LINE REPLACEMENT
See Figures 17 - 19.
 Stop the engine and disconnect the spark plug wire.
 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 20 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.
IDLE SPEED ADJUSTMENT
See Figure 20.
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.
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 21 - 22.
For proper performance and long life, keep air filter screen
clean.
 Remove the air filter cover. To remove, push up on the
latch at the bottom of the cover and gently pull the cover
up.
 Remove the air filter.
MAINTENANCE
 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 lubricant 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 tabs on the housing, then push the
cover down until it latches securely in place.
FUEL CAP, TANK, AND LINES
Check for fuel leaks. A leaking fuel cap, tank, or line is 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.
SPARK PLUG REPLACEMENT
This engine uses an Champion RY4C, Ryobi AC00164A or
equivalent spark plug with .025 in. electrode gap. Use a rec-
ommended or equivalent replacement and replace annually.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
CHANGING ENGINE LUBRICANT
See Figure 23.
Do not change engine lubricant while it is hot. Accidental
contact with hot engine lubricant could result in serious
burns.
For best performance, engine lubricant should be changed
after every 25 hours of operation.
To change the engine lubricant:
 Stop the engine and disconnect the spark plug wire. Allow
the engine to cool completely before proceeding.
 Remove the screw from the top engine cover and set
aside.
