• Pressure Adjustment

mOdEL "ACC" (fIGURE 7A)
The "ACC" is equipped with suspension angles that support the pressure rollers and hold the drive V-Belt in contact with the tread rollers. Knurled nuts allow
the conveyor to be finely adjusted for minimum pressure accumulation. To make this adjustment, follow the steps listed below.
1. With conveyor running, reduce pressure on all tread rollers to zero by loosening the knurled adjustment nuts.
2. Place heaviest item to be conveyed on infeed end of conveyor. Increase pressure under the item by tightening the knurled nuts. Apply only enough pres-
sure to slightly move the item.
3. As the item moves, continue adjustment ahead of item until it moves the entire length of conveyor.
4. Return item to infeed end of unit. It should now travel the entire length of conveyor. If not, repeat the adjustment procedure in the problem area.
mOdEL "LRC" , "LRS" , "LRSS" (fIGURE 7B)
Curves and spurs have snub sheaves that hold the drive V-Belt in contact with its tread rollers. Adjustments are made by moving the snub sheaves up or
down in the slotted conveyor channel.
When making adjustments, apply only enough force to move the heaviest item to be conveyed.

Snubbing the belt too much can cause the conveyor to stall.

OPERATION

• Conveyor Start-Up

Before conveyor is turned on, check for foreign objects that may have been left inside conveyor during installation. These objects could cause serious damage
during start-up. After conveyor has been turned on and is operating, check motors, reducers, and moving parts to make sure they are working freely.
Because of the many moving parts on the conveyor, all personnel in the area of the conveyor need to be warned that the conveyor is about to be started.
