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.
Maintenance and Service

People required: 1
Time required: 10 minutes
Tools required: Small screwdriver, small adj. wrench
2. Two Months.
A. Check Chain tension after the second month of use. Although the chains used on the
Treadwall are designed for much harder use than the Treadwall will give them, they will
stretch slightly upon breaking in. This causes the wall to become stuck. Reversing the wall
slightly frees it up, but it will soon stick again. This is caused by the panels jamming as
they try to re-enter the channels near the bottom at the back. Consequently, we
recommend taking the time after the second month to check the tension.
See the Service Bulletin # 20.
People required: 1
Time required: 10 minutes
Tools required: 9/16" wrench
B. Cleaning the holds is usually scheduled every two months. However individual usage
varies, and the amount of dirt build-up on holds has no long-term effect on the holds
themselves. Use a dishwasher to clean the dirt from holds.
If a dishwasher is not sufficient, use a scrub brush to loosen the dirt.
C. Examine the Harness Cord occasionally to check wear on the cord.
Check area of cord under the cord locks attached to the harness. If the
outer sheath is frayed, replace as soon as convenient.
The Harness Cord runs from the Harness to the Upper Pulley bar;
Replacement of the cord does not involve re-threading the cord inside the
Upper Pulley Bar.
See Service Bulletin # 7.
3. Six Months.
A. Check adjustment of Main Channels relative to the ends of the moving
climbing panels.
Look down watch the panel ends as they round the bottom: does either end
touch the channel?
By adjusting the relative tension on x-braces that run diagonally between
the two channels inside the wall, you can shift the channels relative the
moving wall.
Access the turnbuckles through the excess holes on the lower part of each
channel. The turnbuckles should be wired closed. Remove the wire, tighten
turnbuckle on the opposite side of the rubbing panels, and recheck for
clearance at the panel ends.
Ideally both ends should pass with equal clearance. You may have to
adjust both turnbuckles slightly to achieve this. Re-wire turnbuckles closed.
People required: 1
Time required: 15 minutes
Tools required: Small screwdriver, small open end wrench, pliers

B. The Main Chain and Drive Chain should be lubricated every six months.
Access chains through the access holes on the lower part of Main Channels
and the hole above the control panel.
With an assistant moving the wall slowly, direct nozzle of a spray lubricant
towards chain, and lightly coat the chain. Do both sides.
Preferably, do at the end of the day and let sit overnight with old
newspapers below to catch any drips.
We recommend a lubricant such as "Triflow" which is easily obtained at a
bike shop and does not have an adverse odor or appearance.
People required: 2 people
Time required: 20 minutes
Tools required: "Triflow" or equivalent spray lube with small tube to direct
flow.
4. Yearly Maintenance.
A. The bearings at the top and bottom shafts should be greased every year. The
bearing come pe-greased, and depending on the level of usage,. a small amount of
grease should be applied to the four bearing yearly.
Do NOT over-grease: only a small amount will be necessary.
People required: 1 person
Time required: 15 minutes
Tools required: Grease gun with bearing grease.
