Other problems
Disassemble the tool until only if you are skilled and have the appropriate technical knowledge.
Problems could be in the hydraulic power supply, the gearbox module, or the power and control (rear)
module. Then only disassemble the tool as necessary to repair as required.
Keep contaminants such as dirt and grit away from the internal parts at all times.
Always determine and correct the cause of the problem prior to re-assemble. Further wear and tool failure
can result, if the original cause is not corrected.
PRIOR TO DISASSEMBLY
Clean the exterior of the tool.
Make sure to have all new seals so they can be replaced during reassembly. Note the orientation of seals
before removal. Install new seals in the same position as the original seals.
Note: For orientation of the parts refer to the sectional drawing and parts list located at the end of this
manual.
RE-ASSEMBLY
Before starting reassembly check all parts for wear and replace them if necessary. Wear parts are in
particular O-rings, radial shaft seals and bearings.
We recommend changing the grease in the gear housing after 300 hours of operation. Use a special-
purpose gear grease only:
