• Disconnect electrical power to machine whenever maintaining, repairing, or
servicing Conveyor.
• Replace damaged or missing drive shields and safety labels at start of every
season.
• Proper belt alignment and tension are key to long belt life.
• Belts should be kept in alignment between conveyor side, alignment should be an
even distance between belt and conveyor side on each side.
BELT ALIGNMENT PROCEDURE
Belt runs to loose side (narrowest space between belt and side)
Tighten loose side as necessary or loosen other side as necessary.
Belt tension must be great enough to prevent slippage between drive pulley
and belt.
• Keep tires inflated correctly. Between 55 and 60 PSI.
• Tighten loose and replace any missing lug nuts.
• Drive chains should be kept clean and tensioned correctly to prolong chain life.
Ideal chain tension should allow ½” maximum flex when deflected. Over
tightening will cause damage to bearings and sprockets. New roller chain drives
should be inspected after 50 hours of operation. Every 500 hours thereafter.
During inspection look for; drive interference, damaged chain or sprockets, loose
set screws, proper sprocket alignment, chain tension, proper lubrication, foreign
material buildup, and proper guarding. Roller chain is considered worn out when it
reaches three (3) percent elongation. To check for elongation measure from pin to
pin and compare with new chain. When replacing chain or sprockets it is best
replace both at the same time.
• Be sure the electrical system is setup with proper and adequate phase and
voltage.
