The published torque values do not include the rotational drag of the elastic stop nuts (AN365). Standard
maintenance practice dictates that mechanics add this value to the specied torque. A random sample of new
and used AN365-4, and -5 nuts shows that the torque required to turn AN4 (1/4”) nuts varied between 15-19
in/lbs. The torque required onAN5 (5/16”) nuts varied between 18-22 in/lbs. This value must be added to the
torque value.

Modication for SwathPRO™
The SwathPRO™ system removes and replaces the factory spray booms.
The system added electronically controlled spray valves to control spray patterns.
The CapView display in the aircraft cockpit lets the pilot upload custom spray patterns and save preset
pattern proles for selection in-ight.
Spray on/o󰀨 is controlled by the use of the existing spray handle (with no changes) or rate controller, as
applicable.
The SwathPRO™ system is compatible with aftermarket rate controllers and spray nozzles.

Topics:
• Signal Words
• Emergency Safety
• Personal Protective Equipment
• Pressurized Fluid Lines
• Chemical Safety

Signal Words
DANGER: Indicates an imminent hazard which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations, typically for aircraft components that, for
functional purposes, cannot be guarded.
WARNING:Indicates a potential hazard which, if not avoided, could result in death or serious injury,
and includes hazards that are exposed when guards are removed. It may also be used to alert
against unsafe practices.
CAUTION: Indicates a potential hazard which, if not avoided, may result in minor or moderate injury.
It may also be used to alert against unsafe practices.
IMPORTANT: This is used to draw attention to specic information that is necessary for the operation, setup,
or service of the system.
Note: This is used for additional information that can help understand or operate the system.
Emergency Safety
Fire extinguishing systems must meet the applicable OSHA requirements, and all users of portable/ xed
re suppression equipment must know the types, limitations, and proper uses of this equipment; including
hazards involved with incipient stage reghting.
Keep emergency numbers for doctors, ambulance service, hospital, and re department near your telephone.
Know the location of re extinguishers and rst aid kits and how to use them.
Examine the re extinguisher and service the re extinguisher regularly.
Follow the recommendations on the instructions plate.
Very small res can be put out (extinguished) with a re extinguisher. Use an appropriate method to
extinguish a re (water for paper res, and chemical extinguishers for electrical or chemical res).

Section 3: Warranty
Topics:
• Limited Warranty

Limited Warranty
What does the Limited Warranty cover?
The ultimate purchaser/user (“you”), by acceptance of seller Capstan Ag Systems, Inc.’s, (“our,” “we,” or “us”)
product, assume all risk and liability of the consequences of any use or misuse by you, your employees, or
others.
All replacement components furnished under this warranty, but shipped before the failed component is
returned for evaluation, will be invoiced in the usual manner and warranty adjustments will be made after the
component claimed to be defective has been returned to and inspected and deemed defective by us at our
factory.
Upon determining that a component has failed under warranty, the repaired component or replacement
component, furnished under this warranty, will be shipped at our expense, to your location. We will credit you
an amount equal to the incoming freight you paid. We shall not be responsible for installation costs. (You shall
be responsible for all customs and brokerage fees for all international transactions.)
If the component does not prove to be defective, you shall be liable for all freight, inspection, and handling
costs. In no event will any claim for labor or incidental or consequential damages be allowed for removing or
replacing a defective product. Warranty will be denied on any component which has been subject to misuse,
abuse, accidents, or alterations, or to improper or negligent use, maintenance, storage, transportation, and
handling.
Our liability under this warranty, or for any loss or damage to the components whether the claim is based on
contract or negligence, shall not, in any case, exceed the purchase price of the components and upon the
expiration of the warranty period all such liability shall terminate. The foregoing shall constitute your exclusive
remedy and our exclusive liability.
The terms of this warranty do not in any way extend to any product which was not manufactured by us or
one of our a󰀩liates. While necessary maintenance or repairs on your CapstanAG product can be performed
by any company, we recommend that you use only authorized CapstanAG dealers. Improper or incorrectly
performed maintenance or repair voids this warranty.
The foregoing warranty is exclusive and is in lieu of all other warranties expressed or implied. We shall not be
liable for any incidental or consequential damages resulting from any breach of warranty.
Your exclusive remedy for breach of warranty shall be repair or replacement of defective component(s):
Provided, if the component(s) are incapable of being repaired or replaced, your exclusive remedy shall be
credit issued, but such credit shall not exceed the purchase price of the components.
On any claim of any kind, including negligence, our liability for any loss or damage arising out of, or from the
design, manufacture, sale, delivery, resale, installation, technical direction of installation, inspection, repair,
operation of use of any products shall in no case exceed the purchase price allocable to the components.
In no event, whether as a result of breach of contract or warranty or alleged negligence, shall we be liable for
incidental or consequential damages, including, but not limited to: personal injury, loss of prots or revenue,
loss of use of equipment or any associated equipment, cost of capital, cost of substitute equipment, facilities
or services, downtime costs, environmental damage, crop losses, or claims of customers of you for such
damages.

How does state law relate to this Limited Warranty?
Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not
apply to you.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you.
