Repair
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:
Consistency class
(DIN 51818)
2
Saponification type Lithium
Worked penetration 265 to 295
Temperature range -25°C to +125°C
The proper quantity of grease is very important from the point of good lubrication and low heat generation.
Spare Parts
Only original spare parts may be used. There is no warranty for damages and liability is disclaimed, if non-
original spare parts and accessories are used.
