PETROLEUM BASED OR OTHER CORROSIVE SOLUTIONS OR HEAT, PRESSURE,

OR GAS PRODUCING CHEMICALS. ALWAYS READ AND FOLLOW CHEMICAL

MANUFACTURER’S INSTRUCTIONS BEFORE USE WITH THIS SPRAYER AS

SOME CHEMICALS MAY BE HAZARDOUS WHEN USED WITH THIS SPRAYER.

ENSURE THE WIRING HARNESS DOES NOT BECOME PINCHED OR DAMAGED

IN ANY WAY. THIS MAY DAMAGE THE PUMP OR CAUSE THE WIRING

HARNESS TO OVERHEAT, RESULTING IN MELT DOWN OR FIRE.

ASSEMBLE PUMP TO TANK

Using H-1 screws, fasten pump (C-2) to face plate with loop clamp (H-6) inserted between

pump and front left screw. NOTE: Do not over-tighten screws.

INSTALL EXTERNAL BYPASS AND FLOW DIRECTOR VALVE

Install external bypass (C-3) and ﬂow director valve (C-4) into pump quick release ports;

engage quick release locks. Note: to ensure a good seal, a tight ﬁt is used; signiﬁcant hand

force may be necessary to install bypass ﬁttings.

Retaining Nut

Make sure the o-ring is installed on the end of the wand. Insert the wand into shut-off valve.

Turn and tighten the retaining nut clock-wise onto the shut-off valve.

ATTACH CHEMICAL CONCENTRATE TANK

Before chemical tank installation, attach supplied rachet straps to strap slots on tank.

Securely fasten assembly to ATV. NOTE: not all models included ratchet straps.

Attach the mix valve’s suction tubing (1) to the chemical concentrate tank’s quick release

port (2). Secure chemical concentrate tank with nylon webbing (3).

SPRAYER COMPONENTS

MIX SETTING VALVE

The mix setting valve allows the user to

set the desired chemical mix ratio. It is

calibrated to a speciﬁc gravity of water.

See setting chart for each settings mix

value in oz./gal. Due to chemical viscosity,

actual mix ratios may vary. Refer to

chemical’s recommended mix ratios

when choosing what setting to use.

Note:

• Use water based chemicals only.

• When not spraying set mix ratio to zero.

WAND / BOOM SELECTOR VALVE

The wand/boom selector valve allows the user to select the ﬂow to either be diverted to

the wand assembly or the boom.

BYPASS / PRESSURE VALVE

The bypass/pressure valve allows the user to adjust the wand’s pressure. During low ﬂow

applications it allows ﬂow to be diverted to eliminate pump cycling.

How to use: Start with the valve set to “Bypass off”. When the pump begins to cycle;

between on and off, turn the valve slowly counter clockwise until the cycling stops. The

valve setting should fall in the “optimal” ﬂow region.

Note:

• If the bypass is used beyond the “optimal ﬂow” region the pump may not shut off as

the bypass doesn’t allow it to build enough pressure to turn the pump off.

• If too much air is introduced into the system from changing chemicals or running the

water or chemical tanks dry it may be necessary to switch the bypass valve to “Bypass

off/Prime” in order to prime the unit.

CHEMICAL CONCENTRATE TANK

The chemical concentrate tank is where the chemical concentrate is held. To install the

tank, insert the tank onto the faceplate’s alignment feet and secure with the nylon webbing

and snap latch.

CHEMICAL TANK QUICK RELEASE COUPLING

The chemical tank quick release coupling allows the user to quickly and cleanly change

out chemical tanks. When disengaged the tank’s quick release automatically closes to

stop spillage. To use, align the male locking pins with the female nut’s slots. Press female

nut over the male nut and turn clockwise to lock in place. To disengage the quick release

coupling, slightly push the female nut in, turn counterclockwise and remove.

OPERATING INSTRUCTIONS

1. Fill both water and chemical tanks.

2. Set Mix Ratio Valve to “0” (1) by turning the adjustment wheel.

3. Set Wand/Boom selector valve to “Wand” (2).

4. Set Bypass to “Bypass Off/Prime” (3) by turning the selector knob.

5. Turn system on by pressing wiring harness in-line switch to “on” (not shown).

6. Prime: using the wand spray until all air has been purged from the system. If the

bypass was set to “off” the pump will begin to cycle on and off.

7. Adjust bypass until the pump stops cycling. Do not bypass more than needed as this

will cause the pump to continuously run.

8. Set the desired mix ratio setting and begin spraying.

9. Cleaning between chemical types: While spraying on mix setting 7 disconnect the

concentrate tank’s quick release. This allows chemical in the line to quickly be ﬂushed.

If necessary, ﬂush with water by submerging the chemical line into the water source.

Once adequately ﬂushed the new concentrate tank may be installed. With the mix

valve set to 7 and the bypass set to “Bypass off/Prime” prime the system. Once

primed, re-adjust the bypass valve and you’re ready to spray.

CAUTION

ALWAYS FOLLOW CHEMICAL MANUFACTURER’S INSTRUCTIONS FOR

PROPER USE, STORAGE AND DISPOSAL.

ALWAYS FOLLOW STATE/LOCAL CODES FOR PROPER HANDLING,

STORAGE AND DISPOSAL OF CHEMICAL.

Chemical mix ratios can easily be adjusted in

between or lower than the listed 0-7 settings by

pre-diluting your concentrate.

For example, if you wish to spray at .5 oz/gal, simply

mix your chemical 50:50 with clean water before

placing it in the concentrate tank.

Divide the desired rate by the closest higher rate

(oz. /gal) value from above guide to determine the %

of chemical in concentrate tank.

Adjust external bypass to optimize spray pattern

Pump makes noise, but

no output

Prime with garden hose by removing intake hose and ﬂood with

water while pump is running until water starts ﬂowing (this may

take up to 15 minutes to create suction).
