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-assembly. 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 the re-assembly check all parts for wear and damage and replace them if
necessary.
Generally replace wear parts always (O-rings, radial shaft sealings and bearings).
Grease the items 412, 417, 418, 419, 424, 425, 431, 433, 436, 437, 439, 443, 444, 445, 455
und 456 and oil the items 405, 408, 409, 413, 446 und 458 with oil SAE 5W to 10W.
Fill the drive unit with 50 ml of oil before mounting the cover item 415.
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)
Saponification type
Worked penetration
Temperature range
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.
