MAINTENANCE WARNING: 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. WARNING: 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.  Cut one piece of trimmer line 10 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 10 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.  Push the bump knob down while pulling on line(s) to manually advance the line. WARNING: When servicing, use only recommended or equivalent replacement parts. Use of any other parts could create a hazard or cause product damage. NOTICE: 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. CLEARING LINE JAM AND/OR REPLACING BUMP KNOB See Figures 10 - 11.  Stop the engine or motor, disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect the plug from the power source for electric power heads.  Rotate the lower housing counterclockwise so the arrow on the upper housing aligns with the outside arrow on the bump feed housing. NOTE: The housing is spring loaded and will self eject when unlocked. It is not necessary to remove the upper string head housing from the drive shaft. GENERAL MAINTENANCE 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.  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. WARNING:  Insert the bump knob and spool assembly through the opening in the string head housing. 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. LINE REPLACEMENT See Figures 8 - 9. Use original manufacturer's replacement line for best performance.  Stop the engine or motor, disconnect the spark plug wire for gas power heads, remove the battery pack for cordless power heads, or disconnect the plug from the power source for electric power heads.  R otate the bump knob clockwise as necessary to align the arrows on the bump knob with the arrows on the string head housing.  Align the arrows on the lower string head housing with the arrows on the upper string head housing.  Push the housing together and rotate the lower housing clockwise until the arrows on the lower housing are aligned with the lock on the upper housing.  Install line as described in Line Replacement. ATTACHING THE STORAGE HANGER See Figure 12. There are two ways to hang the attachment for storage.  To use the hanger cap, push in the button and place the hang- er cap over the end of the attachment shaft. Slightly rotate the cap from side to side until the button locks into place.  The secondary hole in the attachment shaft can be used for hanging purposes as well. 8 - English
