Service and Maintenance
Check the condition of the drive belt annually or after 30
hours of operation, whichever comes first. If the belts are
cracked, frayed, or worn, replace them by following the steps
below.
1. Shut off the engine. Disconnect the spark plug wire.
2. Remove the front cover weldment (requires loosening
and removing three bolts).
3. Loosen the four bolts 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 handle support channel (back cover with
tabs to adjust the handlebar). Requires loosening
and removing four bolts.
5. Remove worn or broken belt. If the belt is badly worn
and will not be used again, cut for ease of removal.
6. Install new belt from the front to the back. Feed belt
above the front trimmer pulley and below the rear
pulley.
7. Move the spindle hub by inserting a screwdriver in the
slot on the rear side of the spindle hub and applying
70 lbs. pressure forward until belt is tight. Tighten
bolts.
8. Replace front cover and secure with bolts.
9. Replace the handle support channel (back cover with
handlebar adjustment tabs). The bolts should be
secured with the bolt head beneath and the nuts and
washer above the trimmer body.
