Ryobi 130rEB manual Maintenance And Repair Instructions, Servicing Of Double Insulated Units

MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: To avoid serious personal injury, be sure the unit is off and unplugged before cleaning or performing any maintenance on it.

SERVICING OF DOUBLE INSULATED UNITS

This unit is double-insulated. In a double-insulated unit, two systems of insulation are provided instead of grounding. No means of grounding are provided on a double-insulated unit, nor should a means for grounding be added to this unit.

Servicing a double-insulated unit requires extreme care and knowledge of the system, and should be done only by qualified service personnel. Replacement parts for a double-insulated unit must be identical to the parts they replace. Refer any repair to an authorized service dealer. A double-insulated unit is marked with the words “DOUBLE INSULATION” or “DOUBLE INSULATED.”

LINE INSTALLATION

Always use genuine Ryobi 0.080 inch (2.03 mm.) replacement line. Line other than specified may make the motor overheat or fail.

WARNING: To prevent serious personal injury, never use metal-reinforced line, wire, or rope, etc.. These can break off and become a dangerous projectile.

There are two methods to replace the trimming line.

•Wind the inner reel with new line

•Install a prewound inner reel

Winding the Existing Inner Reel

1.Hold the outer spool with one hand and unscrew the Bump Knob™ counterclockwise (Fig. 18). Inspect the bolt inside the Bump Knob to make sure it moves freely. Replace the Bump Knob if damaged.

6.Take approximately 25 feet (7.6 m) of new 0.080 inch diameter trimming line, loop it into two equal lengths. Insert each end of the line through one of the two holes in the inner reel (Fig. 22). Pull the line through the inner reel so that the loop is as small as possible.

NOTE: Always use the correct line length when installing

trimming line on the unit. The line may not release properly if the line is too long.
