ENGINE TECHNICAL INFORMATION
This is a single cylinder, overhead valve (OHV), air
cooled engine. It is a low emissions engine.
In the State of California, Model Series 120000
engines are certified by the California Air Resources
Board to meet emissions standards for 125 hours.
Such certification does not grant the purchaser, owner
or operator of this engine any additional warranties
with respect to the performance or operational life of
this engine. The engine is warranted solely according
to the product and emissions warranties stated
elsewhere in this manual.
Power Ratings
* The power ratings for an individual engine model are
initially developed by starting with SAE (Society of
Automotive Engineers) code J1940 (Small Engine
Power & Torque Rating Procedure) (Revision 2002-
05). Given both the wide array of products on which
our engines are placed, and the variety of
environmental issues applicable to operating the
equipment, it may be that the engine you have
purchased will not develop the rated horsepower when
used in a piece of power equipment (actual "on-site"
power). This difference is due to a variety of factors
including, but not limited to, the following: differences
in altitude, temperature, barometric pressure, humidity,
fuel, engine lubrication, maximum governed engine
speed, individual engine to engine variability, design of
the particular piece of power equipment, the manner in
which the engine is operated, engine run-in to reduce
friction and clean out of combustion chambers,
adjustments to the valves and carburetor, and other
factors. The power ratings may also be adjusted
based on comparisons to other similar engines utilized
in similar applications, and will therefore not
necessarily match the values derived using the
foregoing codes.

CAUTION
Check In-Line Filter
Refer to the illustration and service the in-line filter if it
becomes clogged, as follows:
• DO NOT insert any objects through cooling slots.
• Use a damp cloth to wipe exterior surfaces clean.
• Use a soft bristle brush to loosen caked on dirt, oil,
etc.
• Use a vacuum cleaner to pick up loose dirt and debris.
• Use low pressure air (not to exceed 25 psi) to blow
away dirt. Inspect cooling air slots and openings on
the pressure washer. These openings must be kept
clean and unobstructed.
Check and Clean Inlet Screen
Examine garden hose inlet screen. Clean if it is
clogged or replace if it is torn.
Check High Pressure Hose
High pressure hoses can develop leaks from wear,
kinking, or abuse. Inspect hose before each use.
Check for cuts, leaks, abrasions, bulging of cover, or
damage or movement of couplings. If any of these
conditions exist, replace hose immediately.
i WARNING i
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum
pressure rating of unit.
Check Gun and Nozzle Extension
Examine hose connection to spray gun and make sure
it is secure. Test trigger by pressing it and making
sure it springs back into place when you release it. Put
trigger lock in UP position and test trigger. You should
not be able to press trigger. Replace spray gun
immediately if it fails any of these tests.

against in-line filter screen.
4. Assemble nozzle extension to spray gun, as
described earlier in manual.
Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.
The principal cause of excessive pump pressure is a
spray tip clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately
clean the spray tip following these instructions:
1. Shut off engine and turn off water supply.
2. Remove spray tip from end of nozzle extension.
3. Remove in-line filter from other end of nozzle
extension.
,
Use a small paper clip to free any foreign material
clogging or restricting spray tip.
Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if
clogged. The tube should fit tightly on the barbed
fitting. Examine the tube for leaks or tears. Replace
the filter or tube if either is damaged.

Oil
Oil Recommendations
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF, SG, SH, SJ or higher. DO NOT use
special additives.
Choose a viscosity according to the following table:
]
'F _0 ,t , 2? 3_ 4? . 10 . _0 . _:
°C 30 20 10 0 /0 20 30 40
STARTING TEMPERATURE RANGE ANTIC{PATED BEFORE NEXT OIL CHANGE
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with "SJ/CF
ENERGY CONSERVING" or higher, is an acceptable
oil at all temperatures. Use of synthetic oil does not
alter required oil change intervals.
* The use of multi-viscosity oils (5W-30, 10W-30, etc.)
in temperatures above 40°F (4°C) will result in higher
than normal oil consumption. When using a multi-
viscosity oil, check oil more frequently.
** If using SAE 30 oil in temperatures below 40°F
(4°C), it will result in hard starting and possible engine
bore damage due to inadequate lubrication.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 5 hours of operation. Keep oil level maintained.
1. Make sure pressure washer is on a level surface.
2. Remove oil dipstick and wipe dipstick with clean
cloth. Replace and tighten dipstick. Remove and
and check oil level.
3. Verify oil is at "Full" mark on dipstick. Replace and
tighten dipstick.
Adding Engine Oil
1. Make sure pressure washer is on a level surface.
2. Check oil level as described in "Checking Oil Level".
3. If needed, slowly pour oil into oil fill opening to the
"Full" mark on dipstick. DO NOT overfill.
4. Replace and tighten dipstick.
