Requirements to the air supply
- The pneumatic impact wrench is designed for an operation pressure of 6(4) bar. Pay attention
that the operation pressure is not lower.
- For maximum performance, the values given in the table "Technical Specification" have to be
met.
- The distance to the machine should not be bigger than 5m.
- The supplied compressed air has to be free from foreign objects and humidity, in order to protect
the pneumatic wrench against damage, dirt and rust formation.
- For the lubrication we recommend installing an oiler or a maintenance unit upstream the
machine.
- This ensures a proper functioning of the pneumatic impact wrench. Always use acid and resin-
free oil (SAE 5W - SAE 10W).
- Oils of high viscosity cause vane sticking and impair the start and performance of the machine.
Optimal lubrication will multiply the service life time.
- In winter, or if the compressed air is very moist, an antifreeze lubricant, e.g. "BP-Energol AX 10",
"Kilfrost" or "Kompranol N 74" should be used.
- Pay attention that the diameters of all lines are big enough and there are no restrictions. There
must be no buckles in the hoses. Check the supplied flow pressure.
- The flow pressure has to be adjusted with the pressure control valve (see technical
specifications). Supply hoses have to be designed for a minimum operating pressure of 6 bar.
Replace hose lines regularly at preventative maintenance, even if there are no damages (observe
the instructions of the manufacturer).
- Always use hoses, which have an oil resistant inner surface and an abrasion-resistant outer
surface. If you are next to electric conductors, always use hoses which are proved and specified
to be non-conductive.
- For use in areas exposed to explosion hazards always use hoses and lubricating oil, which meet
the safety requirements of the owner.
