7. FULL-AUTO MODE (OPTIONAL)
a) Cycle opt ons: "foot pedal", "s ngle workstat on" and "full auto"
DUPLEX PRO has 3 cycle o tions:
Foot- edal mode: de ressing the foot edal causes the arm to move to the other laten and ress.
Single-station mode: de ressing the foot edal causes the arm to move to the other laten, ress and then
return to the original laten.
Automatic mode: de ressing the foot edal causes the arm to move to the other laten and ress. When
the " ost- ress timer" has finished, the arm automatically returns to the other laten and resses again. This is
re eated until the o erator sto s the automatic cycle by ressing the STOP icon or de ressing the foot edal.

SERVICING
TO BE PERFORMED BY QUALIFIED PERSONNEL
THE MACHINE MUST BE SWITCHED OFF AND LOCKED AND TAGGED
PRIOR TO SERVICING
(ELECTRIC AND PNEUMATIC POWER SOURCES DISCONNECTED)
The following tools should be available at hand:
Philli s and flat-blade screwdrivers
Set of o en-ended s anners and box s anners
Set of Allen keys
Multimeter
1. REPLACING WORN PARTS
a) S l cone foam pads
Check that the laten is cold.
Make sure the surface of the laten is clean.
The surface can be cleaned using a mild solvent such as iso ro yl alcohol. Suitable ersonal rotective equi ment
must be worn.
Use RTV-1 glue to stick the foam ad to the aluminium laten (NB: read the instructions for use on the acket).
The ad and the laten must be clean and dry before they are stuck together.
A ly a thin layer of glue evenly over the laten and then stick the ad immediately into lace, making sure there
are no air bubbles tra ed between the laten and the ad (NB: a notched adhesive comb of the ty e used for
floor tiling would be suitable).
Leave to set overnight at room tem erature with a slight ressure a lied and the laten cold.
b) Other parts
Contact your stockist to determine whether they need to be renewed or re aired.
2. Ma ntenance
SEFA heat resses are ractically maintenance-free. Follow the reventive maintenance instructions below to
ensure trouble-free o eration:
Do not heat items that could erish or score the silicone ad or damage the heat laten’s teflon coating.
Clean the machine at regular intervals, with the laten cold, using a clean cloth and iso ro yl alcohol (NB:
iso ro yl alcohol is flammable - use with care and kee away from sources of heat) and wearing suitable ersonal
rotective equi ment.
Kee the heat laten in the raised osition when it is hot but not in use.
DAILY CARE:
Clean the foam ad and the laten’s coating (when cold) with a dry cloth or a dry cloth and grease
remover.
Ins ect the air inlet filter on the left side of the swing arm; drain the filter if it is heavily condensated.
MONTHLY CARE:
Check that the hinged joints are lubricated.
According to use:
Re lace the foam ad every 6 months.
