LINE AND BLADE REPLACEMENT
See Figures 12 - 15.
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.
When using the bump feed trimmer head:
 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 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 spool 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 spool 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.
When using line in the fixed line/blade housing:
 Remove old line from the string head by pulling one side
of the line.
 Fold an 11 in. piece of pre-cut line in half so each half is
equal in length.
 Insert the ends of the line through the eyelet in the post
and pull tight.
 Repeat wth the other post.
When using blades in the fixed line/blade housing:
 Remove the fixed line/blade housing by rotating the lower
housing counterclockwise so the posts and the arrows
on the upper housing align, then pull the lower housing
away from the upper housing.
 Remove the used blades and discard.
 Install the new blades, making sure they are fully seated.
 Reinstall the fixed line/blade housing as previously
d escribed.
CLEARING BUMP FEED TRIMMER HEAD LINE
JAM AND/OR REPLACING BUMP KNOB
See Figures 16 - 17.
 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.
 Remove the bump feed trimmer head housing by rotating
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.
 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 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 and Blade Replacement
ATTACHING THE STORAGE HANGER
See Figure 18.
There are two ways to hang the attachment for storage.
 To use the hanger cap, push in the button and place the
hanger 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.
