    Comments about 20V MAX Lithium-Ion Cordless 12 in. High Performance Trimmer and Edger:

    Great Product for medium duty cutting. For heavy duty like thick weeds & tall grass progress is slow. So convenient I use it for 90% of work in Rural setting. Adjustable length great - I am 6-2 and there is still more extension left in the handle.

    20v max trimmer

    By mouse

    from Houston TX

    Verified Buyer

    Pros

    • Good Price And Good Power
    • Nice looking

    Cons

    • Cutting Not Sharp Enough
    • Squeez All Time No Lock
    • Waste Time Cutting Root

    Best Uses

    • Light trimming

    Comments about 20V MAX Lithium-Ion Cordless 12 in. High Performance Trimmer and Edger:

    overall, it is a very good built product, very good price for two 20v lithium battery trimmer and nice looking as well. but of cause not as powerful and sharp as my gas trimmer. too slow to cut those root node. I will try changing the string to those with edges and see if it would help, a blade the better. I like the roll along wheel, it takes away some weight... if the safety button can lock the power to 'on' at the same time eliminating the squeezing and the motor can tilt up and down that would be perfect.

    • 20V MAX Lithium-Ion Cordless 12 in. High Performance Trimmer and Edger

      Q:

      When I switch from edger to trimmer it does not click and lock in place, but does click and lock in place when I go from trimmer to edger. Is this normal?

        A:

        It should click and lock in place on both going from trimmer to edger as going from edger to trimmer. You might need to push a bit harder when going from edger to trimmer to make sure it locks in place.

      Q:

      I use premium twisted string that is used very quickly. Is there an adjustment for this useage or a description of how to install the string.?
      Asked on 6/3/2015 by Tom from Mount Dora, FL

        A:

        The line feed is automatic, so there is nothing that can be adjusted to feed less line. Here is the description on how to install the string:

        REPLACING THE SPOOL
        • Remove battery from trimmer.
        • Depress the tabs (15) and remove the spool cap (9) from the spool housing (16) in the
        trimmer head (figure M).
        • For best results, replace spool with Black & Decker model # AF-100.
        • Grasp empty spool with one hand and spool housing with other hand and pull spool out.
        • If lever (17) in base of housing becomes dislodged, replace in the position as shown in
        figure N before inserting new spool into housing.
        • Remove any dirt and grass from the spool and housing.
        • Unfasten the end of the cutting line and guide the line into the eyelet (19) figure O.
        • Take the new spool and push it onto the boss (18) (figure N) in the housing. Rotate the
        spool slightly until it is seated. The line should protrude approximately 5-3/8 inches (136mm)
        from the housing. • Align the tabs on the spool cap with the slots (20) in the housing (figure O). • Push the cap onto the housing until it snaps securely into place.
        CAUTION: To avoid trimmer damage, if the cutting line protrudes beyond the trimming
        blade, cut it off so that it just reaches the blade.
        REWINDING SPOOL FROM BULK LINE (use only .065 in. ROUND diameter line)
        Bulk line is also available for purchase from your local retailer. NOTE: Hand wound spools
        from bulk line are likely to become tangled more frequently than Black & Decker factory
        wound spools. For best results, factory wound spools are recommended.
        To install bulk line, follow the steps below:
        • Remove battery from trimmer.
        • Remove the empty spool from the trimmer as described in "REPLACING THE SPOOL".
        • Remove any remaining cutting line from the spool.
        • Make a fold at the end of the cutting line at about 3/4 inch (19mm) (21). Feed the cutting
        line into one of the line anchoring slots (22) as shown in figure P.
        • Insert the 3/4 inch (19mm) end of the bulk line into the hole (23) in the spool adjacent to the
        slot as shown in figure Q. Make sure the line is pulled tight against the spool as shown in
        figure Q.
        • Wind the cutting line onto the spool in the direction of the arrow on the spool. Make sure to
        wind the line on neatly and in layers. Do not crisscross (figure R).
        • When the wound cutting line reaches the recesses (24), cut the line. (figure Q).
        • Fit the spool onto the trimmer as described in "REPLACING THE SPOOL".
