Loading Through Manhole
WARNING: EXTREME CARE MUST BE USED WHEN OPENING MANHOLE
COVER TO PREVENT ESCAPING HOT GASES FROM
CONTACTING THE OPERATOR. A FACE SHIELD AND
GLOVES MUST BE WORN. FAILURE TO EXERCISE CARE
AND WEAR A FACE SHIELD AND GLOVES MAY RESULT IN
SEVERE BURNS OR DEATH FROM ESCAPING GASES.
a. Open the manhole cover slowly to allow any internal pressure to
release gradually. Wear a face shield.
b. To keep the material being loaded from filling the asphalt pump
and the circulation path, make sure Cab Console Valve Selector is
set to OFF.
c. Monitor the filling procedure closely. Do not overfill. Allow space
in the tank for expansion when material is heated.
d. Observe material in tank for signs of boiling which would indicate
moisture. If boiling exists, stop filling at ¼ tank or just cover heat
tubes and proceed to step e. If no boiling exists, fill to desired
level and proceed to step h.
e. On the Cab Console, select “Spread-Heat” and circulate the spray
bar for 10-30 minutes. With optional “Front Suction”, select and
circulate an additional 5 minutes.
f. On the Cab Console, select “Circulate-Heat” and circulate for 5
minutes.
g. Now, shut off the truck engine and listen to the tank. When all of
the boiling, hissing and popping stops, the water has boiled out,
you may continue loading and spreading. The safest practice at
this point is to shoot out the partial load.
h. Close manhole lid and secure.
