TREADWALL MAINTENANCE
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. This card is re-printed below:
THE CRUCIAL FIRST MONTH:
Following these instructions for adjustment
during the break-in period is very important to
the health of your Treadwall. These simple
adjustments assure that stretching chains and
cables will not result in damage to the
machine. After the first month, maintenance
requirements are very low.
After the initial break-in period, follow the
schedule below.

TREADWALL MAINTENANCE
Drive Chain Adjustment:
The drive chain connects the pump in this panel to the top shaft. Over time, the
chain will stretch and need adjustment.
•Use the long push-down bolt (A) to push down the pump and panel. This
will tighten the chain. As you adjust the chain you can feel the amount of
slack through the round access hole (B). Adjust slowly and just take out the
excess slack. Do not over-tighten or the Treadwall will operate sluggishly.
•If you over-tighten the chain by mistake, loosen the push-down bolt (A) and
pry the chain through the access hole (B) with a large screwdriver or wrench
to loosen it up.
Cable Turnbuckles:
The cables that adjust the angle of the wall must be kept tight. If they become
loose, fraying and breakage will result.
•Check and tighten the turnbuckles (C) often during the first two weeks of
operation as the cables stretch to their final length. Make the turnbuckles as
tight as you can by hand. Do not over-tighten with a tool. Check monthly and
tighten as necessary.
Interior Turnbuckles:
The turnbuckles inside the wall (D) keep it from swaying from side to side. They
should be wired closed and should not loosen up in normal use.
•If they become loose, make them finger tight (no more) and wire them
closed.
Main Chains:
•The wall panels hang from heavy-duty chains inside of the wall.
•These chains should be sprayed with chain lube every six months. Spray
through the access holes as an assistant moves the wall around.
•The main chains occasionally need
re-adjusting as they stretch. If the
wall hangs up, check at "point x". If
the main chains are loose, the
panels will jam trying to enter the
channel at this point.
•To tighten the chains, loosen the
bearing mounting bolts slightly and
use the chain tension adjusters (E)
to push down the adjustable
bearings at the bottom of the
channels. Just a turn or two should
be enough to take out the slack. If
you tighten them too much, the wall
will operate sluggishly. When the
chains are adjusted properly, the
panels should clear the flange at
'point x' with about 1/2" of
clearance.

CLEANING HOLDS.
Clean holds make a big difference in the
climbing experience. As the Treadwall is
used, the climbing holds get contaminated
with dirt and grime and eventually become
slick and greasy to the touch and unpleasant
to climb on.
When you look at dirty holds, you may think
that they need replacing, but really all they
need is a good cleaning. If you take them off
and run them through a dishwasher for a
couple of cycles or just scrub them off in a
sink with a brush and soap, you will be
amazed at how much better they look and
feel.
You don’t need to clean them all at once. If
you just take off the 10 dirtiest holds every
month or so and give them a good washing,
you can rotate them around and keep them in
good shape.
TOUCH-UP PAINT:
Treadwall panels are painted with a high-
quality enamel paint that is very dark gray. A
mixture of 50% battleship gray and 50% black
will give a good match for touch-up purposes.
The white frame color can be matched with
automotive touch up paint: Toyota #3226.

Treadwall® Service Sheet #1:
Panel removal
The Treadwall wall panels are bolted to a set of chains. These two
chains form a continuous loop around the top and bottom axles.
Each panel is attached by two bolts at the ends to flanges mounted
on the chains.
Tools needed:
Phillips screwdriver or VSR drill with phillips bit,
3/8" box end or open end wrench, needle nosed pliers.
Panel hardware:
10-32 x 1 1/4" truss head screws, phillips-drive
10-32 nylon locknuts.
Removing a panel is simple and requires about 15 minutes effort.
Rotate wall so that desired panel is in front of the rectangular
opening. Remove four panel bolts and their locknuts by using the
opening to access the back. Rotate the wall downward and allow
the panel to drop out at bottom. Multiple panels can be removed in
a similar manner if necessary. Rotate the wall until the opening is
at the height where service is required.
Replace panels by inserting panel at bottom and rotating upward
until it is in front of rectangular opening. Be careful not to pinch
fingers. Replace all four bolts. Bolts should be snug but not overly
tight.
Note that the hold-mounting holes are off-center and are intended
to be staggered from panel-to-panel.

Treadwall®Service Sheet #2:
FRAME ADJUSTMENT WITH "X-BRACING"
Adjustment of the Treadwall frame by means of the "X-Bracing" in
the back allows the wall to be centered between the main side
frames. It is important both for angle adjustment as well as the
wall's performance that the wall be centered.
With the wall at vertical, note the gaps between the side channels
and the two main side frames. When the wall is centered, the gap
on the right side (just below the angle-adjuster wheel) should be
3½”
If the wall needs adjustment, loosen both turnbuckles at the bottom
of the "X-Braces" in the back; re-tighten on the side to which you
wish swing the wall. For example, if the wall is too close to the left
side, you will need to tighten the right "X-bracing" to bring the wall
closer to the right side.
You may find as you tighten one side, you will have to continue to
loosen the opposite turnbuckle to give yourself enough slack.
When the adjustment is complete, tighten down the locknuts to
secure the turnbuckles.
Special adjustment for left-mounted wheel: Note that there is
normally a smaller gap at the left side than at the right. Sometimes
Treadwalls must be installed with the adjustment wheel on the left
side of the machine. In this case, the turnbuckles should be
adjusted so that there is extra space at the left side for the angle
adjuster to work correctly. With this adjustment the channels will
not be completely parallel to the A-frames, but this will not affect
the performance of the Treadwall.

Treadwall® Service Sheet #4a:
REPLACING CABLES
Tools needed:
1. Ball peen hammer
2. A small box wrench with closed end. (Exact size not
important.)
Procedure (Same on both sides):
Removing...
1. Lock wall in a position so hole in Adjuster Pipe faces up (Note
how cable dips into hole near the center of the windings and is
locked in place with a bolt inside pipe.)
2. Lift side cover.
3. Remove chrome Adjuster wheel (right side) or plastic cap (left
side) from the end of Adjuster Pipe. The wheel simply
unscrews from the pipe. To remove it, engage the locking disk
to the channel and turn the wheel hard to the left. Remove the
ball from the locking rod and slip the wheel off.
4. Loosen and disassemble turnbuckle. slip the end of the cable
through the guide loop.
5. Remove Cable Guard.
6. Using the closed end of a wrench, reach into Adjuster Pipe
end and pull out bolt that holds cable to pipe.
7. Remove pin from front frame, and cable will come free.
Installing...
1. New cable is pre-bent at a certain spot. Note that the bend is
not exactly in the middle, so that one end is slightly shorter
than the other. Push the bend into Adjuster Pipe hole so that
the shorter end leads to back of machine. (After winding, the
cable will leave pipe at bottom as in fig. 1 and the shorter end
will go towards front of machine)
2. Re-insert bolt to catch the loop of cable inside pipe.
3. Pull up on cable to take-up all cable slack around the bolt that
is inside pipe.
4. Hammer down cable on both sides where it exits the hole. This
is just to put a bend in cable so it will exit hole and lay nicely
around pipe.
5. Wrap the short end around pipe so as to follow a left hand
thread as shown in fig. 1.

6. After four turns, attach the cable to the front of the frame with
the clevis pin and cotter pin.
7. Wrap the other end and lead up through corner loop at back of
unit. The number of wraps will be clear from the length of the
cable: the turnbuckle will only reach when the correct number
of turns is on the pipe.
8. Hook turnbuckle and tighten. Make sure wraps of cable on
pipe are evenly wound and tight together as you tighten
turnbuckle.
9. Re-install chrome Adjuster wheel and swing wall front and
back to stretch the new cable. Re-tighten turnbuckle.
10. Swing wall front and back to make sure all is working and look
for windings that are spread apart.
11. Once more, tighten turnbuckles to remove any slack. See the
box to the right for a good way to stretch the cables. This
method will remove 90% of the slack.
12. Before stretching the cables, it is a good idea to spray them
with silicone spray. They will stretch easier and last much
longer if you do.
13. When cable is stretched, it is time to install the cable guard.
Slip the cable guard over the windings so that one hook is
engaged with the front end of the cable. Loosen the
turnbuckle a few turns. Now hold the windings at the bottom of
the pipe to keep them from loosening, and with your other
hand remove the turnbuckle from its loop. Continue to hold
the windings in place while you work the rear end of the cable
under the other hook on the cable guard. Re-attach the
turnbuckle and tighten it. This process is easier than it sounds
as long as you don't let go of the windings. You might want to
have someone help with the turnbuckle.
14. Make sure cable wrappings inside the guard are still tight
together when you are finished - this may involve using the
hammer and wrench to tap the windings back together after
you have begun to re-tighten turnbuckle.
15. Tighten the turnbuckles as tight as you can make them by
hand (don’t use a tool to tighten the turnbuckles). Tighten
locking nuts on turnbuckles.
*****PLEASE re-tighten cables each day for the first 4 days to
ensure proper working.*****
Carefully note direction of
wind – same both ends.
TAKING OUT STRETCH
The cables will stretch after
installation, and if they are not
kept tight with the turnbuckles the
coils can overlap and the cable
will shred and break.
Here is a good way to stretch the
cables after installation:
1. Adjust the angle of the wall to
the extreme forward position.
2. Strike downward on the
exposed cables with a piece
of 2x4, a mallet, or even a
hammer. Give them a good
couple of whacks – it won’t
hurt the cables but it will
stretch them.
3. Re tighten the turnbuckles and
re-angle the wall the the other
extreme.
4. Repeat step 2.
5. Do this whole process a
couple of times. When you are
finished, put the wall to
vertical and tighten the
turnbuckles as tight as you
can make them by hand (don’t
use a tool to tighten the
turnbuckles).

Treadwall® Service Sheet #10
Adjustment of chain tension
MAIN CHAINS
The main chains that suspend the panels on the Treadwall will
stretch in the course of the first few months of use. If they are not
adjusted, the panels will be loose as they move around the bottom
and up the back, and they will jam as they attempt to enter the
channel in the back (see diagram). Symptom: Machine jams up
and will not go forward. Reversing the wall slightly frees it but it
jams up again.
The chain tension is adjusted by moving down the bearing on the
bottom of each channel. There is a push-down bolt (E) above each
bearing that will move it down (see diagram).
It is usually not necessary to loosen the mounting bolts on the
bearings to use the tension adjuster, but if they are excessively
tight, loosen them slightly.
Turn the push-down bolt with a wrench to adjust the bearing down.
Do not overtighten the chains. You just want to take out the
excessive slack.
As you tighten the chain, watch point x where the panel is re-
entering the channel at the back of the Treadwall. The panel
should pass the end of the flange at point x with a clearance of
about ½”
Usually a turn or two of the push-down bolt is plenty. Adjust both
sides.
DRIVE CHAIN
There is a smaller drive chain that connects between the control
pump and the main shaft at the top of the machine.
This chain is adjusted with a similar push-down bolt at the top of
the control panel (A). You can feel the slack in the drive chain
through the access hole (B) above the control panel. Do not
overtighten this chain – just take out the excess slack and leave a
little looseness in it.
If you make it too tight by mistake, you can loosen it by slacking off
the push-down bolt and prying the chain with a large wrench or
screwdriver through the access hole.

Treadwall® Service Sheet #18
Hold placement
It is very important when placing holds on the Treadwall that the
holds do not overlap the space between two panels. A hold that
overlaps two panels will restrict the machine from rotating as the
panel moves around the bottom or top of the Treadwall. In an
extreme case, the force can cause a hold or panel to break.
The holds provided with the Treadwall are designed so that
overlap is not possible, but sometimes users put other holds on
that are larger and have the potential to overlap.
If the Treadwall suddenly locks up and will not rotate, check the
bottom and top of the wall, front and back, to make sure that a hold
has not rotated and overlapped two panels.
Lockup can also be caused by loose chains. See bulletin #10.

Treadwall® Service Sheet #20
Correction of stiff operation
In a properly working Treadwall, a body weight of approximately
60-70 lb.. will operate the wall consistently. If the operation is stiff
or sluggish and will not operate at the minimum weight, there are
several areas that may be responsible.
The two basic reasons for sluggish operation are friction of the
panels in the channels and chains that are too tight.
Symptom Cause Fix
Wall jams tight and won't move
but it will back up and
sometimes move forward
before jamming again.
The panels are catching
on the back of the
channels as they try to
enter the back channel
slot at the bottom -
caused by chains that are
too loose.
The chains that suspend the panels are tightened
at the bottom of the two channels. Loosen the
bearing bolts and use the long bolt to take out the
slack. Do not over-tighten! If the chains are too
tight, it will cause excessive resistance. Just take
out the slack. (see sheet #10)
Wall shows resistance
intermittently at the same place
during each rotation of the
panels.
One or more panels are
binding in the channels. Examine to see if all the panels are loose and free to move.
The ends of the panels
are rubbing against the
channels (especially at
the top) Check at tht top
rear of the machine to
see if there is clearance
between the panel ends
and the channels at each
end of the panels.
Center the panels between the channels: Loosen
the set-screws on both the upper channel
bearings and slide the channels (lever or hammer
and wood block) back and forth to center them.
Re-tighten.
Bottom of channels too
close together. Loosen lower bearing set-screws and spread channels. Reset shaft collars on shaft inside
channels so that they are against the inside of the
bearings.
X-bracing inside channels
too tight. X-braces should
just take up slack and not
be overly tight.
Loosen turnbuckles through access holes. Check
spacing of bottoms of channels , When all
adjustments are correct, re-tighten the turnbuckle
locknuts.
General friction – chains
adjusted correctly and no
rubbing of ends of panels.
Channels need grease Grease channels with spray grease (see sheet
#38)

Treadwall® Service Sheet #28
Moving the Treadwall
The following methods are used in re-locating the Treadwall.
Moving within a room without overhead obstructions.
Casters: Brewer's Ledge provides both light duty (for occasional
moving) and heavy duty (for frequent moving) casters. These
casters are bolted onto the lower cross-member of the side frames
and may be left in place during normal operation. If you need to
move the Treadwall on a regular basis, we recommend these
casters. Call for details.
Moving dollies: 4 wheel moving dollies can be rented from moving
or truck rental companies, and are a convenient way to move the
Treadwall if you have a relatively level, smooth floor. You will also
need an 8 ft. 2x4 and a couple of large c-clamps. Use the 2x4 the
pry up each side of the Treadwall and slip 2 moving dollies under
each bottom frame member (4 total). Then clamp the 2x4 across
the bottom front of the Treadwall to prevent the front legs from
spreading apart while moving it.
Lift and carry: The Treadwall weighs about 1300 lb.. Theoretically
10 people can lift and carry it (especially if they are accustomed to
lifting weights) and it has been done - but not without difficulty. It is
not recommended for any distance more that a couple of feet. If
you go this route, it is absolutely necessary to clamp a 2x4 across
the front of the machine as in the diagram to prevent misaligning
the machine.
MOVING IN A ROOM WITH OVERHEAD OBSTRUCTIONS.
If pipes, ducts, beams or suspended ceilings prevent moving the
Treadwall across the room, removal of the panels is required. This
is a tedious but not difficult job. You will need a socket wrench
with a 3/8" socket, a 1/8" Allen wrench and a bit of patience.
Remove the first 3 panels at the bottom of the machine by
reaching into the gap where the panels go under with the socket
wrench and unscrewing the bolts that hold the panels onto the
chains with the Allen wrench. The rest of the panels can be
removed at waist height by moving the wall around and locking it
into place with the resistance control.
With the panels off, the machine is much lighter and can be tilted
forward by 6 strong people onto a pair of moving dollies. Clamp a
2x4 between the front legs first. At its new location, re-erect the
Treadwall and put the panels back on.
Note that the hold-mounting holes are not symmetrical. As the
panels go back on, they should alternate so that they are
staggered from one panel to the next. If you mark the panels with
post-its before you take them off, you can put them on in the same
order and avoid setting a new route (changing around the climbing

holds) at the end of the move. You can use a cordless drill with a
phillips bit to speed up the job, but don't make the screws too tight
- just draw them up snug. You will probably need a few extra bolts
and nuts, so call us first.
PARTIAL DISASSEMBLY
This option involves taking the panels off and disassembling the
Treadwall down to the major components. The largest part is the
channel assembly which consists of the two side channels
(connected together as they are on the machine) along with the
pulley bar and sprocket shaft at the top, the rear guard and
sprocket shaft at the bottom, and the x-braces. This assembly is
heavy and large, but it will fit diagonally through a normal door and
can be transported with a pickup truck if the top part of the
assembly is rested on the cab.
For equipment, a pair of moving dollies and several moving
blankets are highly recommended. You will also need a good 8'
stepladder.
Remove the panels as described above.
Remove the angle-adjuster cables and the adjuster pipe and wheel
(see service bulletin #4).
Unplug the wires inside the channel and take the upper wires out
of the wire clips. Pull the upper wires out of the channel.
Remove the channel assembly. Take the nuts off the four bearing
bolts that hold the pillow block bearings to the top of the frames
(you have already loosened the right ones). Leave the bolts in
place until the last minute for safety. The channel assembly is
heavy, but four strong people can handle it easily. Place one
person on either side of each channel. After the bolts are removed,
lift the assembly slightly and walk it towards the front of the frame
until it can be rested on the floor. Be careful! it is top-heavy. Lower
it down, turn it on its side, place it on dollies and it it ready to
transport.
Dissasemble the frame. Remove the x-bracing from the bottom
horizontal (you can leave it connected to the top horizontal) and
remove the horizontal bolts so that the frame will come apart.
Reassemble in the reverse order.
TOTAL DISASSEMBLY.
The Treadwall may be totally disassembled into parts that will fit
through a normal doorway. If this is required, an installation kit is
available from Brewer's Ledge that includes a comprehensive
manual and video. Price - $45. Call for details.

Treadwall® Service Sheet #35
Replacing and adjusting the counter switch
he counter switch is a proximity reed switch that is activated by
magnets at the top of the left channel. It can be accessed brom
the back of the machine at the top through the opening between
two panels where they come over the top.
Before replacing a reed switch, make sure the old one is adjusted
properly and check it again. The three magnets should be placed
on the shaft so that the center of the magnets pass under the reed
switch with about a 1/8" gap. The magnets have two flat surfaces.
Make sure that they are oriented so that one flat surface is against
the shaft and the other flat surface faces the reed switch.
The reed switch protrudes slightly from one corner of the bracket.
Note in the diagram which bolt is is mounted on. If you mount it on
the wrong bolt, the switch may not be facing the magnets.
If the original cord is not defective and you have a crimping tool
you can cut the cords and connect the new switch to the old cord
with butt-connectors. To check the old cord, cut and strip the wires
near the old switch and short them out to see if the counter
responds. The counter should register one foot for every two times
you short out the wires.
To replace the switch and cord, it is necessary to remove one
panel (see bulletin #1) so that you can access the cord inside the
wall and clip the new cord into the plastic clips.
Your Reed Switch may be on either the front upper bolt or the rear
upper bolt, depending on the model. All current models have the
switch mounted as on the right, on the rear bolt. This improves
access. Replacement switches will be set up for rear mounting,
and you may simply redirect the existing wires to handle the
change.

and operate with a minimum of weight. This procedure should be
carried out every 6 months.
Time: 10 minutes.
Staff needed:One person.
Tools needed: A can of spray white lithium grease or heavy duty
spray silicone (with red nozzle extender)
The Procedure:
For interior machines, we recommend white lithium spray grease
(available at any auto or hardware store). For exterior machines or
trailer mounted Treadwalls, we recommend heavy duty spray
silicone which is more resistant to accumulation of dirt and
contaminants. Silicone May also be used for interior machines (it is
a little cleaner to use) but it requires more frequent application.
Using your choice of lubricants with the red nozzle attached, start
at the top left front and spray into the gap between the climbing
panel and the channel flange. To Lubricate the inner flange, stick
the nozzle between two panels and apply spray lubricant into the
channel as you move the wall down, coating the inside metal
surface (see diagrams below) where the white nylon buttons slide.
Do the right side next, also making sure to coat both the front and
back surfaces.
Repeat this procedure for the Rear Side of the Treadwall. Move wall down while
spraying rear flange

Photoelectrics.
The photoelectric units on the Model PE Treadwall operate by retro-
reflection. The units send an invisible light beam across the wall to a
reflector. When the beam is broken, the wall locks up. If the wall will not
lock up, or is locked up and will not release unless the transformer is
unplugged from the wall, there may be a problem with the photoelectrics.
Testing:
As each photocell is covered, you should hear a faint click. The
photocells also have pilot lights. Take off the black plastic cap on the
front of the photocell bracket. When you peer into the housing, you can
see the two photocells inside. Each photocell has a red pilot light that
glows when the beam is unbroken. If the pilot lights are facing away from
you, bend a strip of paper to slip in behind the photocell so that you can
see the reflected glow.
If both of the pilot lights are glowing, and they go out when you break the
beam with your hand, the photocells are working correctly. If neither
photocell glows, there probably is a power problem--check the
transformer to make sure it is plugged into a working outlet. There could
also be a misalignment problem if the entire channel has become twisted
so that the photocells are not facing the reflectors properly.
If one of the cells is not glowing, first check to make sure that the mirror
and photocell are clean. If it still does not work, check it with a small
mirror. Hold the mirror about 3-4" from the front of the photocell so that
you reflect the beam directly back into the cell. When you line the mirror
up correctly, the pilot light should glow.
Symptom Possible problem Action
Wall will not lock
up--pilot lights not
glowing
Lack of power to
photocells Check transformer--is it plugged in?
Check connection at bottom of frame where wires plug into
transformer wires.
Check all outside wires to see if they are damaged or broken.
Wall will not lock
up--pilot lights
glowing
Bad connection to
valve coil.
Bad switch in control
panel.
Bad valve-coil or stuck
valve.
Open control panel and check connection to valve coil and switch.
Short out switch in control panel with paperclip- see if wall locks
up when photocells are blocked.
With voltmeter (12 volts) or automotive wiring tester, check voltage
at valve-coil in control panel. When photocells are blocked there
should be 12 volts between the two connections on the valve-coil.
If the voltage is there, and the wall will not lock, there is a bad
valve-coil or the valve itself is stuck open. If you suspect the coil,
remove the mounting nut from the coil and take it off the valve
while the current is flowing. If the coil is good, you will feel fairly
strong magnetic attraction between the coil and valve.

Wall is locked up
and will not release-
It releases when
wall is unplugged or

Dirty photocell or
mirror
Misaligned photocell.
Clean mirrors and photocells.
Usually this is due to misaligned photocells. The photocells send
out an invisible beam across the face of the Treadwall to the
reflectors on the other side. If they are not pointed directly at the
reflectors, the system won’t work right.
Loosen the two long mounting bolts on the lower part of the
photocell bracket and push or pull it into line until it works properly.
Then slip cardboard shims between the photocell bracket and the
channel either in the front or back to keep it in alignment when you
re-tighten the bolts.

If all other causes are eliminated, remove the solenoid-valve from
the manifold and see if the wall rotates. Have a good container
handy to catch the oil. If the valve is stuck, you can usually loosen
it up by blowing it out with compressed air. Replace the oil with
new #30 non-detergent motor oil (the oil level should be about 1"
down from the top of the reservoir after the wall has been in use
for a few minutes.)
Remove the speed-control valve from the manifold. Have a rag
handy to plug up the hole. Hold the rag in the hole and gently
rotate the wall to see if it turns. If this valve is stuck, it can usually
be released by holding it in your hand and tapping it's side with a
small hammer or blowing it out with compressed air. Replace the
oil.

Treadwall Service Sheet #41
Alignment of panels and channels.
Occasionally the channels become misaligned on a Treadwall,
causing the ends panels to rub against the channels. Usually, the
panels have a clearance of ¼” or so at each end, so that when you
look at the top of the machine from the back, you will see a gap
between the ends of the panels and the channels at each side. If
the channels shift to one side, the panels will rub against the
channel at one end and cause the Treadwall to operate very
sluggishly.
To re-align the channels, loosen the two setscrews on both
channel bearings (the large square bearings at the top of each
channel – see second illustration) and use a short length of 2x4
and a hammer to move the channels along the shaft until there is
an equal gap between the channels and the ends of the climbing
panels. Because the channels are connected together by the top
shroud and at other places, they must be both shifted as one unit.
Re-tighten the setscrews firmly.
