UNPACKING, SET-UP & PRE-START CHECKS
60089-05 Page 6
UNPACKING
 Check for shipping damage. File claims with the shipper
for any apparent damage.
 Remove any plugs and caps from both hoses and attach
hoses and tubing to main system as indicated (if hoses
are shipped detached).
 Check for loose bolts, fittings, etc. which may have
loosened during shipping.
SET-UP & PRE-START CHECKS
 Connect motor controller to power supply (120VAC). Use
a ground fault interrupter (not supplied). Using a GFI
Plug will help protect the motor controller and greatly
improve service life.
 If using an extension cord, it must be no longer than 100
feet, 14 gauge. Longer and/or smaller gauge supply may
starve the controller, causing erratic pump performance
and may cause the controller fuse to blow.
 Do a preliminary check of system before filling material
containers. Actuate handle trigger & release signal to
stop.
 Filling containers with material: Make sure respective
materials are poured into designated containers. Fill at
least ½ full & place lid on each container immediately
after filling. Label both containers to assure correct filling.
When filling, place lid on tank not being filled.
 Filling hoses and applicator: Actuate system and slowly
run until allowing materials to flow through both hoses to
the applicator. IF MIXER NOZZLE HAS BEEN
ATTACHED, REMOVE TO AVOID MATERIAL CROSS-
OVER.
 HOSE FILLING PRECAUTION: Any high point in hose
can hold air and allow an air gap. Slope hose on a
gradual upward slope away from system to applicator
while filling. The dispense valve should also slope
upward in a similar manner until materials flow smoothly
out of both ports of the dispense manifold. In almost all
cases, “A” and “B” materials behave differently and fill at
different rates. Let earlier appearing material flow into
waste container until other material is also flowing freely.
 Establish proper flow of both materials at dispense
manifold WITHOUT THE MIXER ATTACHED. Hold the
top into a waste container and actuate the system.
Observe flow of both materials from the round ports and
continue to run the system until a positive, air free flow is
achieved. Wipe clean and apply compatible lubricant to
the tip and the treaded area to permit easy removal later.
 Attach proper mixer to applicator tip and tighten mixer
nut.
 Purge at least 3 mixer volumes of material and discard
static mixer.
The system is now ready for dispensing meter/mixed
materials!
OTHER TIPS & TIDBITS
 Keep this instruction manual
 Never permit either material tank to get below
approximately 1/3 full.
 A common problem is cross-over (one material crossing
over into the other material’s manifold and/or hose).
Damage and cost from cross over can be avoided by
carefully following instructions.
 Air can be trapped in hoses during filling of an empty
system. To avoid trapping air, arrange the hoses to
obtain a continuous gradual upward slope of the hoses
from the pump outlet to the applicator while the system is
pumping at low speed. Point the dispense assembly
upward to let the material push the air out.
 Two zerks are provided on each side of the dispense
manifold, where the static mixer is attached to the
applicator. These are provided so that the operator can
remove the mixer and fill the ports of the manifold with a
compatible lubricant. This helps prevent problems with
material hardening in the manifold, and should be done
when the unit is left unused for any period of time.
 The gerotor pumps are lubricated in two places. Both
should be lubed daily. When the zerk on the top of the
pump is filled, the bleed valve at the bottom of the pump
must be opened. Lubrication is complete when fresh
lubricant is pushed out from the bleed valve.
 Low material temperature raises the viscosity inside the
system, greatly increasing the work required to pump. If
system is to be used in a cold temperature situation,
material & system should be kept as close to or above
room temperature as possible. Any heating of material
must be regulated no higher than maximum temperature
recommended by material manufacturer.

DAILY OPERATION/DAILY MAINTENANCE/TROUBLESHOOTING
60089-05 Page 7
START-UP
 Check level of materials in containers, making sure level
is always over ¼ filled.
 Clean off applicator dispense head with plastic mixer
nozzle removed
 Verify smooth, air-free flow of both materials by
dispensing material into waste container. Check for two
smooth, consistent streams of material.
 Wipe head clean and coat dispense head with compatible
lubricant.
 Place new plastic mixer nozzle on dispense head with
retaining nut.
 Dispense approximately 2 mixer volumes of material into
waste container.
 Make 2 or 3 test samples to verify performance.
SHUT-DOWN
 Remove static mixer nozzle.
 Trigger applicator to relieve any pressure in lines or
system. Materials may ooze out of applicator.
 Turn off or disconnect motor controller.
 Fill dispense manifold with compatible lubricant. Fill each
zerk until material inside dispense manifold is replaced
with compatible lubricant.
 Lubricate each pump:
o Open bleed valve at bottom of pump.
o Grease zerk at top of pump until material coming out of
bleed port is clean, fresh lubricant.
o Close bleed valve & verify tanks are over 1/3 full.
PERIODIC MAINTENANCE
 Remove and clean any material residue or film with
compatible solvent (damp pad only – do not pour
solvent)
 Lubricate with compatible lubricant.
 If leakage appears at shaft, replace seals.
**Use caution when disassembling the Gerotor pump
making sure not to gouge or mar any of the internal
surfaces of the pump**
DISPENSE MANIFOLD MAINTENANCE
 Clean threads & ports of dispense manifold
 Remove & soak manifold in compatible solvent, if
necessary
 Replace o-rings, packings & seals, if necessary
RATIO CHECK
 Remove retainer cap and/or mixer nozzle
 Trigger applicator; two separate beads of material will
appear; compare for correct volume
 Replace o-rings, packings & seals, if necessary
TROUBLESHOOTING
VERY IMPORTANT: As soon as a problem is noticed,
immediately remove disposable mixer nozzle and try
dispensing material. This may prevent or purge material
crossover if it has not already hardened.
After static mixer is removed, THEN check the following:
 Is the dispense manifold plugged? (Material set up)
 Is there sufficient material in the tanks?
 Is the machine dispensing on ratio?
If ratio is not correct:
 Check if air is entrapped in the pumps or hoses
 Check if the drive chain is loose or worn
 Check if one or both of the pump sprockets are frozen
(Can the sprockets be rotated by hand?)

RATIO CHECK PROCEDURE
60089-05 Page 8
The following is the list of items to check if the equipment is not dispensing the correct ratio. Please note that some items
included in this procedure are not included with all supplied equipment. Please use all safety devices such as but not limited to
gloves and eye protection. When working with solvents do so in a well-ventilated area free of combustible items. Take every
effort not to mar or damage any surfaces that come in contact with materials.
If you suspect the ratio is incorrect and the dispense valve is in good condition, proceed as follows:
 Remove retainer cap and/or mixer nozzle.
 Trigger applicator; two separate beads of material will appear. Dispense each bead into separate cups; compare for correct
volume.
o If ratio is incorrect with mixer off, proceed to Step 3
o If ratio is correct with mixer off, perform additional test to verify results. If ratio is correct again with mixer off, the most
common cause is the metering pumps are worn & need replacement or refurbishing. Contact AST if this occurs.
 If volume is off from Step 2, remove hoses from dispense valve, trigger applicator & dispense each material into separate
cups. Compare volume of material dispensed out of material hoses.
o If ratio is correct, the problem is occurring in the dispense valve. Clean and/or replace seals,
O-rings & packings, if necessary.
o If ratio is incorrect, proceed to Step 4.
 If volume is off from Step 3, remove hoses at the outlet assembly. Trigger applicator and dispense each material into
separate cups. Compare volume of material dispensed out of outlet assembly.
o If ratio is correct, the problem is occurring in the material hoses. Clean and/or replace hoses.
o If ratio is incorrect, proceed to Step 5.
 If volume is still off from Step 4, disassemble & clean pumps. Replace seals & O-rings if necessary.
Other items of note:
 Verify that the air inlet to the tank is in good condition. The air goes into the tank through the 90 degree elbow.
 Check for blockages on the inlet side of the pump with the reduced output. The round inlet block will have to be taken off
the back of the pump. Then, inspect the piping leading from the tank to the inlet block. If a blockage is found, it may not be
necessary to go any farther.
 Clean and rebuild the pump. Check that the inner and outer gears are tight against each other. [Note: be careful not to
damage the inner pump parts when disassembling or cleaning. Replacement parts for the gerotors are available only as a
complete pump!] *Remove all crystallized or partially hardened material from all surfaces that contact the material.
 Check the pump outlet fitting. (The elbow fitting between the pumps and the hoses) for blockages.
**NOTE: Any material that is left in the machine that is partially or completely hardened, or foreign objects, will
eventually cause a problem somewhere and should never be left in the pump**
