Be careful starting and/or using the throttle on loose gravel surfaces. Loose gravels may be
sucked into the flywheel cooling fins causing damage to the unit.
Carefully identify potential hazards around the intended area of use before you commence
using the pump.
The patented impeller design will pass some vegetable matter but not long fibrous weeds or
sticks of wood. This impeller is self-cleaning and will in most circumstances clear blockages
by the backflush of water already in the discharge hose. For this to occur the engine must be
running at idle speed with some head of water in the hose.
If the impeller becomes entangled and jammed, the pump volute may be removed by
undoing the 5 cross recess head screws attaching it to the aluminium manifold and pulling it
away. Take care not to distort, cut or compress the moulded seal between the manifold and
the volute during removal and reassembly. Clean out all debris and ensure the impeller
rotates freely before reassembly. If the impeller remains locked after all debris has been
cleared, do not attempt to dismantle the pump any further. Return the pump to Flextool
(Aust.) Pty. Ltd.
Keep the unit clean.
Check the oil level in the engine crankcase daily, it should reach the edge of the oil filler
neck. The engine oil capacity is only 100 ml and running the engine with a low oil level will
cause serious engine damage.
The pump head must be handled with care, and be properly maintained in order to avoid
unnecessary breakdowns. Check regularly for signs of wear and rectify any faults
immediately.
The exterior of the flexible drive shaft is subject to abrasion and wear. If the pump is
operated unchecked, water may eventually enter the pump head or the flexshaft. Naturally,
the cost of repairing a pump which has been allowed to deteriorate will be greater. Regular
inspection of the pump head and the flexible shaft will avoid these problems.
Check the flexible shaft for kinks and external damage by laying it out straight on a
workbench or the floor. Although it still operates, a badly kinked flexible shaft may result in a
failure of inner core.
Check the outer casing rubber cover for damage where it enters the ferrule at the pump
head. Damage can be caused by excessive bending of the flexible drive shaft near the pump
head or coupling.
Replace the oil in the motor crankcase with Honda 10W/30 oil after the first month or 10
hours use, then replace once every 6 months or after 50 hours use. Check and replace oil
more frequently when using the engine in harsh conditions.
