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
of dust collector EWL 5030.
5.3.2 Feed suction hose through the
apertures in the shelf's base-plate and the
table-top of the Formdent work bench or
slide up the cover in the cabinet door
element.
Insert suction hose into suction nozzle
of the extraction point (cut suction hose
shorter if required .
5.3.3 Fit the foot switch at the bottom
and fix it in position by inserting the rubber
feet in the holes provided in the
recess in the base of the pedestal element.
5.4 Press the power switch on dust
collector EWL 5030 to position "0" OFF
and plug the power plug into a correctly
earthed socket outlet.
5.5 Set the rotary switch on the all
purpose blasting station EWL 5423 to "0"
OFF. Insert the power plug into the
socket of the dust collector EWL 5030.
5.6 Fit the compressed-air hose onto
the connection nozzle and screw up
firmly with the hose clip .
5.6.1 Connect compressed-air hose to
the connection provided on site and check
for leaks.
The line air pressure must not exceed
6 bar. If the air pressure supplied is
higher, a pressure reductor unit, ord.no. 620
3642, must be fitted in the line. Use only
dry compressed air!

A 6 Preperations for commencing
operation
A 6.1 Filling the abrasive container
in the recirculating blasting range
6.1.1 Check to ensure that the sealing
cap is properly fitted.
6.1.2 Open the protection shield 1in the
direction of the arrow and fill the all
purpose blasting station EWL 5423 with the
abrasive required (max. grain size 250 mm .
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.
6.1.3 The quantity to be filled is approx.
9.5 kg but must not be above the top edge
of the permanently fitted perforated plate.
6.1.4 Check the profiled joint and clean
if necessary.
6.1.5 Close the protection shield in
the direction of the arrow.
A 6.2 Filling the abrasive containers
inthe disposable abrasive range.

of the arrow.
6.2.2 Unscrew and remove the container
cover , or .
6.2.3 Fill the abrasive container with the
appropriate abrasive according to range.
Range I (red/violet : Grain 25 - 150 mm
Range II (lime green : Grain 25 - 150 mm
Range III (pigeon blue :Grain 100 -250 mm
Depending on the grain, up to approx. 1.5
kg are to be filled in, but the red mark on
the vertical tube must not be exceeded.
In the case of a very fine grain, fill-
ing should be less to avoid any
spillage.
6.2.4 Check O-ring and clean if neces-
sary. Refit container cover.
The all purpose blasting station EWL
5423 is not ready to operate when the
