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. Failure to do so could result in
objects being thrown into your eyes, resulting in possible
serious injury.
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 edger serviced by an authorized
service dealer.
REPLACING THE BLADE

Stop the engine and remove the spark plug wire.
 Using a 5/16 in. hex wrench to hold blade shaft, use a
24 mm socket wrench to turn the blade nut counter-
clockwise and remove.
 Remove the old blade from the edger shaft.

Clean debris from the edger shaft assembly.

WARNING:
Always make sure the blade is correctly installed and
securely fastened before each use. Failure to securely at-
tach and tighten blade nut may result in serious injury.
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 recom-
mend that only qualified service technicians perform this
service.
SPARK ARRESTOR
The spark arrestor must be replaced every 50 hours or yearly
to ensure proper performance of your product. Spark arres-
tors 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 14.
If the blade 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 blade movement. If the
blade still moves at idle speed, contact a service dealer for
adjustment and discontinue use until the repair is made.
WARNING:
The blade should never turn at idle. Turn the idle speed
screw counterclockwise to reduce the idle RPM and stop
the blade, or contact a service dealer for adjustment and
discontinue use until the repair is made. Serious personal
injury may result from the blade turning at idle.
CLEANING AIR FILTER
See Figure 15.
A dirty air filter will cause starting difficulty, loss of perfor-
mance, and shorten the life span of the engine. Check the
air filter monthly. For best performance, replace the air filter
at least once a year.


Loosen the air filter cover by turning the knob
counterclockwise.
