9. Check for and remove as necessary, any asphalt
buildup inside the Tracks.
10. Make a general inspection of the machine for loose
bolts and/or components.
11. Make sure safety Guards and Covers are in place.
If the Paver is found to be in need of repair or in any
way unsafe, or contributes to an unsafe condition, the
matter shall be reported immediately to the user’s des-
ignated authority. The machine shall NOT be operated
until it has been restored to a safe operating condition.
PAVING AT THE JOBSITE
The following areas should be “sprayed down” with
asphalt releasing agent (use the Spray Down Hose)
before paving and four times or more during the work
day. These areas should also be cleaned throughly after
each use of the machine:
Hopper, Augers and Screed (bottom).
Push Rollers.
Hydraulic Fluid Reservoir.
Asphalt Depth Adjustment Screws.
External Track and Sprockets.
Any part of the machine which contacts asphalt.
With the Engine warmed up, proceed as follows:
Positioning The Paver
1. Place Throttle in full “open” position and pull out
the Exhaust Diverter Handle. The exhaust will pre-
heat the Screed in preparation to lay asphalt mate-
rial. When operating, the Throttle should
ALWAYS be at full RPM’s. The exhaust can be re-
diverted out through the Muffler periodically if
desired.
2. Maneuver the Paver into position for laying
asphalt with the Track Control Levers.
3. With Paver in position, move the Screed Control
Lever to “down” and hold until the Screed Lift
Cylinder is fully extended. This permits the Screed
to float free. Screed should be lowered onto a start-
ing pad of asphalt or blocks of the desired paving
thickness.
4. Manually adjust the Screed Depth Control Screws
up or down, as required, to a neutral or free posi-
tion. Slowly turn the Screws toward the “up” posi-
tion until a slight amount of tension is felt. The
Screed is now set to lay asphalt to the approximate
thickness of the starting pad or blocks onto which
the Screed has been lowered.
5. Move the right and left Flow Gate Control Levers
to the the “closed” position and hold until both
Gates are fully closed. Set the Alignment guide on
each side of the lower front frame.
Filling The Hopper
6. Have the dump truck back up to the front of the
Paver until the truck tires are 1 to 2 inches from the
Push Rollers. Then move the Paver forward until
the Push Rollers contact the rear tires of the truck.
Do NOT raise the Screed.
7. Move the Hoper Control Lever to the “up” position
and hold until the Hopper almost touches the frame
or dump body of the truck.
8. Signal the truck driver to slowly raise the dump
body, allowing asphalt to flow from the truck into
the Hopper. Be prepared to lower the Hopper to
prevent the truck dump body from striking and
damaging the Hopper as the truck dump body is
raised. Fill the Hopper with asphalt.
9. Move the Flow Gate Control Levers to the “open”
position and hold until Flow Gates are completely
open. Asphalt will then gravity feed down to and
form a head of asphalt at the leading edge of the
Screed.
10. If the area to be paved is level and pushing the
truck is desired, place the Hydraulic Pump Speed
Control Lever forward approximately 1/3. The
CAUTION
NEVER operate the Paver with safety Guards
or Covers removed.
CAUTION
Do NOT spray Tracks before loading or
unloading as this could cause loss of traction.
