Slope MeterSlope Meter
The slope meter is attached to the screed (beside the
crown adjuster lever). The slope meter is used for
slope and crown road construction, and continuously
indicates the slope of the ground, or “percent of grade.”

Indicator Ball
Figure 4-88. Slope Meter
The slope meter is calibrated to read from .00 to .12
(0 - 12 percent) and works similar to a level tool. Just
like a level tool, it contains a ball bearing suspended in
oil that gravity always keeps at the lowest point of the
meter, indicating the slope as you pave. Fluid in the vial
is heavy and helps keep the indicator ball steady even
with vibration, yet it still reacts quick enough to keep you
accurate. While the slope meter is sturdy and functions
regardless of weather conditions, take care not to break
the glass tube. Keep the slope meter clean for optimum
viewing at a glance.
If you selected the slope meter option when your
ordered your paver, it is already mounted onto the
screed at our manufacturing facility. Otherwise, you will
need to mount the slope meter onto the screed.
NOTE: The slope meter is a precision instrument
and must be installed correctly for accurate read-
ings. Install the slope meter onto the metal block
(if equipped), or a solid, straight, at area on the
main screed frame that will not twist or strain during
operation. It cannot be emphasized enough that the
paver needs to be on level ground for correct instal-
lation and operation.
To install the slope meter:
1. Park the paver on a level surface. Use a level tool to
determine that the paver is level before installing.
2. The slope meter comes bolted to an aluminum
mounting plate (two bolts). Remove the bolts and
the slope meter from its mounting plate.
• If your paver is equipped with a metal block
welded onto the screed frame, discard the
mounting plate as you will be attaching the
slope meter directly to the metal block surface.
NOTE: Pay attention to the raised rims around
the bolt holes. The slope meter must be
remounted on the same side to prevent
damage during installation.
3. Align top edge with the frame edge. Use a level to
ensure it is perfectly level.
• If using the aluminum plate, align it onto the
mounting surface carefully, with the top edge of
the plate aligned with the frame edge.
• If installing onto the metal block, use a level tool
to ensure
4. Reinstall the two bolts securely, ensuring the raised
rims are in their original position.
NOTE: If using the aluminum plate, the lock washers
provided MUST be used or the plate can
shake loose.
