Replacing Trimmer Line:
G
Use only 0.080 inch (2 mm) diameter flexible, nonmetallic line with this Trimmer. Other line sizes will not function properly
and can cause serious injury. Never use alternative cutting members such as wire or wire-rope, which can break off and
become a dangerous projectile.
WARNING
1. Stop the engine.
Disconnect the Spark Plug before performing maintenance
except for carburetor adjustments.
2. Position the Trimmer on the ground so that the Trimmer
Head Assembly is facing up.
3. Use the spanner wrench provided to loosen and remove
the Bump Knob (see Fig. 18).
4. Remove spool and spool spring from the Trimmer Head
Assembly, and clear any remaining Trimmer line from the
spool.
5. When replacing Trimmer line only use 0.080 in. (2 mm)
diameter line.
6. Cut a length of new Trimmer line 15 ft. (4.6 m) long.
7. Bend the line in the middle to form a loop of two equal
lengths (see Fig. 19).
8. Hook the bend of the loop onto one of the slots in the
center of the spool (see Fig. 20).
9. With your finger between the Trimmer lines of the loop,
wrap the lines – keeping the lines taut with firm, constant
tension - around the spool in a clockwise direction.
Make sure to keep each of the Trimmer lines on the proper
side of the center divider on the spool (see Fig. 21).
10. Confirm spool spring is secured in proper position on
spool (see Fig. 22).
11. While securing the Trimmer line around the spool, insert
spool into the Spool Housing and insert the end of each
of the Trimmer lines into opposing eyelets in the Spool
Housing. Pull the Trimmer line through eyelets removing
any slack in the line. The Trimmer line should extend
through each eyelet approximately 4 inches (102 mm).
12. Hand tighten the Bump Knob onto the Spool by turning
counter-clockwise (see Fig. 23).
13. Insert the Star Drive Key through the slot in the
Flanged Spacer and Gear Head, and put the Trimmer
Head Assembly onto the drive shaft of the Gear Head, and
secure it by turning the Spanner Wrench counter-clockwise
(see Fig. 24).
14. After installing new Trimmer line, start Trimmer engine
and advance Trimmer line with Bump Knob until Trimmer
line is trimmed at its full cutting width by the Trimmer line
knife (see
E. Advancing Trimmer Line
).
