Additional Safety Instructions for Pressure  
Washers  
1. FLUID INJECTION. This machine operates  
at fluid pressures and velocities high  
enough to penetrate human and animal  
flesh. Should such an injury occur, it may  
be a surgical emergency. DO NOT treat  
fluid injection as a normal cut, instead, see  
a physician immediately.  
6. CHANGING NOZZLES. Be sure to release  
water pressure before changing nozzles, or  
performing any service or maintenance, to  
reduce the risk of fluid injection injury.  
7. APPROVED FLUIDS. Some cleaning  
fluids could cause injury to skin, eyes, or  
lungs. Use only cleaning fluids approved  
for high pressure washers and follow the  
manufacturer's recommendations. Never  
spray any corrosive chemicals, poisons,  
insecticides, or flammable solvents with  
this machine.  
2. ADEQUATE VENTILATION. During  
operation this machine produces carbon  
monoxide, which is a poisonous gas. Make  
sure the work area is adequately ventilated.  
Never operate this machine indoors.  
3. COOLING ENGINE. Motor parts get hot  
during operation. Allow to cool before  
placing hands near motor, adding fuel, or  
performing any service or maintenance.  
8. HOLDING SPRAY GUN. The reactive  
force of the spray will cause the gun to  
move, and could cause the operator to  
fall or misdirect the spray. Always stand in  
a stable position, grip the gun firmly with  
both hands, and do not overreach. Use  
extreme caution on roofs and ladders and  
always wear appropriate harnesses and  
safety equipment.  
4. FUEL SPILLS. Fuel exposed to hot engine  
components may ignite. Thoroughly clean  
all fuel spills before starting.  
5. ELECTRICAL OVERSPRAY HAZARD.  
Spraying water near electrical outlets,  
switches, or objects connected to an  
electrical circuit, could result in a fatal  
electric shock.  
9. SLIPPING HAZARDS. The use of pressure  
washers can create puddles and other  
slippery surfaces. Use extreme caution on  
these surfaces to reduce the risk of a fall.  
Like all machinery there is potential danger  
when operating this machine. Accidents are  
frequently caused by lack of familiarity or  
failure to pay attention. Use this machine  
with respect and caution to lessen the  
possibility of operator injury. If normal safety  
precautions are overlooked or ignored,  
serious personal injury may occur.  
No list of safety guidelines can be complete.  
Every shop environment is different. Always  
consider safety first, as it applies to your  
individual working conditions. Use this and  
other machinery with caution and respect.  
Failure to do so could result in serious  
personal injury, damage to equipment, or  
poor work results.

Break-In  
The first 20 hours of operation is condistered the  
break-in period. Be sure to follow the maintainence  
schedule on Page 16 avter 20 hours of use.  
NOTICE  
Failure to follow the break-in maintenance  
schedule can reduce the lifespan of  
the machine and negatively impact  
performance.  
Water Pressure  
Adjustment Knob  
Figure 6. Reducing the pump pressure.  
REDUCE ENGINE SPEED. Slowing the  
engine will reduce the pressure created by  
the pump.  
Adjusting Pressure  
NOTICE  
Engine speed should always be set high  
enough to handle the load of the pump. If  
the engine speed is too low, the motor may  
bog or stop when the spray gun trigger is  
pulled and the pump is activated. Operating  
the engine speed at such a setting can  
cause excessive engine wear and premature  
engine failure.  
DO NOT attempt to increase the pump  
pressure by tampering with controls or  
otherwise altering the machine. A higher  
pressure setting than the factory set pressure  
may damage the pump or cause components  
to fail resulting in serious personal injury.  
The pressure setting on the model H8189/H8190  
was preset at the factory to achieve optimum  
pressure for general purpose cleaning. If you need  
to lower the pressure, it can be accomplished by  
these methods:  
Changing Nozzles  
The model H8189/H8190 pressure washer is  
equipped with five spray nozzles located in  
receptacles on the front panel. Each nozzle is  
color coded and delivers a specific spray pattern  
for a particular cleaning purpose. The size of the  
nozzle determines the shape and pressure of the  
spray. The 0°, 15°, 25°, and 40° nozzles are high  
pressure nozzles; the chemical nozzle is a low  
pressure nozzle.  
BACK AWAY FROM THE SURFACE TO BE  
CLEANED. Moving further away reduces the  
pressure on the workpiece.  
SELECT A DIFFERENT NOZZLE. Nozzles  
with a wider angled spray deliver a less  
powerful stream.  
ADJUST THE PRESSURE REGULATOR  
ON THE PUMP. Turn the pressure regulator  
knob counter-clockwise to lower the pressure  
(Figure 6). Once you have finished using  
your pressure washer, return the regulator to  
its original position by turning it clockwise.  
To change nozzles on the H8189/H8190:  
1. FOLLOW THE SHUTDOWN PROCEDURE  
ON PAGE 14!  
-12-  
H8189/H8190 Gasoline Pressure Washer  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2. Pull the trigger on the spray gun to release  
water pressure. Be sure that all pressurized  
water has been released before removing a  
nozzle.  
Nozzles:  
0° Red Nozzle  
This nozzle delivers an extremely powerful pinpoint  
stream that covers a very small cleaning area.  
3. Pull back the quick connect coupler on the  
end of the spray gun wand and remove the  
current nozzle.  
15° Yellow Nozzle  
This nozzle delivers a powerful 15° spray pattern  
for intense cleaning of small areas.  
4. Select a nozzle and with the quick connect  
coupler on the spray gun wand pulled back,  
insert the nozzle (Figure 7).  
25° Green Nozzle  
This nozzle delivers a 25° spray pattern for intense  
cleaning of larger areas.  
40° White Nozzle  
This nozzle delivers a 40° spray pattern and a  
less powerful stream of water. It covers a wide  
area of cleaning.  
Chemical Black Nozzle  
This nozzle is used to apply chemicals or cleaning  
solutions. It has the least powerful stream.  
Applying Chemicals  
Figure 7. Inserting a nozzle.  
5. Release quick connect coupler and twist  
nozzle to make sure it is secure in the  
coupler.  
Use only household detergents, cleaners, and  
degreasers recommended for use in pressure  
washers. NEVER use toxic or corrosive  
chemicals, acids, poisons, insecticides, or  
flammable solvents such as gasoline or  
kerosene with your pressure washer. Failure  
to follow this warning could result in machine  
failure, significant property damage, severe  
personal injury, or death.  
Always double-check coupler connections on  
all fittings. Improperly connected fittings can  
blow apart under pressure causing severe  
personal injury and/or equipment damage.  
NOTICE  
Always try a nozzle on a small test area or  
piece of test material to determine if it is the  
correct nozzle for the task. Some nozzles  
provide so much pressure they can destroy  
even sturdy materials.  
Applying chemicals or cleaning solvents  
is a low pressure operation. Use only the  
chemical nozzle to apply chemicals or  
solvents.  
-13-

3. Connect the low pressure chemical nozzle to  
the spray gun as described on Page 13.  
NOTICE  
Chemicals left in the pressure washer can  
damage the pump and void the warranty.  
Always rinse the unit thoroughly by running  
clean water through the chemical hose after  
using chemicals or cleaning solvents.  
4. After use of chemicals or cleaning solutions,  
draw clean water through the chemical hose  
and pressure washer to rinse the internal  
components.  
To apply chemicals:  
Standing Water  
Source  
1. Push the chemical hose onto the barbed  
fitting located near the pump water outlet as  
shown in Figure 8.  
To draw water from a standing source:  
1. Attach the supplied input hose filter to the  
input hose and place the input hose filter in  
the standing water source.  
Note: Be sure the water source is free from  
debris which could clog the filter and cause  
a loss of water flow.  
2. Prime the pump by pouring water into the  
other end of the input hose (the end without  
the filter) while the filter end is submerged in  
the water source. Without spilling water out of  
the hose, connect the input hose to the input  
port on the pump.  
Figure 8. The attached chemical hose.  
Note: Be sure the water source is large  
enough to provide 5 GPM of flow for the  
duration of the pressure washer operation.  
2. Push the other end of the chemical hose onto  
the chemical hose filter (Figure 9) and fully  
submerge in a container holding the chemical  
or cleaning solution.  
NOTICE  
If the pump is not able to provide pressurized  
water when drawing from a standing water  
source, shutdown the pressure washer  
immediately and re-attempt to prime the  
pump. Failure to follow this instruction can  
damage the pump and void the warranty.

ladder or doing any work that might accidentally  
discharge the spray gun. To engage the lockout  
lever, simply flip it away from the trigger and clip it  
into the lockout lever groove in the handle (Figure  
10). To release the lever, reverse this procedure  
(Figure 11).  
Operation of this equipment has the potential  
to propel debris into the air which can cause  
eye injury. Always wear safety glasses or  
goggleswhenoperatingequipment. Everyday  
glasses or reading glasses only have impact  
resistant lenses, they are not safety glasses.  
Be certain the safety glasses you wear meet  
the appropriate standards of the American  
National Standards Institute (ANSI).  
To start the H8189/H8190 pressure washer:  
1. Check the engine and pump oil level and fuel  
level (refer to the MAINTENANCE section  
beginning on Page 16 for locations). Add  
engine oil (SAE 30) and/or fuel (unleaded  
gasoline) if necessary.  
2. Securely fasten one end of the provided input  
hose to a threaded hose spigot. Securely  
fasten the other end of the input hose to the  
pump input port.  
Figure 10. The spray gun in the locked position.  
Note: When drawing water from a standing

Shutdown Procedure  
To shut down the pressure washer:  
7. Engage the choke (if cold starting) and set  
the throttle to 34 open.  
1. Release the trigger on the spray gun and  
return the spray gun to the bracket on the  
washer handle.  
8. Squeeze the spray gun trigger until a steady  
stream of water comes out, then release.  
2. Turn the pressure adjustment knob  
counterclockwise until there is no more  
pressure.  
10. Pull the start rope to start the motor.  
Note: For best pull-starting results, pull the  
start rope with forceful, but even pressure to  
spin the motor.  
3. Close the fuel valve.  
4. Switch the motor to the OFF position.  
5. Shut off the water at the spigot, or remove  
the input hose from the water if drawing from  
a standing source. Purge the pressure from  
the system by pulling the spray gun trigger.  
When pull-starting, pull the start rope slowly  
until resistance is felt, then pull with forceful,  
even pressure. Rapidly jerking the start rope  
can cause it to forcefully recoil, potentially  
causing hand and/or arm injury.  
NOTICE  
11. Allow the motor to run long enough to achieve  
normal operating temperature (at least two  
minutes), then set the throttle to the desired  
speed.  
To reduce the risk of damaging engine  
components, DO NOT stop the engine  
abruptly when it is running under load.  
12. Pull the trigger on the spray gun to release  
pressurized water and begin work.  
Note: If the motor does not start after several  
pulls of the start rope, or brief turns of the  
start switch, repeat the starting instructions  
from Step 8. If you are still unable to start the  
motor, refer to the troubleshooting guide on  
Page 20.  
NOTICE  
Never allow the motor to run for more than  
five minutes without pulling the trigger  
on the spray gun to release water. Failure  
to follow this instruction can damage the  
pump and void the warranty.

If there is pronounced coloration, excessive  
corrosion or deposits, or damage to any com-  
ponent of the plug, replace it.  
3. Using a spark plug gap gauge (available at  
most automotive stores), measure the cur-  
rent spark plug gap.  
Note: The gap is the distance between  
the side electrode and the center electrode  
(Figure 22).

Grizzly Industrial, Inc. warrants every product it sells for a period of 1 year to the original purchaser from  
the date of purchase. This warranty does not apply to defects due directly or indirectly to misuse, abuse,  
negligence, accidents, repairs or alterations or lack of maintenance. This is Grizzly’s sole written warranty  
and any and all warranties that may be implied by law, including any merchantability or fitness, for any par-  
ticular purpose, are hereby limited to the duration of this written warranty. We do not warrant or represent  
that the merchandise complies with the provisions of any law or acts unless the manufacturer so warrants.  
In no event shall Grizzly’s liability under this warranty exceed the purchase price paid for the product and  
any legal actions brought against Grizzly shall be tried in the State of Washington, County of Whatcom.  
We shall in no event be liable for death, injuries to persons or property or for incidental, contingent, special,  
or consequential damages arising from the use of our products.  
To take advantage of this warranty, contact us by mail or phone and give us all the details. We will then  
issue you a “Return Number,’’ which must be clearly posted on the outside as well as the inside of the  
carton. We will not accept any item back without this number. Proof of purchase must accompany the  
merchandise.  
The manufacturers reserve the right to change specifications at any time because they constantly strive to  
achieve better quality equipment. We make every effort to ensure that our products meet high quality and  
durability standards and we hope you never need to use this warranty.
