heater is below the temperature setting of the
thermostat. Turn the thermostat up (clockwise)
to check the operation of the heater and then
reset to the desired setting. If this does not
solve the problem, continue to Step b.
Problems
Try the recommended solutions in the order given for
each problem to avoid unnecessary repairs. Also,
determine that all circuit breakers, switches, and
controls are properly set and wiring is correct before
assuming there is a problem.
b. Thermal Limit Switch. When moving the unit, it
is possible that the thermal limit switch may trip
in transit. If this happens, reset the limit switch
and monitor the operation of the heater to
ensure the switch has not tripped as a result of
a heater malfunction.

3. Remove the thermostat housing by removing the
two mounting screws and carefully pulling the
housing away from the heater.
g. Switch on the electrical power and monitor the
operation of the primary heater to ensure it is
functioning properly.
4. Push in the red reset button on the switch.
The design of the primary heater allows it to
maximize the heat transfer from the power
available. However, under certain conditions,
reducing the flow rate is necessary when the
heater is not available to reach the required
temperature.
5. If the Thermal Limit Switch does not feel as though it
reset, then disconnect one lead from the Thermal
Limit Switch and read continuity across the switch
with an ohmmeter. If there is no continuity, the
switch is defective and must be replaced.
6. If this does not solve the problem, replace the
thermostat.
7. Move the thermostat housing back into place and
install the two mounting screws.
8. Switch on the electrical power and monitor the
operation of the primary heater to ensure it is
functioning properly.
9. Heating Rods - The primary heater contains four
1250-watt (38.7 ohms each) heating rods wired in
parallel.
To check that all rods are operational, proceed as
follows:
a. Turn OFF all switches and lock out incoming
power at the source.
b. Remove the thermostat housing by removing
the two mounting screws and carefully pulling
the housing away from the heater.
c. Remove the heating rod wire nuts. Separate the
heating rod leads from the wire harness and
read the resistance across the four heating rods
with an ohmmeter. The combined resistance
should be 9.6 ohms. A higher resistance
indicates that at least one of the rods is not
working. If this is the case, proceed to Step d.
d. Disconnect the heating rods and measure the
resistance of each rod. Each rod should
measure 38.7 ohms.
e. Reconnect the heating rods and recheck the
resistance.
f. Move the thermostat housing back into place
and install the two mounting screws.

gauges on the unit. Focus on the pressure gauge
corresponding to the missing chemical.
After determining the missing or under-proportioned
material, observe the chemical pressure gauges on
the problem side of the unit to see if the malfunction
is due to a restriction at the gun or a lack of material
produced by the pump. To prevent misinterpretation,
focus on the pressure gauge corresponding to the
missing chemical.
Problems
Try the recommended solutions in the order given for
each problem to avoid unnecessary repairs. Also,
determine that all circuit breakers, switches, and
controls are properly set and wiring is correct before
assuming there is a problem.
For example: Assume that the R-component is not
reaching the mixing chamber. Spray off target and
note the resin pressure gauge; if the resin gauge is
considerably higher than the isocyanate gauge, the
problem is within the gun. Refer to the gun manual
to resolve the problem. If the resin gauge is
considerably lower than the isocyanate gauge, see
Solution 3.
Problem
Solution
Proportioning pump does not hold pressure
when installed.

Pressure imbalance between pumps.
Cavitation in the proportioning pump.
Pump movement is erratic.

3. Cavitation - Formation of a partial vacuum or void
created within the pump cylinder during the fill
stroke. It is actually a “short fill”, since the fill
chamber is not completely full of chemical when the
pump reverses to start the discharge stroke.
Cavitation occurs when the proportioning pump
demands a greater volume of material during its fill
stroke than the supply system can deliver.
Failure of pump to reverse.

Solutions
1. Leaking Ball Check Valve - Determine which inlet
ball check valve or piston ball check valve is leaking.
If the pump (A or R) is losing pressure on the
The most common causes of cavitation are as
follows:
upstroke, check the piston ball check valve of the
respective pump. If the pump is losing pressure on
the downstroke, check the inlet ball check valve of
the respective pump. To repair, see manual 309577.
a. The transfer pump cannot handle the supply
requirement or is malfunctioning. The Graco-
Gusmer 2:1 transfer pump is recommended for
use with the unit. Also recommended is a
minimum of 3/4 in. diameter hose, as short as
possible.
2. Pressure/Chemical Imbalance - To troubleshoot
this problem, first determine the following two
points:
First - Which chemical did not exit the mixing
chamber?
b. The chemical is too viscous to pump properly.
Consult your chemical supplier for the
recommended material temperature required to
maintain a viscosity of 250 to 1500 centipose.
Determine the first point by checking the color of the
material exiting the gun. Since two-component foam
systems are usually a combination of light and dark
material, the missing or under-proportioned material
can be readily determined in most cases.
c. Inlet strainer screen is restricted. Service as
required.
Second - Why did the chemical fail to get there?
d. An inlet ball check and/or seat o-ring that does
not properly seal will permit some of the
The second point is due to a restriction in the gun or
because the proportioning pump did not function
properly in pumping its designed volume. This is
determined by checking the chemical pressure
proportioned material to flow back towards the
supply drum. When this happens, the
proportioning pump will not pump the proper
volume of material during the discharge stroke

Troubleshooting
and an off-ratio condition will result. This
malfunction will appear almost identical to
cavitation, but somewhat less severe.
Solutions
1. Hose Length - The hose heat system of the
Predator is designed to maintain the chemical
temperature developed by the primary heaters with
up to 310 feet of hose. (Hose lengths greater than
this require the use of an auxiliary hose heat
system. Call Graco-Gusmer for details). In addition,
if ambient temperature is too cold, the hose circuit
may not have enough power to maintain the
chemical temperature.
4. Pilot Valves - Check each valve for proper
operation. If either valve is defective or damaged,
replace both valves.
5. Damaged Piston Packing - Check piston packing
set for mars or scoring. Replace piston packing set if
damaged.
2. Hose Heater Power Control - Ensure that the
power control is adjusted until the ammeter reads
15 amps (do not exceed 15 amps).
6. Air Motor Assembly - Check air motor cylinder and
lubricate if necessary. Also, check o-rings and seals
for wear and/or damage. Replace if necessary.
3. Hose Heat Fuse - With the main power OFF and
locked out at the source, remove the fuse and check
it for continuity or simply replace it with a new one.
Hose Heat System
Replace the fuse with one of the same rating. A substi-
tute may damage the equipment and would create a
potential source of injury to the operator.
Problems
To avoid unnecessary repairs, try the recommended
solutions in the order given for each problem. Before
assuming there is a problem, determine that all circuit
breakers, switches, and controls are properly set.
4. Hose Heating Element - With the hose heat circuit
breaker OFF, check to see that the Power-Lock
connectors on the hoses and all electrical
connections between the hoses and unit are tight. If
these connections are secure and hose heat is not
present, perform a systematic search for the
electrical fault. To search for the electrical fault,
proceed as follows:

blows.
a. With the hose heat circuit breaker OFF and the
power control turned fully counterclockwise,
starting at the gun whip, unplug the Power-Lock
connectors and plug the hose troubleshooting
jumper plug (included with accessory package)
into the last “upstream” segment of hose.
Hose temperature not maintained during
flow.

Hose or hoses adjacent to the unit are warm
- hoses downstream are cold.
b. Turn ON the hose heat circuit breaker and turn
the hose heater power control (clockwise) until
the ammeter reads 15 amps. If hose heat is
restored, then the fault is within the gun whip.
If hose heat is not restored, turn the hose heater
power control fully counterclockwise, then turn
OFF the hose heat circuit breaker and the main
power disconnect and proceed with the steps
below:

Troubleshooting
5. Primary Heat and Hose Heat Temperature
Setting - The purpose of the hose heater is not to
add heat but rather to maintain the temperature
developed by the primary heater. If indications are
that the hose heater is not maintaining temperature
during flow, check that the primary heater and hose
are set for the same temperature or reduce the
output.
The hose heat transformer voltage must be set to
match the hose length in use. Too much power will
cause the hose heat circuit fuse to fail. Too little power
will result in insufficient hose heating.
c. Adjust the tap setting of the hose heat
transformer to match the next shortest length of
heated hose (see Hose Heat Power Pack on
page 24).
6. Low Line Voltage - The hose heat system operates
at 220 Volts. Low line voltage will significantly
reduce power available and the heater will not
perform to its full capability at maximum hose
length. A qualified electrician should determine the
secondary amperage of the hose heat circuit and
adjust the tap setting as required to achieve a
secondary amperage of 45-50 amps.
d. Unplug the next set of Power-Lock connectors
and plug the hose jumper plug into the last
“upstream” segment of hose.
7. Hose Heat Transformer Tap Setting - The
transformer voltage is adjustable to accommodate
between 35 ft and 310 ft of hose. Ensure that the
proper tap setting is selected for the hose length in
use. (See Hose Heat Power Pack on page 24).
e. Restore electrical power, switch ON the hose
heat circuit and adjust the hose heater power
control to 15 amps.
If hose heat is restored, then the fault is within
the last unplugged segment of hose.
If hose heat is not restored, turn the hose heater
power control fully counterclockwise, then turn
OFF the hose heat circuit breaker and the main
power disconnect and repeat Steps c through e
until the fault is located.

Proportioning Pumps
5. Shut off both feed pumps and close both inlet supply
valves (F).
When the proportioning pumps are functioning properly,
it is not unusual for a trace amount of resin or isocyanate
chemical to seep past the pump packing onto the pump
shaft. Maintain proper packing adjustment to minimize
seepage. Routinely inspect the shaft and wipe away any
residue when the unit is turned off. Disassemble and
clean both proportioning pumps annually. Inspect the
pistons and cylinders for marks or scratches, which may
cause leakage or damage to packings. As a
