Adding Pump Oi[
Before running the high pressure washer, check the
pump oil level by viewing the sight gtass on the side
of the pump, When properly filled, the oil will be at
the half way point marked by the two triangles. Your
pressure washer pump is shipped with oil, Add oil
only if oil level is lower than the half way point on the
sight glass. Do not overfill, Use 30 weight non-
dete;gent oil if necessary.
,& Warning: Never adjust spray pattern when spray-
ing. Never put hands in front of spray nozzle to
adjust spray pattern because you could be
injured.
Stopping Your Pressure Washer
A CAUTION: Do not run pump without the water
supply connected and turned on. Failure to do so
will result in pump damage.
To turn pressure washer off place the on/stop switch

iMPORTANT: This unit is equipped with a therma;
relief valve, if unit is allowed to run for severaI m;n--
_Jtes without pressing the trigger on the spray gun,
several drops of water may be released through this
valve to cool the unit. The heated water will be pb_rged
from the bottom of the pump.
,& CAUTION: Do Not use engine oil that has been [
shipped with your unit in your pump, Engine oil I
is detergent and your pump uses a non-detergent [
oil. Detergent oil can cause damage to your pump,j
Engine Oil
Your unit has been shipped without oil in the engine.
A bottle of SAE 30 weight oil is included in the carton.
Remove oil plug located on the side of engine. Using a
funnel fill engine crankcase up to the last thread in the
oil port. Pour slowly. Oil reading will be inaccurate on
unlevet ground.
NOTE_ When adding oil to the engine crankcase; use
a high quality detergent oil classified "For Service SF,
SG, SH rated SAE 30 weight. Use no special addi-
tives, Select the oiFs viscosity grade according to
you expected operating temperatures.

BEFORE STARTING THE ENGINE
Tooperate the engine you wilt need to do the following,
A CAUTION: Always check engine oil levei before
every staR. Running engine !ow of oil or out of oil
couId result in serious damage.
A CAUTION: Always check pump oil Ievei before
_, every start, Running pump low on oil couId ,_-esu!t
in pump damage. "
Air cooled engines run hotter than automotive engines.
The use of multi-viscosity oil such as (10W-30, etc.) in
ambient temperatures above 40°F (4°C) will result in
higher than normai oil consumption. If multFviscosity
o]i is used, check the oi_ level more frequentIy to
prevent any posssible engine damage due to lack or
lubrication.
Use of SAE30 oil below 40°F (4°C) will result in hard
starting and possible engine damage dL_eto inad-
equate _ubrication.
Gasoline
Your pressure washer engine is 4 cycle. Use unteaded
fuel only.
CAUTION: Do not overfill the fuel tank. Always
allow room for fuel expansion.
WARNING: Never fitl fuel tank indoors. Never
fill fuet tank when engine is running or hot, Do
not smoke or have open flame when filting fuel
tank.
Connect garden hose to the water inlet on the
pressure washer. Tighten by turning water intet
counterclockwise.
Connect high pressure hose to discharge on pump.
Connect the garden hose to the water spout and turn
water supply on.
Use clean, fresh, regutar unleaded gasoline with a
minimum of 85 octane. Do not mix oil with gasoline.
If unleaded fue_ is not availaMe, _eaded fuel may be
used.
iMPORTANT: It is important to prevent gum deposits
from forming in essentia! fuel system parts such as the
carburetor, fuel filter hose or tank during storage. Also,
experience indicates that alcohol-blended fuels (called
gasohoi or using ethanol or methanol) can attract mois-
ture which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30
days or longer. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may
occur,
NOTE: Never start pressure washer with out water
source turned on and connected to pressure washer.
