IMPORTANT SAFETY WARNINGS (cont.)
FIRE & VENTILATION PRECAUTIONS
- Using a pressure washer indoors CAN KILL YOU IN MINUTES. Engine exhaust contains carbon monoxide.
This is a poison you cannot see or smell. Operate in well ventilated areas ONLY! If the machine is to be
used in an enclosed area, always provide approved vent stacks. Comply with all national, state, and local
codes for locating, venting, and using the machine in enclosed areas. Exhaust fumes contain odorless,
invisible gases which can kill without warning.
- DO NOT operate the machine where flammable vapors, combustible fumes, dust or other combustible
materials may be present.
- DO NOT spray flammable liquids.
- ALWAYS shut down the machine and cool the engine before adding fuel. Refuel in a ventilated area away
from open fires or sparks. DO NOT smoke while refueling. NEVER attempt to refuel while machine is in
operation. Failure to obey this warning can cause an explosion or fire.
- DO NOT overfill the fuel tank. If fuel spillage occurs, do not start the engine before cleaning up and
neutralizing any spilled fuel.
- After shutdown, DO NOT leave the machine unattended until completely cool.
- DO NOT store the unit near an open flame or near any devices that may possibly create sparks.
HIGH PRESSURE SPRAY
- WARNING: RISK OF INJECTION OR SEVERE INJURY TO PERSONS - KEEP CLEAR OF NOZZLE - DO
NOT DIRECT DISCHARGE STREAM AT PERSONS. THIS MACHINE IS TO BE USED ONLY BY
TRAINED OPERATORS.
- Fluids under high pressure spray can be nearly invisible, and can penetrate the skin and cause extremely
serious injury!
- DO NOT discharge spray at yourself, people, animals, machine, plants or any fragile material such as glass.
Personal injury or property damage will occur.
- NEVER allow children or adolescents to operate this equipment. DO NOT operate near children. Keep all
persons at a safe distance when operating the machine.
- ALWAYS wear safety goggles, face protection and protective clothing (including gloves and rubber boots)
when operating the machine to protect yourself from fluid injection, debris, and chemicals.
- NEVER put your hands or fingers over the spray nozzle.
- NEVER use your hands to stop or detect leaks.
- NEVER start the machine until the quick couplers are checked to make sure the sleeves are locked.
- ALWAYS shut off the unit and immediately trigger the gunvalve to relieve any pressure in the system before
removing the cleaning nozzle from the quick coupler uncoupling the pressure hose from the machine, or
before performing any machine service.
- Stay alert - watch what you are doing.
- Know how to stop the product and bleed pressures quickly. Be thoroughly familiar with the controls.
- Do not operate the unit when fatigued or under the influencce of alcohol or drugs.
- ALWAYS hold on firmly to the gun/wand assembly when starting and operating the unit. Failure to do so can
cause the wand to fall and whip dangerously. NEVER operate the gun with the trigger wired in the open
position. To prevent accidental discharge, the trigger gun should be securely locked when not in use.
- NEVER squeeze the trigger unless securely braced. The thrust from the water traveling through the nozzle
may be powerful enough to cause the operator to lost balance if not prepared. DO NOT overreach or stand
on unstable support. Wet surfaces can be slippery, wear protective foot gear and keep good footing and
balance at all times. NEVER trigger the gun while on a ladder or roof.
- DO NOT direct spray on or into electrical installations of any kind! This includes electrical outlets, light bulbs,
fuse boxes, transformers, etc. Severe electrical shock may occur.
- Even after you shut off the unit, there is high pressure water left in the pump, hose and gun until you release
it by triggering the gun. ALWAYS relieve the pressure in the system immediately after shutdown.

Operating Instructions (cont.)
1. Connect discharge hose to machine outlet. (Fig. 2.2-1)
2. If optional low pressure downstream, in-line chemical injector is to be used. Connect the injector at this time
(Fig. 2.2-2). For instructions on connections and use, see in-line chemical injector operating instructions
3. Connect trigger gun to discharge hose with quick coupler (Fig. 2.2-3). DO NOT INSTALL CLEANING
NOZZLE AT THIS TIME. Quick coupler sleeves must be pushed into locked position to prevent acciden-
tal uncoupling (Fig. 2.2-5).
4. Check inlet water filter for blockage then connect water supply hose to machine. Use a 3/4" I.D. or larger
hose with standard 3/4" garden hose fittings. (Fig. 2.2-4)
Incoming water supply must deliver gallons per minute greater than machine capacity.
If questionable, check supply at machine. If supply is insufficient, do not operate from this
outlet. For residental use, the outlet closest to the meter tap will usually deliver the highest
gallons per minute output. DO NOT connect to shallow wells used for lawn sprinkling. Connect
only to clean city water supply or deep domestic well.
Hose Connections (cont.)
The discharge hose supplied with the machine is designed for use on cold water high pressure
cleaners only. Special care, handling and maintenance are required to provide proper and safe
operation. The following guidelines must be followed to ensure safe operation and provide the
maximum hose service life.
- Use only hoses with proper pressure and temperature ratings. NEVER exceed published ratings.
- DO NOT route the hose in a manner that will cause sharp bending, kinking, cutting, abrasion, or
other exterior damage.
- DO NOT pull on the hose to move the machine, untangle knots or use any other excessive pulling
stress.
- DO NOT use the hose if any reinforcement is exposed.
- DO NOT attempt field repairs through an unauthorized hydraulic hose repair shop. Special couplings
and crimping specifications are required for high pressure discharge hose.
- Always examine hose quick couplers and fittings before each operation. If leaking is evident, DO
NOT use.
- NEVER leave discharge hose lying on the floor or ground to be driven over by vehicles or damaged
by falling objects. ALWAYS coil and hang the hose immediately after use. If there is any doubt about
hose condition, replace the hose immediately.

Operating Instructions (cont.)
Before Starting Machine
DO NOT OPERATE GASOLINE AND DIESEL ENGINES IN ENCLOSED AREAS! OPERATE
IN WELL VENTILATED AREAS ONLY!
FIGURE 2.3 - GUNVALVE, EXTENSION, & NOZZLE
1. Locate machine on a level plane.
2. Turn on water supply. There should be no nozzle in the extension at this point.
3. Pull gun trigger, allowing air in system to escape.
4. When water flows in a full steady stream, release gun trigger. (Fig. 2.3)
Starting Gasoline / Diesel Engine Machines
1. Check position of fuel valve, and if closed, open valve. For more detailed information on starting the
machine’s engine, see engine instruction manual.
2. Choke: Close choke on carburetor by moving lever in proper direction. If engine is warm or air tempera-
ture is high, close choke valve half-way, or keep it open fully.
3. BE CERTAIN the gun trigger remains in an open position while starting the engine. Brace yourself as the
gun will kick-back from the high pressure created by the pump once the engine has started.
Machines without APR (Automatic Pressure Relief): If the engine fails to start after 1 or 2 pulls
of the recoil, pressure will build-up in the system. To relieve the pressure squeeze the gunvalve
trigger and allow water to flow freely. There should be NO nozzle or obstruction at the end of
the extension.
4. After engine starts, open choke gradually.
5. Let engine warm up to normal operating temperature.
3. Machines with recoil start: Turn engine ON/OFF switch to the “ON” position. Pull the recoil starter grip
lightly until resistance is felt, then pull briskly.
Reference the IMPORTANT SAFETY WARNINGS section of this manual before operating.
Rapid retraction of starter coil (kickback) will pull hand and arm toward engine faster than you
can let go. Read and understand the engine manual to reduce the risk of injuries.
