Breathing exhaust fumes will cause serious
injury or death! Engine exhaust contains carbon
monoxide, an odorless and deadlygas.
Operate pressure washer in a well-ventilated
area. Avoid enclosed areas such as garages,
basements,etc.
Never operate unit in or near a location occupied
by humans oranimals.
WARNING: Risk of fire, asphyxiation and burning.
Never fill fuel tank when engine is running or hot. Do
not smoke when filling fueltank.
Never fill fuel tank completely. Fill tank to
1/2" (12.7 mm) below bottom of filler neck to
provide space for fuel expansion. Wipe any fuel
spillage from engine and equipment before
startingengine.
DO NOT let hoses come in contact with very hot
engine muffler during or immediately after use
of your pressure washer. Damage to hoses from
contact with hot engine surfaces will NOT be
covered bywarranty.
NOTICE: NEVER pull water supply hose to move
pressure washer. This could damage hose and/or
pumpinlet.
DO NOT use hot water, use cold wateronly.
Never turn water supply off while pressure washer
engine is running or damage to pump willresult.
DO NOT stop spraying water for more than two
minutes at a time. Pump operates in bypass mode
when spray gun trigger is not pressed. When the
temperature inside the pump rises too high the
thermal relief valve (
20
, Fig.J) will open and
release a gush of water in an effort to lower the
temperature inside the pump. The thermal relief
valve will then close. If pump is left in bypass mode
for more than two minutes internal components
of the pump can bedamaged.
