Chapter 2 Safety
©2021 by Crafco, Inc. All Rights Reserved………………………………………..…………………………………Safety 2-1
2.0 Safety Precautions
For more in-depth safety information, please see Safety Manual (PN 26221) which comes with the
machine. Or contact your nearest authorized Crafco Distributor at crafco.com/Distributors.
2.1 General Safety
•Crafco, Inc. assumes no liability for an accident or injury incurred through improper use of
the machine.
•Read this manual thoroughly before operating the machine.
•Obey all CAUTION and WARNING signs posted on the machine.
•Make sure an operator fully knows how to operate the machine before using the machine.
2.2 Personal Safety
•The high operating temperatures of this machine and the sealant it contains requires that
protective clothing, gloves, hard-soled shoes, and safety glasses or a face shield be worn at
all times by operators of the machine.
•Prevent water from going into any part of the machine. If there is indication of water in the
heat transfer oil system, warm heating oil to 250-300°F for 2 to 3 hours.
•Bodily contact with hot sealant or heat transfer oil can cause severe burns.
•If the mixer is not stopped before adding solid material, hot material can get on an operator’s
body and cause severe burns.
•Keep hands, feet, and clothing away from all moving parts.
2.3 Equipment or Operational Safety
•Do not operate the machine in buildings or work areas that do not have sufficient airflow.
•Shut-down the burner and the engine before refilling the fuel tank.
•Make sure the mixer stops before adding solid material to the sealant tank. Lift the lid, place
the material on the lid and close the lid. The mixer should restart automatically.
•Always keep a correctly maintained fire extinguisher near the machine and know how to use
it.
•DO NOT heat transfer oil to a temperature of more than 525°F.
•DO NOT put too much heat transfer oil in the reservoir. The expansion of oil while it heats
up can cause overflow. Check the oil each day before starting the burner. With the machine
on a level surface, check the heat transfer oil level using the mark on the dipstick closest to
the current oil temperature (0°F, 70°F, or 150°F) See Fig. 5-2 Heat Transfer Oil Dip Stick.
Add oil if required. Use only recommended heat transfer oil. Change the oil after 500 hours
of machine operation, or one year, whichever comes first.
•Follow the operating instructions for starting and shutting down the burner. Instructions are
mounted on the control box on the machine.
•Calibrate the temperature control operation after each 50 hours of machine operation. Refer
to section 6.11 Temperature Control Calibration.
•Replace any hoses that show signs of wear, fraying or splitting.
•Make sure all fittings and joints are tight and do not leak each time the machine is used.
•Do not leave the machine unattended while the burner is lit.
•Tighten all bolts and screws every 100 hours of machine operation.
