INSTALLATION
MAINTENANCE
If the pressure washer is to be used in an enclosed area,
a flue must be installed to vent engine exhaust to the
outside atmosphere. Poor draft will cause the pressure
washer not operate properly.
When selecting the location for installation, beware of
poorly ventilated locations or areas where exhaust fans
may cause an insufficient supply of oxygen.
Proper combustion can only be obtained when there is
a sufficient supply of oxygen available for the amount of
fuel being burned. If it is necessary to install the machine
in a poorly ventilated area, outside fresh air will have to
be supplied to the machine.
Locate the pressure washer so that the flue will be as
straight as possible and protrude through the roof at a
proper height and location to provide adequate draft.
This oil fired pressure washer must have a draft regu-
lator installed in the flue (available from most heating
contractors). A draft regulator will permit proper upward
flow of exhaust flue gases.
WATER SUPPLY
Your water supply must provide water to the equipment
that exceeds the Gallon Per Minute (GPM) rate of your
machine. You can check your GPM by using a 5 gallon
bucket and a timer. If your machine is 5 GPM or less
and the bucket fills in less than a minute you have ad-
equate supply. Some water supply systems are affected
by things like washing machines, livestock watering
systems and flushing of toilets. Be sure the supply is
still adequate when these operations are taking place.
The water temperature cannon exceed 145 Degrees
Fahrenheit on the standard models and 180 degrees
Fahrenheit on the high temperature models and the
pressure should not exceed 60 PSI. Failure to secure
adequate water supply to your commercial pressure
washer will result in pump damage.
¡DO NOT RUN PUMP DRY!
PUMP
DO NOT:
1. Pump acids.
2. Fail to winterize in freezing temperatures.
3. Allow pump to run dry.
4. Allow machine to run with trigger gun closed for
more than 3 minutes at any one time or damage
to pump may occur.
BEFORE STARTING
Connect the water supply hose to the water inlet (stan-
dard garden hose connector). The water faucet and
supply hose must be capable of providing (GPM) rate
of your machine.
DO:
1. Use a water softener on the water system if
known to be high in mineral content.
2. Use only high quality detergents and follow
manufacturer's mix recommendations.
3. Immediately after using detergent solutions the
system should be flushed thoroughly with clear
water.
4. Clean strainer screen on detergent line
periodically.
Recommendation to lift the machine.
Do not lift the machine. Refer to image. Can cause
damage to the gas tank.
