Maintenance inspection is owner's responsibility and must be performed at intervals spe-
cified, following:
Normal Service - Every 50 hrs. of operation or 60 days (whichever comes first)
*Severe Service - Every 25 hrs. of operation or 30 days (whichever comes first)
*Operation in a salt water area is considered "Severe Service."
1. Carefully check steering system components for wear. Replace worn parts.

be performed once each year (by your Authorized Dealer) or whenever steering
mount and/or steering head are disassembled, or if steering effort has increased. Lu-
