CLEANING THE EXHAUST PORT AND
MUFFLER
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 recommend
that only qualified service technicians perform this service.
SPARK ARRESTOR
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 22.
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 may result
from the cutting attachment turning at idle.
CLEANING AIR FILTER SCREEN
See Figures 23 - 24.
For proper performance and long life, keep air filter screen
clean.
Remove the air filter cover by pushing down on the latch
with your thumb while gently pulling on the cover.
Brush the air filter screen lightly to clean.
Replace the air filter cover by inserting the tabs on the
bottom of the cover into the slots on the air filter base;
push the cover up until it latches securely in place.
FUEL CAP
WARNING:
Check for fuel leaks. A leaking fuel cap 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 a Champion RCJ-6Y, NGK BPMR7A, or
Ryobi AC00160 spark plug with .025 in. electrode gap. Use
an exact replacement and replace annually.
