 Rotate the spool clockwise as necessary to align the
arrows on the spool with the eyelets in the string head
housing.
 Cut one piece of trimmer line 14 ft. long. Insert the line
into the eyelet on the string trimmer housing. Push until
the end of the line comes out the other side of the string
head. Pull the line from the other side until equal amounts
of line appear on both sides of the spool.
 Rotate the spool clockwise to wind the line on the spool
until approximately 6 in. of line is showing on each side.
 Push the spool retainer down while pulling on line(s) to
manually advance the line and to check for proper as-
sembly of the string head.
CLEANING THE EXHAUST PORT, MUFFLER,
AND SPARK ARRESTOR
NOTICE:
The spark arrestor on this product has not been evalu-
ated by the USDA Forest Service and cannot be used on
U.S. forest lands. In addition, product users must comply
with Federal, State, and local fire prevention regulations.
Check with appropriate authorities. Contact customer
service to purchase a replacement spark arrestor.
NOTE: Depending on the type of fuel used, the type and
amount of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power
loss with your gas powered tool, you may need to remove
these deposits to restore performance. We highly recom-
mend that only qualified service technicians perform this
service.
The spark arrestor must be cleaned or replaced every 50
hours or yearly to ensure proper performance of your prod-
uct. Spark arrestors may be in different locations depending
on the model purchased. Please contact your nearest service
dealer for the location of the spark arrestor for your model.
IDLE SPEED ADJUSTMENT
See Figure 15.
WARNING:
The cutting head will move when adjusting the idle speed.
Wear all protective clothing and keep all bystanders,
children, and pets at least 50 ft. away. Make adjustments
with the unit supported by hand so that the cutting head
does not contact the ground or any object. Keep all parts
of your body away from the cutting head and muffler.
Failure to follow these instructions could result in serious
personal injury.
MAINTENANCE
If the cutting attachment turns at idle, the idle speed screw
needs adjusting on the engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the cut-
ting attachment movement. If the cutting attachment still
moves at idle speed, contact a service dealer for adjustment
and discontinue use until the repair is made.
WARNING:
The cutting attachment should never turn at idle. Turn
the idle speed screw counterclockwise to reduce the
idle RPM and stop the cutting attachment, or contact a
service dealer for adjustment and discontinue use until
the repair is made. Serious personal injury could result
from the cutting attachment turning at idle.
CLEANING THE AIR FILTER
See Figures 16 - 17.
For proper performance and long life, keep air filter clean.
 Remove the air filter cover by pushing down on the latches
while gently pulling off the cover.
 Remove the air filter.
 Clean the foam filter element with warm soapy water.
Rinse and let dry.
NOTE: If the foam filter element is damaged, it should be
replaced.
 Apply a light coat of engine oil to the foam filter element,
then squeeze it out.
 Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
 Replace the air filter cover by placing the slots on the air
filter cover over the latches on the housing, then push
the cover down until it snaps securely in place.
FUEL CAP, TANK, AND LINES
WARNING:
Check for fuel leaks. A leaking fuel cap, tank, or lines
are a fire hazard and must be replaced immediately. If
you find any leaks, correct the problem before using the
product. Failure to do so could result in a fire that could
cause serious personal injury.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine perfor-
mance. If performance improves when the fuel cap is loos-
ened, check valve may be faulty or filter clogged. Replace
fuel cap if required.
