safety measures are taken when changing their places.

• If the machine is to be used on a platform, it must be checked that this platform has suitable load

bearing limits.

• If it is to be transported by means of a haulage vehicle (transport trolley, forklift etc.), make sure

of the durableness of the vehicle, and the connection points (carrying suspenders, straps, bolts,

nuts, wheels, etc.) that connect the machine to this vehicle.

• If the machine will be carried manually, make sure the durableness of the machine apparatuses

(carrying suspenders, straps, etc.) and connections.

• Observe the International Labor Organization’s rules on carriage weights and the transport

regulations in force in your country in order to ensure the necessary transport conditions.

• Always use handles or carrying rings when relocating the power-supply sources. Never pull

from torches, cables or hoses. Be absolutely sure to carry gas cylinders separately.

• Remove all interconnections before transporting the welding / cutting equipment, each being

separately, lift and transport small ones using its handles, and the big ones from its handling

rings or by using appropriate haulage equipment, such as forklifts.
