Risk of Electric Shock - This pump has not been
investigated for use in swimming pool or marine areas.
CAUTION
DO NOT restrict the fl ow of the discharge hose as it may
cause the pump to overheat.
Be careful of discharge hose whipping under pressure.
ALWAYS check pump oil level only when pump is cool.
Expansion due to heat may cause hot oil to spray from
the oil plug when the oil plug is removed. The possibility
of severe scalding may exist.
NOTICE
ALWAYS place the pump in an upright position on a
platform before using. The platform will prevent the pump
from burrowing itself on soft sand or mud.
