GENERAL SAFETY
1. WARNING –Do not pump flammable or explosive fluids such as gasoline, fuel oil,
kerosene, etc. Do not use in explosive atmospheres. The pump should only be used
with liquids compatible with the pump component materials. Failure to follow this
warning can result in personal injury and/or property damage and will void the product
warranty.
2. Do not run the pump faster than maximum recommended speed.
3. Do not attempt to pump at pressures higher than rated, motor damage may result.
4. Maximum liquid temperature through pump is 140°.
5. Make certain that the power source conforms with the requirements of your equipment
(see cord chart on page 8).
6. Do not operate machine with belt guard, shaft guard or similar safety devices
removed.
7. Prior to servicing, disconnect power, stop engine.
8. Relieve system pressure prior to servicing.
9. Drain all liquids from system before servicing.
10. Secure quick couplers on lines and guns before starting the pump. A loose quick
coupler may cause a hose whip around under pressure causing personal injury and/or
property damage.
11. Check hoses for weak or worn conditions before each use. Make certain that all
connections are tight and secure.
12. Periodically inspect the pump and system components. Perform routine maintenance
as required. See maintenance section in this manual, CAT pump Service Manual and
Honda engine manual as applicable.
13. Electric motors must be adequately grounded.
14. Do not operate a gasoline engine in an enclosed area. Be sure the area is well
ventilated.
15. Gasoline is a highly combustible fuel. The improper use, storage or handling of
gasoline can be dangerous. Never fill or touch a hot engine.
16. Do not handle a pump or motor with wet hands or when standing on a wet or damp
surface.
17. Use only pipe, hose and fittings rated for the maximum P.S.I.G. rating of the pump. If
an unloader is used, use pipe, hose and fittings rated for the pressure at which the
unloader bypass operates.

The U.S. Consumer Product Safety Commission has issued a warning to
consumers who use electrically powered pressure washers for cleaning milk tanks,
spray tanks, and other farm equipment.
According to a federal safety alert, consumers can receive a fatal electrical shock
from pressure washers if the power cord connections become wet or an internal
short exists.
Since pressure washers are used to spray water, the power cord, washer and
consumer are often wet, and this can be fatal, especially if the machine is not
properly grounded, the report explained.
Consumers should not use adaptor plugs to connect the three-wire plug to a two-
prong household receptacle without properly grounding the adaptor plug. Power
cord connections should never be allowed to lie in water.
The commission urges these precautions:
- Always plug a three-wire grounded pressure washer into a properly grounded
receptacle. If possible, use a receptacle protected by a ground fault circuit
interrupter (GFCI).
- Check all flexible cords, plugs and sockets before each use. Replace any
damaged items.
- If an extension cord must be used, use the heavy-duty three-wire, properly
grounded type, and keep the power cord connection out of the water and away from
the item being washed.
- Wear eye protection when using sprayers or pressure washers.
- Wear rubber-soled footwear when operating the washer.
- Never cut or splice the power cord or extension cords.
- Do not leave hoses or cords where they can be run over and damaged.
- Never remove the grounding prong from the power cord plug.
- Never operate the washer after it has tripped a ground fault interrupter or circuit
breaker without first having it examined by a competent repair person.
- Never allow children to operate a pressure washer, and keep them away from the
washer when an adult is using it.
- Never spray the cleaner at yourself or others. The pressure can cause the water
and cleaner to blast under the skin.
- Never start the washer until you have checked to make sure all coupler hose
connections are in place and locked.
FOR MORE INFORMATION, CONSUMERS CAN CALL THE CPSC TOLL-FREE
HOTLINE, 800-638-CPSC.

Check “Quick Couplers” for secure connection: Hose reel to unloader, Return line to tank
& Supply (suction) line on the bottom of the tank.
Open valves: Bypass valve (unloader) & Supply (suction) valve below tank.
Depress spray gun trigger during start-up to allow for “Load Free” run-up.
Check sight glass on filter bowl during start-up. Air bubbles during operation may indicate
a cracked filter bowl or missing o-ring or gasket.
START UP
1. Put 10 gallons of water into the sprayer tank. DO NOT ADD SPRAY YET!!!
TESTS
2. Test the sprayer. It should have up to 800 PSI when spraying with the misting wand.
The bypass valve must be shut for this test.
TANK AGITATION
3. The water in the tank should be agitating whenever the pump is on (but not spraying)
or when the ball valve is open.
LEAK INSPECTION
4. Check for any leaks. Find the source of any and all dripping water. Be sure to
confirm that the filter is clean and that the filter bowl is tightly screwed on.
ADD SPRAY
5. Additional water and spray may now be added to the tank. Any products that are
heavy solids may be added to the tank slowly. Additional water should be added to
the tank to keep the powder well diluted. Some sprays may also be harmful to the
pump seals if used at full strength. Check CAT pump manual for compatibility.
CLEAN UP
6. Cleaning herbicide from the Sprayer: Use one quart of household ammonia per 60
gallons of water (1:240 ratio). Stir well!! Start the pump and run the unit until the
ammonia fills the MD83 hose and wand. Allow to stand for 24 hours.
RINSING
7. Flush with fresh water. Triple rinse with clear water. Winterize for cold weather.

How it Works
First, when you start the GAS-POWERED ENGINE, or ELECTRIC MOTOR, of
your sprayers, the motor drives a crankshaft inside the water pump that starts
the pistons or plungers.
Fresh water, coming in from your fluid supply tank, through the intake hose,
picking up fluid near the bottom of the sprayer tank to the inlet side of the
pump manifold.
The CAT pump produces flow and sends it to the unloader. Pressure is
created by restricting the flow at the nozzle. At a given flow, the smaller the
restriction nozzle the higher the pressure; the larger the restriction nozzle the
lower the pressure.
The unloader acts like a traffic cop, sending the preset amount of flow
through the hose and towards the spray gun and nozzle, and sending the by-
pass fluid back to the pump manifold or through the recirculation hose and
back into the tank (depending on the ball valve position). See page 14 - 16
to learn about the unloader.
Water is pushed through the high pressure hose, through the spray gun that's
controlled by a trigger. The trigger on the spray gun is actually a valve that
controls the flow through the wand. Squeezing the trigger opens the valve,
releasing the trigger closes the valve. The spray gun has a trigger lock
feature that will lock the trigger closed for safety to prevent accidental
activation of the spray gun.
The pump produces flow. The pressure is created by restricting the flow
through the use of an appropriate sized nozzle or tip.
The sizes and flow rate calculations of the nozzles and tips provided with the
Fox sprayer line have been predetermined at the factory. Altering the size and
flow rates of the nozzles and tips can hinder sprayer performance. Wear in a
nozzle or tip can cause pressure drop.
Note: Spray angle does not affect nozzle flow rate.
For twenty-five years, Siebring Manufacturing has been listening to and
incorporating customer suggestions and criticisms to develop a dependable
and user friendly product. The paragraphs below briefly describe the
Siebring “FOX” line of sprayers and how they operate.

35 GALLON TANK COMPONENTS & DESCRIPTIONS
1. Tank Lid –(spin-on lid) vented, allows access to the tank for filling & mixing
and allows air to displace fluid being pumped out.
2. 35 gallon horizontal tank - 29” overall length, 19” in wide & 18.5” high.
Gallon markers on side. Tapered bottom sump for complete fluid pick-up,
draining and cleaning.

This type of unloader may be referred to as a “Trapped Pressure” type or just
"Pressure" type. This type of valve opens to bypass when it senses the pressure
build up of the pump output having nowhere to go. The main characteristic of this
most commonly used valve is how it traps the pressure in the hose when the
trigger of the pressure gun is released and unloading excess pressure between
the pump & unloader.
The disadvantage of this type of valve is the spike of pressure felt by the
operator and sprayer/pressure washer components when the trigger is again
squeezed. This creates a "kickback" effect on the gun/wand so be careful when
using ladders or other types of access equipment. The “kickback” effect is most
noticeable when working with pressures above 1000 PSI. The “Fox” sprayer line
is factory set at 800 PSI for customer comfort and safety.
Pressure Sensitive Regulating Unloader
When your system uses a trigger gun that stops the water flow from the pressure
pump the unloader valve must be employed. Understand that when the trigger of
the gun is released the water flow to the nozzle is interrupted. The power source
and the pressure pump are still running, without some pressure system safety
device the water would have nowhere to go, building pressure until pump
damage occurs.
Enter the Unloader Valve. The most basic function of the unloader is to act as a
"traffic cop" to the water flow in your system as soon as it senses "pressure
build". When the “Pressure Build” condition is met the unloader will then actuate
the piston assembly to divert the water flow toward the bypass port. When this
is occurring the pump is said to be in "bypass mode" and the unloader valve is
said to be "cycling". This scenario ends when the trigger is squeezed alerting
the unloader valve to redirect the flow to the gun and high pressure nozzle once
again.
14
The Siebring sprayers have a ball-valve installed down stream from the pump
and just before the unloader. In the open position, the majority of the by-pass
fluid is directed back to the pump. In the closed position, the majority of the by-
pass fluid is directed to the tank, the remainder circulates through the manifold.
This design constantly supplies cool fluid to the pump & manifold, eliminating
concerns regarding manifold temperatures.
