Welding Information
If factory authorized welding repairs are required on your Wittke Retro front loader, please keep in
mind that in most cases the material being welded is either high strength, low alloy steel or abrasion
resistant steel. Welding materials of this type requires the use of low hydrogen electrodes (EXX18).
Remove all paint at the weld area, and be cautious of hydraulic lines and electrical wiring harnesses.
Electrical System
The electrical system consists of numerous components connected by generic harnesses. Proximity
switches provide safety lockouts and work in conjunction with the operational controls located in the
control panel. The electrical control system activates air solenoid valves that in turn provide
controlled air pressure to the main hydraulic directional valve. In other words, the system may be
described as ‘electric over air over hydraulic’.
