3.3 Before Starting
See Graphic: wc_gr000835
3.3.1 Read safety instructions at the beginning of manual.
3.3.2 Place pump as near to water as possible, on a firm, flat, level surface.
3.3.3 To prime pump, remove prime plug (a) and fill pump case with water.
If the pump case is not filled with water before starting, it will not begin
pumping.
DO NOT open priming plug, discharge plug, or loosen hose fittings if
pump is hot! Water or vapor inside pump may be under pressure.
3.3.4 Check for leaks between pump and engine. If water is leaking, the seal
inside pump is worn or damaged. Continued operation may cause
water damage to engine.
3.3.5 Check that hoses are securely attached to pump. Suction hose (b)
must not have any air leaks. Tighten hose clamps (c) and couplings
(d) . Check that discharge hose (e) is not restricted. Lay hose out as
straight as possible. Remove any twists or sharp bends from hose
which may block the flow of water.
3.3.6 Make sure suction strainer (f) is clean and securely attached to end of
hose. The strainer is designed to protect the pump by preventing large
objects from being pulled into the pump.
NOTICE : Strainer should be positioned so it will remain completely
under water. Running the pump with the strainer above water for long
periods can damage the pump.
3.3.7 Check fuel level, engine oil level, and condition of air cleaner.
