• the feeder is level and true
• the installation has not warped or twisted the frame
• head and tail pulley are square
• plow is contacting under side.
2.
Turn on the feeder and observe its tracking line on the head and tail pulleys.
If the belt is drifting toward one side of the feeder, then adjust the telescoper on
either side of the machine (see below).
3.
Do not adjust belt tracking rollers, they have been factory set.
Telescoper Adjustment
1.
Determine which side of the machine you want to adjust. Compressing the
telescoper on one side will cause the belt to drift toward that side of the machine.
Conversely, extending the telescoper will cause the belt to drift away from that side
of the machine.
2.
Loosen the jam nut.
3.
Turn the adjusting screw in the desired direction. Often times, only a small amount
of adjustment (1 turn or less) will be required.

4.
Observe the results of the adjustment and then readjust, if necessary.
Steps 2 and 3 may need to be repeated to obtain perfect belt tracking.
As you extend or compress the telescoper, you may be changing the belt
Note:
tension. If belt tension has increased (or decreased) considerably while attempting to
track the belt, then compress (or extend) both telescopers and complete the belt
tracking process again. To avoid this problem, extend one telescoper while
compressing the other to obtain proper belt tracking.
5.
Re-tighten the jam nut located on the telescoper to maintain the new telescoper
position after completing the tracking procedure.
6.
If you are having problems tracking the belt, consult your Siemens representative.
Common causes of belt tracking problems are: uneven or improperly distributed
product loading, twisted frame, or product build up on head or tail pulleys.
