WARNING:
When servicing, use only identical replacement parts. Use
of any other parts may create a hazard or cause product
damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Head protection may also be required depending on the
type of attachment used and as prescribed in the attach-
ment’s Operator’s Manual. Failure to do so could result in
objects being thrown into your eyes and other possible
serious injuries.
WARNING:
Before inspecting, cleaning, or servicing the machine, shut
off engine, wait for all moving parts to stop, and disconnect
spark plug wire and move it away from spark plug. Failure
to follow these instructions can result in serious personal
injury or property damage.
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, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
You can often make adjustments and repairs described here.
For other repairs, have the power head serviced by an autho-
rized service dealer.
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 become
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 quali-
fied 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 product. 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.
MAINTENANCE
IDLE SPEED ADJUSTMENT
See Figure 9.
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 cutting
attachment movement. If the cutting attachment still moves at
idle speed, contact an authorized 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 attach-
ment turning at idle.
CLEANING AIR FILTER SCREEN
See Figures 10 - 11.
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 performance. If per-
formance improves when the fuel cap is loosened, check valve
may be faulty or filter clogged. Replace fuel cap if required.

This engine uses a Champion RCJ-6Y or NGK BPMR7A spark
plug with .025 in. electrode gap. Use an exact replacement and
replace annually.
