SmartROC T35/T40 23 Welding
154 No: 7026962571.1.7027002891 en-US
• Framework, brackets, and load-carrying structures are made of special materials. Any
repair welding performed with incorrect materials or additives can weaken the struc-
ture.
• Avoid welding close to bearings and bushings.
• Do not weld on the boom, hydraulic tanks, hydraulic cylinders, valve blocks, com-
pressed air tanks, or pressure lines.
• Do not weld on a FOPS and ROPS approved cab. The certification would then be in-
valid.
• Protect hoses, cables, and electrical components.
• If possible, grind the surface of the weld smooth and treat it with anti-corrosion paint.
23.2 CAN Bus System Disconnection before Welding
!
NOTE: The CAN bus and RCS can be severely damaged when welding.
NOTE: Consult Epiroc for approval of welding and choice of electrodes.
• Locate all modules present on the machine. Disconnect supply voltage to all modules,
both + (positive) and - (ground).
– Example of modules which can be present: application module, I/O module,
resolver module, and CS-module.
• Locate all sensors on the machine and disconnect them.
• Locate the safety controller and disconnect supply voltage, both + (positive) and -
(ground).
• Locate all panels included in RCS and disconnect supply voltage, both + (positive) and
- (ground).
• Remove the battery ground cable.
