Operation instructions
The KLW4000N air hydraulic pump is designed for hydraulic torque wrench tools. The pump contains a 2-way, 4-position air control valve.
Port A is a high pressure point which exports the oil at high pressure and port B is a low pressure point which returns the oil at low pressure.
1.
Please loosen the valve to adjust pressure before operating.
2.
Connect the air line the input connector to enable starting of the pump.
3.
Please press the working button on the controller and adjust the pressure unit to the required working pressure. Then release the working
button on the controller.
4.
When the desired pressure is reached, the motor will stop working and the pressure will stay the same. When the pressure drops, the motor
will start to work again.
5.
When the motor is working and the “Off” button on the pump is pressed, the motor will stop. The piston and pressure will stay in this position,
even if the pressure drops.
6.
After operating, ensure you press the rubber button on the top of the air control valve in order to vent and release the pressure in hoses and
