NOT overfill or spillage may occur when the oil is heated and expands. See Figure 5.2
Heat Transfer Oil Dipstick
5
Make sure all toggle switches are turned “OFF” and all temperature control dials are
set to their minimum settings.
WARNING
The safe operation of this machine is the operator’s responsibility.
Use extreme care when operating this machine; safety is the result of being careful
and paying attention to details. Remember the propane flame is approximately
2,200°F (1204.4°C). Some exposed parts of the machine reach 500°F (260°C), the
sealant 400°F (204.4°C), and the hydraulic fluid 180°F (82.2°C).
Always put on protective clothing, gloves, hard-soled shoes, and safety glasses or a
face shield. Be sure that all joints and fittings are tight and leak proof. Immediately
replace any hose, which shows any signs of wear, fraying, or splitting. Tighten all
bolts, nuts, and screws every 100 hours.
Table 5-1 Preparing the Machine for Start Up
5.0 Operating Instructions
The Crafco Super Shot 60 Diesel was developed to melt Crafco sealants. However, it works well
with most road asphalt and federal specification crack or joint sealants.
Note: DO NOT attempt to operate the machine without using these and all other instructions.
Start the engine. (Refer to the manufacturer’s instructions for the engine).
3
Turn the “POWER” toggle switch in the control box to the “ON” position. The red light
marked “BURNER” will illuminate indicating that the material and hot oil temperatures are
below set point. When the red light goes off this indicates the material or oil temperatures
are up to the set point.
NOTE: Just because this light is illuminated does not indicate the burner is actually
working.
4
Set the heat transfer oil temperature at 500°F (260°C).
5
Set the material temperature to the manufacturer’s recommended temperature.
CAUTION
If the burner does not ignite the first time, turn the “POWER” toggle switch to the “OFF”
position. Turn the toggle switch to “ON” again; the burner should ignite. If the burner still
does not ignite, refer to 8.0.1 Symptoms: Burner will Not Ignite to determine the
malfunction.
Important:The solid material in the tank melts first around the walls and bottom of the
tank. The material temperature sensor is located by the wall, therefore, it is possible that
at the beginning of the melting process the indicated temperature reaches operating
value, but the material between to the center tower and the outside wall of the tank is still
solid. This is normal, and when the heated hose is ready for operation, most of the
material in the tank will be melted and heated to the proper application temperature.
6
Allow the heat transfer oil to continue to heat.
7
When the material reaches 275°F (135°C), the mixer light will illuminate which indicates
the mixer can be engaged by turning the toggle switch at the control panel to
“FORWARD” position. If the mixer does not move, allow the material to heat longer.
Note:Mixer speed is preset at the factory and cannot be adjusted. The mixer cannot be
engaged until the material reaches 275°F (135°C).
CAUTION
Jamming the mixer can cause the hydraulic oil to overheat and damage the machine.
8
The hose automatically turns “ON” when the material temperature reaches 275°F
(135°C). The red light marked ‘HEATED HOSE” will illuminate when the hose control is
calling for heat.
9
Adjust the temperature dial to the manufacturer’s recommended temperature.
Note: The hose reaches operating temperature in approximately 30 minutes.
After the hose reaches the temperature set point, the light in the control box marked
“HEATED HOSE” turns off.
11
Once the hose reaches 325°F (162.8°C) the red light marked “PUMP” will illuminate
indicating that the temperature interlock will allow operation of material pump.
Important: The hose must reach 325°F (162.8°C) before dispensing can take place. If
the hose does not dispense when the trigger is activated, allow the material to heat
longer. If the hose still does not dispense, shut the machine down, locate and remove the
plug in the line.
12
See Table 5-7 Dispensing the Material .
CAUTION
DO NOT twist or kink the hose.
Avoid sharp bends and continuous twisting by maintaining a minimum 10-inch bend
radius.
DO NOT use a setting on the hose controller if more than 400°F (204.4°C).
DO NOT move or bend the hose when cold: it can cause damage to the hose.
DO NOT leave the hose cycling for longer than 30 minutes without dispensing material;
coking can occur and permanently damage the hose.
DO NOT remove the hose from the boom during operation or kinking will occur.
Important: It is strongly recommended that the hose be stored in the boom (locked
position) when not in use or when in transit. This will prevent twisting or kinking.

5.3 About the Heated Hose, Wand, Valve, and Tip Guard
The Heated Hose
The heated hose supplied with the machine is Teflon-lined with steel over braid. It has a heating
element, which runs the length of the hose to heat the material within the hose. The hose is
covered with high temperature, durable rubber.
The Wand
The wand has an aluminum tube to protect both the wand and the operator. The pistol grip actuator
is equipped with an electric switch which, when depressed, sends a signal to actuate the pump.
The wand is equipped with a trigger lock to prevent accidental pump actuation when it is not
pumping material. The trigger must be in the “LOCKED” position at all times except when
intentionally pumping material.
The Valve
The wand has a disposable duckbill valve on the end, which shuts off the flow of material when the
pump is turned off and prevents excessive dripping of material. This valve also directs the material
into a stream for easy application into the crack. Other sealing tips are available. See 10.0 Tools
and Accessories for other sealing tips and options.
Tip Guard
The wand has a Tip Guard installed at the factory only when a duckbill is installed. This Tip Guard
is not required when using sealing disk or dripless tip adapter. The purpose of this guard is to
prolong the life of using a duckbill and to protect the operator in the event of a duckbill failure.
Ensure this guard is installed properly before operating equipment. See below.
Twisting and kinking of the electric hose (used on BAX, Super Shots, and EZ Series
Melters) causes the hose to fail; the electric heating wires are shorted out to the metal
hose cover and the hose stops heating.
This type of failure is not covered under the Crafco warranty.
1
Set the hose temperature at 193.3°C (380°F), or manufacturer recommended operating
temperature.
2
Allow the hose to be turned “ON” and heating for a minimum of 30 minutes.
3
Make sure the hose swivel between the hose and wand moves freely.
Note: Do not twist or bend the hose over sharp edges such as the edge of the frame or
tank. Crafco, Inc. recommends you do not work directly under the boom; this may cause
damage to the hose.
4
Follow all machine instructions in this manual.
CAUTION
Hose damage occurs if:
The hose is bent or moved when cold.
The hose is twisted or bent at a sharp radius.
The hose is moved before being heated a minimum of 30 minutes and set at 380°F
(193.3°C).
The operator crosses over or under the hose causing the wires between the hose and
wand connection to twist or wrap up.
The swivel is cold and is not flexible which can cause the hose to twist.
The wiring between the hose and the wand is pulled, stressed, or used to support the
wand.
Step
Action
1
Leave the hose in the boom, swing the boom clockwise towards the front of the
machine and lock the boom into position with the latch provided.
2
Place the wand in the wand holder and lock the wand into position with the latch
provided.
Personal injury could occur if this safety system is disabled.
Step
Action
WARNING
Following this procedure prevents hot material from getting on operators and causing
severe burns. Never throw blocks of material directly into tank. Hot material splash
hazard will result.
1
To load material into the sealant tank first open the lid.
2
Place the solid material on the lid then close the lid.
3
Continue adding solid material at intervals to allow the mixer to rotate without
jamming.
Note:If blocks of solid material are added too quickly, jamming results and slows
down the melting process.
Note: When sealant placement volume is low, or the crew has stopped working for
lunch hot oil and material temperatures can equalize. To lower material temperature
add a few blocks of cold sealant. This may not be an option if the tank is full.
Table 5-5 Loading Material into the Sealant Tank
5.6 Loading Material into the Sealant Tank
This unit is equipped with a safety interlock system on the loading door. This system disables the
mixer hydraulic system when the lid is open to stop the mixer from turning. This is a safety feature
for the operator and should never be disabled for any reason.
Put on protective clothing, gloves, hard-soled shoes, and face shield or safety glasses
when operating or filling this machine. Read the entire manual before operating the
machine.
Never point the wand at any part of the body or at any other person. Hot material can
cause severe burns.
Important:Some difficulty may be encountered when starting up on cold days.
Although the wand is designed to heat the material all the way down to the tip, on cold
days you can place the tip of the wand under the lid to facilitate material melting in the
valve. Insert the wand tip for only a short time before proceeding.
1
When the material and hose have reached manufacturer’s application temperature,
you are ready to dispense material.
2
Turn the pump speed control to the lowest setting by turning the speed control knob
fully clockwise.
3
Insert the wand tip under the lid, depress trigger on the wand and slowly increase
pump speed until the pump motor starts to turn.
4
Adjust the pump speed for the desired flow rate for the application. The rate of flow
may be varied while the pump is running.
Leaving the hose in the boom, swing the boom clockwise towards the front of the
machine and lock the boom into position with the latch provided.
CAUTION
DO NOT kink or twist the hose or permanent damage may result.
2
Place the wand in the wand holder and lock the wand into position with the latch
provided.
3
Reverse the pump for approximately 30 seconds.
4
Turn the mixer toggle switch to the “OFF” position.
5
Turn the “POWER” switch to the “OFF” position.
6
Stop the engine by turning the key to the “OFF” position.
Table 5-8 Shutting Down the Machine
5.8 Shutting Down and Cleaning Out the Machine
When shutting down the machine for the day, Crafco recommends leaving the melter about half full
with material. This will give a fairly rapid heat up rate in the morning, but allows enough material to
start dispensing right away when the material becomes molten.
5.9 Storing the Machine
Store the machine in an area where moisture cannot enter the heating system such as the heat
transfer oil tank, etc. Extended down time can cause moisture build up in the heating tank.
Evidence that moisture has collected in the heat transfer oil is a constant popping noise. If this
popping noise is heard, warm the heat transfer oil to 300°F (148.9°C) for two to three hours to
evaporate the moisture. Failure to follow this procedure will cause the heat transfer oil to overflow
the tank resulting in possible machine damage and/or personal injury.
Best practice is to check in the material tank prior to starting the burner. If water is present, try and
remove as much as possible, heat the material to 300°F (148.9°C) for two to three hours to
evaporate the moisture. Failure to follow this procedure will cause the material to overflow the tank
resulting in possible machine damage and/or personal injury.
Store the machine for longer periods with the material tank empty.
This chapter contains all normal maintenance instructions to properly maintain your machine.
6.1 Engine

6.9 Temperature Control Calibration
Check the control knob calibration weekly. Calibrate by turning the knob counterclockwise. If the
marks do not align, loosen screw in knob and align the line on the control knob with the calibration
mark on the scale plate. (See Figure 6.2 Scale Plate)
The heat transfer oil in this machine is a grade that has been tested and recommended by Crafco,
Inc. Using a grade of oil not specifically recommended by Crafco, Inc., is cause for warranties to be
voided.
All oils subjected to high temperatures deteriorate with time and lose many of their characteristics.
Tests conducted by Crafco, Inc. have determined that for best results and safety, the heat transfer
oil in this machine must be drained and replaced with Crafco, Inc. recommended oil after five
hundred (500) hours of machine operation or one (1) year, whichever occurs first.
Bring the melter to temperature as preparation to drain the sealant tank.
2
Remove the pipe cap located at the rear of the machine and drain the sealant tank.
WARNING
The material in the sealant tank is extremely hot. Bodily contact with hot sealant can
cause severe burns.
The high operating temperatures of this machine and the sealant it contains require that
protective clothing, gloves, hard-soled shoes, and safety glasses or a face shield be
worn at all times by operators of the machine.

16
Clean any sealant from the top of the pump mounting plate and clean the shaft holes.
(See Figure 6.3 Material Pump Replacement)
CAUTION
Premature pump wear results if the pump mounting plate and bolt holes are not
properly cleaned.
Melters use 12-volt direct current (DC) to power the burner, hydraulic valves, and trigger on electric
wand. The DC power is from a 12-volt battery.
The electric hose and wand uses 24-volt 3-phase alternating current (AC). The AC power is from
the generator which hangs under the radiator. This system has no reference to ground so there is
no possibility of electrical shock unless you are between 2 of the phases. NOTE: ONLY CHECK
AMPERAGE ON A HOSE WITH A CLAMP-ON AMP METER. ( See Figure 7.2 Clamp – On Amp
Meter/Multimeter)
12-volt DC power has little danger of electrical shock. Care must still be taken when dealing with
DC power systems because it is capable of producing large amounts of current.
7.1 Checking DC Voltage with a Multimeter
Connect the probes to the meter.
Set the range to a position that includes 12-volts or higher.
Touch the red probe to the positive side of accessory and black probe to ground. If the item you
are checking has a ground wire attached then use that ground or you can use a non-painted
surface on the frame.
7.2 Checking AC Voltage with Multimeter
Connect the probes to the meter (See Figure 7.1 Standard Multimeter).
Set the range to a position that includes 24-volts or higher.
There are three steps to test the generator voltage. All 3 values should be in the range of 24-30
volts AC.
•Touch red probe to the white wire of the generator and the black probe to the green wire of
the generator.
• Next move black probe to black wire.
• Then move red probe to green wire.
7.3 Checking Resistance (Ohms)
Connect probes to the meter (See Figure 7.1 Standard Multimeter).
Note: When checking Ohms the circuit cannot be completed. This means one end of the wire will
need to be disconnected.
7.3.1 How to Check Wire Continuity
Set the meter to “Audible Continuity”.
Now touch the probe to each end of the wire in question. The meter will read “0” on the screen and
make an audible beep if the wire has continuity from end to end.
7.3.2 How to Check RTD Sensor
Set dial to Ohms Ω. If your meter has different ranges set to 2K or 2000 ohm range.
Touch one probe to each screw or wire of the sensor. The meter will read X.XX if in the 2K range
The Multimeter can be used to check amperages under 10 amps in AC or DC current.
When checking the amperage of the electric hose always use a clamp-on amp meter (See Figure
7.2 Clamp – On Amp Meter/Multimeter). The amperage in the hose can reach as high as 35
amps.
Clamp the meter around one wire at a time. Remember most clamp-on meters do not work on DC
