MAINTENANCE
Chain Tension
• The Rotor Drive Chain is properly adjusted when it has
a 1/4" - 5/16" deflection across the top of the
sprockets, while the bottom is tight. If adjustment is
needed loosen the Hex Nut and turn the Adjustment
Bolt until the proper deflection is achieved.
• The Idler is specially designed so that if the Idler is
unable to achieve the 1/4"-5/16" chain deflection, the
chain is worn out and needs to be replaced.
• The Small Seedbox back Drive Chain is properly
adjusted when it has 1/8” - 3/16” deflection across the
sprockets.
• If adjustment is needed loosen the Hex Nut on the
Idler and slide the Idler until the proper deflection is
achieved.
