HOW TO PREPARE YOUR BACK PACK SPRAYER FOR USE
1. To adjust pump handle to pumping position, remove retaining clip on bottom
of tank base (fig. 4, item 41) and pull pump handle out until disengaged.
Realign and insert clip.
2. To install pump handle on opposite side of sprayer, remove retaining clip
on bottom of tank base and slide the pump handle out of center crank.
Unsnap center crank (fig. 4, item 40) from bushing (fig. 4, item 42); move
bushing to other side; turn center crank and snap back into bushing; reinsert
pump handle from side and snap on clip.
3. Attach telescoping extension wand to discharge valve by hand only. It is
not necessary to over-tighten.
4. Mix spray solution in separate receptacle, following directions on spray
solution container.
5. Remove cap at top of tank and pour solution into tank through the filtering
screen.
6. Replace cap and tighten securely.
7. Pressurize tank by pumping pump handle.
8. Adjust pressure by turning the pressure control valve on the pump. Turn
pressure control valve to right to increase pressure; to left to decrease
pressure.
9. Check packing seal nut (fig. 3, item 26) and tighten if loose to avoid leakage
at pump shaft.
10. Lower strap attachment clip (fig. 2, item 13) can be snapped out of base
allowing either strap to be adjusted for easier mounting on the back. After

HOW TO USE YOUR BACK PACK SPRAYER
1. Adjust nozzle tip (fig. 6, item 67). Tighten tip for fine spray or loosen for
coarser spray or solid stream. WARNING: Loosening tip too far will result
in tip coming off, allowing spray substance to spray back at you or in
uncontrolled directions.
2. Optional fan tip with fixed pattern replaces adjustable tip and body (fig. 6,
item 68, 69, 70). Store optional fan tip assembly or adjustable nozzle tip
assembly when not in use by snapping into storage slot in service panel
(fig. 1, item 6).
3. Pump to maintain desired pressure level and spray pattern.
4. Sprayer should only be carried by carry handle or straps on back of tank.
5. Use caution when shortening telescoping wand as a small amount of
chemical will be discharged out of spray tip.
CLEANING AND MAINTENANCE INSTRUCTIONS
1. Release air pressure by turning pressure control valve (fig. 3, item 29) in
counterclockwise direction.
2. Loosen cap (fig. 1, item 8) and pour out any remaining spray solution.
Rinse all parts thoroughly with clean water.
3. Leave a small amount of clean water in tank, pressurize and flush hose
and discharge valve.
TO DISASSEMBLE PUMP FOR MAINTENANCE
1. Remove the service panel (fig. 1, item 6) by pressing on the three tabs
located on the center and sides of the panel. Pull the panel out through
the bottom of the base.
2. Pull hose through bottom of tank base.
3. Remove retaining clip (fig.4, item 41) from bottom of tank base. Remove
pump handle.
4 Loosen pump cap (fig. 1, item 5) by turning counterclockwise until it is free
of the threads and remove through bottom of tank base.
5. Slide pump housing (fig. 3) out of tank cavity.
6. Inspect O-ring (fig. 3, item 17) for damage or wear. Replace if necessary.
7. Inspect filter screen (fig. 3, item 18) for dirt or debris. Rinse with clear water
or replace if necessary.
8. Remove pressure control valve (fig. 3, item 29) adjusting knob by turning
counterclockwise. Inspect for damage or wear. Replace if necessary.
9. Unscrew pressure chamber (fig. 3, item 21) from pump cylinder (fig. 3, item
16). Inspect O-ring (fig. 3, item 20) for wear. Replace if necessary. Remove
check valve (fig. 3, item 19) on top of pump cylinder. Inspect all sealing
surfaces on both the valve and the cylinder areas for debris and scratches.
It is important for these areas to remain clean or the unit will not
pressurize. Replace check valve if necessary.
10. Unscrew the pump nut (fig. 3, item 25) to reveal the pump cup retainer
assembly (fig. 3, item 22 & 23). Carefully inspect the external surfaces of
the cup for scratches or cracking. Also inspect the mating pump cylinder
walls for scratches. Excessive wear will cause the pump to lose efficiency.
Replace as necessary.
11. Remove the packing seal nut (fig. 3, item 26) from the pump nut (fig. 3,
item 25). Inspect all sealing surfaces on the rod and nut for scratches.
Replace as necessary.

necessary.
13. Re-install pump assembly to tank, making sure that the discharge hose
is aligned to the groove in the base prior to tightening the pump cap. It
is important for the hose to be aligned to the base so that the hose does
not interfere with the pumping operation during use.
