Centrex. Remove the cap on the bottom of the head by unscrewing it. Remove the guide ring and remove the spool from the unit. Cut a 25ft length of line and insert one end into the center cavity of the empty spool. Feed the line into the spool, leaving 4-6 inches unwound from the center of the spool. Reinstall the spool, guide and cap, making sure the notch in the guide is facing away from the spool and the line is in the notch.

    The fifth style is the fixed line cutting head. This style cutting head uses a pre-cut piece of cutting line. After removing the worn line from the cutting head, insert the precut piece into the positioning tunnel leaving an equal amount out each side of the tunnel. The ends of the line can then be inserted through the exit tunnels.

    Cutting line or pre-wound spools are available at most retailers that sell Weed Eater product.

  • Why does the trimmer line break?
    Trimmer line usually breaks because of line crowding. This occurs when the trimmer head is held too close to hard objects that can break the line such as brick, cement, rocks, or fencing. Keeping the line at full extension, and not crowding it, reduces line breakage problems.
  • How Do I Operate the Trimmer?

    Trimmer operation takes a little practice to get used to counterbalancing your weight with the cutting head. For this reason, only trim in dry conditions with closed-toed shoes. Always keep the cutting head parallel to the ground, and use the tip of the line to cut the grass, easing it into and out of the cutting area. Try to work from right to left so that all debris, including rocks, get flung out through the cutting shield and away from the operator. Cut grasses taller than 8 inches from the top down, and always keep the line at full length.

  • Why Won't the Trimmer Start?
    Most starting problems relate to the fuel systems on these trimmers. Carbon deposits will gradually build up in the cylinder, carburetor and fuel lines, suffocating the engine of fuel. When the trimmer won’t start, always check the tank to ensure there is a fresh supply of mixed fuel. Dump out any fuel older than one week, and replace the fuel filter and fuel lines every season, which will prevent most gas problems. For carburetor help, take the trimmer to a professional to have it cleaned every couple of seasons.
  • How do I Install the Spool?
    Installing the Spool:Holding the line and spool, insert the spool into the cutting head and the line into the eyelet.Holding the line and spool, place the cap over the spool.Twist the cap on securely by turning clockwise.If the line should tangle or break at the eyelet, stop the trimmer, remove the spool as described above, feed the line through the eyelet, and reassemble the spool to the cutting head.


  • What’s the Trimmer Line’s Styles?

    Round Trimmer Line: Round Trimmer line is the standard, basic shape that won’t wear down as quickly as other trimmer lines. These trimmer lines are used for lighter, residential use with minimum weeds. Round trimmer line breaks less and is more durable against concrete, trees and etc. to give you an extended use time. This is also the easiest trimmer line to replace in your trimmer. –


    Multi-sided Trimmer Line: Multi-sided trimmer lines have multiple sides that produce a cleaner cut. These lines commonly come in the shape of a star, square or pentagon. These trimmer lines slice through heavy weeds and thick grass quickly and efficiently, giving you an even cut in less time. However, multi-sided trimmer lines break easy when they come in contact with stones, fences, curbs, sidewalks and etc. Some common multi-sided trimmer lines are: Gatorline, Magnum Gator Line, Nylium Starline, The Edge, Trim Force, and much more.


    Serrated Trimmer line: With edges that act like teeth or a kitchen knife, this serrated line can quickly saw through grass blades and thick leaves, leaving a cleaner trim. This trimmer line has extra cutting power and can be used for medium-heavy jobs. A serrated trimmer line can cut through weeds easily and quickly to keep your trimming time at a minimum. Flexiblade is a commonly used serrated trimmer line.


    Twisted Trimmer Line: Twisted Trimmer line adds strength, improved efficiency and reduces noise levels. This line is a step up from the round style line and offers durability when hitting concrete or hard surfaces. This trimmer line can reduce trimmer vibrations and noise levels while giving you a clean, even cut. Some commonly used twisted trimmer lines are: Platinum Gatorline, Super Twist Magnum Gatorline, and much more.

  • Why does the line on my electric trimmer keep snapping?

    Ensure that genuine Flymo trimmer line is being used. Frequent line breakage is usually the result of the cutting head being taken too close to objects, i.e. walls, paving edges, etc. The cutting line must be allowed to rotate freely and the correct diameter line should be used.

  • What kind of trimmer line should I use?
    • With four sharp edges, square trimmer line cuts faster and more efficiently. The square-edged line works well if you have tall, thick and heavy patches of weeds. The downside to square line is it breaks off quicker when it contacts stones, fences, curbs and buildings. Square line also has a tendency to jam in the spool retainer if the line isn’t replaced properly.
    • Round trimmer line is smooth and will wear down less quickly. Most cutting occurs at the very tip of the line, so when round line contacts hard surfaces, like sidewalks or trees, it will break off less. The round line is also simpler to load into the spool retainer during line replacement, which may save time in the long run if you have a lot to trim.
    Hex (aka Star)
    • The Hex (star) or multi-sided line uses this shape to make cutting even faster. Again, the same rules apply with the square model string: quicker cutting but faster wear.Diameter
    • All of the lines come in a wide variety of diameters. Industry standard on most models is .080 millimeters. This diameter measures the thickness of the line. If you’re having problems with the square line breaking too quickly, you may increase the diameter size one increment. If, on the other hand, your line is jamming or fusing together inside the spool retainer, you can reduce the line size by one notch. Check with your owner’s manual for maximum line diameter; overloading can damage the drive shaft.Considerations
    • Square trimmer line is quite similar to round trimmer line, and it really comes down to preference and feel. Their difference lies in the amount they will wear out. Consider how much you need to use the trimmer, over what physical conditions, how long each job will take you and how often you will need to replace your line. Both lines are relatively inexpensive, so you can experiment for the best results.
