INTRODUCTION

OPERATOR’S MANUAL

MODEL TC700M/MC TENDERIZER

The ROSS TC700M/MC Tenderizer is a blade-type mechanical tenderizer. The ROSS
blades are narrow and very sharp so that they actually cut their way through meat tissues and
fibers and not merely punch holes by finding paths of least resistance. The special stainless
steel alloy blade has a tensile strength of approximately 300,000 pounds per square inch
which provides exceptional edge durability combined with extreme toughness. The ROSS
Tenderizers can process bone–in meat that is up to 7” high and 12” wide. The most
significant technological breakthrough in mechanical tenderizers has been the ROSS system
for tenderizing meat with the bones left in.

The ROSS blades are actuated by magnetic head plates so that each blade is actually
driven through the meat by magnetic force. These head plates consist of a sophisticated
array of rare-earth magnets and special electrical steel pole pieces. The magnets provide just
enough force to drive the blades through the toughest meat, but no more. When a ROSS
blade hits anything tougher than meat, the magnetic force is overcome and the individual
blade simply stops trying to penetrate – the blade is, therefore, undamaged and the other
blades are allowed to fully penetrate the meat.

The 700M/MC Tenderizer provides the utmost in safety to operating personnel by
incorporating pivoted guards that completely cover the operating area of the Tenderizer.
Magnetically operated switches are built in the guard mechanism in such a manner that both
guards must be closed before the machine will operate. If either guard is opened while the
machine is running, power will be removed from the main motor and all operation will stop.

2 DESCRIPTION

2.1 MECHANICAL

When the 700MC is turned on with the guard(s) in the closed position, the head assembly reciprocates.
The conveyor advances when the blades are fully retracted at the top of each stroke.

The meat to be tenderized is simply placed on the conveyor. The powered conveyor advances the
product under the blades. Any blade that strikes a bone will automatically stop its downward stroke while
the other blades will continue to penetrate the meat. As the blades return to the top of the stroke, the
retracted blades are pushed back into position by the soft plastic reset pads.

The blade assemblies are mounted between two “H” shaped stainless steel frames, the head frame and
the guide frame. The head frame is bolted to the top of the one and one-half inch diameter main
uprights. The guide frame is mounted below the head frame on the smaller one inch diameter guide
uprights.

The main and guide uprights extend through the top of the cabinet and are guided by oil-impregnated
bronze bearings. These bearings are held in the main frame casting that is bolted to the underside of the
top of the cabinet. The lower ends of the main uprights are bolted to the cam plate. This is driven by a
cam roller attached to the crank cam on the output shaft of the transmission. The transmission is driven
by a two horse power electric motor. The lower ends of the guide uprights extend through the toggle
clamp assemblies and guide raisers. The guide raisers with their cushions are attached to the main
uprights and the clamp pivots are attached to the guide uprights.

As the 700MC makes its downward stroke, the head and guide frames descend until the guide frame
contacts the meat. At this point, the guide frame stops while the head frame continues downward to the
bottom of the stroke. The guide frame is locked on the stationary toggle rods by the toggle assembly.
This holds the meat down on the conveyor belt as the head frame travels upward withdrawing the blades.
As the main uprights and the guide raisers reach the clamp pivots at the position where the guide frame
had been locked, the unlock cushion lifts and levels the toggle clamp. With the toggle clamp level, the
toggle rings release allowing the guide uprights and guide frame to rise to the top of the stroke.

The crank cam also actuates the cam follower assembly and rocker arm for the conveyor advancement.
The cam follower causes the rocker arm to pull down on the pull rod, operating the bell crank. The bell
crank causes the push rod to operate the index arm. As the index arm moves, the pawl on the index arm
engages a tooth on the index wheel causing the conveyor to advance one increment. As the index wheel
advances, a serpentine track on the cam drive wheel causes the conveyor to move side to side
producing the proper interdigitation of the blades to maximize tenderization. The crank cam is designed
to have the rocker arm and conveyor drive advance the conveyor just as the head assembly is near the
top of its stroke with the blades out of the product.

2.2 ELECTRICAL

The electrical control system is located in a sealed compartment at the input end of the Tenderizer
cabinet. The control system includes a control transformer, fuses, motor starter, phase sensor, and relay.
The electrical schematic, MN045770, is located at the rear of this manual. The incoming three-phase
power is connected between terminals 1, 2 and 3 of the main terminal block. It is then fed through the

MN700-MC0010

2-1

disconnect switch (S1) to the line terminals L1, L2 and L3 of the motor starter (K1) and to terminals 3, 4,
and 5 of the phase sensor.

A single-phase connection from the incoming power is applied to the primary of the control transformer
(T1) through fuses F2 and F3. The control transformer is designed with tapped primary and secondary
windings allowing it to be connected such that a control voltage of approximately 120 VAC may be
obtained from a wide range of line voltages. The 120 VAC control voltage is used to energize the coils of
the motor starter (K1) and relay (K2) as well as the head adjusting motor circuit.

Power from the secondary of the control transformer is fed through the POWER switch (S2) to fuses F4
and F5. The load side of fuse F5 is connected to terminals 1 and 8 of relay K2 and to one side of the
START switch (S3). With the machine connected to the proper electrical power source, the disconnect
switch turned on and the POWER switch pulled out, pressing the START switch will energize relay K2
through guard switch S7 providing the guard is closed. When K2 pulls in, contacts 8 – 6 of K2 feed 120
volts to one end of the motor starter’s coil (K1) and contacts 1 - 3 latch K2 in allowing the START switch
(S3) to be released. S8 is an E-stop switch mounted at the rear of the machine.

Although the vertical reciprocating motion of the Tenderizer head is unaffected by the rotational direction
of the main drive motor, if the motor was to operate in the reverse direction, the drive to the conveyor
would occur with the blades partially down. Under these conditions, the conveyor would attempt to move
with the blades still inserted in the product. To prevent this from happening, a phase sensor (A1) is
incorporated in the electrical system to keep the motor starter from being energized unless the incoming
power is correctly phased.

Terminals 3, 4, and 5 of the phase sensor are connected to the incoming power allowing the phase
sequence to be sensed. If they are in the correct sequence, an internal solid state relay connects
together terminals 1 and 8 of the phase sensor. Terminals 1 and 8 are connected in series between the
return side of the motor starter’s coil and the 0 volt connection fromT1, thus with the proper power
phasing, the motor starter will pull in applying the three phase power to the main motor and the machine
starts operating.

120 volts from the transformer through the POWER switch and fuse F4 is applied to the bridge rectifier
(CR1). The DC terminals of CR1 are connected to the head adjusting motor through the HEAD
ADJUSTING switch (S4) and limit switches (S5 and S6). S4 is a two position switch with four contact
blocks connected so as to allow reversal of the polarity of the DC voltage that is applied to the head
adjusting motor (M2) through terminals 4, 5 and 6. One side of M2 is connected to terminal 4 while the
other side of the motor is connected through the limit switches (S5 and S6) to terminals 5 and 6. The
HEAD ADJUSTING switch has no ‘off’ position, when either the HIGH or STD positions are selected, the
motor will operate until the head assembly reaches the selected position and the appropriate limit switch
opens.

Once started, the tenderizer will continue to operate until either the disconnect switch is turned off, the
POWER switch is pushed in or one of the guards is opened. Restoring any of these devices will NOT
allow the machine to start, the START switch must be pressed.

3 INSTALLATION

3.1 UNCRATING

The 700MC Tenderizer is shipped in an enclosed crate. The Tenderizer is supported by a wooden skid
with wooden framing at the ends of the cabinet. The overall assembly is covered with clear polyethylene
film and placed in a complete wooden crate.

Prior to uncrating the Tenderizer, inspect the condition of the packing material; any external damage may
have resulted in damage to the Tenderizer itself. After the Tenderizer is uncrated and removed from the
skid, it should be thoroughly checked for visual damage to the cabinet, casters, safety guards and the
head assembly.

Any damage to the Tenderizer should be reported to the shipper immediately. If the external packing
material had been disturbed or torn and visual damage to the Tenderizer itself can be seen, the
Tenderizer should not be uncrated until the shipper’s representative has been notified.

The Tenderizer is uncrated by first removing the top and sides of the crate and then cutting the two steel
bands that hold the base cabinet to the wooden skid. The 2 x 4 end brace is removed from end of the
skid frame. The Tenderizer must then be lifted slightly by prying between the side rails of the skid frame
and the bottom edge of the base cabinet.

As the cabinet is raised, the support blocks under each end can be removed and the Tenderizer lowered
on the skid with the casters supporting it. Before lowering the cabinet, the casters should be aligned so
the Tenderizer can easily be rolled from the skid. Use the 2 x 4 end brace that was removed as a step
ramp at the end of the skid and roll the Tenderizer slowly from the skid to the floor, being careful not to
damage the casters.

3.2 INSTALLATION

The 700MC Tenderizer does not need any installation, as such, since it is considered a portable
electrically operated appliance and need simply be rolled into position, have its power cord plugged into a
suitable outlet, and it is ready to operate. There are, however, certain site requirements to consider. In
as much as the Tenderizer weighs 1,000 pounds and is mounted on casters, the floor on which it is to
operate must be sound, level, and capable of supporting the Tenderizer, as well as the operating
personnel, meat lugs, etc.

The casters that are furnished with the Tenderizer are designed to support its weight, as well as the
shock loads that may be transmitted to them during the normal operation of the machine. The casters
allow the Tenderizer to be moved around on any hard, smooth-surfaced floor. Rolling the Tenderizer
over uneven floors or over cracks or expansion joints in the floor will greatly shorten the life of the
casters. Prior to the actual failure of the casters, they will cease to swivel properly, resulting in extreme
difficulty in moving the Tenderizer even on a smooth surfaced floor.

If it is necessary to move the Tenderizer over poor floor surfaces, as much care as possible should be
used to avoid excessive shock to the swivel axis of the casters. When moving the Tenderizer, it should
be pushed or pulled by the cabinet and NOT by the safety guards or head assembly. Any attempt to

MN700-MC0010

3-1

move the Tenderizer by pushing or pulling on the guard assembly can result in misalignment of the
guards. This can result in the safety switches being inoperative, which would prevent the Tenderizer
from operating.

3.3 ELECTRICAL REQUIREMENTS

The Model 700MC Tenderizer can be supplied to operate from any of the standard world wide three
phase line voltages. This would include the following: 208, 220, 230, 240, 380, 415, 440, 460, 480 and
575 volts. The supply frequency can be either 50 or 60 Hz. When the Tenderizer is ordered, the actual
plant line supply must be stated, such as 225 volts at 60 Hz. The tenderizer would then be properly set
up to operate from that electrical supply. A subsequent deviation of up to plus or minus 10% would have
little or no effect on the operation or longevity of the Tenderizer. An exception to this would be to place
an absolute minimum on the operating voltage at 200 volts.

The main drive motor in the 700MC tenderizer will operate from line voltages of 208 through 480 volts at
either 50 or 60 Hz. A different motor is required for operation from 575 volt lines. Changing the
Tenderizer for operation on any voltage between 208 and 480 volts requires only minor changes and can
easily be done in the field. Changing to operation from 575 volt lines requires replacement of the main
drive motor. Replacement of the motor can certainly be done in the field, but it is somewhat involved as
the cam and transmission must be removed to gain access to the motor. Machines supplied for
operation from 575 volt lines are furnished with a motor and transformer designed for that specific
voltage.

The various items that may need to be changed or reconnected to match a particular line voltage are: the
motor itself, the heaters and overload in the motor starter, the phase sensor and line cord. The chart on
page 3-4 illustrates the various items required for different line supplies. The numbers after MAIN
MOTOR refers to the part number of the motor required for the selected supply. The MOTOR WIRING
refers to the connections in the motor junction box for the selected supply. The actual connections are
given on the motor’s nameplate. The numbers after the HEATERS, PHASE SENSOR, LINE CORD
ASSEMBLY AND FUSES refer to the part numbers of the affected parts. The OVERLOAD SETTING
gives the required adjustment of the overload on the motor starter and is given in percentage
corresponding to the dial markings on the overload.

The overload section of the motor starter provides running overload protection for the main drive motor.
Fusing the primary and secondary of the control transformer provides protection of the control circuits
and the head adjusting motor. There is no protection from direct short circuits in the main motor, this
must be provided by the proper external branch circuit protection as defined by the applicable electrical
codes relating to a 2 HP three phase motor.

When operating from any of the low voltage ranges (200 – 240 volts), the branch circuit should be
protected to 20 amps with either dual element (time delay) fuses or a motor rated time delay three pole
circuit breaker. The correct receptacle to be used would be one that meets NEMA L15-20R. The branch
circuit protection required for any of the higher voltage ranges should be 20 amps with either dual
element (time delay) fuses or a time delay circuit breaker. The correct receptacle to be used would be
one that meets NEMA L16-20R for 440-480 volt lines or L17-20R for 575 volt lines.

The Tenderizer is furnished with a power cord made from approximately twenty feet of SO – 4/12 and
terminated with the appropriate plug cap. Substitution of the supplied plug cap with a non-approved type
is entirely at the owner’s risk and any consequence that may result is the owner’s responsibility.

MN700-MC0010

3-2

NOTE - Always turn the main power switch OFF before connecting the machine to a power source. If

the machine is plugged in with the main power switch ON and the head adjusting motor operating, the
primary transformer fuses may blow. This is due to the high magnetizing in-rush current of the
transformer added to the reflected starting load of the motor

.

3.4 POWER PHASING

As with all three-phase motors, the phase sequence of the incoming power determines the direction of
rotation of the motor in the Tenderizer. Although the vertical reciprocating motion of the Tenderizer head
is unaffected by the rotational direction of the motor, if the motor was to operate backwards, the drive to
the conveyor would occur when the blades were partially down. Under these conditions, the conveyor
would attempt to move with the blades still inserted in the product. To prevent this from happening, a
phase sensor is incorporated in the electrical system to prevent the main motor’s starter from being
energized unless the incoming power is correctly phased.

After the Tenderizer has been set up and made ready to operate, the phasing of the incoming power
should be checked. Plug the power cord into the receptacle provided and pull the main power switch out
to the ON position. With the guard completely closed, press the START button. If the machine starts
and continues to operate, the phasing of the incoming power is correct and no further changes are
necessary. However, if when pressing the START button nothing happens, the phasing of the incoming
power may be incorrect.

To correct the phasing, two of the conductors in the power cord must be interchanged. If a separate
branch circuit disconnect box is provided for the Tenderizer, then it would be best to interchange two of
the wires inside the box; however, if the same circuit is used for other machines that are phase sensitive,
then the correction will have to be made in the plug cap on the Tenderizer’s line cord. Disassemble the
plug cap and interchange any two of the main conductors (black, white, or red wires). Do NOT change
the position of the GREEN wire; this is the ground wire and connects directly to the cabinet of the
Tenderizer. Connecting this wire to any other position in the plug cap would result in the Tenderizer
cabinet being electrically “hot” with respect to the building ground, an extremely dangerous condition.

After correcting the phasing of the incoming power, check the operation of the Tenderizer again. If it still
fails to operate, refer to the TROUBLESHOOTING section of this manual

6 OPERATION

6.1 MACHINE OPERATION

NOTE: The 700MC Tenderizer will not operate unless the safety guard is closed.

Once the Tenderizer has been correctly installed and properly phased, the operation is extremely simple.
A. Connect the line cord to a suitable source of power.
B. Turn the Disconnect switch located near the center of the electrical access panel, to the ON

position.
C. Pull out on the red “POWER” switch.
D. Select either the “STD” or “HIGH” position on the Head Adjust switch.

This switch selects the range of product thickness that the tenderizer can accommodate. In the
“STD” position, boneless cuts up to 7 1/2” thick or bone-in cuts up to 7” can be processed. The
“HIGH” position allows cuts up to 9 1/2” to be processed, however in this position the blades only
reach to 2” above the conveyor on their downward stroke requiring the product to be at least 4” thick
and it is necessary to turn it over for a second pass through the tenderizer to provide complete
tenderization.
motors are operating may cause the main motor to turn off. You should wait for the head adjusting
motor to reach its destination and stop before changing the switch position.

E. Place the meat centrally on the conveyor.

CAUTION: ATTEMPTING TO PROCESS MEAT THICKER THAN MACHINE CAPACITY OR
FORCING MEAT UNDER THE HEAD WILL SERIOUSLY DAMAGE THE MACHINE.
NEVER CHANGE THE HEAD ADJUST SWITCH FROM THE “HIGH” TO THE “LOW” POSITION
WHILE PROCESSING PRODUCT THAT IS OVER 7 1/2” HIGH OR WHILE SUCH PRODUCT IS IN
THE MACHINE.

F. Press the green “START” button. The tenderizer will start and continue to operate until stopped
by pushing in on the “POWER” switch.

G. Meat less than one and one half inches thick may not be held in place properly by the guide

frame. Better and more rapid tenderizing will be obtained if such thin cuts are stacked to near
machine capacity.

H. It is desirable to keep the conveyor belt filled with meat without any gaps between cuts. Not only
does this maximize production, but it also assures that the meat moves intimately with the
conveyor and avoids the possibility of over-processing as a result of slippage.

I. To stop machine, push in the red knob on the “POWER” switch. The machine can also be
stopped by turning the disconnect switch to the OFF position or by opening a guard. The
tenderizer will NOT restart with either of these returned to their operating condition, the “START”
switch must be pressed.

NOTE – Changing the position of this switch while the main and head adjusting

6.2 CLEANING AND BLADE REPLACEMENT

The Tenderizer should be cleaned DAILY with a mild detergent and hot water or steam. The machine is
fully sealed and may be liberally flushed without fear of damage. Approved detergents (between 4.5 pH
and 10 pH) used in proper concentrations will not damage the finish even though allowed to remain for
prolonged periods. However, immediate clean water or steam rinsing is recommended. DO NOT USE
CAUSTIC CLEANING SOLUTIONS since these may damage the magnetic head plates and seals. The
following is the necessary DAILY cleaning procedure:

1. Stop the machine near the top of the stroke.

2. Turn off the disconnect switch or disconnect power cord.

3. Flush the entire machine with clean hot water or steam concentrating on the blade assembly.

4. Remove the Blade Assemblies:

• Remove the detent pins and remove the lower outer guide bars first.

• While holding the blade assembly in place, loosen the detent pins and remove the upper outer guide

bars.

• Slide the blade assembly out. HOLD BY RETAINING RODS OR TOP ONLY. NEVER PLACE

HANDS UNDER THE HEAD ASSEMBLY.

• Remove the two acorn nuts on top of the reset plate using a 1 1/8” wrench.

5. The blade assembly can now be taken to a separate cleaning station and immersed in a mild

detergent solution (100% immersed.) The use of a plastic tub is recommended so as not to damage

the sharp edge of the blades.

DO NOT SET BLADE ASSEMBLY (WITH BLADE TIPS DOWN) ON ANY METAL
SURFACE.

The following is the recommended cleaning process:
A. Soak blade assembly for a minimum of 15 minutes with a mild hand agitation every 5

minutes. USE CAUTION WHEN HANDLING THE SHARP BLADE TIPS!

B. After soaking, clean the blade assembly with a brush paying attention to the top of the

blades, magnetic head plates and lower blade guides.
C. Rinse blade assembly with clean hot water or steam.
D. Visually inspect blade assembly paying attention to areas where the blades move through

the magnetic head plates, guides and tops of blades. If any contamination is found, repeat

the above steps.
E. Sanitize blade assembly (maximum time in sanitizer 5 minutes).
F. Blow dry blade assembly.

6. Oil blade assembly with Ross 601 white mineral oil (or equivalent) paying particular attention to the
tops of the blades and magnetic head plates. While the blade assemblies are out, the entire
machine can now be cleaned with detergent, or steam and a bristle brush.

SPECIAL ATTENTION SHOULD BE GIVEN TO THE UNDERSIDE OF THE GUIDE FRAME.

MN700-MC0010

6-2

7 The machine’s belt can be manually moved without the blade assemblies in place to allow for the
cleaning of the belt with a spray of soap and water. Inspect conveyor belt for damaged sections and
replace as required.

8. Reinstall the blade assemblies by sliding the head plate into position on the head frame making sure

that the rib on the magnetic head carrier is positioned in the corresponding slot on the head frame.

9. Install the upper outer guide bar (‘top’ marked on bar – slot goes down)

10. Then slide the lower blade guide into position on the guide frame and install the lower outer guide

bar. To accomplish this sometimes it is necessary to slightly lift the lower blade guide USE CAUTION

NOT TO PUSH HANDS INTO THE BLADES AT THE BOTTOM OF THE LOWER BLADE GUIDES.

11. Check that the installed head assembly moves freely in its installed position. It should slide within the

slots on the guide bar and head/guide frames.

12. Reinstall the Reset Plate and fasten with the original acorn nuts and washers. Tighten to a torque of

50 ft lbs.

13. After every cleaning, spray the blade assemblies, tops of the blades, main uprights and guide

uprights with ROSS 601 white mineral oil (or equivalent).

INSPECT MAIN RETURN SPRINGS FOR CONDITION AND PROPER

ATTACHMENT. WITHOUT MAIN RETURN SPRINGS IN PLACE, THERE IS A DANGER

OF THE DRIVE MECHANISM MOVING ON ITS OWN WEIGHT

WHEN THE MACHINE IS STOPPED WITH THE HEAD IN THE UP POSITION.

The cam plate and cam roller should be lubricated with a high quality, water-resistant grease, such as
Chevron SR1 Grease - 2.

NOTE:

The two grease fittings on the cam plate for the Dual Height Range Option Kit must be lubricated every
month. One or two pumps from a grease gun containing Chevron SR1-2 or equivalent should be
sufficient.

The cover panel on the conveyor box should be removed and the cam drive wheel should be lubricated
with Chevron SR1-2 (or equivalent).

EVERY SIX MONTHS OR 500 HOURS OR OPERATION

The side panel should be removed and all moving parts, except the cam plate assembly, should be
sprayed with Ross 601 oil.

ONCE A YEAR
The oil level in the transmission should be checked. To check oil level, remove the oil level plug on the

far side of the transmission from the main side door.

To add oil, remove the plug on the top of the transmission and fill with USP extra-heavy white mineral oil
(Ross Oil No. 15040014, or Exxon Primol 355, or equivalent) until oil level is even with the oil level plug.
Replace the plug on the top and the side of the transmission.

To drain the oil a drain tube may be used from the drain plug on the side of the transmission and placed
through the drainage hole nearby in the bottom of the tenderizer cabinet.

7.3 ADJUSTMENTS/SPECIFIC REPAIRS

Conveyor link belt may stretch after use. Do no allow conveyor chain to drag on the tenderizer cabinet.
To tighten belt use adjuster screws item number 33 shown on page 5-5 of this Instruction handbook. If
there is still too much slack, remove one of the belt links.

Do not allow the chain drive for the height adjusting mechanism to become too loose. If the chain gets
loose enough to skip a tooth on the sprocket, a complete readjustment of the height mechanism would
be necessary. See “Head Height Adjustment” on next page.

7.3.1 CONVEYOR BOX

This is how the conveyor box should appear when
the conveyor is at rest and not advancing. The index
arm and pawl has pivoted back almost far enough to
drop behind a second tooth. The pull rod (see page
5-11), shown going though the bottom of the box, is
being pushed up by the conveyor return spring
located inside of the cabinet, and the bell crank is
resting against the bell crank stop bolt. See figure
on page 5-4.

When the conveyor is fully advanced the index arm
is pointing almost straight down.

When set as shown, the conveyor should advance
correctly when loaded with product. See the
troubleshooting section for problems concerning the
conveyor drive system.

MN700-MC0010

7-2

7.3.2 HEAD HEIGHT ADJUSTMENT

(blade-to-belt clearance)

The blade to conveyor clearance has been set at the factory and should not change as a result of normal
use. Although unlikely to occur, there are several reasons why this mechanism may need to be checked
or adjusted:

• If the blades are coming in contact with the conveyor tray or belt.

NOTE: It is normal for the blades to

just touch the knuckle part of the conveyor belt. Some “float” is inherent to the blade design, so that
the blade will push up .030 to .060 inches ,(.8 to 1.5 mm), before applying pressure on the blade
point.

• If the blades are not coming close enough to the conveyor belt in the standard position.

• If the blade height adjustment mechanism has to be repaired, or if the adjustment chain slips, (this

will normally bind up the high low mechanism).

To check for proper head height the following step must be followed:
The diagrams referred to below in parenthesis are located in the MACHINE INFORMATION section of

this Information Handbook.

• Set HEAD ADJUST to the STD (standard) position

• Jog (stop and start) machine until head is stopped as close as possible to the down position

• Disconnect power to machine

• Remove the main side cover

• Use a 9/16 inch wrench or socket on the nut welded to the back of the gear box drive motor. Turn the

electric motor until the cam roller (p5-7, item 9), is located directly below the gear box output shaft.

The height of the head frame is controlled by the adjustment of the roller switches, (p5-10, item 29).
They are mounted on a switch bracket, (p5-10, item 36). By slightly loosening the two securing screws,
(p5-10, item 16), the whole bracket can be carefully shifted in the direction of desired adjustment. DO

NOT OVER-RUN ROLLER SWITCH BY FORCING BRACKET IN THE DIRECTION OF A ROLLER
SWITCH BEING CONTACTED. The best way to adjust the switch(es) is given here by the following

example.

EXAMPLE - The head is in the standard position and stopped all the way at the bottom of the stroke

as detailed above. The blades are too low. Turn the HEIGHT ADJUST switch to the HIGH position while
watching the blade to belt clearance carefully. When the blades show the proper clearance to the belt,
push in the EMERGENCY STOP button. Disconnect the power and remove the main side door to the
cabinet. Slightly loosen the switch bracket securing bolts and gently pry the switch bracket in the
direction of the closest roller switch. Listen closely for the switch to close. Tighten the bolts and replace
the side door. Turn on the machine and allow the head to be raised by the height control motor enough to
be sure the guide raiser (p5-10, item 18, actuates roller switches) has cleared the switch. Change the

MN700-MC0010

7-3

switch to the STD setting and observe blade to belt clearance when the head stops its’ travel. Re-adjust if
necessary.



The adjustable main upright(s) (p5-11, item 44) should never thread too far into the elevator nut(s)
(p5-8, item 7). There should always be 2 to 4 threads showing in the STD position.

 CRUSHING HAZARD 

TAG OUT, LOCK-OUT POWER. ROTATION OF DRIVE COMPONENTS

WHILE INSIDE TENDERIZER COULD BE FATAL

 CRUSHING HAZARD 

INSPECT MAIN RETURN SPRINGS FOR CONDITION AND PROPER

ATTACHMENT. WITHOUT MAIN RETURN SPRINGS IN PLACE, THERE IS

DANGER OF THE DRIVE MECHANISM MOVING FROM ITS OWN WEIGHT

WITH THE MACHINE STOPPED WITH THE HEAD IN THE UP POSITION.

7.3.3 HEIGHT ADJUST CAM MECHANISM

The cam assembly is shown on page 5-8. Under normal conditions the DC amperage draw during the
function of the high low motor should not exceed the 1.5 amps shown on the motor nameplate. This is
checked on every tenderizer from the factory with amperage ranges normally between .7 to 1.25 amps.
The following conditions will effect this function:

1. If one main upright is set higher that the other, the high low mechanism will be overworked and will
eventually fail. This will only happen if the chain has slipped on one of the lift sprockets . To check
for level of the main uprights, remove the head frame and check across the tops of the main

uprights with a straight edge. Disconnect the chain and turn one of the lift sprockets to even main
uprights. Reconnect chain and tension.

2. If the high low mechanism is not used on a regular basis, the grease will harden and increase turning
resistance.

3. If the chain is adjusted too tight extra effort will be required to turn the mechanism

4. The main uprights must not be allowed to thread too far into the elevator nuts.

Always make sure that the main return springs (p5-9, item 3, p5-10, item 27) are in good condition and
firmly attached to their mounts.

7.3.4 RESET PAD/PLATE CLEARANCE

These soft reset pads push the blade assemblies which have been released from their magnet carrier,
(p5-3, item 1), to within the magnetic forces of the magnet carrier. They then will be pulled into place by
these magnetic forces. If clearance does not exist and the soft reset pads where to be pressed against
the end of the blades, eventually the reset pad will be destroyed. Once perforated or torn, the reset pad
becomes a place for bacteria and can even damage blade assemblies with this extra force.

MN700-MC0010

7-4

After the head height has been set correctly, the clearance between the tops of the blade assemblies,
(p5-3, item 6), and the reset pad, (p5-2, item 2), should be checked. To do this, run the head assembly
to the top of the stroke. Open the pivoting guard, (p5-1, item 1), and look for a space between the blade
assembles tops and the bottom of the reset pad. Hold onto each retainer bar, (p5-3, item 3), in turn and
try to move the head assembly magnet carrier within its’ mounting slot. The head should move around
easily without the blade assemblies touching the reset pad. There should be no greater clearance than
approximately .06 inches, (1.5 mm), between the tops of the blades and the reset pads.

To correct clearance add or delete shim washers between the top of the reset plate studs, (p5-2, item

16) and the reset plate. Shim washer numbers are:

• 11451009................................................. Washer, flat 3/4 id x .032 thk

• 11450116................................................. Washer, flat 3/4 id x .092 thk

There may already be washers on top of the reset posts to adjust the height of the reset plate. The 700M
is carefully adjusted at the factory. If, for any reason, the reset plate, head frame or guide frame is
removed from the machine, be sure to keep track where each shim washer goes. During reassemble,
make sure that the washers go back in exactly the same position.

7.3.5 TOGGLE RING REPLACEMENT

A. Disconnect the machine power cord. Remove the side

cover panel.
B. Rotate motor coupling (in direction of arrow) until head
assembly is in full down position.

C. Remove unlock cushion
D. Remove pivot pin, turn toggle clamp and remove from

shaft

E. Remove toggle ring retainer plate and toggle ring
F. Install new toggle ring; replace toggle ring retainer

plate.

NOTE - Always install new toggle rings on both sides.

G. Replace toggle clamp. Install pivot pin

Make sure snap rings are in position

H. Check the snap ring position on the guide uprights. There should be one snap ring above and one
below the clamp pivot, the snap rings go in the lower two grooves on the guide uprights

MN700-MC0010

7-5

I. Replace unlock cushion
J. Make sure that the guide raisers (page 5-10, item 18), on the main uprights, are seated all the way
down on the stabilizer bars and spacers (page 5-11, items 29,30)
K. Make sure toggle assembly is centered on toggle rod.
L. Check mechanism for free movement. Toggle assembly should pivot up and down approximately 1/8".
M. Turn motor coupling (in direction of arrow) so machine makes two complete cycles. Check for proper

clamp and guide operation throughout cycle.
