Treadwall

®

 maintenance is easy and requires only lubrication and attention to a number of

adjustments relating to the alignment of the wall.  The most important maintenance of the
Treadwall occurs during the first month of operation when the chains and cables are stretching to
their final length. 

It is very important to keep the angle-adjuster cables tight during this break-in

period so that the winds remain even and do not overlap. Also the drive chain and panel chains
must be tightened after 2-3 weeks of use. Instructions for these adjustments are found inside of
the control panel cover.

  MAINTENANCE PRIORITY ITEMS 

1. First month

A. Adjust the drive chain and main chains

See the inside of the control panel door for easy instructions.

People required: 1
Time required: 10 min.
Tools required: Adjustable wrench
   

B.  Re-tighten Adjuster Cables

 on each side 

at least every week or when loose 

for the

first month

.  

This is very important for the proper functioning of the angle adjustment as

the cables tend to stretch during the break-in period.  

If they become loose, the cables can become tangled and break.  They
should be kept firm, with no slack.    
Use the turnbuckles at the back end; loosen their lock nuts, and tighten in a
correct manner, then re-tighten lock nuts.  
A small screwdriver is useful for tightening the turnbuckles. 
Swing wall back and forth to check after tightening.  Cable turns should stay
together.  Tapping cable helps to equalize both sides.
