2 - OPERATION

2.1 PREPARATION In order for the "CMS" series of casing slips to operate properly, it is necessary to install the proper number of segments and size of inserts corresponding to the size of the O.D. It is to catch. Follow the procedures in section 4 – Shop repairs.

2.2 OPERATION

• After installation of the proper size of inserts in the casing slip, the slip is ready for service. The back of the slips and ID

• The bowl should be cleaned and greased before use, and daily during use.

• To set the slips, move the drill string to the desired location and allow it to come to a

complete stop. Place the slips into the tapered bowl or spider, gently lower the pipe, which will allow the slips to wedge into the bowl or spider and hold the pipe from moving.

• When lifting slips out of the bowl firmly grip and apply inward pressure to the front

handles of the slip as the pipe is lifted. Then, let the upward movement of the pipe lift the slip out of the bowl. Once the slip is clear of the bowl pull on rear handles of slip to clear the bowl.

CAUTION: • Be sure to use the handles provided on the slip assemblies for raising the slip

assembly in and out of the bowl.

• Be sure drill string is at a complete stop before setting the slips into the bowl. This will cause the slips to be overloaded and can cause damage to the slips. Do not use slips as a backup.

• Make sure the slips are used with the proper size of inserts and slip backs are cleaned

and greased daily. Also be sure that the taper on the slip matches the taper on the bowl.

3.1 INSPECTION To insure optimum performance from the "CMS" series of casing slips, the following checks should be made once a week.

• Check for worn hinge pins and handle pins and replace as necessary.

• Check inserts for wear and replace as necessary.

• Slips should undergo a magnetic particle inspection a minimum of once a month, when in use and after every job.

• Slip backs should be checked with a straight edge weekly.

3.2 LUBRICATIONS Lubricate the slip regularly during usage and storage to prevent corrosion. Use an extreme pressure, multi-purpose, lithium base grease of no. 1 or no. 2 consistency and multi-weight motor oil. When the tool is in use, lubricate the slip according to the following schedule or annually while in storage. Daily: Clean and grease slip backs and bowl ID. Weekly:
