WARNING
Anchor installation can puncture underground utility service.
Can cause property damage, serious injury, or death.
Locate and avoid all underground-utility services before
installing an anchor.
Bolt the Locking Dog Assembly to the Kelly Bar Adapter
(a Torque Indicator may be inserted between them) using
the bolts, lockwashers, and nuts provided (both must have
the same size bolt circles or a Bolt Circle Adapter must be
used). The bolts provided with each Locking Dog Assembly
are hot dip galvanized, and are the appropriate length for
attachment to another flange of equal thickness with clear
-
ance holes (not tapped holes).
Tighten the bolts to the recommended torque values shown
in the table on the right.
Note: Galvanized bolts cannot be used to attach the
adapter to another tool having tapped holes (such as the
Chance Torque Indicator). When using a Torque Indicator
use the plated bolts provided with the Torque Indicator to
attach the Kelly Bar Adapter and Locking Dog Assembly
and tighten to the recommended torque values shown in
the table on the right.
Read, Follow, and Understand this instruction sheet completely
before installing an anchor. These instructions are intended to
illustrate the use of Locking Dog Assembly. Anchor installing
tools covered in this instruction sheet must be used by com-
petent personnel familiar with and following good work and
safety practices. Should additional information and details be
desired, or if specific situations arise which are not covered
adequately herein, the user should refer to Chance directly.
In some cases, Chance may make specific recommendations
concerning installation torque and installation depth for a
particular application.
