To keep your spreader running smoothly, observe the
following recommendations:
• Lubricate grease fittings after each use and at the
end of each season.
Belt Tension
• Maintain proper motor to shaft belt tension.
To adjust belt tension:
1. Loosen the carriage bolt that holds down the idler.
2. Slide the carriage bolt to increase or decrease
tension.
3. After adjusting the idler, tighten the carriage bolt.
4. After tightening the carriage bolt, the belt should
deflect 5/8” between the pulleys.
MAINTENANCE
Conveyor Belt Tension
To adjust the conveyor belt tension, please adhere to
the following instructions.
1. Loosen the two bearing mounting bolts on each of
the idler bearings.
2. Loosen the locknut on the idler bolt and then tighten
the idler bolt about one full revolution.
3. Repeat this evenly on both sides of the unit.
4. Start the unit to determine if the tension is tight
enough to restart the load. If it is not, repeat the
procedure until the load restarts.
5. Run the load for a few minutes and check the idler
pulley to determine if the belt is running closer to
one side than the other. If belt tracking is centered
and not rubbing the inside of the sills, retighten the
locknuts against the angles and retighten the
bearing mounting bolts.
6. If the belt is tracking off center, tighten the idler bolt
of the side that the belt is tracking towards.
Sometimes it is necessary to over tighten this side
to make the belt track back to the other side and
then loosen the idler bolt slightly to maintain center
tracking of the belt.
7. After it is determined that the belt is tracking
straight, retighten the locknuts against the angles
and retighten the bearing mounting bolts.
