FOUNDATION
A rigid foundation with sufficient base to support the shear against settling is necessary. Foundation plans are
furnished with the instructions for new machines to help determine location of foundation bolts. Because supporting
subsoil structure varies greatly from one locality to another, we recommend that you obtain the advice of a qualified
construction engineer regarding the construction of your foundation. Regardless of the size or type of foundation that you
use, we suggest leaving top 1/2" low for final grouting.
Important: Some sizes will require a pit in the floor. Make certain that you know the requirements for the foundation
before starting construction. While the foregoing instructions cover recommendations for the ideal type of foundation for
your shear, many successful installations have been made on substantial existing industrial floors. Because floors and
sub-soil differ so greatly, we advise obtaining the opinion of a good civil or mechanical engineer before using an existing
floor for a foundation.
LIFTING
Power Squaring Shears can be easily and safely
handled by cranes of sufficient capacity.
Primary lifting should be done with a cable passed
under each end of the eccentric shaft (Figure 3), located
as close to the side of the housings as possible. When
lifting, make certain that the cable is in the clear and will
not damage other parts of the shear. On some shears, it
may be necessary to attach a third cable from the crane
hook to the table of the shear to keep the shear from
tilting.
If no crane facilities are available, the machine can
be rigged into pace; however, we recommend that you
obtain the services
of a qualified rigger for this work.
Skids should be removed only after the shear has been
moved to location over the over the foundation bolts.

CLEANING
After the shear has been removed from the skids and set In place, It should be thoroughly cleaned of all protective
grease and accumulated dirt. The best method of cleaning is to use rags saturated in good cleaning solvent; however,
since most solvents will remove all traces of oil from the machined surfaces, It will be necessary to go over them lightly
with an oiled rag to prevent rusting. Rags should be used rather than waste to do way with the danger of lint and threads.
Never use an air hose in cleaning your machine because the pressure may force dirt and grit between bearing surfaces.
