OPERATING PROCEDURES (cont'd)
Pressure adjustment:
Annovi Reverberi
The pressure setting is preset at the factory to achieve
optimum pressure and cleaning. If you need to lower
the pressure, it can be accomplished by two methods.
The first method is to back away from the surface to
be cleaned. The further away you are, the less the
pressure will be on the surface to be cleaned.
The second method is to adjust the pressure regulator
on the pump. Please read the following instructions
for adjusting the pressure regulator:
Refer to page 16 and 17 to identify the pump that is
on your pressure washer. The pressure is not adjustable on DAPC, Faip, Karcher, or smaller Giant pumps.
General
The Annovi Reverberi, Cat, General and larger Giant
pumps pressure can be lowered by turning the
pressure regulator counterclockwise. Refer to the
illustrations to the right to identify your pressure
regulator.
Once you have finished using your pressure washer,
return the pressure regulator to its original position by
turning it clockwise.
DO NOT attempt to increase pump pressure. A higher pressure setting than the
factory set pressure will damage pump.

OPERATING PROCEDURES (cont'd)
Chemical Flow Adjustment
Some pumps are equipped with an adjustable chemical injector as shown here. Turn the chemical adjustment knob counterclockwise to increase the amount
of chemical used and clockwise to decrease the
amount of chemical used. If the knob is turned
clockwise until it stops, the chemical injector will close
and will not draw any chemicals/soaps.
DO NOT allow your unit to operate in
bypass mode for more than two minutes at
any time. Overheating of pump will cause
damage to pump.
Thermal Relief Valve
Chemical Adjustment
or
or
Shut Down Procedure:
Thermal Relief Valve:
During normal operation, the water from your cold
water supply circulates inside the pressure washer
pump allowing the pump to maintain a desired operating temperature. When you stop spraying water
through your wand/lance and the engine is still running, this is considered the by-pass mode.
When the unit is in the by-pass mode, the water
circulation inside the pump begins to heat up. If the
unit is left in the by-pass mode for more than two (2)
minutes, the water temperature will rise to a dangerous level and damage the internal components of the
pump.
In an effort to prevent damage, pumps are equipped
with a thermal relief valve. This valve will open when
the temperature rises too high. This valve will then
release a gush of water in an effort to lower the
temperature inside the pump. Immediately after this
occurs, the valve will close.
15 — ENG
1. If you have siphoned chemicals, siphon a bucket
of clean water through the chemical hose. NOTE:
Failure to do so will cause damage to the pump.
2. Turn engine off. See Engine Owner’s Manual.
NOTE: NEVER turn the water off with the
engine running.
3. Turn water source off.
4. See Storage section in this manual for proper
storage procedures.
Turn off Water
MAINTENANCE
WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED TO HOT SURFACES, WATER PRESSURE, MOVING PARTS, OR
FIRE RESULTING IN DEATH. BEFORE PERFORMING ANY MAINTENANCE OR REPAIR, DISCONNECT SPARK PLUG WIRE,
LET ENGINE COOL AND RELEASE ALL WATER PRESSURE. THE ENGINE CONTAINS FLAMMABLE FUEL. DO NOT SMOKE
OR WORK NEAR OPEN FLAMES WHILE PERFORMING MAINTENANCE.
To ensure efficient operation and longer life of your pressure washer, a routine maintenance schedule should be
prepared and followed. The following routine maintenance schedule is geared to an unit in a normal working
environment. If necessary, the schedule should be modified to suit the conditions under which your pressure washer
is used. The modifications will depend upon the hours of operation and the working environment. If the pressure
washer is in an extremely dirty and/or hostile environment it will require a greater frequency of all maintenance checks.
1. Consult the Engine Owners Manual for the
manufacturer's recommendations for any and all
maintenance.

STORAGE & WINTER STORAGE
PREPARATION FOR STORAGE
It is recommended that you follow these steps to
protect the internal seals of the pressure washer when
storing the unit for an extended period and WHEN
FREEZING TEMPERATURES ARE EXPECTED.
ENGINE
1. Remove gasoline from engine or add fuel stabilizer, such as "Sta-Bil" to gasoline to prevent
gumming
2. If you are adding fuel stabilizer, connect water
supply and high pressure hose to pump and spray
gun.
1. Obtain a funnel, six ounces of RV antifreeze, and
approximately 12 inches of garden hose with a
male hose connector attached to one end.
Use only RV antifreeze. Any other antifreeze
is corrosive and can damage pump.
2. Disconnect spark plug wire.
3. Disconnect high pressure hose from pump and
from spray gun.
4. Connect 12 inch length of hose to water inlet of
pump.
5. Add RV antifreeze to hose as shown.
3. Turn water supply on and start engine.
4. Squeeze spray gun trigger while engine is running
to avoid operating the pump in ""bypass mode"".
5.
Run engine for five minutes, then shut engine off.
6.
Disconnect water supply.
7. Disconnect spark plug wire and remove spark
plug.
8. Pour one teaspoon of engine oil into spark plug
hole.
9. Place a rag over spark plug hole and pull starter
rope slowly several times to lubricate internal
cylinder wall.
PUMP
NOTE: If storing the unit for more than 30 days RV
antifreeze needs to be ran through the pump. This
helps prevent damage within the pump head. RV
antifreeze is not only added for winterizing, but for
proper lubrication regardless of temperature or
environment. Storing the pump less than 30 days
does not require the RV antifreeze.
6. Pull engine starter rope slowly several times until
antifreeze comes out of high pressure hose
connection of pump.
7. Remove short hose from water inlet of pump.
8. Install spark plug into spark plug hole and tighten
securely, then reconnect spark plug wire.
9. Drain all water from high pressure hose, coil it, and
store it in cradle of the pressure washer handle.
10. Drain all water from spray gun and wand by
holding spray gun in a vertical position with nozzle
end pointing down and squeezing trigger. Store in
gun/hose holder.
11. Store chemical hose, high pressure hose, spray
gun, and wand so they are protected from damage, such as being run over.
