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 ammable 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 ame 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-o valve, or extension. Carry by pump handle only,
making sure handle is properly locked in place before lifting.
• 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 removing pump from tank.
• Do not stand with face or body over top of tank when pumping or loosening pump, to prevent pump or
solution from striking you, resulting in serious injury.
• 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
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 ammable materials in this sprayer. Material could ignite or explode, causing seri-
ous 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.
CAUTION
Always empty, clean and dry tank, pump system, shut-o, hose, and extension after each use. FAIL-
URE 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
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.
