Place jaws in the lowest hole and centred respect the spindle.
4.
Apply hydraulic force. Do not exceed the 80% of the nominal capacity of the equipment.

6.
When using the Bearing puller, do not exceed the 50% of the nominal capacity of the equipment.

1.
The whole set delivered in a strong wooden box to protect the equipment from damages during the transport. Once the application is finished clean the
equipment and store it in the box until the next use.
2.
Unpack the equipment checking that all the pieces described in the spare part sheet are in; and that have not suffered damages.
3.
Connect the hose and the quick coupler, assure a perfect connection.
4.
Pump several times with the lever; check the screw is slightly opened (turn left) to purge the circuit.
5.
Close manually the screw (turn right). When we pump, the piston will advance. If we open the screw again, the piston returns thanks to the spring.
