Spring tension is based on the number of blades on the
cleaner, not the belt width. Shading indicates preferred
spring option.

13S. Set the correct blade tension.
Refer to the
chart or the decal on the mounting base
for the spring length required for the belt
width. Lightly pull the pivot rod toward
the end of the torque arm slot nearest the
pole and turn the adjusting nuts until
the required spring length is achieved
(Fig.13S). Complete steps 12S and 13S on
the other side. For best results, recheck
the spring length on the first side to insure
there has been no movement.
14S. Test run the cleaner.
Run the conveyor for at least 15 minutes and
inspect cleaning performance. Check the spring lengths for proper
tensioning. Make adjustments as necessary.
NOTE:
Tensioners are shipped with the air bags and torque arms attached to the
mounting bases.
9P. Tension the blades to the belt.
Collapse both air bags (with C-clamps) and rotate
the blades until they are 25mm short of contact with the belt. Tighten the torque
arm locking bolts and jam nuts (Fig. 9P).
10P. Connect the supply lines and set tension pressure.
With the parts supplied, attach a line to each air
bag and run the lines to the outlet side of the PAT
control box (Fig. 10P).
NOTE:
Be sure lines are
safely away from the belt. Connect a line from the
inlet side of the box to the site’s supply or air tank.
Test the connections for leaks and set the pressure
per the chart on the control box (also shown below).
Take the pressure chart label from the instruction
packet and affix it in an easily accessible location
near the regulator for future reference.
11P. Test run the cleaner.
Run the conveyor for at least 15 minutes and inspect cleaning
performance. Make adjustments as necessary.
