Owner's Manual
Model: LSS-280 (5300467)
(200 Gallon Lawn Service Skid Sprayer)
Technical Specifications
• 5.5 Horsepower Recoil Start Engine
• 8 Roller Cast Iron Pump
• 10 Gallons Per Minute at 250 PSI
• Pressure Gauge-Adjustable Pressure Range
• Suction Line Filter
• Handgun-300' Handgun 1/2" Hose
• Dual Jet Agitation
Operation
Add gas and oil to the engine as specified in the engine manual. Check
the side port of the engine gear case for lubricant. Add more lubricant if
necessary. See the engine manual for type of lubricant needed.
It is important to test the sprayer with plain water before attempting actual
spraying. This will enable you to check the completed sprayer for leaks in
the plumbing system.
1. Open tank lid and be sure the tank is clean and free of foreign material.
Fill the tank about one half full with plain water.
2. Open the valve in the strainer assembly and allow water to flow to the
pump. (The valve is located at this point to enable the strainer to be taken
apart for cleaning.)
CAUTION: Always be sure that water has reached the roller pump
before starting your sprayer. If the pump is run dry, serious damage
to the pump will result.
General Information
Thank you for purchasing this product. The purpose of this
manual is to assist you in operating and maintaining your skid
sprayer. Please read it carefully, as it furnishes information
which will help you achieve years of trouble-free operation.
Warranty/Parts/Service
Products are warranted for one year from date of purchase
against manufacturer or workmanship defects.
Commercial users have a 90 day warranty.
Your authorized dealer is the best source of replacement parts
and service. To obtain prompt, efficient service, always
remember to give the following information...
3. It is always best to start the sprayer at little or no pressure. This
sprayer is equipped with a spring loaded relief valve. Turn the valve
handle out to decrease pressure and in for increased pressure. The
location of the relief valve and other important components may be found
by referring to the exploded view drawings.
4. The pumping system includes an agitator which will help keep the
solution in suspension. Pressure to the agitator should never exceed 100
PSI. When spraying at pressures over 100 PSI, use the brass valve (in
the hose reel/agitator plumbing assembly) to throttle the pressure to the
agitator by closing the valve. As solution is forced through the agitator,
the venturi action triples the flow through the agitator. The valve in the line
may shut off the agitation completely when not needed, or it can throttle
the amount of solution going to the agitator if too much agitation occurs.
5. You may now start the sprayer engine following the engine
manufacturers instructions. Let the sprayer run at low pressure until water
has reached the handgun, and all air has been purged from the handgun
line.
6. The pressure should now be increased to 30-40 PSI. Operate the
sprayer at this increased pressure for 3-5 minutes, thoroughly testing the
unit before adding chemicals.
7. The sprayer should now be ready for adding chemicals.
- Correct Part Description and/or part number.
- Model number/Serial number of your sprayer.
Part descriptions and part numbers can be obtained from the
illustrated parts list section(s) of this manual.
Whenever you need parts or repair service, contact your
distributor/dealer first. For warranty work, always take your
original sales slip, or other evidence of purchase date, to your
distributor/dealer.

After Spraying
After use, fill the sprayer tank part way with water.
Start the sprayer, and allow the clear water to be
pumped through the plumbing system and out
through the spray nozzles.
Refill the tank about half full with plain water and
use FIMCO Tank Neutralizer and Cleaner, and
repeat cleaning instructions above.
Flush the entire sprayer with the
neutralizing/cleaning agent, then flush out one more
time with plain water. Follow the chemical
manufacturer's disposal instructions of all wash or
rinsing water.
For the boom, (if applicable) remove the tips and
screens from the nozzle assemblies. Wash these
items out thoroughly. Blow the orifice clean and dry.
If the orifice remains clogged, clean it with a fine
bristle (NOT WIRE) brush, or with a toothpick. Do
not damage the orifice. Water rinse and dry the tips
before storing.
WARNING: Some chemicals will damage the
pump valves if allowed to soak untreated for a
length of time! ALWAYS flush the pump as
instructed after each use.
Winter Storage
Drain all water out of your sprayer, paying special
attention to the pump, handgun, and valve(s).
These items are especially prone to damage from
chemicals and freezing weather.
The sprayer should be winterized before storage
by pumping a solution of RV antifreeze through the
entire plumbing system. This antifreeze solution
should remain in the plumbing system during the
winter months. When spring time comes and you
are preparing your sprayer for the spray season,
rinse the entire plumbing system out, clearing the
lines of the antifreeze solution. Proper care and
maintenance will prolong the life of your sprayer.
