WARNINGS
•This sprayer is designed and manufactured solely for the purpose of applying
agricultural chemicals. Under no circumstances may it be used for any other purpose.
•Read owner’s manual completely before operating this sprayer.
•Test the sprayer with water before using chemicals
•Before using chemicals refer to the chemical manufacturer’s label and safety
instructions for safe handling procedures and the recommended personal protective
clothing and safety equipment.
•Spray when air is calm to prevent drift of chemicals.
•Always release pressure when sprayer is not in use and before performing any
maintenance.
•Do not leave sprayer in the sun when not in use.
•Never use flammable liquids, caustics, acids, or hot water in this tank.
•Do not use sprayer near open flame or anything that could cause ignition of the spray.
•Always inspect the hose and all hose connections before each use. A damaged hose, or
loose hose connection can result in unintended exposure to the pressurised chemical,
resulting in serious injury or property damage.
•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 lift or carry sprayer by the hose, shut-off valve, or wand extension. Carry by the
handle only.
•Do not store chemicals in this tank.
•Clean and rinse sprayer thoroughly after each use and before and maintenance.
•Never attempt to alter sprayer from original condition.
•Exercise care to ensure proper stability when carrying or operating in hilly or uneven
terrain, particularly if the ground is wet or loose. Wear non-slip shoes
•Keep the sprayer and all chemicals out of the reach of children.

Assemble Extension, Shut-Off, Nozzle and Spray Optimizer:
1. Install the extension “wand” onto the shut-
off assembly and tighten the nut securely.
(See Figure A)
2. Install Spray Optimiser for low pressure (low
drift) applications. This will help prevent
weed killer formulas from drifting into
undesired areas. (Do not over tighten,
actual position will vary. See Figure B)
3. Install selected nozzle onto the end of the
extension or optimiser (if installed) and
tighten securely (See Figure C)

desired level.
4. Reinstall the cap.
Pressurising and Spraying:
1. To begin pressurising, be sure the spray gun shut-off lever is not on. Pump handle up
and down in a smooth motion (See Figure E). Operating pressure is reached when
pumping becomes difficult, which is no more than5-7 full pumps. (Do not over-
pressurise)
2. Direct nozzle away from you and squeeze shut-off lever to begin spraying.
3. To maintain pressure while spraying, operate pump handle every 8 sec. or as needed.
4. For continuous spraying, squeeze lever and rotate lock. (See Figure F)
5. Unlock if needed and release shut-off lever to stop spraying.

Cleaning:
1. Fill the tank with clean tap water. Replace the cap and tighten securely. (Never use hot
water for cleaning)
2. Agitate the tank to rinse the chemical from the tank walls.
3. Remove the cap and empty the contents into gravel or bare soil.
4. Refill the tank with clean tap water. Replace the cap and tighten securely.
5. Pressurise the tank as described in the Pressurising and Spraying section.
6. Direct the nozzle away from you and activate the shut-off for at least 30 seconds to
clean the pressure chamber, hose and shut-off.
7. Remove the cap and empty the contents into gravel or bare soil.
8. Repeat steps 4 - 7 until thoroughly cleaned. Remove nozzle when flushing pump system.
Clean nozzle before replacing.
