Before inspecting, cleaning, or servicing the machine, shut off engine or motor, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug or disconnect from power supply. Failure to follow these instructions can result in serious personal injury or property damage.


Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury.


When servicing, use replacement parts that meet or exceed original product specifications. Use of any other parts could create a hazard or cause product damage.


See Figures 7 - 8.

For gas and electric power heads, use 0.080 in. or 0.095 in. trimmer line. For cordless power heads, use 0.080 in. trimmer line only.

 Stop the unit and disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect from power supply for electric power heads.

 Rotate the bump knob clockwise as necessary to align the arrows on the bump knob with the arrows on the string head housing.

 Cut one piece of trimmer line 18 ft. long. Insert the line into the eyelet on the string head housing. Push until the end of the line comes out the other side of the housing.

Pull the line until equal amounts of line appear on both sides of the housing.

NOTE: Line may jam if more than 18 ft. is loaded.

 Either by hand or using the Speed Winder™, rotate the bump knob clockwise to wind the line on the spool until approximately 6 in. of line is showing on each side.

NOTE: For best results, after every five to seven revolutions of the Speed Winder™, pull both line ends taut for best loading results and to help prevent line from tangling.


Periodically inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced. Please contact customer service or a qualified service center for assistance.

 Push the bump knob down while pulling on line(s) to manually advance the line.



See Figures 9 - 10.


Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc.


Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which could result in serious personal injury.

 Stop the unit and disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect from power supply for electric power heads.

 Depress the tabs on the side of the string head housing to remove the lower string head housing.

NOTE: The housing is spring loaded and will self eject when the tabs are depressed. It is not necessary to remove the upper string head housing from the drive shaft.

 Push the spool and bump knob through the string head housing and remove the string from the spool.

 If replacing the bump knob, remove the old knob from the spool. Align the knob ribs with the spool slots and place the new bump knob onto the spool. If you are not replacing the bump knob, skip this step.

 Insert the bump knob and spool assembly through the opening in the string head housing.

 Align the slots on the lower string head housing with the tabs on the upper string head housing.

 Push the housing together until the tabs snap into place.

NOTE: Hold the spool by the knob while completing the installation.

 Install line as described in Line replacement.
