What should you do if you need repairs or parts under Warranty?
How to get parts and or repairs done under warranty:
Notify YOUR DEALER immediately when you discover a faulty material, workmanship, or
faulty component. Do not wait weeks or months to get it reported. Be sure to tell the dealer
that this is a failure that occurred under warranty.
NOTE: Warranty work must be done by an Authorized Dealer in order to be covered by
the Warranty Program, unless otherwise approved by the Warranty Administrator.
Instructions to Dealer on processing warranty work:
Initiating a claim
1. Be sure to have the model, serial number and number of hours on unit.
2. A description of the problem as understood at the time.
3. Call the Warranty Administrator to secure warranty claim authorization number.
4. ConÞrm with Warranty Administrator that the unit is eligible for warranty coverage.
5. Any parts needed for the repair work should be placed with the Warranty Administrator
instead of the parts department. These will be shipped to you at no charge pending the
outcome of the investigation.
6. Labor hours must coincide with the published “Labor Schedule” or estimate approved
by the Finn Warranty Administrator.
7. Once work is done, a Warranty Claim Form must be Þlled out and emailed along with
any related receipts or invoices to the Warranty Administrator. We ask that this is done
ASAP after work is completed.
Faulty or failed parts:
IF the Warranty Administrator wants you to return failed parts, you will receive a return
shipping label in the package with new parts. On that Label will be marked a return
authorization number. (Which is the same number as you claim number.)
Please also mark the outside of the package that you are shipping back (using a marker)
with the claim/return number. THESE PARTS MUST BE RETURNED WITHIN 10 DAYS!
Failure to do so can void warranty coverage.
NOTE: Further information and related forms can be found on the web site in the Dealer
Portal warranty section.
ACTIVATE YOUR EQUIPMENT WARRANTY
It is the responsibility of the Dealer to register your Equipment shortly after the equipment
start-up and operation overview. You must register your machine at time of purchase at
www.apexseeder.com/warranty/ for warranty coverage.
Be sure to conÞrm with your sales representative that this has been done completely.
This registration process activates the Limited Warranty.

PRE-OPERATION INSPECTIONS
The Pre-Operation Inspection that an operator does before starting a piece of equipment is the
single most important responsibility of the day. The operator is the key component in the walk-around
and it is their responsibility to solicit help as required if areas of distress or concern are noted.
Cell phones and digital pictures are extremely helpful when communicating potential problems or
concerns.
Many operators overlook vital aspects of the walk-around such as fluid type and quantity. To
maximize the effectiveness of a fluid it must be the proper viscosity and quality at starting
temperatures. Next in degree of importance is the fluid quantity. Too much fluid can be as harmful as
too little fluid. Be sure all fluids are in the proper level range and refer to the Fluid Specifications and
Tank Capacities Chart of this manual whenever replacing or adding fluids.
The walk-around should be performed before each shift and before moving the machine or
even starting the engine.
The following describe in detail the recommended items to be checked, whether it is a daily
check (every 8 hours) or a weekly check (every 40 hours).
Once the Pre-Operation Walk-Around is complete a final inspection should be done by operating the
applicator for a short period of time. Stop the unit and check the gauges and display screen.
