Connecting the Pump

Connections can be made to the pump either directly or using the range of 
adaptors supplied in the optional test kit.

Direct

The ports can be fitted with any suitable length ¼ BSP male connector, 
sealing either with an o-ring at the bottom of the port or a bonded seal at the 
top.  Fit a suitable blanking plug to an unused port.

Swivel Adaptors (optional)

The single, ¼ BSP, swivel adaptor connects with a range of fixed adaptors.  
Using the knurled grip-feature, hand-tighten (clockwise) the swivel adaptor, 
until it is fully inserted.

Swivel pump head

The pump head swivels through 140° providing optimum viewing angle and 
bench-top operation.  Placing the pump on the bench allows greater force to 
be applied to the scissor-action handles.  Internal stops prevent further 
rotation of the pump head.

Note:

Do not use excessive force when rotating the pump head.

Selector Valve

Pressure

Turn the selector valve fully clockwise (in) position.

Vacuum

Turn the selector valve fully anti-clockwise (out) position.

Vent

Slowly turn the selector valve to the centre position.

Scissor-action Handles Limit Adjuster 

Turning the limit adjuster (4) clockwise reduces the stroke of the scissor-
action handles (5), turning the limit adjuster (4) anti-clockwise increases the 
stroke.
For maximum pneumatic pressure generation, turn the limit adjuster fully 
anti-clockwise.
