MAINTENANCE AND REPAIR INSTRUCTIONS

LT31CS LINE INSTALLATION: BUMP HEAD

This section covers both SplitLine™ and standard single line installation.

Always use original equipment manufacturer 2.41 mm (0.095 in) replacement line. Line other than the specified may make the engine overheat or fail.

WARNING: Never use metal- reinforced line, wire,

chain or rope. These can break off and become dangerous projectiles.

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 clockwise (Fig. 51). Inspect the bolt inside the bump knob to make sure it moves freely. Replace the bump knob if damaged.

2.Remove the inner reel from the outer spool (Fig. 51).

3.Remove spring from the inner reel (Fig. 51).

NOTE: SplitLine™ can only be used with the inner reel with the slotted holes. Single line can be used on either type of inner reel. Use Figure 54 to identify the inner reel you have.

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.

6.Take approximately 5 m (16 feet) of new 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. 55). Pull the line through the inner reel so that the loop is as small as possible.

7.Wind the lines in tight even layers, onto the reel (Fig. 56). Wind the line in the direction indicated on the inner reel. Place your index finger between the two lines to stop the lines from overlapping. Do not overlap the ends of the line. Proceed to step 11.
