SAFETY PRECAUTIONS

• Read owner’s manual completely before operating this sprayer.
• Always use goggles, gloves, and protective clothing when using sprayer.
• Read and follow all instructions and cautions on label of products used in this sprayer.
• Never use flammable liquids, caustics, acids, or hot water in this tank.
• Do not leave sprayer in the sun when not in use.
• Spray when air is calm to prevent drift of chemicals.
• Do not use sprayer near open flame or anything that could cause ignition of the spray.
• Always inspect hose and all hose connections before each use. A damaged hose, or loose hose connection can result in unintended exposure to the pressurized chemical, resulting in serious injury or property damage.
• Do not lift or carry sprayer by the hose, shut-off valve, or wand extension. Carry by the handle only.
• Do not pressurize with any mechanical device such as an air compressor, since this can create a dangerous pressure level and bursting of parts resulting in serious injury. Only use original pump.
• Do not store chemicals in this tank.
• Always release pressure when sprayer is not in use and before performing any maintenance.
• Clean and rinse sprayer thoroughly after each use.
• Never attempt to alter sprayer from original condition.
• Always use replacement parts from original manufacturer.
• Keep the sprayer and all chemicals out of the reach of children.

WARNING
ALWAYS CLEAN THE SPRAYER AND SHUT-OFF THOROUGHLY AFTER EACH USE OR WHEN CHANGING APPLICATIONS AS DESCRIBED IN THE CLEANING SECTION. FAILURE TO COMPLETELY CLEAN MAY CAUSE CROSS-CONTAMINATION.

CAUTION
Always empty, clean and dry tank, pump system, shut-off, hose, and extension after each use. FAILURE TO DO SO MAY WEAKEN SPRAYER COMPONENTS, CAUSING COMPONENTS TO RUPTURE WHEN PRESSURIZED. Additionally, FAILURE TO CLEAN AND PROPERLY MAINTAIN YOUR SPRAYER WILL VOID MANUFACTURER’S WARRANTY.

WARNING
The sprayer is operated with liquid under pressure. Failure to observe caution and to follow instructions for operating and cleaning can cause tank, hose and other parts to be weakened and rupture under pressure. This can result in serious injury from high pressure discharge of liquids or forcible ejection of parts. Do not use flammable materials in this sprayer. Material could ignite or explode, causing serious injury and/or possible death. For safe use of this product, you must read and follow all instructions before use.

TEST SPRAYER WITH WATER BEFORE USING ANY CHEMICALS.
