Make sure that the pump is not running when carrying out maintenance work.
The ‘Draper’ water pump has been designed to operate over a long period of time.
Continuous satisfactory operation depends upon proper machine care, regular cleaning and
by following the periodic maintenance schedule. If the pump is operating in unusually dusty
or hot conditions the time between servicing the pump must be decreased.
Inspect the water pump and extension cables periodically and if damaged have them
repaired by a qualified person or authorised service body. Do not use the pump with
damaged parts.
