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 AIR FILTER
See Figure 18.
Clean the air filter as indicated by the maintenance schedule.
To clean the air filter:
 Loosen the air filter cover by turning the knob counter-
clockwise.
 Remove the air filter cover.
 Remove the air filter.
 Lightly tap or blow out dirt particles from filter.
 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.
 Reinstall the cover.
 Tighten knob to secure.
NOTE: For best performance, the air filter should be re-
placed once each year.
FUEL CAP, TANK, AND LINES
WARNING:
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
See Figure 19.
This engine uses a Champion RY4C, Ryobi AC00164A or
equivalent spark plug with 0.025 in. electrode gap. Use a rec-
ommended or equivalent replacement and replace annually.
 Remove the screw on back of the engine housing. This
will allow the engine housing to uncover as shown.
 Remove the spark plug wire.
 Loosen the spark plug by turning it counterclockwise with
a socket wrench.
MAINTENANCE
 Remove the spark plug.
 Hand thread the new spark plug, turning it clockwise.
 Tighten with a socket wrench and torque to 170 in. lb.
minimum, 190 in. lb. maximum. Do not overtighten.
 Secure the engine housing back into place and return the
screw. Ensure that the housing is stable.
NOTICE:
Be careful not to cross thread the spark plug. Cross
threading will seriously damage the product.
CHANGING ENGINE LUBRICANT
See Figure 20.
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 oil fill cap/dipstick.
 Tip the unit backward so the handles rest on the ground
and allow lubricant to drain from the oil fill hole into an
approved container.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
 Return the unit to an upright position and refill with lubri-
cant following the instructions in the Adding/Checking
Engine Lubricant section previously in this manual.
NOTE: Used lubricant should be disposed of at an approved
disposal site. See your local retailer for more information.
ADJUSTING CAMSHAFT-TO-ROCKER ARM
CLEARANCE
See Figures 21 - 23.
Inspect the camshaft-to-rocker arm clearance after every
25 hours of operation. This should be done in a clean, dust-
free environment.
NOTE: This procedure requires partial disassembly of the
engine. If you are unsure if you are qualified to perform this
operation, take the unit to a qualified service center.
 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. Remove
engine cover and set aside.
 Using a Torx screwdriver, remove the screw from the
rocker arm cover. Remove the cover and set aside.
