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 considered the  
break-in period. Be sure to follow the maintenance  
schedule on Page 16 after 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 8. Water pressure adjustment knob.  
REDUCE ENGINE SPEED. Slowing the  
engine will reduce the pressure created by  
the pump.  
Adjusting Pressure  
NOTICE  
DO NOT attempt to increase the maximum  
pump pressure by modifying controls or  
otherwise altering the machine. A higher  
pressure setting than the factory set  
maximum pressure may damage the pump  
or cause components to fail, resulting in  
serious personal injury.  
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.  
The pressure setting on the Model H8191 was  
preset at the factory to achieve optimum pressure  
for general purpose cleaning.  
Changing Nozzles  
To adjust the pressure:  
BACK AWAY FROM THE SURFACE TO BE  
CLEANED. Moving further away reduces the  
pressure on the workpiece.  
The Model H8191 pressure washer is equipped  
with five spray nozzles housed in receptacles on  
the front panel. Each nozzle is color coded and  
delivers a specific spray pattern for a particular  
cleaning purpose. The 0°, 15°, 25°, and 40°  
nozzles are high pressure nozzles; the chemical  
nozzle is a low pressure nozzle.  
SELECT A DIFFERENT NOZZLE. Nozzles  
with a wider angled spray deliver a less  
powerful stream.  
ADJUST THE PRESSURE REGULATOR  
ON THE PUMP. Turn the water pressure  
adjustment knob counterclockwise to lower  
the pressure (Figure 8). Once you have  
finished using your pressure washer, return  
the regulator to its original position by turning  
it clockwise.

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 9. Inserting a nozzle.  
4. Release the quick connect coupler, then twist  
and pull the 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 or equipment damage.  
NOTICE  
Applying chemicals or cleaning solvents  
is a low pressure operation. Use only the  
chemical nozzle to apply chemicals or  
solvents.  
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.

3. Connect the low pressure chemical nozzle to  
the spray gun as described on Page 12.  
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 using chemicals or cleaning solutions,  
draw clean water through the chemical hose  
and pressure washer to rinse the internal  
components.  
To apply chemicals:  
Drawing Water from  
Standing Water  
Source  
1. Push the chemical hose onto the barbed  
fitting located near the pump output port, as  
shown in Figure 10.  
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 that 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 10. Chemical hose attached to barbed  
fitting.  
2. Push the other end of the chemical hose onto  
the chemical hose filter (Figure 11), and fully
