Ryobi RY13050 Manuel D’Utilisation

10 — English

When servicing, use only identical replacement parts. 
Use of any other parts may create a hazard or cause 
product damage.

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.

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.

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.

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.

See Figure 13.
Replace blade when worn down to indicator hole on blade 

or worn unevenly.

Wear gloves during blade replacement. Blade is sharp 
and may cut you.

 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.



  Slide new blade onto edger shaft.



  Install the blade nut onto the edger shaft.



  Using a 5/16 in. hex wrench to hold blade shaft, thread 

blade nut, clockwise, on blade shaft with 24 mm socket 

wrench. Tighten securely.

  This replacement part is  available from the place of 

purchase, or by calling 1-800-860-4050.

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.

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.

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.

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.

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.

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.
