2. Oil Flow and Pressure
Your new HYCON earth drill is designed for a certain oil flow, working pressure and
maximum pressure. A too high oil flow and/or a too high pressure results in overload
of the earth drill, meaning that the lifetime of your new HYCON tool will not be as
expected, and that your service and repair costs will be too high.
It is important to check that the earth drill is not supplied with an oil flow beyond its
design capacity, that the working pressure is correct and that the maximum allowed
pressure is not exceeded.
On page 5 you will find the technical data.
The earth drill is mounted with a pressure relief valve (torque limiter). This has been
adjusted to 90 bar from the factory and may not be changed, as it can cause severe
personal injury.
