Step
Sealant is Heating Slowly
1
With the material level half or less, open the loading lid and inspect the inside edge of the
material tank. Check if there is a buildup of old, dried out and hardened material along the top
half of the material tank.
2
If this is the case you will need to drain out (use up) the rest of the material inside the tank.
When the tank is empty, use an air chisel to remove this built up material. Remove as much as
possible all around the tank including the roof of the material tank. Remove all the old sealant
chunks from the bottom of the material tank. This should be done every year or as conditions
require.
3
Check your level of the heat transfer oil, there are 3 marks on the dipstick is for 0°, 70°F, 150°.
These temperatures represent the temperature of the heat transfer oil at the time it is being
checked. See
Table 5-1 Preparing the Machine for Start Up
4
Check your records of the last service replacement of the heat transfer oil. If it has been longer
than 500 hours, or one year, you need to change your oil.
