Safety Messages

2.1

Using the Correct Connection Terminal

Use the appropriate cable connection terminal that is compatible with
the fitting type used. Be sure the contact is firmly established and do not
use burnt cable connectors or push-on terminal adapters that are not
designed for the intended use.
2.2

Improper Use of the Welding and Power Supply Cables

Do not carry the HST300 Junior + / Junior by its cord and do not pull the
cord to unplug the unit from the socket. Protect the cables from heat,
oil, and cutting edges.
2.3

Securing the Fitting and the Joint

Use clamps or a vice to secure the fitting and the joint to be made
before welding. The fitting manufacturer's installation instructions, DVGW,
DVS, European and national regulations will have to be respected in all
cases.
The welding procedure for a fitting must never be repeated, since this
may cause parts under power to be accessible to the touch.
2.4

Tool Maintenance

Keep your tools clean to ensure proper and safe work. Respect the in-
dications and instructions about their maintenance.
