Unpacking
Check the packaging for any signs of damage. Carefully remove the machine and retain the packaging
until the installation is complete.
Positioning of the machine
Place the Viper 2500s on a clean dry surface, preferable above ground level.

circulation of the cooling air.
• Protect the machine from heavy rain and if used in hot climates, against direct sunlight.
• Ensure that the machine is positioned in such a way so that particles created by grinding and cutting
operations do not enter the machine.

Only use copper welding cables with a cross sectional area of 35mm2 or more.
• Connect the negative (-ve) cable from the power source to the 'negative in' connector on the rear of the Viper.
