- Page 8 PERATION NSTRUCTIONS Prior to using the Rim Clamp ensure that the lifting pressure has been released from the chain lifting mechanism by allowing the clamp to lightly rest on a flat surface. Once the pressure has been released, the operator may then unlatch the red latch hook by pulling on the hook release chain. This will allow the clamp to open so that it can be lowered onto the pipe (Figure 1). Smaller Rim Clamps, between 4” and 16” in size, may be placed over the pipe manually. Larger size rim clamps must be connected to a lifting device by using the chain lifting mechanism. (Figure 2). ...

- Page 10 When the two (2) pipe joints or pipe and fitting are aligned as closely as possible, determine which reforming screws can be used to reform the pipe to the mating pipe. Adjust the reforming jackscrews as needed to reshape the pipe to match the pipe joint or fitting that is being aligned. The reforming jackscrews should only be used where high spots exist. NOTE: It is not necessary to use all of the reforming jackscrews at the same time. Only tighten the reforming jackscrews that are over the high spots as well as the area of the pipe that is 180° from ...
- Page 11 AINTENANCE NSTRUCTIONS Before and after use, the Standard or Mega Rim Clamp should be inspected. The clamp frame should be checked for cracks or defects in the frame. All moving parts such as the stabilizers, reforming screws, moveable jackbar jackscrews, and red latch hook should be checked to insure proper movement and for any thread damage that may have occurred during use. All slag and debris should be cleaned and/or removed from the clamp prior to the next clamping operation. If the threads on the jackscrews are damaged, the user should use a file to smooth any rough edges to insure that they smoothly move in and out of the jackscrew nuts. The jackscrews should be lubricated with Loctite C5‐A Copper based Anti‐Seize lubricant every 10 hours of operation. Note: Any repairs made to the Standard or Mega Rim Clamp will void the Warranty.
