Hot Tap Operation
Close Valve or Squeeze Off Nipple
If the tool was made up with a ball valve in line, close the ball
valve.
If there is no valve, use squeeze off tool to shut off all line flow.
IMPORTANT:
Metric Hot Tap Tool lengths were designed for the
use of ball valves. Consult local regulations about using squeeze
off tools.

Retract Cutter
Pull the cutter away from the main and as far into the tool as possible.
Stand clear of cutter shaft and loosen the movable jaw enough to allow
the bearing housing to come out of the jaw.
The cutter shaft can move back with force when
unclamped from jaw. Stand clear of shaft travel to
avoid the possibility of injury.
Make sure cutter is as far into the tool as possible.

Bleed Off All Pressure
Use standard static charge precautions.
Open pressure relief valve and bleed off all pressure. A hose can
be attached to direct pressure away from personnel.
Explosive atmosphere. Gas can ignite, causing
explosion, death or serious injury. During the
process some of the fluid in the main must be
bled and could ignite. Direct bleed off out of the
work area and avoid static electricity and other
ignition sources.
Remove fusion machine from fitting gland.
