n
Check whether the central unit can be started via the low voltage connector (figure 1: 8) of the
central unit by closing the start circuit with a piece of metal wire.
n
In case of suction hoses that are equipped with a handle start mechanism, check that the start
circuit of the hose is intact. If the central unit can be started by connecting the contact pins of a
wall inlet with a piece of metal wire, for example, but not with the control switch on the suction
hose handle, the fault is either in the hose or in the switch.
n
If the central unit can be started via the low voltage connector but not by opening a wall inlet,
check that there are no breaks in the wires.
n
Check whether the overheat protector of the electric motor has tripped (see section Safety
Devices).
n
Check whether the overheat protector of the turbine has tripped (see section Safety Devices).
n
Check whether the overload protector of the electric motor has tripped. If this is the case, the
start relay of the central unit will make a clicking sound but the motor will not start; contact an
authorised Allaway service dealer.
5.2 WHAT TO DO IF SUCTION POWER HAS DROPPED
n
Check that all other wall inlets are closed and that they do not leak.
n
Check that there are no objects inside the wall inlet that could obstruct flow.
n
Check that the suction hose is intact and that no objects that could obstruct flow are lodged in
it.
n
Check that the dust canister is correctly in place and that the sealing materials of the dust canister
are clean and intact.
n
Check that the dust canister is not full or that the dust bag does not require replacing.
n
Check that the filter is in good condition.
n
Check that the pipe system is airtight.
5.3 WHAT TO DO IF THE SUCTION HOSE IS DAMAGED
Cut the damaged section out and reconnect the hose using an extension coupling muff (accessory).
If the hose breaks near the hose coupling muff or the handle, detach the muff or handle, cut out the
damaged section and twist the hose coupling muff or handle back onto the hose. The components of
the hose have a left-handed thread.
In suction hoses equipped with a handle start mechanism, the start circuit wires are built into the hose.
The hose cannot be shortened or extended. In case of damage to the hose, contact an authorised
Allaway service dealer.
