SAFETY...YOU CAN LIVE WITH IT
EQUIPMENT SAFETY GUIDELINES
Every year many accidents occur which could have been avoided by a few seconds of
thought and a more careful approach to handling equipment. You, the operator, can avoid
many accidents by observing the following precautions in this section. To avoid personal
injury, study the following precautions and insist those working with you, or you yourself,
follow them.
In order to provide a better view, certain illustrations in this manual may show an assembly
with a safety shield removed. However, equipment should never be operated in this condition.
Keep all shields in place. If shield removal becomes necessary for repairs, replace shield
prior to use.
Replace any caution, warning, danger or instruction safety decal that is not readable or is
missing. Location of such decals is indicated in this booklet.
Do not attempt to operate this sprayer under the influence of alcohol or drugs.
Review safety instructions with all users.
Operator should be a responsible adult. DO NOT ALLOW PERSONS TO OPERATE OR
ASSEMBLE THIS UNIT UNTIL THEY HAVE DEVELOPED A THOROUGH UNDERSTANDING OF
SAFETY PRECAUTIONS AND HOW IT WORKS.
To prevent injury or death, use a tractor equipped with a roll over protective system (ROPS).
Do not paint over, remove, or deface any safety signs or warning decals on your sprayer.
Observe all safety signs and practice instructions on them.
Never exceed limits of a piece of machinery. If its ability to do a job, or to do so safely is in
question-DON’T TRY IT.
LIGHTING AND MARKING
It is the responsibility of customer to know lighting and marking requirements of local high-
way authorities and to install and maintain sprayer to provide compliance with regulations.
Add extra lights when transporting at night or during periods of limited visibility.

SAFETY SIGN CARE
•Keep safety signs clean and legible at all times.
•Replace safety signs that are missing or have become illegible.
•Replacement parts that displayed a safety sign should also display current sign.
•Safety signs are available from your distributor, dealer parts department, or factory.
How to install safety signs:
•Be sure that installation area is clean and dry.
•Decide on exact position before you remove backing paper.
•Remove smallest portion of split backing paper.
•Align decal over specified area and carefully press small portion with
exposed sticky backing in place.
•Slowly peel back remaining paper and carefully smooth decal into place.
•Air pockets can be pierced with a pin and smoothed out using piece of backing paper.
BEFORE OPERATION:
•Carefully study and understand this manual.
•Do not wear loose-fitting clothing which may catch in moving parts.
•Always wear protective clothing and substantial shoes.
•It is recommended that suitable protective hearing and eye protection be worn.
•The operator may come in contact with certain materials which may require specific safety
equipment relative to handling of such materials. (Examples: extremely dusty, molds,
fungus, bulk fertilizers, etc.)
•Give sprayer a visual inspection for any loose bolts, worn parts, or cracked welds, and make
necessary repairs. Follow maintenance safety instructions included in this manual.
•Be sure there are no tools lying on or in equipment.
•Do not use sprayer until you are sure that area is clear, especially around children and
animals.
•Don’t hurry learning process or take sprayer for granted. Ease into it and become familiar
with your new equipment.
•Practice operation of your equipment and its attachments. Completely familiarize yourself
and other operators with its operation before using.
•Use a utility vehicle equipped with Roll Over Protection System (ROPS) and fasten your seat
belt prior to starting engine.
•Manufacturer does not recommend usage of a utility vehicle with ROPS removed.

Page 7
•Move wheels on the utility vehicle to the widest recommended settings to increase stability.
•Do not allow anyone to stand between tongue or hitch and utility vehicle when
backing up to sprayer.
DURING OPERATION
•Beware of bystanders, PARTICULARLY CHILDREN! Always look around to make sure that it
is safe to start engine of utility vehicle or move sprayer. This is particularly important with
higher noise levels and quiet cabs, as you may not hear people shouting.
•NO PASSENGERS ALLOWED- Do not carry passengers anywhere on or in the utility vehicle
or sprayer.
•Keep hands and clothing clear of moving parts.
•Do not clean, lubricate, or adjust your sprayer while it is moving.
•When halting operation, even periodically, set utility vehicles brakes, disengage PTO, shut off
engine, and remove ignition key.
•Be especially observant of operating area and terrain- watch for holes, rocks, or other hidden
hazards. Always inspect area prior to operation.
- DO NOT operate near edge of drop-offs or banks.
- DO NOT operate on steep slopes as overturn may result.
- Operate up and down (not across) intermediate slopes. Avoid sudden starts and stops.
•Pick the most level possible route when transporting across fields. Avoid edges of ditches,
gullies, and steep hillsides.
•Be extra careful when working on inclines.
•Periodically clear sprayer of brush, twigs, or other materials to prevent buildup of dry
combustible materials.
•Maneuver utility vehicle at safe speeds.
•Avoid overhead wires. Contact with overhead lines could cause serious injury or death.
•Avoid loose gravel, rocks, and holes; they can be dangerous for sprayer operation or movement.
•Allow for unit length when making turns.
•Do not walk or work under raised components or attachments unless securely supported.
•Keep all bystanders, pets, and livestock clear of work area.
•Never stand alongside of unit with engine running or attempt to start engine and/or operate
machine while standing alongside of unit.
•Never leave running equipment attachments unattended.
•As a precaution, always recheck hardware on equipment following every 100 hours of operation.
Correct all problems. Follow maintenance safety procedures.

Page 8
FOLLOWING OPERATION
•Following operation, or when unhitching, stop utility vehicle, set brakes, disengage PTO and
all power drives, shut off engine and remove ignition key.
•Store unit in an area away from human activity.
•Do not park equipment where it will be exposed to livestock for long periods of time. Damage
and livestock injury could result.
•Do not permit children to play on or around stored unit.
•Make sure all parked machines are on a hard, level surface and engage all safety devices.
HIGHWAY AND TRANSPORT OPERATIONS
•Adopt safe driving practices:
- Keep brake pedals latched together at all times. NEVER USE INDEPENDENT BRAKING
WITH MACHINE IN TOW, LOSS OF CONTROL AND/OR UPSET OF UNIT CAN RESULT.
- Always drive at a safe speed relative to local conditions and ensure that your speed is low
enough for an emergency stop. Keep speed to a minimum.
- Reduce speed prior to turns to avoid risk of overturning.
- Always keep utility vehicle in gear to provide engine braking when going downhill. Do not
coast.
- Do not drink and drive!
•Comply with state and local laws governing highway safety and movement of farm machinery.
•Use approved accessory lighting flags and necessary warning devices to protect operators of
other vehicles on highway during transport. Various safety lights and devices are available
from your dealer.
•Use of flashing amber lights is acceptable in most localities. However, some localities prohibit
their use. Local laws should be checked for all highway lighting and marking requirements.
•When driving a utility vehicle and sprayer under 20 mph (40 kph) day or night, use flashing
amber warning lights and a slow moving vehicle (SMV) identification emblem.
•Plan your route to avoid heavy traffic.
•Be a safe and courteous driver. Always yield to oncoming traffic in all situations, including
narrow bridges, intersections, etc.
•Be observant of bridge loading ratings. Do not cross bridges rated lower than gross weight at
which you are operating.
•Watch for obstructions overhead and side to side while transporting.
•Always operate equipment in a position to provide maximum visibility at all times. Make
allowances for increased length and weight of sprayer when making turns, stopping, etc.
•SAFETY CHAINS: If equipment is going to be transported on a public highway, always
follow state and local regulations regarding safety chains and auxiliary lighting. Be sure to
check with local law enforcement agencies for your own particular regulations. If required
safety chains should be obtained and installed. Only safety chains (not elastic or nylon/
plastic tow straps) should be used to retain connection between towing and towed ma-
chines in event of separation of primary attaching system. Use a high strength, appropri-
ately sized hitch pin with a mechanical retainer and attach safety chains. Criss cross
chains under tongue and secure to draw bar cage, mounting loops, or bumper frame.

Your best assurance against accidents is a careful and responsible operator. If there is any
portion of this manual or function you do not understand, contact your local authorized dealer
or manufacturer.
PERFORMING MAINTENANCE
•Good maintenance is your responsibility. Poor maintenance is an invitation to trouble.
•Make sure there is plenty of ventilation. Never operate engine of utility vehicle in a closed
building. Exhaust fumes may cause asphyxiation.
•Before working on this machine, stop utility vehicle, set brakes, disengage PTO and all
power drives, shut off engine and remove ignition key.
•Be certain all moving parts and attachments have come to a complete stop before
attempting to perform maintenance.

cardboard or wood. Hydraulic fluid escaping under pressure can penetrate skin.
•Openings in skin and minor cuts are susceptible to infection from hydraulic fluid.
Without immediate medical treatment, serious infection and reactions can occur.
•When disconnecting hydraulic lines, shut off hydraulic supply and relieve all hydraulic
pressure.
•Replace all shields and guards after servicing and before moving.
•After servicing, be sure all tools, parts and service equipment are removed.
•Do not allow grease or oil to build up on any step or platform.
•When replacing bolts refer to owners manual.
•Refer to bolt torque chart on page 10 for head identification marking.
•Where replacement parts are necessary for periodic maintenance and servicing,
genuine factory replacement parts must be used to restore your equipment to original
specifications. Manufacturer will not claim responsibility for use of unapproved parts or
accessories and other damages as a result of their use.
•If equipment has been altered in any way from original design, manufacturer does
not accept any liability for injury or warranty.

SPRAYER CHECKLIST:
Downtime caused by field breakdowns is costly and time consuming. Many breakdowns can be
eliminated by periodic equipment maintenance. By spending time reviewing this checklist before
seasonal spraying application time and following proper after-season care, you can save time
and money later.

NOTE: DEMCOdoesnotandwillnotmakeanyrecommenda-
tionsconcerning applicationofvarious chemicals or
solutions.These recommendations relate to either
amount or procedure of materials applied. If you
have any questions regarding application of certain
chemicals or solutions, contact your chemical
supplier and follow chemical manufacturer
recommendations.
Check Before Going To The Field :
1. NOZZLES
Check tip for excessive wear by checking for grooves in
or near tip opening. Check nozzle spacing by starting
at center and working outwards. Check boom for proper
height.
2. HOSES
Check all hoses for worn or soft spots. Be sure all hose
clamps are tightened and hoses are not kinked or pinched.
Check for leakage in any lines.
3. TANK
Remove and clean agitator orifices. Check orifices for
excessive wear by checking for grooves in or near orifice
opening. Inspect fitting and grommets to insure they are
in good condition.
4. CONTROLS
Check for leakage, plugging, or wear on all valves, fit-
tings, etc. Clean off any build up of foreign material.
5. PUMP
Check to be sure pump turns freely.
6. FRAME
Be sure all bolts are tightened.
7. REPLACEMENT PARTS
Replace all worn or damaged parts.
After Season Care:
NOTE: It is important to wear proper safety equipment
when cleaning the sprayer. See your chemical or
fertilizer package for this information.
1. After spraying chemicals, run water mixed with cleaners
through tank, pump and all hose hookups. If wettable
powder dries out in the system, it is very difficult to
put back into suspension and can cause malfunction,
damage or injury.
2. When cleaned, tank should have all openings closed
or covered to keep dirt from entering.
3. Pump should be flushed with soluble oil and pump ports
plugged to keep out moisture and air.
4. Disassemble tips and rinse with water or cleaning
solution. (Appropriate for chemical sprayed).
5. Clean tip opening with a wooden toothpick. Never use
wire or hard object that could distort opening.
6. Dispose of all unused chemicals or solutions in a proper
and ecologically sound manner.
7. Water rinse and dry tips before storing.
•Keep hands, feet, and loose clothing away from rotating parts.
•Wear protective clothing recommended by your chemical and
fertilizer manufacturer when working with chemicals.
