ELECTRICAL SYSTEM

Welding

The following applies to arc, MIG, TIG and all other electrical welding methods.

IMPORTANT INFORMATION

When performing electric welding on the mower, take all necessary precautions to prevent damage to the electrical system.

The engine’s ignition system has sensitive electrical components. Electrical welding must not, therefore, be carried out on the engine. Remove the component to be welded (e.g. the muffler) or the ignition system. Before carrying out welding on any other part of the mower:

1.Remove the battery cables.

2.Disconnect the connector between the engine pigtail and the frame harness.

3.Connect the welding earth lead as near as possible to the point of welding.
