5.For two-piece mounting, separate the base from the motor assembly by lifting the motor while pulling the plunger (Figure 13) located in rear of the left post (front view). When lifting the motor assem- bly, use the handle.

WARNING

When cutting into an existing system, the pipe must be drained and depressurized. Do not use in the presence of flammable gas, vapor or dust.

cut. To do so, place the base on top of the work- piece. The front edge of the base is 19/16″ inches from the chuck centerline. (Figure 14)

8.Turn crank handle fully counterclockwise to make sure the hook is completely lowered and aligned with the mark in casting.

9.Hook the chain into the base latch.To do so, pull the chain slightly to compress the spring mecha- nism. Once the chain is latched into hook, the spring tension keeps the chain engaged. Use the screw mechanism to fully tighten the chain. (Figures 15 & 16)

NOTE! Completely lower hook until it reaches the cast- ing marks. Failure to do so will result in inade- quate travel to properly tension the chain.
