OPERATION
1) Open the storage tank cover.
2) Set the multi-port valves to fill the storage tank from the drum as shown. To reduce fill time, turn the
air regulator adjustment knob clockwise increasing adhesive flow. (This operation need only be repeated
when the level of the adhesive in the storage tank is low and is being replenished. Keep the 55 gallon
adhesive drum for later use as a water bath during clean-up.) See Fig. B.
3) Remove the storage tank cover. Stir the adhesive in the storage tank with a paddle or long wooden
handle after removing the cover.
4) Set the valves so that the adhesive circulates to the trough from the storage tank as shown. Turn the
air regulator knob counter clockwise (decreasing adhesive flow). Allow the adhesive to slowly spillover the
spillgate into the storage tank during operation.
5) To regulate the amount of adhesive applied to the liner, turn off the power and lift the safety guard on
the material entry side of the Roto Bonder. Raise the feed table and allow the table to drop perpen-
dicular toward the floor. Turn the Selector Knob Assembly to the “Clean” position. With the power on,
look into the machine. Do not put your hands into the GBAC. Turn the Metering Wheel (clockwise to
decrease-counter clockwise to increase) to adjust the amount of adhesive that coats the adhesive roll.
For maximum efficiency, the adhesive roll should be coated with a thin even coat of adhesive. With power
off, replace the feed table and return it to its proper position. See Fig. C and D.
6) Switch the power on.
7) Adjust the GBAC for liner thickness by moving the Selector Knob Assembly [clockwise to increase (thicker
liner), counter clockwise to decrease (thinner liner)] to adjust the roll clearances. See Fig C.
8) Feed the pre-cut fiberglass liner material into the Roto Bonder. Coated material is automatically carried
through to the exit fingers.

CLEAN-UP
1) With power on, turn the metering wheel clockwise until the metering blade is against the adhesive roll.
See Fig. D.
2) Set the multi-port valves so that the adhesive empties from the trough to the storage tank. When the
trough is empty, back the metering blade away from the adhesive roll. Disconnect the air and turn off
the power. See Fig. A and D.
3) With power off, lift the safety guards on the feed side of machine, and remove the metering bar and
blade. Sponge clean the metering bar and blade, and reinstall it. Cover the adhesive in the storage tank
with a thin film of water, and cover the tank.
4) Fill the empty 55 gallon adhesive drum with water for use as a water bath.
5) Turn the air on and place valves 1 and 4 to the up position, and valves 2 and 3 to the down position. Al-
low water to circulate (drum to drum) for at least (2) minutes. Proceed to Step 6. See Fig. A.
6) Turn the air on and adjust the valves to fill the trough with water from the 55 gallon drum. Then readjust the
valves to circulate the water from the trough to the trough (in-out), for at least five minutes. Disconnect
the air. Allow the water to remain in the stainless steel trough while the machine is not operating . See Fig. A
7) Rotate the Selector Knob Assembly into the “Clean” position. This will allow the adhesive roll to rotate
with the guard up. The adhesive roll will be rendered inoperative when the safety guard is lifted if the
adjustment lever is not in the clean position. See Fig. C and D.
8) With the power on, lift the safety guard. Clean the adhesive roll while it rotates with a long handled
brush from the feed side of the machine. Do not put your hands in the GBAC. When the roll is clean, be
sure you reposition the adjustment lever. Do not attempt to clean the adhesive roll unless the adjust-
ment lever is in the clean position. Do not render safety micro-switches inoperative. See Fig. C and D.
9) Turn the power off. (The metering blade will have to be readjusted when next used.)
10)Remove the exit rack and sponge it clean. Replace the exit rack.

EXTENDED CLEAN-UP
NOTE: If the machine is to be idle for several days there are additional clean-up procedures which must
be followed.
1) With power off remove the exit rack and metering bar. With a long handled brush wipe down the trough.
At this time the trough should still contain water.
2) Cover the 55 gallon drum of water. Turn the air on and empty the adhesive from the storage tank to the
55 gallon drum. Cover the adhesive in the 55 gallon drum with a thin coat of water and cap the drum.
See Fig. A
3) Set the multi-port valves so that the water empties from the trough to the storage tank. See Fig. A and B
4) With the power off remove the feed table and tank cover. Set the multi-port valves to fill the storage tank
from a convenient water bath, and with a long handled brush wipe the side of the storage tank. See Fig. A
5) Set the multi-port valves so that the water empties from the storage tank to a convenient water con-
tainer. See Fig. A
6) Disconnect the air and power. Wipe the adhesive roll dry and return the feed table, exit rack, and metering
bar to their proper position.
MAINTENANCE
1) Periodically grease the end bearings on the adhesive roll as well as the metering bar gearing.
2) The metering bar wiper blade can be removed and rotated 180° (end over end) as the blade shows wear.
AIR SUPPLY UNIT
1) To provide uninterrupted service, the air regulator assembly must be kept clean. Turn the drain valve clock-
wise to drain off any filter bowl accumulation before it becomes full. A visible coating of dirt or condensate
on the filter element or erratic operation indicates cleaning is necessary. Wash the filter element and
the regulator, in denatured alcohol and blow them out with compressed air. Clean the Filter Bowl With
Household Soap Only.
2) Check for leaks in all air hoses.
3) Check and adjust the air pressure to 80 psi minimum. When reducing regulator pressure, pull the knob
upward and turn the knob counter-clockwise. Cycle the machine before reading the gauge. To increase air
pressure repeat the procedure turning the knob clockwise.

It is necessary to use a voltmeter and an ohmmeter
to perform the simple servicing procedures.
MEASURING RESISTANCE (OHMMETER)
1) Disconnect the power supply.
2) Set the ohmmeter at x1000
scale and keep it there for
all resistance reading.
3) Touch the two probes
together and “zero” the
ohmmeter.
ELECTRICAL SERVICING
If the power switch is on and the rolls do not turn,
follow the procedure outlined below.
1) Check the power supply for 110 volts.
2) CAUTION: This troubleshooting step requires
bypassing the safety switches. Be extremely
careful to keep hands and clothing away from
any moving parts or electrical connections.
Remove the top cover. Remove the screws
retaining the inner panel with the guard inter-
lock attached. Let this panel hang. Depress
each microswitch placing a shim between the
microswitch button and the flange the button
protrudes through. With power on, read voltage
across 1 and 2 on terminal strip.
If the voltmeter reads: 110 volts, proceed to
Step 3.
If the voltmeter reads: “0” V: the problem is
either broken wires from the power supply to the
power switch or a defective power switch.
3) With the power on, read the voltage across 1
and 3 on the terminal strip.
If the voltmeter reads: 110 volts, proceed to
Step 4.
If the voltmeter reads: “0” V: the problem is
Follow the instructions below for reading resis-
tance and voltage.
MEASURING AC VOLTAGES
(VOLTMETER)
1) Set the voltmeter at
the nearest scale above
(never below) the voltage
you wish to read.

either a faulty or misadjusted guard interlock
or a broken wire from the terminal strip to the
guard interlock. (Trace the wires from the
terminal strip to the guard interlock.)
4) With the power on, read the voltage across 1
and 4 on the terminal strip.
If the voltmeter reads: 110 volts, proceed to
Step 5.
If the voltmeter reads: “0” V: the problem is
either a faulty or misadjusted guard interlock or
a broken wire from terminal strip to the guard in-
terlock. (Trace the wires to the guard interlock.)
5) Replace the panel and the cover. Remove the
motor side cover. With the power on, check
whether the motor is turning or not. If the motor
does turn, check that the keys and set screws
in the sprocket are in position and tight. If the
motor does not turn, check that the reducer is
not bound up - replace the motor.

CIRCULATION SYSTEM SERVICING
The air is on but the adhesive is not circulating through the plumbing.
NOTE: Never force a valve handle. If a valve handle sticks, remove the valve and soak it in warm water.
1) Check the valve setting against the function chart to insure that the valves are set properly. If the valves
are set properly, proceed to Step 2.
2) Check that number 2 valve is either in the up or down position. The circulation system will not work unless
number 2 valve is in either position. Then proceed to Step 3.
3)
Check that the air-regulator unit is functioning according to the maintenance section of the Operating Instruc-
tions.
4) Disconnect the air line that leads from the regulator to the pump. With the air line disconnected, check
the air supply. If there is no air leading into the pump, proceed to Step 5. If there proves to be a good air
supply, reconnect the air line and proceed to Step 6.
5) Disconnect the air line leading to the air regulator and check the air supply. If there is a good air supply to the regu-
lator, replace the regulator. If there is no air supply to the regulator, the problem is independent of the GBAC.
6) Fill a bucket with warm water. Place the GBAC input hose in the warm water and set the valves to fill the
trough from the drum. Activate the pump. If the water begins to pump into the trough, deactivate the
pump immediately and proceed to Step 8. If no water pumps to the trough, proceed to Step 7.
7) Fill a bucket with warm water. Place the GBAC input hose in the warm water and set the valves to fill the storage
tank from the drum, Activate the pump with air. If the water begins to pump into the storage tank, deactivate
the pump immediately and proceed to Step 8. If the water does not circulate, proceed to Step 9.
8) Remove the bucket of warm water and set the multi-port valves to circulate the adhesive from the drum
to the trough. If the adhesive will not circulate, proceed to Step 9.
9) Set the multi-port valves so that adhesive circulates from the storage tank to the trough. Activate the
pump and observe whether adhesive is flowing into the trough. If there is an adhesive flow, proceed to
Step 12. If there is no adhesive flow, proceed to Step 10.
10) Disassemble the plastic union located beneath valve 2. Set the multi-port valves so that glue circulates
from the storage tank to the trough. If adhesive is pumped from the union, disconnect the air and replace
the valve assembly 1 and 2.
Note: It is important that all surfaces on the valves and the unions be free of glue residue before reassem-
bly.
If the glue is not pumped out from the union, disconnect the air, reassemble the union and proceed to Step
11 .
11) Set the multi-port valves so that the adhesive empties from the tank to the drum. Activate the pump. If the
adhesive exits the machine from the out port, replace valves number 3 and 4. (Order an assembly.) Close
valve number 5 if supplied, before disassembling valve number 3 and number 4. After replacing valve number
3 and number 4, open valve number 5. If the adhesive is not pumped out the exhaust port, proceed to Step
12.
12) Set the multi-port valves so that the trough is filled from the drum. Activate the pump. If adhesive is
pumped into the trough, replace valve assembly number 1 and number 2. If adhesive does not pump into
the trough, proceed to the pump service manual.
