WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key on electric start models.

Failure to follow these instructions can result in serious personal injury or property damage.

CHANGING TRIMMER LINES

The trimmer lines will wear with use and eventually require replacement. Also, you may wish to switch between the thinner and thicker gauge lines to handle differ- ent mowing conditions.

Replace the trimmer lines when they wear to the point that trimming and mowing projects take too long and requires too much maneuvering of the machine. A good rule of thumb is to change the lines when they reach half of their original length.

amount of line should project out from each side of the line holder, creating an overall 22" wide cutting swath. The two lines can be offset to increase the cutting swatch up to 25" wide. DO NOT offset the lines so that the overall cutting swath is greater than 25". See Warning statement at right.

IMPORTANT: Whether replacing one or both lines, they must both be .130" or

.155" in diameter.

5.Repeat steps 2 through 4 to replace the second trimmer line.

WARNING

Offsetting the trimmer lines causes the lines to rotate faster than when they project an equal length on each side. This increases the chance of loose materials being dislodged and pro- pelled at high speeds.

Failure of the operator to wear safety goggles and appropriate clothing and to keep bystanders away can result in severe personal injury or property damage.

Use the extra-heavy duty gauge (.155" diameter) line when cutting thick, tough growth. The thinner gauge (.130" diame- ter) line is for use in less demanding con- ditions, and is also recommended for use near trees or ornamental plantings to help prevent girdling (cutting of bark).

To Change Trimmer Lines:

Figure 5-11: Use this single line, easy-loop pat- tern for all but the more difficult cutting conditions.

1.Stop engine, allow all moving parts to stop and then disconnect the spark plug wire and move it away from the spark plug. Remove the ignition key on electric start models. DO NOT tip the machine. DO NOT touch the metal wear cup on the bottom of the spindle head. This surface may be hot.

NOTE: The two line holders on the trim- mer head are permanently secured by a screw and nut. Do not attempt to remove the line holders as it is not nec- essary to remove them in order to change the trimmer lines.

2.The trimmer lines can be changed

when the trimmer head is in contact with the ground. If necessary, you may tip the unit back slightly for a better view. How- ever, do not tip the unit all the way back or motor oil may flow to the exhaust area and the engine may smoke for several seconds when started.

3.Three different line installation pat- terns are available, as shown in Figures 5-11, 5-12 and 5-13.

4.Simply fee the line through the loops of the line holder as shown. An equal

Figure 5-12: If lines tend to loosen (especially in more difficult cutting conditions), add a single reverse loop and then readjust line so that ends are even. This pattern results in a slightly narrower cutting swath.

Figure 5-13: For more diffi- cult cutting conditions, use two of the thicker (.155" diameter) lines in each line holder. Follow the pattern shown in Figure 5-11.
