ENGINE TECHNICAL iNFORMATION
This is a single cylinder, L-head, air cooled engine. It
is a low emissions engine.
In the State of California, Model Series 90000 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.

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
nozzle clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately
clean the nozzle following these instructions:
1. Shut off engine and turn off water supply.
2. Remove nozzle from end of nozzle extension.
Separate nozzle extension from spray gun. Twist
nozzle clockwise to stream position. Using a 2mm
(5/64) allen wrench, remove orifice from end of
nozzle extension.
I WARNING 1
• 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 gun and make sure it is
secure. Test trigger by pressing it and making sure it
springs back into place when you release it. Engage
safety latch and test trigger. You should not be able to
press trigger. Replace gun immediately if it fails any of
these tests.
Check In-Line Filter
Refer to the illustration and service the in-line filter if it
becomes clogged, as follows:
In-line Filter
Nozzle extension
O-ring
Detach nozzle extension from gun and remove
o-ring and screen from nozzle extension. Flush
screen, gun, and nozzle extension with clean water
to clear debris.
3. Remove in-line filter from other end of nozzle
extension.
4. Use a small paper clip to free any foreign material
clogging or restricting orifice.
Insert wire into orifice and turn back
and forth to clear obstruction.
5. Using a garden hose, remove additional debris by
back flushing water through nozzle extension. Back
flush between 30 to 60 seconds. Turn adjustable
nozzle extension to stream spray and move nozzle
from low to high while flushing.
6. Reinstall orifice and in-line filter into nozzle
extension. DO NOT overtighten orifice with allen
wrench.
7. Reconnect nozzle extension to spray gun.
8. Reconnect water supply, turn on water, and start
engine.
