A concrete foundation pad may be constructed
to elevate the machines. See Figure 34 for a

Installation
Concrete Foundation Pad
1. Verify that the floor is 3500 psi minimum
reinforced concrete embedded in clean,
compacted fill dirt. For 2-speed models,
the floor must be at least 4 inches
(102 mm) thick. For 3-speed and variable-
speed models (except for the 80-pound
capacity model), the floor must be at least
6 inches (152 mm) thick. For 80-pound
capacity models, the floor must be at least
9 inches (229 mm) thick.
2. Break up and excavate the floor to a depth
of approximately 9 inches (230 mm)
below the floor surface, making certain
that the sides of the hole slope outwards
from top to bottom.The bottom of the hole
should be 5 inches (127 mm) larger all
around than the top.
Note that when installation is complete,
the top of the pad should extend a
minimum of 4 inches (102 mm) out from
the machine on all sides.
3. Wet the hole well and brush the bottom
and sides with cement grout.
