2. Putting into Service
2.1. Electrical connection
Ensure that the mains voltage is correct! Before connecting the unit,
check that the mains voltage is the same as specified on the rating plate.
Only operate the machine off the mains using a 30mA fault current pro-
tected switch (FI breaker).
2.2. Handling and selection of the drain cleaning cable required
The machines ROLLER’S Metro uses lengths of cable which can be
connected up as necessary. The machine ROLLER’S Metro 22 comes
either with the tool set 16 or 22 or both. The machine ROLLER’S Metro
32 comes either with the tool set 22 or 32 or both. The cables can each
be used without any modifications to the machine. The machine ROL-
LER’S Metro 32 can be used also with the cable and tool set 16 by using
different jaws 16 (accessory). The cables are specially hardened and
highly flexible, and can be quickly extended or shortened by means of
T-groove safety connectors.To connect two lengths, push the T-bar (7)
sideways into the T-groove (8). The spring-loaded thrust pin in the T-bar
component locks the two halves together. To separate them, push back
the spring-loaded thrust pin with the releasing tool (9) and push the T-
bar out of the T-groove. The cables and tools will also fit other makes of
drain cleaning machines. An adapter drum for ROLLER’S Metro 22 and
ROLLER’S Metro 32 each with a Ø 8 mm cable, length of 7.5 m, can be
supplied as accessory (see 3.4.).
The diameter of the cable required depends on the diameter of the
pipe to be cleaned. For guidance see 1.2.
The type of cable required depends on the length and position of the
pipe concerned and the type of obstruction expected. The standard cable
is used for general drain cleaning operations. Being highly flexible, it is
particularly suitable for dealing with tight bends or several bends in
succession. For obstructions presenting particular problems, e.g. when
it is necessary to slice through roots, the drain cleaning cable type S,
made of heavier gauge wire (accessory), is recommended. The cable
with a core (accessory) contains a weather- and temperature-resistant
plastic core which prevents dirt from collecting inside the cable or long
fibres from lodging in the spirals.
2.3. Selection of suitable drain cleaning tool
2.3.1. Straight auger
Used as the starting tool to withdraw a sample, from which the cause
of the obstruction can be determined. Also to clear a solid blockage
caused by textiles, paper, kitchen waste etc., to permit the flow of water.
2.3.2. Bulbous auger
Used for minor obstructions caused by textiles or paper, due to its high
flexibility. The extended club-type head facilitates advancement in tight
bends.
2.3.3. Funnel auger
Used for textile and paper obstructions in particular. Is especially useful
for cleaning larger diameter pipes, due to its generous radius of action.
Can also be used as a recovery tool for cables left in the pipe.
