The Mirrix Spencer Power Treadle
Getting Started:
Congratulations on purchasing a Mirrix Spencer Power Treadle. This treadle
will make weaving on your Mirrix Loom faster and easier.
This guide will show you how to install the treadle on your loom, how to use
the treadle and includes some safety warnings and troubleshooting information.
If you have any questions, feel free to contact us
(customerservice@mirrixlooms.com).
Please note that to use this treadle you need a Mirrix Loom with a shedding
device and wooden clips on the loom.
The Parts of The Treadle:
In this guide we will be referring to various parts of your treadle. Following
are labeled pictures of each part.
Black Bushing (installed on motor)

Installing the Spencer Power Treadle
The Mirrix Spencer Power Treadle consists of four connected assemblies: the
motor, the pedal switch, the control box and the power supply. The cotter pin
secures the black bushing on the motor to your loom’s shedding device. Please
note that the treadle needs to be installed on the right side of the loom.
Begin with a warped Mirrix Loom complete with a shedding device and heddles.
Do not place the shedding device handle on the loom, as the treadle will
replace this. Remove the black plastic cap on the right side of the shedding
device. This is where the black bushing connected to the treadle motor will be
placed.
First, hold the motor so that the U-bolt straddles the end of the wooden clip
behind the copper side bar of the loom. One arm should be above the clip and
the other (with the blue plastic bushing) should be below it. Next, you will
slide the shaft with the pressed on bushing into the copper shedding device
bar and secure it with the cotter pin. Make sure that the holes in the motor
shaft, bushing and shedding device are aligned so the cotter pin can pass
through all three.
If they are not, you can use the end of the cotter pin to align them. Please
note that the motorshaft will move fairly easily in the clockwise direction
(when viewed from the motor shaft end) but will not move in the
counterclockwise direction.
Loosen the nuts on the U-bolt to adjust its position so that the lower arm
fits securely in the crotch between the bottom of the clip and the side bar of
the loom. Tighten the nuts gently and test to see that the motor moves the
shedding device smoothly without binding or wobbling around too much (you will
have to plug in the treadle to test this, see below.) Once the best position
is found, tighten the nuts completely.
Finishing the installation
Plug the small power cord from the power supply into the control box. Attach
the AC power cord to the power supply and plug it into a wall socket or power
strip. Each press of the pedal will move the motor in the direction opposite
to the previous move. The motion is stuttered and slow, allowing you to
position the shed any way you like from full shed to neutral shed. The control
box has a purple cord threaded through the cover. This can be used to secure
the control box to the loom or the stand if you are using one. It is best to
not have the control box on the floor. Wherever you place the control box and
the power supply, be sure that the power connector where it is plugged into
the control box is not strained. It should not be supporting the weight of the
power supply via the cord. This could damage the socket as well as the cord.
If necessary, use an extension cord to allow everything to be where you want
it. The shedding device bar should move smoothly without binding.
The motor should not rock excessively. If it does, the U-bolt should be re-
adjusted so it works smoothly without excessive rocking. It is normal for the
motor to have a little more power in one direction. This is the nature of
motors of this type. However, even the lower powered motion should be adequate
for even the highest warp tension if the installation is correctly done.
Using the Treadle
To operate the treadle, depress the pedal one way or the other to move between
sheds. Be sure to release the switch once the desired shed is achieved. Do not
leave your foot on the switch for extended periods of time. If you leave the
switch on in either position it will cause the power supply to go into
protection mode and it will shut off briefly. No damage will be done but it
is best to avoid shutdowns. It is also possible that the motor will warm up a
bit if the switch is left on.
Safety Warnings
The motor in this device is quite powerful. Do not allow fingers (or anything
else you value) to get between moving parts such as the hairpin cotter and the
wooden clip. If you need to make adjustments and there is any chance of your
finger (or anything else you value) getting caught between moving parts,
unplug the power cord while doing these operations or at least make sure you
do not depress the pedal switch.
When not using the power treadle, it is best to unplug it.
This treadle is not intended for use by anyone under the age of 18.
If you have any questions about using alternate power sources, please contact

Troubleshooting:
No motor movement when pedal is depressed:
Is the power cord securely plugged into the power supply? Is there voltage at
the wall or power strip outlet? Plug in a lamp to be sure. Is the power cord
damaged? Try another cord. Are the wires connected securely to the motor?
Check to be sure the connectors are plugged securely to the motor and that the
wire is not loose in the connector. Tug gently on each wire to test. Do not
pull hard but if a wire pulls out easily, the connector will need to be
replaced and properly crimped on.
Clunking noises when changing shed or excessive motor wobbling:
Read the installation section above for proper adjustment procedure. The blue
plastic bushing should fit in to the crotch between the wooden clip and
upright copper tube but should be loose enough to allow a little motion to
prevent binding.
Binding together with only partial motion (does not achieve full shed):
The U-bolt position needs to be adjusted so there is a little space between
the white busing and the wooden clip and upright copper tube.
Greater power moving shed in one direction as opposed to the other:
This is normal to an extent. One direction will be a little more powerful. If
there is not enough power to move to full shed in the weaker direction, there
is most likely some binding and the Ubolt needs to be adjusted.
