# Before and After Connecting Air Supply

It is strongly recommended that the pump is regulated in order to stall at the required tensioning pressure. This process is achieved by the adjustment of the air regulator valve, See also Hydraulic Pump Assembly for component 7.

Before connecting an air supply, it is important to check the following.

- The pressure release valve is fully open (rotate Anti-Clockwise).

- The Dead-mans handle (See also Hydraulic Pump Assembly; part 12 ) is in the normally closed position i.e. in the highest position. To activate the valve, the dead-mans handles is de-pressed down, opening the air circuit.

- The oil reservoir has sufficient oil (Grade ISO 10, 32, 68).

- Check that the cap seal plug has been removed.

The oil tank on this pump unit is fitted with a cap seal plug to prevent oil spillage during transit. Remove the M6 cap screw and seal from tank cap prior to use.

## Air Line Connection Process

Connect the air hose to the air inlet connector. Give the hose a sharp tug afterwards to ensure a solid connection.
