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 four bolts (3) and washers (4) attaching
the transmission cover (5) to the transmission
mount bracket (6). Remove cover (5) to expose the
transmission and gain access to the belts.
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.
