WARNING:
To prevent serious injury, never perform
maintenance or repairs while the unit is running. Always
allow the unit to cool before servicing or repairing the unit.
Disconnect the spark plug wire to prevent the unit from
starting accidentally.
NOTE: Some maintenance procedures may require special tools or
skills. If you are unsure about these procedures, take the unit to
an MTD authorized service dealer.

REPLACING THE LINE BLADES

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. Firmly press both tabs inward and pull the glider away from the
cutting head base (Fig. 10). If necessary, use a flat-head
screwdriver to lever the tabs.
2. Remove the old line blades from the cutting head base.
3. Use a clean cloth to clean the inside of the cutting head base
and glider.
4. Hold one of the line blades so that the loop faces to the right.
Align the loop with one of the posts on the cutting head base
(Fig. 11). Push the loop onto the post securely.
5. Repeat step 4 until all four line blades are installed (two yellow
and two orange). Always alternate between yellow and orange
line blades (Fig. 12). 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.
6. Align the tabs on the glider with the tab slots on the cutting head
base (Fig. 10). Push the glider onto the cutting head base until
both tabs snap into place.
SWAPPING THE CAPS
