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.
