16. Press foot switch to rotate brush and withdraw flexible drive slowly (hand over hand) from the pipe. Do not
force flexible drive up or down the pipe –allow the brush and machine to do the work
N.B. If resistance is felt then move flexible drive backwards and forwards a few centimetres as you
briefly tap the foot switch on and off. Try again, or wait for your assistant to advise you if the flexible
drive is free from obstruction. If it gets stuck, do not pull hard on the flexible drive, wait for assistant
to help.
It is advisable to have a colleague assist in the cleaning on the floor below to communicate when and where
the brush has come out of the pipe and when to start rotation back up the pipe.
17. The operator MUST keep an eye on the flexible drive behind him when withdrawing it from the pipe –has it
twisted etc? If it has, uncoil in a large arc and start again.
18. If the flexible drive jams up, the motor and/or variable speed unit overload will trip out. Switch machine off,
withdraw flexible drive from spout and allow the thermal overloads to cool down and reset.
If the overload protection trips out regularly, one of the following may be the cause:
a) You are using a brush which is too large.
b) The spout is heavily scaled or blocked.
If none of these is the cause contact Tube Tech International Ltd.
