OPERATING INSTRUCTIONS

A 5 Mounting and connection

5.1 Install the all purpose blasting station

EWL 5423 on the selected site.

Do not operate the all purpose blast-

ing station EWL 5423 without

suction. The extractor must be fitted with

an approved filter (such as in dust collector

EWL 5030 when work invol-ving

noxious materials such as investment

compounds containing quartz is undertaen.

5.2 Dust produced by the all purpose

blasting station EWL 5423 is sucked out

through the extraction point .

5.2.1 Insert suction hose  into hose noz-

zle  of dust collector EWL 5030.

5.2.2 Insert suction hose CP into suction

nozzle  of extraction point on the all pur-

pose blasting station EWL 5423 (cut suc-

tion hose shorter if required .

5.3 Installation of all purpose blasting

system EWL 5423/5030 ith ork-station.

5.3.1 Insert suction hose  into hose noz-zle 

Leave the basket



in the unit when

refil-ling so that any large particles

will remain on the perforated plate and

clogging of the suction system is avoided.
