• Any fluid leaks have been removed.
• All safety devices on the machine have proper function.
• The oil level was checked.
• Fixtures of screw connections are checked.
• Removed container covers, screens or filters were reinstalled.
Inspection and maintenance can be done by the operator, disassembly and reassembly of the machine have to
be executed by qualified staff only. Incorrect assembly can lead to danger of accident for the operator and to defects
on the machine.
Generally, hydraulic machines need little maintenance. If the following rules are observed, the machine will have
the expected long life-time and high reliability:
Regular check of exterior damages on the machine.
Regular check of the hydraulic filter/ the hydraulic fluid.
In case of disturbances we recommend sending the machine to the manufacturer.
Disconnect the machine from hydraulic supply prior to disassembly!
Only skilled staff are allowed to execute disassembly and assembly. Check the adherence to the technical
specifications after each maintenance work. Only use genuine spare parts. Otherwise you risk a decrease in
performance and an increase in maintenance work.
There is no warranty for damages and liability is disclaimed, if non-original spare parts are used.
The operator makes sure that all maintenance, inspection and assembly work is done by authorized and qualified
personnel, who is appropriately informed by thorough study of the operation manual.
NOTICE -
Check fixtures of screw connections after work is executed
If necessary: Re-tighten fixing screws
The manufacturer service is available for all maintenance, repair and assembly work.
We assume no liability for improper use or operation!
INFORMATION SHEET
Maintenance of hydraulic tools
Only proper maintenance can ensure constant performance, reduction in wear and thus, a decrease in operating
costs and an increase in service life.
Our hydraulic tools are equipped for an operating pressure of up to 100 bar. Regulator setting for a lower
operating pressure is possible.
The tools should not run empty, because this results in heat and higher wear of the output section and the tool
holder.
The hydraulic oil should be clean. This is ensured by professional equipment.
Clean the connecting parts before connecting the hydraulic hoses.
For an economic use of the hydraulic tools the required sizes of pipe, fittings and hoses have to be adjusted.
Proper greasing of the gear and the tool heads is a must. See the operation manual on this.
After finishing the work the tools have to be cleaned and protected against corrosion.
Visible grease nipples are provided for regular lubrication of the gears with a grease gun, or the gearboxes have
a long term greasing.
Note the following for grease lubrication: Every 60 hours of operation check striking mechanism, friction bearings
and antifriction bearings; if necessary, grease them. Every 300 hours of operation grease the gears and antifriction
bearings anew. In the case of impact wrenches, use a grease gun to grease the anvil guide before beginning daily
work, or every 6-8 hours.
All inner parts of the drive (tool holder must be lubricated before storing for longer periods of time in order to
