OPERATIONS
SECTION 1
• SECTION ASSEMBLY •
STEP 1:
Screw jam nuts onto top pipe. Start the top
pipe coupler onto the top pipe of the mating truss
section. Only thread the coupler on about three turns.
NOTE
: The right and left hand jam nuts will already be
installed on the screed section.
TIGHTEN JAM NUTS AFTER SCREED IS LEVEL
The following figures describe the proper instructions for correctly assembling air powered screed.
Make sure that you follow the instructions in order. If the assembling of your screed is not done in
this order, there could be some problems in trying to maintain floor flatness because your screed is
not level. Levelness of your screed is critical!
STEP 3:
Vibrator mounting bolts should be
loose so that the splice plate can move in the
clearance holes. With a 15" adjustable wrench,
turn top pipe coupler until screed and bullfloat
blades contact. Then back coupler off slightly
so the blades touch without tension.
STEP 2:
Slide screed sections together until top
pipe threads on screed marked “R” line up with
threads in coupler on the screed. Start coupler
on adjoining threads by hand to prevent cross
threading.
STEP 4:
Secure the sections together by
assembling the remaining 6 bolts and nuts, tighten
them firmly. Continue joining sections together in
this manner until you have all the sections
assembled. Now you are ready to stringline your
screed. See PAGE S1-15.
