Gag Feed Program
The standard “GAG” feed program is a multiple feed length program within a specified
job number. The different programmed feed lengths will be referrred to as sequences.
Each sequence can be repeated many times with a choice of using any combination of
8 outputs per sequence . For each output there is an input that can be used to verify
that the output device has moved. Although this is the standard program, Rapid-Air
can program other configurations in any combination to meet the customer’s
requirements.
The standard “GAG” feed program has 10 jobs with 10 programmable sequences per
job. Each sequence can be a different feed length which can be repeated up to 99
times. The following chart depicts the previous write-up.
GAG FEED
TOTAL JOBS 10
TOTAL SEQUENCES 10
TOTAL REPEATS 99
TOTAL OUTPUTS 08
TOTAL INPUTS 08
The job, sequence, repeats and outputs are software programmable. The output will
activate when the sequence is activated and remain activated until the next sequence.
The input will be checked when a press mounted switch is momentarily activated, at
this time, if the programmed inputs and the outputs do not match then a fault will be
displayed on the screen, automatic will drop out and the press should preform an
emergency stop. The operator’s manual will explain how to activate and use the inputs.

INTRODUCTION
The Rapid-Air Servo feed carries with it the quality and reliability you have grown to
expect from a Rapid-Air product. The motion control system is a programmable
industrial computer and this advanced technology married to a highly engineering
precision roll feed, is an unchallanged combination in the stamping industry.
The compact mechanical package, direct coupled with a brushless servo drive motor,
offers response and feed accuracies unparalled in any other powered roll feed.
Operator interface is so simplified, a typical setup person can have the Rapid-Air servo
feed programmed and running in a matter of minutes. A step by step prompt, on the
four line 80 character display, asks simple questions of the operator. Entry of feed
length, strokes per minute, feed arc, and pilot are all that is required for a new setup.
Routine jobs can be stored, recalled, changed and saved or run with a simple 2 digit
job number entry. Up to 10 jobs and 10 sequences per job may be stored and recalled
at will.
Operator programmed feed length, up to 999.999 inches and % max speed selection
along with full jog features, allow the operator to thread the material and inch it into
position. The inch feature enables the operator to jog the servo feed forward or
reverse at a slow rate or the operator can program the jog distance at any jog length
from .001 to 9.999 inch incremental moves for precise postioning in the die.
The precision mechanical roll feed unit has been designed for compactness, ease of
setup and installation. A 230 volt, 3 phase supply and an air line are all that is required
of the customer. Two cables with twist lock plugs and one or two cables for the air
valve control are supplied with the control and need only be connected to the proper
locations. The electrical controls are housed in a small cabinet which should be
mounted close to the press working area. The operator keypad and display are
mounted on top of the control area

INSTALLATION AND MECHANICAL SETUP OF SERVO FEED
The shipping container should contain:
1 Mechanical Servo Feed -Standard
1 Console Complete -Standard
1 Cascade Assembly -Optional (100 Series) (Standard 200-300 Series)
1 Servo Mounting Bracket -Optional
1 Guide Support Assy. -Optional
If a mounting bracket was purchased then it should be installed at this time. There are
mounting bracket prints in the back of the manual for hole location dimensions and a
bracket mounting instruction section can be found later in this section.
If a mounting bracket was not purchased then the feed should be positioned with the
centerline of the drive roller in line with the centerline of the die entrance and at the
proper pass line height to the die. Aligning the feed to the die (Parallelism) is very
important to the accuracy of the feed. Drag due to misalignment can cause short feeds
and servo faults.
If the feed is positioned as such that the material has to move unsupported from the
exit side of the feed to the die and the material being moved is allowed to droop or
buckle during a move a short feed can occur. A guide should then be built between
the feed and the die to solve this problem.
The following chart lists the servo size with the proper bolt size.
SERVO BOLT QUANTITY
Series 100 All 3/8-16 4
Series 200 4&8” Wide 3/8-16 4
12” Wide 1/2-13 4
Series 300 All 1/2-13 4
6
INSTALLATION AND MECHANICAL SETUP OF MOUNTING BRACKET
The cast mounting bracket is available for mounting the servo feed directly to the
bolster plate of the press. There are several sets of mounting holes in the bracket to
afford the setup person an efficient means of mounting the bracket. Mounting holes
are located on the top and front for securing the bracket firmly. It is very important that
the servo bracket and the servo feed be secured and not allowed to float or vibrate.
Note: It is very important that the end of the bolster plate where the servo feed is to be
mounted, be perpendicular to the top surface of the bolster plate within +-.005 to
assure the servo feed will be aligned for proper feeding.
Align the servo feed bracket with the center line of the bolster plate and transfer the
mounting holes on the top face. There are two 1/2” holes on the smaller bracket and 3
1/2” holes on the large bracket.
Once the bracket has been aligned and secured to the bolster plate, the servo feed
can now be put in place. The slotted holes in the mounting bracket allow for accurate
alignment of the servo feed in the x-y axis. There is an elevating screw to position the
servo feed to the proper tooling pass line height.
When the servo feed has been aligned and mounted to the bracket, loosen the
elevator locking screws and position the servo to match the tooling pass line height.
This is accomplished by turning the adjusting screw provided. When the servo is
correctly positioned, tighten the elevator locking screws to prevent the unit from
moving. There are 2 locking screws on the small bracket and 3 locking screws on the
large bracket.
The unit is now assembled and the next step will be to attach the electrical and air to
the servo feed unit.
7
MECHANICAL ROLL RELEASE SETUP
All Rapid-Air feeds are supplied with a manual pilot release. If the manual pilot release
is used, and we recommend this for press speeds faster than 250 SPM, then a bracket
has to be manufactured and attached to the press ram to actuate the pilot release
mechanism.
(Note: The roll release height adjustment screw should be backed off all the way to
prevent jamming when using the mechanical release.
The pilot release bracket should be made adjustable in order to set the roll release at
the proper press position. Some attention should be given to the bracket stroke length
so that the release mechanism is not jammed into the feed during the press stroke.
The 100 series pilot release actuator has a 1” stroke to full open with an additional
1.250” overtravel before bottoming out.
The series 200 and series 300 pilot release actuator has a 1” stroke to full open with an
additional 1.375” overtravel before bottoming out.
We do not offer any manufactured bracket to assist you because there are as many
combinations for stroke and clearance as there are presses manufactured today.
We do, however, ask that the bracket be designed to withstand considerable resistance
as the mechanism has to defeat or overcome the incoming air pressure or roller
pressure spring force depending on which servo unit you purchased.
ELECTRIC PILOT RELEASE
If an electric pilot release is used and the servo is a series 200 or series 300 then a
switch from the press has to be wired into the control box to control when the release
has to take place. If a series 100 was purchased then an optional pneumatic pilot
release has to be purchased.
OPTIONAL PILOT RELEASE #10900402
The optional pilot release package consists of a valve and a fitting. A switch signal
from the press has to be wired to the valve and an air line has to be connected to the
valve from the main shop air. This arrangement is seperate from the electrics supplied
by Rapid-Air
8
ELECTRICAL CABLES AND AIR LINE
230 VAC INPUT
The required input voltage to the control is 230 Vac, 3 Ph, 60 Hz. The amperage
needed is 6 amps for 752 control and 10 amps for the 753 control. If unsure of the
amperage needed, the name plate on the side of the Pacific Scientific drive will give
the number of the control or check the disconnect fuses for the correct fuse size.
460 VAC INPUT
If your plant has only 460 Vac power then a step down transformer is needed in order
to run the servo feed. If you purchased the transformer from Rapid-Air then all that is
needed is to connect and wire the 460 volt line to the enclosure. If you did not
purchase a transformer from Rapid-Air then a 3 KVA, 460/230 VAC 3PH, 60HZ step
down transformer is needed before proceeding with the electrical portion of the
installation.
The electrical control enclosure is shipped completely ready to be connected to the
mechanical feed. Connected to the bottom of the enclosure are (2) cables with keyed
screw type connectors for connection to the motor and if the series 200 or 300 was
purchased, (1 or 2) push on connectors for connection to the air valves for solenoid
actuation.
Position the electrical enclosure at a convenient location near the meachanical feed
and attach the cables. The motor cables are easily identifiable by the amount of pins in
the plugs. The solenoid cables if any can now be attached and checked for proper
location when the feed is up and running.
An air line must be connected from the shop air to the air inlet of the servo feed. The
air should be at least 80 PSI continuous and should be dry filtered and lightly lubricated
for the best operation of the servo feed. The air inlet on the servo feed is a 3/8-18 NPT
pipe tap. The minimum air line size requirement is 1/2”ID hose. - (2 CFM)
9
INTERFACING SERVO FEED WITH A PRESS
The Servo Drive unit is a slave to the press therefore it needs a command from the
press to operate in the automatic mode.
The command is in the form of a normally open contact from a limit switch, cam switch
or an electronic feed interface device that can be programmed.
The contact should be commanded or activated at 270 degrees of the press stroke or
when the tooling is clear of the material and released or turned off at around 350
degrees of the press stroke. The significance of the release position is to insure that
the feed switch is released with the press top stopped. Once the program senses a
closure of the feed input, it will command a move and will complete the move
regardless of the switch position.
The air operated pilot release also has to have a signal input to operate. The pilot
signal should be set to turn on when the point of the pilot is entering the hole. This
signal then commands air roll release to raise and release the material, letting the pin
pull the material forward into position. The release should be then commanded to turn
off letting the rollers return to a holding position for the next move.
The roll release adjustment screw is located at the entrance of the feed. The screw is
used to limit the travel of the roller during release. Adjustment may be necessary if
using air pilot release and speed is a factor. To adjust, insert material into the feed,
lower rolls, adjust screw, using 3/16 hex wrench, to full in release rolls and adjust
screw so the material is free to be pulled in by the pilot pin. The adjustment is now
complete.
(NOTE: This adjustment does limit the manual roll release travel. If this causes a
problem back off the adjustment a little.)
The schematic in the back of this manual points out the switch or contact connections
for wiring the interface. Locate the feed and pilot signal input and wire per print.
These inputs are brought down to a terminal strip for your convenience. The feed input
number is (J55-1) and the pilot input number is (J55-2).
This completes the initial setup of the servo feed to the press or other device. The
servo is now ready to run as intended.
If more complete interfacing is needed, please refer to the section (interfacing ) in this
manual for an explanation of inputs and ouputs available.
10
PRETEST FOR SERVO FEED AND PRESS WITHOUT MATERIAL
Now that your servo feed unit has been mounted and the cables have been attached,
you can proceed with testing the unit. The first step is to turn on the main disconnect
switch on the electrical enclosure. Next, at the operator’s console, pull the power onoff button to the on position. The button should illuminate to indicate that there is
power to the system.
The Pacific Scientific drive preforms an initiate sequence to check it’s internal program.
At this time the display should show the Rapid-Air screen for 5 seconds before starting
the main setup program. If you are comfortable with programming a job then continue,
if not, please refer to the “Programming Procedure” located in this manual.
Follow the programming sequence for the operators terminal to input parameters into
job storage. Your servo feed has been fully tested before it was shipped to your facility
and this procedure is merely a test to insure that all functions are still functional and the
cables are properly seated.
Once you have programmed the required parameters, select the manual mode of
operation. Check that the main air is at least 80 PSi and check that the roll pressure
gage is functional by adjusting the pressure up and down, This is accomplished by
turning the pressure adjusting knob. Open and close the feed and anti-backup rolls
electrically and or manually. Visually inspect that the rolls open and close as you press
the appropriate keys on the keypad or when using the manual levers.
Select the “inch” function (F2 on keypad) on the manual mode screen. Visually check
that the rolls rotate both forward and reverse with the corresponding key. The speed is
preset to creep the rolls at a slow speed for manual positioning of the material.
CAUTION: Do not attempt to place your fingers or any foreign material into the rolls.
Injury to the operator or damage to the servo rolls could result.
After you have verified that the rolls and air logic are operational, you can experiment
with the single cycle moves. The procedure is outlined in the programming section of
this manual.
Now, you can cycle the press and watch the rolls to verify that the signal from the
press window switch signal is functional and actuating at the proper time.
After all the checks have been made and you feel comfortable with the programming
of the servo controller, place the servo in automatic mode. Now cycle the press in
either the inch, single stroke or continous run, the servo feed should react upon the
closure of the press window and signal and simulate a feed progression of material.
11
LOADING MATERIAL INTO THE SERVO FEED
Upon the satisfactory completion of all the tests, you should be ready to load a strip of
material into the servo feed.
Step number one is to select the manual mode of operation on the operators console.
Then choose “Operate Rolls”. This will allow you to open the feed rolls and antibackup
rolls to accept the material. You could also open the rolls manually by turning the
levers mounted on the side of the servo feed. Position the leading edge of the
material near the center of the entry rolls and adjust the edge guides on the cascade
rolls to the proper width setting. Open the feed rolls and anti-backup rolls. Hand feed
the material into the servo unit until it protrudes out of the feed rolls and starts into the
guide on the press. Close the anti-backup rolls to capture the material, then close the
feed rolls.
Check the roller force pressure to be sure that there is enough pressure to prevent
slippage but not too much to induce camber into the material. The pressure setting is
the amount of force necessary to move the material into the press at the speed and
feed programmed. You may find it necessary to readjust the force as you finalize the
setup procedure. The amount of force needed will vary depending on the width and
type of material being fed. Make a note of the final setting to aid in the setup of the
servo feed the next time the same material is run.
You are now ready to begin testing the complete system under power. To check the
progression, cycle the press in the single cycle mode with the servo feed in the
automatic mode. If the progression is correct, no further adjustments are necessary. If
the progression is either short or long, go to the troubleshooting chart and perform the
sequences described there for inaccurate feeding, once the feed progression has been
accuratelly set and the repeatability is satisfactory, you are ready for full automatic
mode.

SERVO INTERFACING EXPLANATION
A. TAUT STOCK INPUT (J55-3)
This is a normally open contact from a switch or device that monitors the loop of
material prior to the servo feed. When the material reaches a point that it trips the
switch, a taut stock has been reached. This input, when received, immediately drops
the automatic which stops the feed in progress. The material should be repositioned in
the die before restarting the automtaic sequence.
This input also could be used as a “No Stock” switch that would monitor whether or not
there is material available to feed.
B. ANTI-BACKUP INPUT (J55-4)
Whether the anti-backup rolls where purchased with the unit or came on the unit
standard, they can be activated to raise in the automatic cycle. The anti-backup rolls,
by design, keep the material from sliding back during the pilot operation. They can
become a hinderance if the material tends to walk to one side or the other during the
feed cycle.
The anti-backup switch was designed in for this reason. If this problem is being
experienced then a switch or a cam switch with a normally open contact can be wired in
from the press. Usually this switch is activated when the press is at 180 degrees or
when the die is closed to be sure that the material is being held in postion. The rolls will
raise for the amount of degrees that the switch is activated, letting the material
reposition itself in line with the die. It is crucial that this switch is not activated for too
long a time as when the die releases the material, the material will slide back which will
cause a misfeed. This feature has to be used in conjunction with the main rolls being
raised or it will not give the desired results as one of the rolls will be holding the
material from moving.
C. ENABLE INPUT (J53-4)
The enable input is shipped from the factory, jumpered, so that the Pac-Sci unit is
ready to work after the initialization procedure is complete.
If it is desired that the servo controls are not functional until other equipment or safety
source is activated before this unit can function then a normally open contact can be
interfaced to this input. If at any time during the feed cycle the input changes state then
the feed will stop at this position. If feeding stock, the reference will be lost and the
stock will have to be manually repositioned to the correct location. The automatic cycle
will be dropped and have to be restarted.
13
D. GAG OUPUTS (J53-6 to J53-9) & (J54-2 to J54-5)
This output must be tied to a solid state relay to interface to the outside world. The
solid state relay must have a D.C. coil and should have a rating of 3-30 VDC. The
Rapid-Air #69100165 is recommended for this application. This output is high
whenever the enabled input is activated. If using DC coils then 3-30 VDC sink, max
100 MA, per output.
E. END OF FEED OUTPUT (J54-6)
This output must be tied to a solid state relay to interface to the outside world. The
solid state relay must have a D.C. coil and should have a rating of 3-30 VDC. The
Rapid-Air #69100165 is recommended for this application. This output goes high at the
end of every feed and stays high for programmed duration before going low.
F. AUTOMATIC OUTPUT (J54-7)
This output must be tied to a solid state relay to interface to the outside world. The
solid state relay must have a D.C. coil and should have a rating of 3-30 VDC. The
Rapid-Air #69100165 is recommended for this application. This output goes low
whenever automatic is selected on the program panel. Any faults will cause the
automatic ouput to go high.
G. KEYPAD AND DISPLAY INTERFACE (RS 232 PORT)
The keypad/display is the interface between the operator and the resident program.
The Pacific Scientific drive is purchased with a great many capabilities, none of which
can be used unless a program is written to utilize these capabilities. Rapid-Air put a
great deal of time making a program that is user friendly and yet gets the job done
efficiently. We took all the questions and constructive criticism and came up with a
program that would cover all the applications, yet be easy to interface and program by
a customer.
H. GAG CHECK INPUTS (J55-7&8) & (J56-1 to 6)
All inputs must be tied to only dry contacts.
J56-8 hook to a switch that is mounted on the press. When this switch is tripped, the
program will check that the inputs and outputs match only if the J56-7 input is shorted.
J56-7 short this input to wire #8 when inputs are to be used to verify that output devices
have functioned.
If an operator reads the programming procedure in this manual and then reads the
screen parameters listed as they are displayed and acts on them by inputting data as
needed, the servo can be up and running in a very short time.
1. Select a job number.
2. Input or review parameter for that job number.
3. Thread up material in manual mode.
4. If properly interfaced, go into automatic mode.

OPERATOR INPUT TERMINAL - PROGRAMMING PROCEDURE-STANDARD
SOFTWARE
The intent of this section is to familiarize the operator with the program flow and what
to expect with every keypress. Each screen on the display will be reviewed with
special comments to help clarify what is being asked on the screen. The program flow
is broken down into 5 sections with the main menu being the home postion. Reviewing
the flow chart in the back of this manual will help in understanding the sections.
SECTION1 —- F1=JOB ENTRY
SECTION2 —- F2=MANUAL MODE
SECTION3 —- F3=AUTOMATIC
SECTION4 —-F4=REVIEW JOB PARAMETERS
SECTION 5 —-RAMP=ADJUST ACCELLERATION AND DECELLERATION
The first screen to be displayed on the operator terminal will look like this

F3=AUTOMATIC CYCLE
F4=REVIEW JOB PROGRAM
SELECT F1=JOB #
The first step in programming the servo feed is to select a job number which will be
used to store the parameters the operator inputs or recall the parameters which have
been previously loaded into the servo controller program. When the operator selects
F1 on the keypad, the screen will change to:
JOB SELECTION MENU
ENTER JOB NUMBER=XX
PRESS F4 KEY ONCE
CORRECT # IS ENTERED
The operator must enter a 2 digit number before proceeding to any other function. If
the job number the operator has entered has been previously stored in memory, or
entering a new job, the following display will appear:
JOB NUMBER-01 LOADED
F1=PROGRAM NEW VALUES
F4= DON’T ALTER VALUES

The job number screen displays (2) choices for the operator. In the first choice,
F1=Program new values, the operator can enter or change the number of sequences,
repeats per sequence, pilots, feed length, strokes per minute that the press is running
and feed arc angle. (Free travel of the press in which the feed can move material
without a problem) this then calculates the optimum speed of the material movement.
The second choice, F4= Don’t alter values that are programmed, puts the job number
entered in memory for running at this time. If F1 was selected the following display
would appear.
JOB NUMB=XX ENTER IN
NUMB OF SEQUENCES=XX
PRESS F4 KEY ONCE

When the automatic screen is displayed, all keys except the F4 key are inactive. Every
time the press cycles and trips the feed switch, the feed will cycle once per the
parameters displayed on the screen. If the feed encounters excessive materail drag
while feeding or the material being moved encounters a restriction taht stops the
material forward movement then a servo fault can occur. If this happens then the
following screen is displayed.
A DRIVE FAULT HAS
OCCURED PLEASE CHECK
THE CONTROLS DISPLAY
FOR TYPE OF FAULT
If this screen is displayed then the control cabinet has to be opened and the Pac-Sci
drive has to be checked. To reset the fault, the master on-off switch has to be cycled
which will reset the controller. The material path should be checked for obstruction
and parrallelism to the die. If all this seems to be satisfactory and another fault occurs
the factory should be consulted.

DRIVE ROLL PARALLELISM ADJUSTMENT
Every servo feed has an eccentric adjustment screw to adjust the upper roller to be in
parallel to the lower roller. The maximum adjustment is .008” on the eccentric.
The adjustment screw is located behind the belt cover and is held fast by a 10-32
socket head cap screw. The acutal adjustment screw is a slotted eccentric pin which is
turned clockwise or counter-clockwise to raise or lower one end of the upper roll.
The parallel adjustment is factory set when the unit is manufactured but if material
tracking seems to be a problem then this could be a way of solving the problem. To
test if the rolls need adjustment, do the following.
1. Remove the front and rear roll covers.
2. Raise the anti-backup rolls (if any) and close main rolls.
3. Shine a light from the rear of the feed toward the main rollers.
4. Inspect from the main rolls side to see if the rollers are parallel. If they are then the
material could be the cause of the material walking. If they are not parallel then an
adjustmet has to be made.
5. To make the adjustment:
a. Remove manual roll release arm by removing roll pin.
b. Remove belt cover.
c. Locate eccentric screw and loosen 10-32 screw.
d. Turn slotted eccentric screw while viewing rolls until the rolls are parallel.
For a more accurate adjustment use a feeler gage to check the parallelism.
e. Tighten 10-32 screw and reassemble parts, then retry running material.
This completes the eccentric adjustment write-up, if there are further questions,
please call the factory.

MOTOR SERVICE
The servo motor is flanged mounted and secured with four socket head cap screws.
The motor removal has to be done in a sequence as described below.
1. The manual roll release handle has to be removed. The inner roll pin holds the
handle to the shaft. Once this is removed the handle should slide off the shaft.
2. The belt guard has to be removed. It is fastened with four 1/4-20 socket head cap
screws.
3. Remove the belt tension and then the belt sheave has to be removed. To
accomplish this, rotate the sheave until the large end of the tapered shaft is to the
bottom. A support then has to be put under the center of the sheave to stop any
deflection of the motor shaft when driving out the tapered pin that holds the sheave to
the motor shaft. Drive out the pin and remove the sheave and then the motor.
4. Install new motor and reassemble in reverse order of the previous instructions.
Note: Use the sheave support when reassembling the tapered pin.
5. When reinstalling the belt, the tension on the belt should be 1/64” deflection per inch
distance between the center lines of the pulleys using 1.5 to 2 lbs. force to cause the
deflection.
MANIFOLD ASSEMBLY
The manifold assembly was designed to give the customer easy access to the
components. The valve for the electric roll clamp and if supplied, the anti-backup valve
are mounted on the side of the feed. The air regulator and pressure gauge is mounted
on the input side of the feed. All can be easily replaced if needed.
ROLLER AND GEAR BOX ASSEMBLY
At this stage of disassembly, all field maintenance components are exposed and easily
accessible. No further field service should be necessary on the roller and gear box
assembly unless the gear train is suspected of a malfunction. The drive rolls should be
checked for erroneous wear pattern while they are exposed and cleaned before
reassembly.

REASSEMBLY OF UNIT
Prior to assembly, attention must be given to three points of contact that require an
application of Moly-Cote, Lubriplate or other suitable heavy grease.
The three points are:
1. The antibackup piston which is located at the feed entrance.
2. The main roll piston and the spiral pins in the main roller tie plate which can be seen
by viewing straight down through the center of the feed at approximately half way from
the inlet to the exit roller. The piston is positioned horizontally at the base of the feed
and approximately in the center of the feed if viewing from the gear box to the belt
cover.
3. The mechanical roll release shaft located at the exit side of the feed. Three screws
have to be removed and then the keeper plate can be removed. The inner shaft should
be thoroughly greased to prevent sticking.
Do not apply excessive grease as it may fall onto the drive rollers and cause
misfeeding due to material slippage. All bearings are sealed and need no additional
lubrication.
LUBRICATION
The gear box oil must be kept up to sight gauge level and changed after every 2000
hours of use. Recommended oil is Mobil #SHC630 or equivalent. The oil reservoir
capacity is 3.5 oz. The oil can be drained by removal of the drain plug located near
the base of the gear housing cover, just below the sight gauge. The oil reservoir is
filled through the pipe thread port occupied by the air breather plug near the upper
edge of the gear housing cover.
NOTE: THE ORIGINAL BREAK-IN OIL IN THE GEAR BOX SHOULD BE CHANGED
AFTER 100 HOURS OF CYCLE TIME AND EXAMINED FOR CHIPS OR FOREIGN
MATTER. REPLACE THE GEAR BOX OIL PER INSTRUCTIONS.
The anti-backup rollers have been lubricated at the factory and should need no further
attention. If they are found to slip in the reverse direction, consult the factory for further
assistance.
PINCH ROLL & ANTI-BACK UP ACTUATING PISTONS
Periodically grease with lubriplate or equivalent grease to anti-backup & pinch roll
actuating piston nose where it contacts the pressure plate.
