3 Basic operation
3.1 Prep
1. Install the round metallic knob on the motor speed dial next to the power
switch.
2. Make sure there is a green O-ring between nozzle and wand, and another
green O-ring between the wand and handle.
3. Charge the battery. (Power adapter light is Red when charging and Green
when charged.)
4. Open tank lid. Pour your solution through the provided under-lid filter
(otherwise debris can damage the pump). Then tighten the lid.
5. Insert strap connectors into slots on the sides. Lock the straps by pulling
up until you hear a click.
6. Put on the backpack.
3.2 Spraying
1. Press |on the power switch.
2. To spray, hold the trigger on the handle.
3. To spray without having to hold the trigger, push in the red button on the
handle. To stop automatic spraying, pull out the red button.
4. To increase motor speed (increase flow rate), turn the the motor speed dial
(next to the power switch) clockwise.
5. Spray facing away from the wind.
3.3 After spraying
1. Press O on the power switch and turn the motor speed dial all the way
counterclockwise.
2. Discharge residual pressure by pointing the wand in a safe direction and
squeezing the trigger.
3. After each use, clean the machine: Empty the tank and rinse with clean
water, then spray water. Wipe the exterior with a damp cloth.

4 Storage
 Turn off the power switch and turn motor speed dial to 0.
 Drain the sprayer tank and relieve any residual pressure.
 Store in a dry place and at least 20 inches above the ground.
 IMPORTANT: All Li-Ion batteries gradually drain when not in use. Li-
Ion batteries become unusable if they drain completely. If you will
not be using the sprayer for a long time, charge the battery to full and
recharge to full at least once every 3 months.
5 About the Li-Ion Battery
 Batteries drain over time: The battery is charged at the factory. How-
ever, it will self-discharge during transport and storage. When storing for
long periods, you must recharge the battery periodically - see storage
section.
 Batteries are consumable: Like all Lithium-ion batteries, the maximum
capacity will decrease over time. If battery life gets too low, it may be time
to replace it.
 Battery disposal: Don’t throw away Li-Ion batteries in the trash! Pro-
grams like Call2Recycle provide convenient drop-off locations that accept
your used Li-Ion batteries.
