3 Operation

Initiation

Connect cable assembly to central coupling (1). Be sure that collar nut is fully tightened. Plug earth cable into socket

(7) and lock in position.

Place gas sylinder onto rack at rear of machine and secure with chain. Attach gas hose to pressure regulator and secure with hose clamp provided.

Open gas cylinder valve briefly to clear any foreign matter from it, than attach pressure regulator. Set regulator to required gas flow rate (approx. 10 - 13 ltr./min. - 2.5 - 3 GPM).

Caution: Do not dismantle the pressure regulator for any reason. It may explode when assembled incorrectly!

1-Phase Machines

These machines come fitted with a Schuko 2-prong plug with earth contact as standard. For the U. K. and certain other markets machines are supplied without a plug on the power cord. Connect to power mains only by earthed plug and earthed receptacle matchine your local standard. Mains furse 16 amp time-lag required.

3-Phase Machines

Three-phase machines are supplied with a CEE 5-pin plug on the power cord. If a plug matching your local standard has to be installed, connect only as shown at right. The yellow/green earth lead must be connected

to the terminal marked

.
