Keep good footing and balance at all times.
18. Do not operate this machine when fatigued or
under the influence of alcohol, prescription medica-
tions, or drugs.
19. Follow the maintenance instructions specified in
the manual.
WARNING: Use vapor fuel only.
20. The LP models are designed to run on vapor
propane fuel. Do not use liquid fuel. Have a
qualified serviceman install and service your equip-
ment.
21. Neverexpose a spark or flame where there may be
unburned gas present.
22. Install this machine about 2 feet from wall to
provide adequate ventilation and servicing space.
This equipment incorporates parts such as snap
switches or similar parts that tend to produce arcs
or sparks. Therefore, when located in a garage, it
should be in a room or enclosure provided for the
purpose or should be installed 18" (457mm) or
more above the floor.
WARNING: To reduce the risk of electric shock,
disconnect all electrical connections and shut-off
gas valve before servicing.
23. Install this machine on non combustible flooring.
24. Exhaust gases should not be vented into a wall, a
ceiling or a concealed space of a building. A draft
diverter must be installed to prevent down draft and
to allow cooling of exhaust temperatures. Down
draft diverters shall be installed in the vents and
located at a distance from the pressure washer
stack to achieve maximum draft of 36" minimum.
Exhaust gases that exceed 470°F (243°C) are not
suitable for connection to Type B gas vents.

Machines
WARNING: Do not spray machine
or any people, animals or elec-
trical parts.
Follow the maintenance instructions
specified in the manual.

Propane Tank Safety Instructions
CAUTION: Only qualified persons should fill your
LP-gas containers.
1. Never allow your LP-gas container to be filled
above the maximum safe level as indicated by a
scale or the fixed liquid level gauge (outage). Do
not use the visible gauge for filling.
2. Do not use a wrench or pliers to close the service
valve or fixed liquid level gauge. These valves are
designed to be closed leak-tight by hand or screw-
driver as appropriate. If wrenches are necessary to
stop a leak, the valve needs repair or replacement.
3. When tightening the POL Nut (left hand thread) on
the service valve, draw it up snug with a proper
wrench. This is a machined male brass fitting
which seats securely against a female seat in the
POL valve – no pipe dope is necessary. Acme/
Type 1 valves have right handed threads which are
secure when hand tight, and on the Quick Discon-
nect/Type 2 Valves, the male connection is
inserted into the female connection on the cylinder
valve. (No wrenches required for both the Acme
and the Quick Disconnect.)
4. When using container, slowly open service valve
all the way. Listen to the regulator. A continuous
hiss may indicate a leak or an open valve on an
appliance.
5. Check all tank and the line connections periodically
to be sure they are tight. When testing for leaks,
use approved leak detector solution – not matches.
6. Make certain your container is properly fastened in
place.
7. Turn container with open part of container guard
towards frame. This protects valves and regulator
against flying rocks and mud. Transport container
in the proper position in which it is used, with the
valves closed and POL Plugs inserted for POL
Valves or Dust Caps for Acme Valves. Secure the
tank against falling or rolling.
8. Check for leaks after connecting.Apply approved
leak detector solution to connection, turn off all
burners and pilots, and open service valve. Leaks
will be detected by the growth of the bubbles. If
bubbles grow, tighten or repair the connection as
needed. Repeat leak test until problem is
corrected.
9. LP-gas is normally non-corrosive – you need not
worry about the inside of your container. However,
the outside should be kept free from rust by a
periodic coat of paint in a light reflective color. It is
very important to inspect and maintain the bottom
and foot ring on the container.
10. Do not store LP-gas containers indoors or in
enclosed areas. Do not expose LP-gas container
to heat. Always store with service valve closed and
plugged as required.
11. Do not attempt to repair any containers, container
valves, regulator or appliances by yourself. Use
only trained certified LP-gas service personnel to
perform repairs.
