Step 2
Pull out the plunger style lock pin on
bottom right hand corner of hoop
frame as you push front of hoop frame
downward. Release pin when it lines
up with locking hole that is drilled into
the M661 frame.
Step 1
Install by placing hoop frame at an
angle over the top front channel bar
of the M661 frame, so that the top of
hoop frame “hooks” into place.
Installing the Mini Autofeed on to the M661
The Mini Autofeed-Retriever needs
to be mounted on a hoop that ts
on to the M661:
• Our large hoop (LH) ts over a
reel of 1/2”cable
• Our small hoop (SH) ts over a
reel of either 3/8"or 5/16" cable
The hoop frame is designed to be
added or removed quickly and can
be installed or removed with the
Autofeed mounted– if desired.
The Autofeed can be easily
removed from the hoop for
changing reels of cable or for easy
access to revolving“feed” arm.
Elephant Trunk
An extension “elephant” trunk
is available for the front of the
Auto Feed. The trunk is 4 feet
long and is useful for guiding
cable into overows or when
operator is unable to place
machine near clean out.
Step 4
Tighten thumb screw on the
bottom of the hoop bracket to lock
Autofeed in place.
Step 3
The Autofeed attaches to the hoop frame
via the bracket mounted onto rear of the
Autofeed. Slide this bracket into channel of
the mounting bracket on the front of the
hoop frame.

If the cable resists going forward or backward, then one of
several things is occurring:
• You are hitting an obstruction. However, if torque does
not start to build, you may be at an elbow or the blade
may be hitting an oset or break in the sewer line. Apply
some forward pressure manually to help you gure out
what it is there.
• The Feed Wheels are worn and need replacing.
• There is debris hanging onto the end of cable and blade
that is resisting retrieval. In this case manually help the
Autofeed pull the cable back into the reel. Clear blade of
debris and run cable through sewer line again to make
sure all blockages are removed.
Obstructions
When your blade nds an obstruction it will usually stop
the rotation of your cutting blade. If the blade does not
release after several seconds of torque:
• Move the Autofeed lever to the “R” (reverse) position
• Read the instructions from your machine’s User Manual
for releasing a stuck blade
The most ecient cleaning is achieved by learning how to
use torque build-up in your cable without over-torquing to
the point of damaging cables or blades.
Finishing Up
When the obstruction is removed, place the Autofeed/
Retriever fully in the “R” position until you hear the blade
nearing the pipe opening. Disengage Autofeed (by turning
screw knob to the left) shut o machine and pull the blade
out of the pipe opening.
General Operation
NOTE: MyTana machines tend to push cable forward, out
of the machine. For this reason, we recommend manually
feeding the cable into sewer lines rather than using the
Autofeed only to advance the cable.
Be sure to read the User Manual that came with your M661
before operating the machine with the Autofeed-Retriever.
1. Disengage Autofeed (by loosening
screw knob on top cylinder)
2. Insert cable into pipe opening several
feet before turning on machine.
Never insert a spinning blade
into a sewer line!
If you choose to use the Autofeed for pushing cable into
the sewer line, move the feed lever about 10 degrees
toward the “F” and turn on your machine.
Turn the screw more knob on the top
cylinder to the right until the cable starts
to move forward. DO NOT tighten the
knob more than is required to move
the cable forward.
Push lever fully into the forward position.
Proceed with caution, keeping in mind
that it is essential that the cutting blade not be forced
through an obstruction using the forward force of the
Autofeed.
uDo not run cable ttings (couplings, splicers,
cable ends) through a tightened down Autofeed,
it can break feed wheels. Disengage the Autofeed
(turn screw knob to the left), pull ttings through
manually and then re-engage.
Spacers
The spacer plates at the bottom end of the
lower two cylinders on the Autofeed deter-
mine the proper spacing to maximize the grip
of the drive wheels on your cable. Normally,
the correct spacing is preset for the cable
you will be using. However, double-check to
make sure that the spacing is correct, or adjust
accordingly by using the chart. See schematic if
adjustments are required.

Helpful Tips
The following tips will add life to your cable, blades and
Mini Autofeed-Retriever.
• Avoid turning down the screw knob on top cylinder of
feed too tightly. Turn knob only as far as needed to move
cable back and forth. Over tightening can:
– cause excessive wear on cable and, if extreme
pressure is applied can impede the proper rotation
of the cable through the Autofeed
– cause the cable to stack loosely into the reel when
retrieving, rather than stacking the cable snugly
against the outer walls as it should
– break feed wheels
• Do not run cable ttings (i.e. couplings, splicers, cable
ends) through a tightened down Autofeed, it can break
feed wheels. Release the Autofeed, pull ttings through
manually and then re-engage.
Bulb-Head Cable
Cable that is expanded at the front
(often called bulb-head or open-hook)
may require larger openings through
the feed wheels than the
normal spacing of the
wheels allow.
To accommodate this, a removable
plastic wing nut is used with a
mounting bolt on the bottom
right cylinder of the Auto Feed.
Remove the wing nut and bolt then
swivel the cylinder downward. This
creates a large enough opening so
the wide head of the BH or OH
cable can slide through.
Once the larger head is
through the feed, swivel the
cylinder upward and replace
mounting bolt and wing nut.
Routine Maintenance
• Watch for wear on drive wheels (bearings) and pins.
• Make sure drive pins stay in designated slots on
movement disc.
• Remove debris (i.e. rags, string, hair) from cable before
running through the Autofeed. This kind of debris can
clog up the Autofeed wheels and movement parts
rather quickly.
• If Autofeed is not to be used for a period of time,
lubricate before storage
Lubrication
As with any mechanical device, proper care will maximize
the life of your Mini Autofeed-Retriever. Keeping it clean
and properly lubricated is essential.
The Feed unit has been greased at the factory. However,
routinely continue to grease all housings equipped
with zerks (grease ttings).
Remove front disc periodically, clean and lubricate. Free
movement of the front disc is crucial to proper movement
of cylinders and drive wheels.
Replacing Drive Wheels (also called Drive Bearings)
See parts breakdown on next page for reference
1. Remove Autofeed from cable machine
2. Remove 6 acorn nuts / lockwashers from front panel
3. Remove front disc and movement assembly
4. Slip cylinder housing Part MSF106 (whichever one
that needs new drive wheel) from hex bolts
5. Remove piston Part MSF107 from housing (it will
lift out of housing)
6. Remove clip spring that holds drive pin
7. Carefully pull out drive pin Part MSF111
8. Remove spacers and drive wheels
9. Clean all parts in cleaning solvent before reversing
procedure to install new drive wheel(s).
NOTE: It is a good idea to clean up the cylinder housing
at the time that you change drive wheels. There is a
thrust bearing with races at the bottom of each cylinder
that needs to be cleaned periodically. These parts can
be accessed by removing the spacer plates and end
cap at the bottom of the housing.
