Operation

Run engine at full speed while operating pump.

Pump should begin pumping water within a minute depending on
length of suction hose and height of pump above water. Longer hoses
will require more time.

If pump does not prime, check for loose fittings or air leak in suction
hose. Make sure strainer in water is not blocked.

DO NOT pump flammable fluids, fuels, corrosive chemicals or fluids
containing toxic substances.  These fluids can create potentially
dangerous health and environmental hazards.  Contact local
authorities for assistance.

3.10 Accessories

WACKER offers a complete line of fittings, hoses, and clamps to
properly connect the pump to match various job conditions.
