4.  MACHINE LEG ADJUSTMENT

 - You can now lift the 

machine onto the prepared deck. Adjust the machine legs so 
that the leg span distance is the same as the center to center 
distance between the machine screed rails. Adjust the length of 
the machine legs so that the carriage will clear the deck or slab 
when the machine is placed on the rails. Position the carriage 
toward the idler end of the machine so that the machine will be 
balanced when it is lifted. Position the bogie wheels for clearance 
of the reinforcing steel.

the machine is split the power unit section is self supporting
and stable. Hook up the idler end of the machine to a lifting device. 
Remove the crown bolts at the top of the truss frame and the hinge 
pins on the lower end of the truss frame.

Crown Bolt Assembly

Truss Connection

The idler insert section will now be free to lift and placed to the side. 
Add or remove the required frame inserts on the power unit insert and 
reconnect the idler end section of the machine. Keep the frame as 
straight as possible. When attaching the inserts together it is suggest-
ed that you lubricate the crown bolts. If the deck or slab has a crown, 
assemble the machine so that an insert hinge will be directly above 
the crown. The manual crown adjuster will have to be removed and 
relocated to the correct place on the machine for crowning the truss 
frame. When the sections have been assembled reconnect the carriage 
travel chain, release the paving carriage and add the additional bogie 
hose for the machine bogie wheels on the idler end of the machine.

2.  INSTALLING PAVING CARRIAGE

 - If it is necessary to 

install the paving carriage use the following procedure:

A)  With the paving carriage setting on blocks, remove 

the carriage hanger frame and install the frame into 
truss. Move the machine over the top of the paving 
carriage so that the paving carriage is centered under 
the machine truss. Using the leg cranks, lower the 
machine down until the carriage hanger frame can be 
bolted back on to the carriage. Position the carriage 
in the middle of the machine and connect the travel 
chain. Adjust the hold down roller tension so that the 
rollers can be just turned by hand. The carriage travel 
chain will keep the carriage from moving when the 
machine is lifted onto the deck.

3.  BOGIE INSTALLATION

 - Prepare the machine for lifting (See 

Lifting Instructions) and lift the machine high enough to install 
the machine leg bogies on to the machine legs. Install the drive 
bogies on the rear side and the idler bogies on the front side of 
the machine. The drive chain shield can be on the outside or the 
inside of the leg, depending on clearance requirements. If nec-
essary, add the additional hose provided with new frame inserts.

CAUTION! Make sure that the hydraulic hoses are 

connected so that the direction of machine travel 

is the same as indicated on the control console. If 

necessary, reverse the hose connections at the quick 

disconnect fittings to correct travel direction.

WARNING! Use extreme caution when lifting the pav-

ing machine. Make sure the lifting device has enough 

capacity to lift the weight of the machine. Check 

all chains, slings, lifting cables, clevises and cable 

clamps for strength and for any structural damage.

WARNING! Keep all personnel away from the machine 

while it is being lifted.

WARNING! Before lifting the machine, check to make 

sure that the Machine Legs are LOCKED! If the legs 

are not locked they could roll causing an unbalanced 

lift and personal injury.
