SPARK PLUG WIRE FROM SPARK PLUG AND MAKE SURE ALL MOVING PARTS HAVE COME TO A COMPLETE STOP.
5.5 DRIVE BELT CHECKING, TENSIONING, AND REPLACEMENT
Check the condition of the drive belt annually or after 20
hours of operation, whichever comes first. If the belt is
cracked, frayed, or worn, replace it by following these
steps:
1. Shut off the engine. Disconnect the spark plug wire.
2. Remove the front cover (1).
3. Loosen the four bolts (2) fastening the spindle hub to
the trimmer bottom frame. This will allow the spindle
hub with the attached trimmer pulley to move freely.
4. Remove the two screws (3) on the sides of the body
at the back of the machine. Push up on the back of
the engine and down on the handle bar. The body will
pivot near the front of the engine, opening the back,
and exposing the belt. Place a small block of wood in
the opening to keep from closing.
5. Remove worn or broken belt.
6. Install new belt from the front to the back. Feed belt
above the front trimmer pulley and below the rear
pulley.
WARNING
7. Remove block of wood. Close trimmer body and
8. Move spindle hub forward to apply belt tension.
9. Replace front cover.
