important USER INFORMATION

spray precautions

Risk of injection or severe cutting injury. If an accident does occur and the spray appears to have pen- etrated the skin, seek emergency medical care. Do not treat as a simple cut. If you are using cleaning agents, be prepared to tell a physician exactly what kind.

•Keep clear of nozzle.

•Do not direct discharge stream at persons or pets.

•Only trained operators should use this product. When operating this unit, basic precautions should always be observed.

•Keep away from the spray. Because of the high pressure and velocity of the spray, fluids can penetrate the skin, causing serious injury.

•Never point the gun at yourself or anyone else. Never put your hand, fingers or body directly over the spray nozzle. Always keep operating area clear of all persons. Use extreme caution when operating near children.

Always wear protective goggles when operating the unit to shield the eyes from flying debris and deter- gents. Other protective equipment such as rubber suits, gloves and respirators are advisable, especially when using cleaning detergents. Use extreme caution when operating near children.

THIS SPARK IGNITION SYSTEM COMPLIES WITH CANADIAN ICES-002.

CE SYSTÈME D’ALLUMAGE PAR ÈTINCELLE EST CONFORME À LA NORME NMB-002 DU CANADA.

•Stay alert-watch what you are doing. Do not operate the unit when fatigued or under the influence of alcohol or drugs.

•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 lose balance if unprepared. 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.

•Caution should be used when directing spray toward fragile materials such as glass. Shattering could result in serious injury.

•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.
