OPERATING INSTRUCTIONS  
OPERATING THE TRIMMER  
DECORATIVE TRIMMING  
Decorative trimming is accomplished by removing  
all vegetation around trees, posts, fences, etc. Use a  
30-degree angle when trimming with this method  
(Fig. 10).  
WARNING: To avoid serious personal injury,  
wear goggles or safety glasses at all times  
when operating this unit. Wear a face mask  
or dust mask in dusty locations.  
Clear the area to be cut before each use. Remove all  
objects such as rocks, broken glass, nails, wire, or string  
which can be thrown or become entangled in the cutting  
attachment. Clear the area of children, bystanders, and  
pets. At a minimum, keep all children, bystanders and  
pets outside a 50 feet (15m) radius; there still may be a  
risk to bystanders from thrown objects. Bystanders  
should be encouraged to wear eye protection. If you are  
approached, stop the motor and cutting attachment  
immediately.  
NOTE: Remove protective tape from the line cut-off  
blade before operating trimmer.  
ADJUSTING TRIMMING LINE LENGTH  
The bump head allows the operator to release more  
trimming line without stopping the motor. As line  
becomes frayed or worn, additional line can be released  
by lightly tapping the trimming head on the ground while  
operating the trimmer (Fig. 9).  
Fig. 10  
TIPS FOR BEST TRIMMING RESULTS  
The correct angle for the cutting attachment is  
parallel to the ground.  
NOTE: Do not rest the bump head on the ground.  
DO NOT FORCE THE UNIT. Allow the very tip of the  
line to do the cutting (especially along walls). Cutting  
with more than the tip will reduce cutting efficiency  
and may overload the motor.  
Grass over 8 inches (200 mm) should be cut by  
working from top to the bottom in small increments  
to avoid premature line wear or motor drag.  
Bump Head  
Whenever possible, cut right to left. When cutting to  
the left, the unit's cutting efficiency is improved  
slightly. Also, the clippings are thrown away from the  
operator.  
Slowly move the trimmer into and out of the area  
being cut, maintaining the trimmer at the desired  
cutting height. This can be either a forward-  
backward or side-to-side motion. Cutting shorter  
lengths produces best results.  
Fig. 9  
NOTE: Always keep the trimming line fully extended.  
Line release becomes more difficult as cutting  
line becomes shorter.  
Trim only when grass and weeds are dry.  
The life of your cutting line is dependent upon  
following the previous trimming techniques, what is  
being cut, and where the cutting is being done. For  
example, the line will wear faster when trimming  
against a foundation wall as opposed to trimming  
around a tree. Some line breakage will occur from:  
WARNING: Do not remove or alter the line  
cutting blade assembly. Excessive line length  
will cause the motor to overheat and may  
result in serious personal injury.  
Each time the head is bumped, approximately 1 inch  
(25.4 mm) of trimming line is released. A blade in the  
string guard will cut the line if excess line is released.  
For best results, tap the head on bare ground or hard  
soil. If line release is attempted in tall grass, the motor  
may overheat. Always keep the trimming line fully  
extended. Line release becomes more difficult as the  
cutting line becomes shorter.  
Entanglement with foreign matter.  
Normal line fatigue.

fenceposts

MAINTENANCE AND REPAIR INSTRUCTIONS  
REPLACING THE CHARGER  
Replace the charger if it is damaged, or if the barrel  
connector or cord become damaged, or if the barrel  
connector is not connecting to the unit properly.  
CLEANING THE UNIT  
WARNING: Battery tools do not have to be  
plugged into an electrical outlet; therefore,  
they are always in operating condition. To  
prevent serious personal injury, take extra  
precautions and care when performing  
maintenance, cleaning or servicing the unit.  
CAUTION: Only use the type of charger  
specified for this unit. Any other type may  
cause damage to the unit, batteries and  
possible injury.  
WARNING: To prevent serious personal  
injury, remove or disconnect the battery  
before servicing, cleaning, changing add-on  
attachments or removing material from the unit.  
Your trimmer requires a Ryobi #182534 12V charger and  
#180295 charging station. The charging instructions  
refer only to these parts.  
NOTE: If you are using the optional Battery and Charger  
Accessory Kit to charge your battery. Read and  
follow all instructions in the manual that comes  
with the kit to set up and properly charge your  
battery.  
Clean the unit using a damp cloth with a mild  
detergent.  
Do not use any strong detergents on the plastic  
housing or the handle. They can be damaged by  
certain aromatic oils such as pine and lemon, and by  
solvents such as kerosene. Moisture can also cause a  
shock hazard. Wipe off any moisture with a soft dry  
cloth.  
1. Unplug the charger from the wall outlet and remove  
the unit from the charging station.  
2. Remove the screw from the clamp holding the barrel  
connector in place using a standard or T-20 Torx bit  
screwdriver (Fig. 19).  
Use a small brush or the air discharge of a small  
vacuum cleaner brush to clean the air vents on the  
battery housing and motor housing.  
3. Remove the barrel connector from the slot and  
replace charger, if needed.  
Keep the air vents free of obstructions  
4. Insert the narrow side of the barrel connector wire  
into the groove in the slot of the charging station.  
Ensure the barrel connector is inserted correctly and  
secure (Fig. 19).  
STORING THE UNIT  
Clean the unit thoroughly before storing it. Hang  
the unit on the charging station. Store the unit in a dry,  
well-ventilated area, locked-up or up high, out of the  
reach of children.  
To maintain the life of the battery, only store the unit in a  
place where temperatures do not exceed 100°F or drop  
below 40°F.  
5. Reinstall the clamp and screw.  
6. Plug the charger into the wall outlet. Refer to  
Charging the Unit for charging instructions.
