from under the vehicle and so that the handle can be moved up and down without fouling any part of the vehicle.
3.2.3. Raise the saddle to the lifting point. Ensure that the saddle is correctly centred beneath the lifting point.
3.2.4. Pump the handle up and down using full stroke until the required lift is achieved.
