Every year many accidents occur which could be avoided by a few seconds of thought and
more careful approach to handling equipment. You, the operator, can avoid accidents by
observing precautions in this section. To avoid personal injury, study 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, sprayer 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
ASSEMBLETHIS SPRAYER UNTIL THEY HAVE DEVELOPED ATHOROUGH 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 sprayer. 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 operator to know lighting and marking requirements of local highway
authorities and to install and maintain equipment to provide compliance with regulations.
Add extra lights when transporting at night or during periods of limited visibility.
Lighting kits are available from your dealer or manufacturer.

HIGHWAY AND TRANSPORT OPERATIONS
• Adoptsafedrivingpractices:
- Keep brake pedals latched together at all times. NEVER USE INDEPENDENT BRAKING
WITH SPRAYER IN TOW. LOSS OF CONTROL OR UPSET MAY 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 tractor or towing unit in gear to provide engine braking when going
downhill. Do not coast.
- Do not drink and drive!

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 machines in event
of separation of primary attaching system. Use a high strength, appropriately 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.

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: DEMCO does not and will not make any
recommendationsconcerning applicationofvarious
chemicals or solutions. These recommendations
relate to either amount or procedure of materials
applied. If you have any questions regarding
applicationofcertainchemicalsorsolutions,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, fittings,
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 SIDEQUEST ® . 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.
6. Water rinse and dry tips before storing.
