LUMBAR SUPPORT INSTALLATION
1. Fit slots in lumbar support over mount support tabs of sprayer
base. (This must be done prior to installing shoulder strap ring).
2. Use a flat screwdriver to separate shoulder strap ring at end of
strap – insert ring end through hole in mount support tabs on base
of sprayer. Turn ring until completely through hole. Make sure
straps are not twisted. When attaching the waist belt simply snap
hooks into rings of shoulder strap.

extension must be attached to shutoff assembly. Make certain that
valve seat is in place before attaching. Tighten firmly.

OPERATION
Always conduct a test using clean water before mixing chemicals.
1. Prior to each use of sprayer, check all connections (i.e.: hose,
shutoff handle, extension, etc.) to make certain they are firmly
secured.
2. Lightly lubricate pump rod near the rod seal grommet to seal and
increase the life of rod and grommet.
3. Whenmixingchemicals,followpackagelabelinstructions.Mix
chemicals in a separate container.
4. Make sure shutoff control is in OFF position.
5. Remove filler cap – leave filter screen in place to prevent sediment
and particles from entering the tank. Fill sprayer to desired level.
6. Replace filler cap – make sure cap is tight.
7. Clean spilled material fromsprayerbeforeuse.
8. Mount sprayer on back and adjust shoulder straps and waist belt
tofitcomfortably.
High Pressure Chamber Operation
9. Work pump handle up and down approximately 6-8 times to
pressurize sprayer reservoir. The pump handle will become hard to
move when you reach maximum pressure. To maintain pressure,
pump handle occasionally (approximately every other step while
walking and spraying). If using pressure regulator, adjust to
desired pressure at this time.
10. You are ready to start spraying. Press shutoff lever up and down
for intermittent spraying. Hold lever up and engage lock to provide
continuous spraying. Adjust nozzle for desired spray pattern.
Low Pressure Chamber Operation
11. Pump handle 1~3 times to reach initial operating pressure, then
again as needed. The low pressure bladder maintains constant
pressure and eliminates the need for a pressure regulator. DO NOT
OVERPRESSURIZETHEINTERNALBLADDER.
