Manufacturer’s installation of Crack Sealing Machine instructions are being followed.
Melter heat transfer medium is heated to the correct temperature range
Sealant is heated to a minimum of the manufacturer’s recommended pouring or application temperature, but the temperature shall not exceed the materials safe heating temperature.
Sealant is continuously agitated to assure uniformity, except when adding additional material.
Operator wears required personal protective equipment when operating Crack Sealing Machine.
If melter is equipped with a heated hose system, the hose is heated to operating temperature prior to beginning sealant application.
If melter does not have a heated hose, verify that the hose is unplugged and clear prior to beginning application.
If the melter of Crack Sealing Machine does not have a heated hose, sealant shall be recirculated through the hose to warm the hose prior to application. During idle periods, or if it is noted that sealant is cooling through the hose, sealant shall be recirculated through the hose back into the material vat to maintain hose temperature.
Sealant temperature is checked periodically to assure proper temperatures.
