D. Conveyor Installation

1. Unfold the conveyor frame so that it lies flat on the floor. As

you unfold the frame, check that the locator pins shown in

Figure 2-8 lock into the slots on the bracket.

2. Refer to Figure 2-8. Note the locations of the four tensioning

screws (2 per side) in the slotted holes on the brackets.

Loosen these screws to allow the conveyor to be properly

tensioned.

3. Lift the conveyor belt away from the frame, as shown in

Figure 2-8, to check the belt tension. The belt should lift

between 1-2" (25-50mm).

If it is necessary to adjust the belt tension, gently push the

two conveyor frame sections closer together, or further

apart, as required. Then, re-check the tension of the

conveyor belt. Repeat this step as necessary until the

proper belt tension is achieved.

4. When the belt tension is correctly adjusted, tighten the two

tensioning screws on each side of the conveyor frame.

This fastens the two frame sections together at the correct

belt tension.

5. If it is necessary to add or remove conveyor links to achieve

the correct tension, OR if it is necessary to reverse the

conveyor belt for correct orientation, the belt will need to be

removed from the conveyor frame. If this is necessary,

perform the following procedure:

a. Remove the master links using long-nose pliers.

Then, roll up the belt along the length of the conveyor

frame.

b. Add or remove belt links as necessary to achieve the

correct belt tension.

c. Replace the belt on the conveyor frame. Check the

following:

 The conveyor belt links must be oriented as shown

in Figure 2-9.

 The smooth side of the conveyor belt must face

UP.

d. Connect the inside master links. Check that the links

are oriented as shown in Figure 2-9.

e. Connect the outside master links. Note that the

outside master links each have an open hook on one

side. This hook aligns with the hooks along the sides

of the other conveyor links. See Figure 2-9.
