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.
WARNING:
When servicing, use only identical 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

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 de-
stroy plastic which could result in serious personal injury.

MAINTENANCE

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 SPEED WINDER
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
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
described.
