BEFORE STARTING THE ENGINE
Before you operate your pressure washer, you should prepare
the engine for the initial starting. To operate the engine you
will need the following:
EH ENGINE OIL
IMPORTANT: Any attemp to crank or start the engine before
it has been properly serviced with the recommended oil may
result in an engine failure.
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF,SG or SH, rated SAE 30 weight. Select
the oil's viscosity grade according to your expected
operating temperature.
Although multi-viscosity oils (5W30, 10W30, etc.) improve
starting in cold weather, these multi-viscosity oils will result in
increased oil consumption when used above 32°F. Check
your engine oil level more frequently to avoid possible damage
from running low on oil. Oil sump capacity is 20 ounces.
* Place pressure washer on a level surface.
es Clean area around oil fill and remove oil dipstick (Step 8)
STEP 8 — Add oil to engine crankcase. Do not
attempt to start engine without adding oil. .
* Wipe dipstick clean. Pour oil into oil fill opening until oil
reaches FULL mark on the dipstick. Stop occasionally to
check oil level. DO NOT OVERFILL.
* Install oil dipstick, hand tighten securely.

3. Simply shutting OFF engine will not release pressure in the
system. When engine has shut down, squeeze the trigger
on the gun to relieve the pressure in the hose.
Ш NOZZLE MAINTENANCE
If the adjustable nozzle becomes restricted or clogged with
foreign materials, such as dirt, excessive pump pressure may
develop. If this nozzle becomes partially clogged, it can cause
a pulsing sensation during use. This generally is not a pump
related problem, but rather a clogged or partially restricted
adjustable nozzle.
If the adjustable nozzle becomes clogged or partially restricted,
immediately clean the nozzle with the kit included with your
pressure washer by following these instructions:
* Shut off the engine and turn off the water supply.
* Separate the wand extension from the gun.
* Adjust the wand extension to the stream position.
* Remove nozzle from the end of the wand extension (Figure
18) using a 2mm or 5/64 allen wrench (like the one included
inthe kit). —
* Use the wire included in the kit (Figure 18) or a small paper
clip to free the foreign materials clogging or restricting the
nozzle.
FIGURE 18 Removing and cleaning nozzle. -
* Remove additional debris by back flushing water supply
through wand extension (Fig.19). Back flush between 30 to
60 seconds. Turn wand extension to stream spray and move
nozzle from low to high while flushing.
~~ FIGURE19 — Backflushing the nozzle. .; -
* Reinstall nozzle into the wand extension. DO NOT over
tighten.
* Reconnect the wand extension to the gun.
» Reconnect the water supply, turn on the water, and start the
engine.
* Test the pressure washer by operating with nozzle in the high
and in the low position.

PREPARING THE UNIT FOR
STORAGE
Water should not remain in the unit for long periods of time.
Sediments of minerals can deposit on pump parts and “freeze”
pump action. If you do not plan to use the pressure washer
for more than 30 days, follow this procedure:
1. Flush detergent hose by placing the injector filter into a pail
of clean water while running pressure washer with nozzle
in low pressure mode. Flush for five minutes.
2. Shut off the engine and let it cool, then remove all hoses.
3. Place throttle lever in STOP position.
A
CAUTION: Be sure lever is in “STOP” position
before you continue. If you start engine without
proper water supply connected, you can damage
pump.
4. Empty the pump of all pumped liquids by pulling recoil
handie about 6 times. This should remove most of the
liquid in the pump.
NOTE: To protect unit from freezing temperatures, draw wind-
shield washer fluid into pump by pouring windshield washer
fluid into a 3-foot section of garden hose connected to inlet
adaptor and pulling recoil handle twice.
5. Store in a clean, dry area.
H ENGINE PREPARATION
A WARNING: NEVER STORE ENGINE WITH FUEL IN
TANK INDOORS OR IN ENCLOSED, POORLY VEN-
TILATED AREAS WHERE FUMES MAY REACH AN
OPEN FLAME, SPARK OR PILOT LIGHT AS ON A
FURNACE, WATER HEATER, CLOTHES DRYER OR
OTHER GAS APPLIANCE.
The engine manufacturer recommends using Briggs & Strat-
ton Gasoline Additive (Part No. 5041), available from any
Generac Authorized Dealer. Mix additive with fuel in fuel tank
or storage container. Run engine for short time to circulate
additive through carburetor. Engine and fuel can be stored
for up to 24 months. |
NOTE: If you did use “gasoho!”, run engine until engine stops
from lack of fuel.
Change Oil: While engine 1s still warm, drain oil from
crankcase. Refill with recommended grade.
Oil Cylinder Bore: Remove spark plug and pour about 1/2
ounce (15ml) of engine oil into the cylinder. Cover spark plug
hole with rag. Crank slowly to distribute oil. |
A
Install spark plug. Do not connect spark plug wire.
CAUTION! Avoid spray from spark plug hole when
cranking engine slowly.
