2.3. Special Risks

Release of Hot Water or Steam
Due mishandling or leaks, hot water or steam may escape and can possibly cause a severe risk of burns or
other personal damage - Always wear a proper personal safety equipment when working with hot tapping
machines !
When relasing the pressure from the drilling device, make sure to keep a sufficient distance between you
and the release hose ! Always wear heat resistant safety gloves when removing the drilling machine from
the valve !
Hazards from Rotating Parts
Note that the drill shaft and drive components rotate during drilling. Be aware of the changes in the torque
at the shaft due to the varying cutting forces.Take a fixed stand and feed very slowly !
When the hole saw stucks during the drilling, reduce the feeding speed or turn the wheel a bit backwards
until the hole saw starts rotating again.
Be careful when operating the machine and use protective clothing
Hazards Caused by the Pressure in the Pipeline
Note that when operating a hot tapping machine there is almost always a pressure inside the mainline that
is been drilled. Always familiarize yourself with the safety rules of the worksite and this user manual before
starting the hot tapping process.
When the pressure in the mainline is > 12 bar it is highly recommended to use the chain block for a safe
release of the drilling shaft. This part is usually not included in the toolbox but can be purchased from the
Danfoss if necessary. Only use chain blocks with a maximum allowable weight > 175kg !
Requirements for the Operator
The hot tapping device may only be operated by persons who are trained, instructed and authorized to use
it.
Operator must know the operating instructions and act accordingly.
