During use

The pump is provided with a control valve. The pump develops oil pressure as soon as the motor runs.
Any pressure developed is released to the tank if the valve is in its "release" position. Only if the pump is
in its "operation" position the oil flows to the tool and pressure develops.
6.3.1 Change a tool
• Disconnect the hoses from the tool in use. Refer to chapter 5.3.
• Connect the hoses to the other tool. Refer to chapter 5.2.
