Pressure washers are useful cleaning tools designed to
clean almost any surface in two easy steps.
• The !irs.t step involves applying an appropriate deter-
gem/solyent solution to penetrate anu loosen grime:
The oetergent is applied at low pressure to avoia
splashing, overspraying and waste° Leave the solution
on the surface for 3 to 5 minutes to allow the solution
to work°
• The second step involves cleaning the surface you
have prepared with the pressure washer and then
rinsing it clean.
To apply detergent follow these steps:
° P!epare your detergent solution as required by your'
IOD,,
° Place the small filter of
the clear', detergent
syphoning tube into the
detergenfcontainer (Fig

BEFORE STARTING THE ENGINE
To operate the engine you will need the following:
ENGINE OIL
IMPORTANT: ANY ATTEMPT TO CRANK OR START
THE ENGINE BEFORE IT HAS BEEN PROPERLY SER-
VICED WITH THE RECOMMENDED OIL RESULTS tNAN
ENGINE FAILURE,
A 20 oz. bottle of SAE 30 weight oil is included in the parts
carton.
NOTE: When adding oil to the engine crankcase in the
future, use only high quality detergent oil rated with APt
service classification SF or SG, rated SAE 30 weight.
Select the oil's viscosity grade according to your expected
operating temperature.
colder = 32°F - warmer
5W30 i SAE30
Although multi-viscosity oils (5W30, 10W30, etcr)improve
starting in cold weather, these multi-viscosity oils will result
in increased .oil consumption when used above 32°F.
Check your e6gine oil level more frequently to avoid possi-
ble damage from running low on oil. Oil sump capacity is
20 ounces.
• Position pressure washer so engine is level
• Clean area around oil fill and remove oi! dipstick (Fig.
13).
, Wipe dipstick clean, insert it into oil fill hole and tighten
securely.. Remove oil dipstick. If oil is not up to FULL
MARK on dipstick, add recommended oil. POUR
SLOWLY.

Water
SIPHONING
We do not recommend that you siphon your water supply
from sources other than from connecting to household
water supply for the following reasons:
• The pump's lifting capability is only a 3-foot maximum
vertical heighL
• You need an extra intake water filter'
• You need to use a rigid intake hose (it cannot co!lapse)_
° intake water cannot contain any mixture of detergent
or chemicals_ This could affect the life of the pumF
TIPS
• Initially clean an area and then check the surface for
damage, if no damage is found, you can assume it is
okay to continue cleaning. Detergents work best when
applied to dry surface.
° For most effective cleaning, keep spray nozzle be-
tween 8 to 24 inches of cleaning surface..
• Allow the detergent to soak in between 3-5 minutes
before washing and rinsing.
• For' cleaning, start at lower-portion of area to be washed
and work upward, using long, even overlapping
strokes.
° For rinsing, push the nozzle sleeve to high pressure
and wait for detergent to clear. Start at the top of area
to be rinsed, working down with the same action as for'
cleaning.
° Never use the garden hose inlet to siphon detergent or
wax.
° If you get the spray nozzle too close, especially using
high pressure mode, you may damage the cleaning
surface.
° Ifyou have the spray nozzle too fat away, the cleaning
will not be as effective.
• Do not get closer than 6 inches when cleaning automo-
bile tires.
