5. Equipment Storage and Re-Use:
a. Turn the tank valves off.
b. Do not store at temperatures above 95˚ F
(35˚ C) or below 45˚ F (7˚ C).
c. The used nozzle should be left on the gun
during storage.
d. Engage the trigger safety lock.
e. Close the supply valves on both “A” and “B”
tanks. Wear eye protection and impervious gloves
f. The dispensing gun is a disposable unit and is
not designed for prolonged storage or
continuous re-use. To help extend the storage
life, it is recommended to dispense a minimal
amount of foam from the gun at least once
every seven days to ensure optimum flow of
chemical through the hoses.
g. Use up the adhesive within 30 days of initial
use.
h. Make certain valves are in correct position
when turning them on and when operating the
unit.
