REPLACING THE LINE BLADES (AERO-FLEX
Only use the line blades described in the Specifications section.
Other types of trimming line may cause the unit to overheat or fail.
WARNING:
Never use metal-reinforced line, wire, chain or
rope. These can break off and become dangerous projectiles.
NOTE: The cutting head base will remain attached to the unit.
1. Disconnect the cutting head cap from the cutting head base:
Firmly press a tab on the cutting head cap (Fig. 29). Use your
thumb. If necessary, use a flat-head screwdriver:
a. Insert a flat-head screwdriver into the notch on the tab (Fig. 30).
b. Gently tilt the screwdriver up and hold it in place (Fig. 30).
c. While holding the screwdriver in place, gently twist the
screwdriver to unlock the tab from the tab slot (Fig. 29).
2. Remove the cutting head cap from the cutting head base. DO
NOT disassemble or remove any other parts on the cutting head
base.
3. Remove the old line blades from the cutting head cap.
4. Use a clean cloth to clean the inside of the cutting head base
and cutting head cap.
5. Hold one of the line blades so that the loop faces to the left.
Align the loop with one of the posts on the cutting head cap (Fig.
31). Push the loop onto the post securely.
6. Repeat step 5 until all four line blades are installed (two yellow
and two orange). Always alternate between yellow and orange
line blades (Fig. 32). Do not install two line blades of the same
color next to each other.
WARNING:
Never install less than four line blades. Doing
so could make the unit unstable and hard to control, which
could result in serious personal injury.
7. Align the tabs on the cutting head cap with the tab slots on the
cutting head base (Fig. 29). Push the cutting head cap onto the
cutting head base until both tabs snap into place.
