STARTING THE PAVER
1.0 STARTING
To start the paver first check to make sure the forward and reverse levers are in the neutral
position. The paver will not start if the red indicator light is not “ON” indicating a neutral position.
•Turn key switch to the “ON” position, adjust steer handles until red indicator light is“ON”
•Turn key switch back to the left, position “PRE-HEAT” count to5
•Turn key switch to “START”.
Y If engine does not start quickly, repeat the PRE-HEAT step
•Adjust engine RPM as needed for smoothidle.
CAUTION: Do not Pre-heat more than 5 seconds at a time, or Glow Plug failure will occur.
CAUTION: Do not use any starting fluid, or engine warranty will be VOID!!!!
2.0 DRIVING
The paver will move forward by pushing both levers forward and will move backwards by pulling
the levers back. Steering a course is accomplished by adjusting the speed of one handle relative
to the other. HINT - to make driving easy, push both handles forward to desired speed, then
use only one handle to fine-tune your direction.
3.0 STEERING TENSION
The steer handles can be adjusted for operator preference on tension, (or drag). In a loose
position the handles will spring return to neutral, this requires constant pressure on the handles by
the operator. Tension can be added to the point were the handles are locked and cannot be
moved. The ideal setting is somewhere in-between were the handles have enough tension to stay
in the position the operator chooses, but not so stiff as to producefatigue.
To adjust tension: loosen or tighten the nut located at the center of the aluminum discs were the
handles are attached.
4.0 TWO SPEED
CAUTION: INJURY/OR DAMAGE MAY OCCUR: When switching to high range, bring paver to
a stop before switching. To engage from low to high flip the High range switch up.

MATERIAL FEED OPERATION
The 550-E allows you to configure the auger operation of the paver for both an Automatic mode
and a Manual mode. Use the automatic setting whenever possible to increase the useful life of
the feed augers, and to maintain a more consistent “Head of Material” in front of the screed. In
either mode the lower selector switch can be set to “IN” for reverse material flow.
SETUP Each side of the paver must be set independently.

550E SCREED CROWN SETTING
1a. On a flat surface, find the null position of the screed depth handles by adjusting them until they
are free and not in tension.
1b. Run a string across the leading edge (front) of the main screed bottom, as close
as possible to the bullnose of the screed plate, and adjust the forward
ratchet jack until there is a slight gap (approximately ¼” – ⅜”)
between the screed plate and the string.
*String MUST be on the flat portion of the screed, not on the radius portion*
2. Place the string across the back of the main screed bottom, near the
trailing edge (rear) curvature of the screed plate, and adjust the rear ratchet jack until the
screed plate just touches the whole length of the string. Pull the string away, at one end, and bring it
back to verify that it contacts the entire length at the same time.
*String MUST be on the flat portion of the screed, not on the radius portion*
3. Place the string across the front of the screed bottom and double check the gap between the
screed bottom and the string. Re-adjust the forward ratchet jack as necessary to obtain the ¼” – ⅜”
gap between the string and screed plate.
4. Place the string across the rear of the screed bottom and double check
the gap between the screed bottom and the string. Re-adjust the rear ratchet
jack as necessary to verify the screed plate just touches the whole length of the string.
5. Repeat steps 3 and 4 until no adjustment is required.
550E EXTENSION SETTING
6. Run Extensions all the way out.
7. Loosen strike-off bolts and raise and raise strike-offs all the way up and “hand tighten” bolts.
8. Position extensions so they are at 1’ out on each side (paving width of 10’).
9. Lower screed onto four 24” long 2X4 boards. Lower screed so that the inside edge and outside
edge of each extension are resting on the boards.
10. Null the screed by rotating the cranks until you locate the position of free movement. This is a
limited area where the depth cranks will both rotate freely in either direction. This is the nulled
position. Then, rotate thickness screws 1 ½ rotations, (in the thicker direction).
11. Completely loosen the extension strike-off bolts so that the strike-offs freely rest on the setting
boards.
12. Use wrench to tighten strike-off bolts completely.
13. Start paving and make adjustments as required.

550E SCREED BOTTOM REPLACEMENT –BOLT ON PLATE
1. On a flat surface, find the null position of the screed depth handles by adjusting them until they
are free and not in tension.
2. Find the screed crown null position. “Null” can be achieved by rotating the ratchet jacks until both
forward and rear ratchet jacks are not under pressure and are free to move without the handles.
3. There is a steel flap fully welded to one half and overlapping onto the other half, place three tack
welds on the overlapping side. This is located on the top surface of the screed, between the two
heating burners. This will act to secure the right and left sides in this null position.
4. Unbolt the existing screed plate. Remove any material left inside the open cavity of the screed,
check the heating burner area closely.
5. Install the replacement screed plate.
6. Remove the three tack welds from step # 3.
5. Reset the screed crown, as described in the Crown Setting Instructions.
