Preparation and Setup
This section helps you prepare your tractor and 8315,
8318, 8321 & 8324DVNfor use, and covers seasonal
tasks, and tasks when the tractor/Discovator configura-
tion changes.
Before using the 8315, 8318, 8321 & 8324DVN in the
field, you must hitch the Discovator to a suitable tractor,
inspect systems and level the Discovator. Before using
the Discovator for the first time, and periodically thereaf-
ter, certain adjustments and calibrations are required.
Initial Setup
See “First Time Field Adjustments” on page 37 and
“Hitching a Trailing Implement (Optional)” on page 36
for pre-delivery items (normally completed by dealer),
and first-time/infrequent setup tasks, including:
❑ Remove protective film from large highway reflec-
tors.
Seasonal Setup
On initial delivery, use with a new tractor, and seasonally,
check and as necessary, complete these items before
continuing to the routine setup items:
❑ Bleed hydraulic system (page 30).
❑ Wing levelling and alignment (page 38).
❑ De-grease exposed cylinder rods if so protected at
last storage.
Pre-Tilling Setup
Complete this checklist before routine setup:
❑ Read and understand “Important Safety Informa-
tion” on page 5.
❑ Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
❑ Make sure your tractor horsepower matches the
implement you are pulling. This is important so the
implement can do the best possible job.
❑ Clean all hydraulic couplings and connect to tractor
as shown on page “Hydraulic Hose Hookup” on
page 20.
❑ If machine is folded, be sure the wing lock valve is
locked. Remove wing locking pins. Open the lock
valve on front of brace bar and slowly unfold the unit.
Make sure no one is under the wings during the
unfolding process.
❑ Check again for hydraulic leaks and watch that
hoses do not get pinched in hinges, wing stops, etc.
❑ After the machine is completely unfolded, remove
both transport locks from lift cylinders, raise and
lower the Discovator several times to purge air from
the hydraulic system. Again check for hydraulic leaks
and tighten or replace if necessary.
❑ Check safety chain hookup. Make sure all warning
lights are hooked up and functioning correctly.
❑ Put transport locks back in place on lift cylinders.
❑ Check that all grease fittings are in place and lubri-
cated. See “Lubrication and Scheduled Mainte-
nance” on page 45. The hubs will come pre-greased
and will not need greased at this time.
❑ Check that all safety decals and reflectors are cor-
rectly located and legible. Replace if damaged. See
“Safety Decals and Lights” on page 10.
❑ Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation Chart”
on page 64.
❑ Re-fold the machine slowly. Close the lock valve on
the front of the brace bar. Always use the transport
locks and close lock valve when moving from field to
field. You are now ready to go to the field.
