WARNING!
IMPROPER USE OR FAILURE TO FOLLOW INSTRUCTIONS CAN RESULT IN
PRODUCT FAILURE OR INJURIES. FOR SAFE USE OF THIS PRODUCT YOU MUST
READ AND FOLLOW ALL INSTRUCTIONS BEFORE USING.
WARNING: Handling the brass parts of this product will expose you to lead, a chemical
known to the State of California to cause birth defects and other reproductive harm.
Wash hands after handling.
CAUTION
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.
1E
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
diluted household bleach (max. 1 part household bleach to 9 parts water solution).

INSTALLING THE PUMP HANDLE
The pump handle can be mounted on either side of the pump
shaft (A).
To install the pump handle place the handle (C) over
the shaft (A) aligning the pump handle hole and shaft hole. Push
the straight side of the cotter pin (B) through the aligned hole as
shown in figure 1 thru 3. There are holes in the pump handle to
allow for either left(fig.4) or right (fig.5) hand mounting.

4 STAGE FILTERING SYSTEM
This backpack sprayer is equipped with a 4 stage filtering system (see figure 1).
Stage 1 is a filter basket incorporated into the tank opening where fluid is
added. Stage 2 and 3 filters are located at the inlet of the pressure cylinder.
Stage 2 is a removable In-Tank filter. Stage 3 is a removable filter cartridge
integrated into the pressure cylinder. Stage 4 is a removable filter incorporated
into the shut-off assembly. Periodic cleaning of these filters is recommended to
insure consistent fluid flow through the sprayer. This will also reduce sprayer
component wear.
Stage 3 filter cartridge cleaning requires removal of the entire pressure cylinder
assembly (see section “disassembling and repairing the pressure cylinder”).
Once the pressure cylinder is removed the stage 3 filter can be removed for
cleaning (see figure 3). Periodic cleaning of the stage 2 filter is highly
recommended and will reduce the need to perform this disassembly. It is best
to have no or minimal fluid in the tank before removing and reinstalling the
stage 2 In-Tank filter. The In-Tank filter needs to be oriented in a specific way
when inserted into the pressure cylinder base (see figure 2).
The stage 4 filter is a removable filter incorporated into the inlet side of the
shut-off valve (see section “disassembling and repairing the shut-off valve”) .
Make sure pressure is released before detaching the hose from the shut-off. It
is best to have no or minimal fluid in the pressure cylinder before removing
and reinstalling the stage 4 shut-off filter as fluid can leak from the hose.

FILLING THE SPRAYER
Make sure the filter basket is in place to keep debris from entering the tank.
Determine the amount of mixture needed for your application. Add the proper amount of water to the
tank. Add the proper amount of chemical to the tank (check the chemical label for proper ratio of
chemical). Stir mixture in tank with a clean utensil (like a paint stirrer). The tank will hold the 4-gallon
(15.1L) capacity plus the chemical.
It is not necessary to completely fill the sprayer tank with each use. You can fill the tank with only the
amount needed for each application.
Always follow the manufacturer’s instructions included on their product label.

HELPFUL SPRAYING INFORMATION
Use RAPID pump strokes to prime the pump.
You will know the pressure chamber is filling with liquid
when you feel firm resistance from the pump. The air in the pressure chamber is compressed from
repeated strokes. By pressing the hand lever on the shut-off, the valve opens. For safety lock-off feature
(no-spraying), pull up on handle and move red locking mechanism into lock-off position as shown in fig.
1. To disengage, push down on handle and return red locking mechanism to neutral position as in fig. 3.
For lock-on feature (continuous spraying), push down on handle and move red locking mechanism into
lock-on position as shown in fig. 2. To disengage, push down on handle and return red locking
mechanism to neutral position as shown in fig. 3.

Handle

Figure 1 Figure 2 Figure 3
For easy pump action use the END of the pump handle. The amount of liquid delivered during spraying
depends on the rate of pump stroke. The fan nozzle tip is rated at .4 gpm at 40psi. This is the nominal
operating pressure of the sprayer.
Note:
If you experience a rapid drop in pressure, drain the sprayer completely and pump the handle
with an empty tank. The pressure chamber will fill with the required volume of air to repressurize.
Chapin advises performing this procedure from time to time as routine maintenance.
POWDER-BASED CHEMICALS
Powder
-based chemicals (powder mixed with liquids to make the spraying agent) are usually abrasive
and can cause wear. When you use a powder-based chemical in your sprayer, make sure it is thoroughly
dissolved in the liquid solution. Thoroughly clean and flush the sprayer with water to extend the life of
the sprayers parts.
CLEANING
1) Always empty the sprayer and clean the tank thoroughly after each use.
2) Pump the sprayer handle until all of the contents and air exit through the nozzle (minimum of 30
strokes).
3) Fill tank half way with water and pump the water out as explained in step 2 (repeat several times as
necessary).
Other Cleaning Hints:
• Improper spray distribution usually means the nozzle is clogged, remove the nozzle and clean it.
• Soap can be added to the water to clean the tank.
• Do not use strong cleaning agents or abrasives.
• If you use a chemical agent to clean the tank follow the manufacturer’s recommendations for the
disposal of the waste water.
• Follow the chemical manufacturers instructions for clean up.
5E
STORING / MAINTAINING YOUR SPRAYER
• The sprayer should be stored out of direct sunlight in a cool dry space.
• Before freezing weather make sure to drain all liquid in the tank
, pump, pressure cylinder, hose,
shut-off valve, wand and nozzle, to avoid liquid expansion and cracking in the sprayer components
(See “Cleaning” section). Lock the shut-off valve in the “open” position.
• When service is required call your nearest dealer and always insist on original manufactured
replacement parts.
• Inspect the hose, wand, pump, tank and shut-off valve for wear, damage or leaks on a regular basis
and repair defects promptly.
