WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off motor and disconnect from power supply, and
wait for all moving parts to stop. Failure to follow these
instructions can result in serious personal injury or prop-
erty 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.
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 quali-
fied service center for assistance.
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.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based 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 13 - 14.
Use original manufacturer's replacement line for best
performance.
„ Stop the motor, remove the battery pack for cordless
power heads, or disconnect the plug from the power
source 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.
MAINTENANCE
„ Use one piece of pre-cut trimmer line, or cut one piece
of bulk trimmer line 10-16 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 16 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.
CLEARING LINE JAM AND/OR REPLACING
BUMP KNOB
See Figures 15 - 16.
„ Stop the motor, 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.
„ 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 Replacement.
STORING THE ATTACHMENT
„ Store the attachment in a well-ventilated place that is
inaccessible to children.
„ Keep away from corrosive agents such as garden chemi-
cals and deicing salts.
