RULES FOR SAFE OPERATION
Before assembling and operating your sprayer, read all instructions
thoroughly. When working with equipment under pressure, safety
precautions must always be carefully observed, including the following:
• NEVER spray flammable materials or pressure and gas producing
chemicals.
•
ALWAYS read chemical label before filling sprayer as some chemicals may
be hazardous when used with this sprayer.
• ALWAYS wear goggles, gloves, a long-sleeve shirt, long pants, and full foot
protection when spraying. Work in a ventilated area or outdoors.
• PRE-USE CHECK: Before each use check tightness of hose nut to be sure hose is
securely attached to the shut-off assembly. Insure hose is securely attached to the tank
by tightening hose clamp if necessary. Insure that all nozzle and wand connections are
tight. Insure the large pump clamp is tight. Insure the 2 bolts used to attach the pump
lever to the pump shaft are tight.
• DO NOT leave a pressurized sprayer in the hot sun or anywhere near a heat source.
Heat can produce pressure to build up causing sprayer to ignite or explode resulting in
injury or death.
• NEVER pressurize sprayer by any means other than the original pump. Over
pressurizing can cause sprayer to explode resulting in injury or death.
• DO NOT attempt to modify or repair this product except with original manufacturer’s
parts.
NOTE: The tank and hose may have residual water in it due to quality
testing performed on the sprayer.

APPLICATIONS & USE FOR YOUR SPRAYER
Avoid using a sprayer for general cleaning purposes if plant protection or herbicide chemicals
have already been used in the sprayer. If a sprayer has been used for plant protection or as an
herbicide, clean the sprayer completely (see cleaning section) before using.
Plant Food
: Use different spray patterns for optimum foliage feeding or for fungicide and
pesticide application.
Herbicides: Reduce weeds and unwanted plants but avoid using the same sprayer for plant
feeding or protection without thoroughly cleaning (see cleaning section) the sprayer first.
General Household Use: Apply detergents, vinegar, cleaning solutions, warm water (do not
exceed 120°F/49°C) or nontoxic household cleaning chemicals for carpets, floors, walls, glass,
counter tops and ceilings. DO NOT use sprayer that has been used with herbicides, pesticides or
other toxic chemicals for household applications.
General Outdoor Use: Use the sprayer for cleaning windows or with a detergent for general
purpose cleaning. Other applications include wood preservatives, waxes, water proofing, and
