A Installation
1) Ensure the frame is level – see Section 3.1.
2) Fit the four 1/4-20 (M6) socket cap screws to the outermost holes on the underside of the breadboard, one in each corner.
3) Fit the lifting handles supplied to the breadboard as shown in Section 3.3.1.
4) Observing the warnings listed above, lift the breadboard into position. As the breadboard is lowered, ensure that the bolts
fitted at item (2) fit correctly into the locating holes in each isolator piston - see Fig. 3.7.
5) Connect the air hose to the air inlet connector on the inside of the upper rear rail – see Fig. 3.7 and Fig. 3.8.

6) Ensure the compressor outlet valve or air supply is turned off.
7) Connect the other end of the hose to the compressor outlet or air supply.
8) Connect the compressor to a suitable mains supply and switch on.
9) Set the outlet pressure regulator to the required pressure. As a guide, recommended pressures for typical loads are as
follows: 175 kg - 20 PSI, 350 kg - 40 PSI, 700 kg - 80 PSI.
10)Wait for the compressor to reach full pressure.
11)Turn the outlet valve or air supply on and wait for all four corners of the breadboard to lift.
12)Using a suitable levelling device, check that the breadboard is level. If not, turn the height adjuster knobs as necessary to
level the breadboard – see Fig. 3.7 and Fig. 3.8.
Warning
During item (4):
When lifting breadboards, use the lifting handles supplied.
Safe lifting precautions must be observed. In particular, do not lift more than 25 kg (55 lb) per person.
Use more people as necessary.
Breadboards should be lifted only in an unpopulated condition.
The space between the edge of the breadboard and the frame is very small. When lowering the breadboard into
position, take care not to trap fingers or clothing.
Note
Items (8) to (10) are applicable only if using a compressor to supply the air.
Note
For further details on the operation of the air compressor see Handbook HA 0103 – Air Compressor.
