Precautions for Welding
Remove paint before welding or heating (see Safety
Section in this manual for more information on paint
removal and high-pressure lines).
CAUTION: Avoid potentially toxic fumes and dust.
Hazardous fumes can be generated when paint is
heated by welding, soldering, or using a torch.
Do all work outside or in a well ventilated area.
Dispose of paint and solvent properly. If you
sand or grind paint, avoid breathing the dust by
wearing an approved respirator. If you use solvent
or paint stripper, remove with soap and water
before welding. Remove solvent or paint stripper
area before welding. Allow fumes to disperse at
least 15 minutes before welding or heating.
IMPORTANT: Welding on the engine is NOT
ALLOWED. If welding must be performed on
the machine, follow these precautions.
IMPORTANT: High currents or electrostatic discharge
into electronic components from welding
may cause permanent damage.
1. Remove paint from the area to be welded and ground
cable clamp location.
2. Disconnect the negative (-) battery cable(s) or open
battery (-) switch if equipped.

3. Disconnect the positive (+) battery cable(s) or open
battery (+) switch if equipped.
4. Clear or move any wiring harness sections away from
the welding area.
5. Welding on engine components is not allowed.
6. Never connect the welder ground to any engine
component or engine driven components that may be
connected to the engine.
7. After welding, reverse steps 2—3.
Precautions For Welding On Vessels
Equipped With Electronic Engine Control
Unit (ECU)
IMPORTANT: ALWAYS disconnect Electronic Control
Unit (ECU) connectors and engine control
system-to-vessel ground before welding.
High currents or electro-static discharge in
electronic components from welding may
cause permanent damage.
1. Remove the ground connection for the engine control
system-to-vessel frame.
2. Disconnect the connectors from the ECU.
3. Connect the welder ground close to the welding point
and be sure ECU or other electronic components are
not in the ground path.
