Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
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 potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.
Prepare for Emergencies
Be prepared if a fire starts
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
Thoroughly read and understand “Safety Decals”
starting on page 6 of the 411-332M Operator Manual.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

3P3025AH Table of Contents Important Safety Information 2
Wear Protective Equipment
Wear protective clothing and equipment.
Wear clothing and equipment appropriate for the job.
Avoid loose-fitting clothing.
Because prolonged exposure to loud noise can cause
hearing impairment or hearing loss, wear suitable
hearing protection such as earmuffs or earplugs.
Because operating equipment safely requires your full
attention, avoid wearing entertainment headphones while
assembly or operating machinery.
Use A Safety Chain
Use a safety chain to help control drawn machinery
should it separate from tractor draw-bar.
Use a chain with a strength rating equal to or greater than
the gross weight of towed machinery.
Attach chain to tractor draw-bar support or other
specified anchor location. Allow only enough slack in
chain to permit turning.
Replace chain if any links or end fittings are broken,
stretched or damaged.
Do not use safety chain for towing.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
If an accident occurs, seek immediate medical assistance
from a physician familiar with this type of injury.
Minimize Radiation Exposure
The radar is an intentional radiator of RF energy.
Although its radiated energy level is far below the limits
set by EN 61010-1:1993 A2:1995-Chapter 12.4, it is
advisable not to look directly into the face of the unit.
The radar must radiate toward the ground and at least 20
cm (8 inches) away from a human during use to comply
with the RF human exposure limits as called out in
FCC 47 CFR Sec.2.1091. DO NOT RE-MOUNT OR
USE THE RADAR IN A MANNER INCONSISTENT
WITH ITS DEFINED USE.

Unloading
Have the driver spot the truck as marked during
See “Plan the Unload” on page 8.
Unload Smaller Items First
If the planter does not have rear lift assist, make sure the front
gauge wheels are installed on the planter.
Unloading the planter is a potentially dangerous
operation.
Reduce risk and complication by first unloading any
miscellaneous crates.
Place these components well out of the maneuvering
area needed for unloading the planter.
Unload The Planter
1. Double-check that all chains and tie-down straps
have been released and stowed.
2. If the planter does not have rear lift assist, make sure
the front gauge wheels are installed on the planter.
3. Make sure that all team members are fully briefed
and ready.
4. Set parking brake on trailer tractor.
5. Put the lifting equipment in position. See “Raising
the Drill” on page 11.
Lifter-Trailer Contact Risk:
Do not move the fork lifts or crane so far in that trailer wheels
will not be able to clear them when pulling trailer out from
under drill.
Load “Wedging” Risk:
If using multiple fork lifts, do not drive the fork lifts fully
forward into the drill, unless the fork lifts are known to have
precisely vertical motion. If the load moves forward while
lowering, the drill will tend to push the fork lifts backward.
6. Slowly lift the drill off the trailer bed.
7. Stop lifting about 12in above the bed.
8. Have the truck driver slowly pull the trailer straight
out from under the drill.
9. Making sure to keep level from front to back and side
to side, slowly lower the drill to the ground.
10. Lower forks and withdraw fork lifts.

Seeding Switch, Planters With Hydraulic Drive
Planters Without Rear Lift Assist
Refer to Figure 13
The seeding switch signals the seed monitor when
the drill is lowered for planting. If the drill has hydraulic
drive for the row units, the seeding switch also activates
the hydraulic drive.
Great Plains recommends adjusting the seeding switch
for your exact field conditions and planting depth.
Check the seeding switch seasonally thereafter, or
when planting conditions change. Also perform this
adjustment if the seeding switch is replaced or
dislodged.
The switch bracket uses a magnet for mounting.
The seeding switch must be mounted where the toggle
arm is actuated by the lift arms on the tractor.
When installing, adjusting, or replacing the seeding
switch, make sure the cable exit is at the bottom. If
the cable exit is at the top, moisture will accumulate in
the seeding switch, causing failure.
1. Put the planter in the field position.
2. Lower the drill to the height at which seed delivery
is to begin.
3. Apply the tractor parking brake, stop the engine,
and take the key with you.
4. Find a location where the switch bracket can be
mounted with the magnet. The toggle arm must be
actuated by the lift arms on the tractor while
planting. the toggle switch must be free of the lift
arms when the planter is raised by the 3-point
arms.
5. Slide the switch bracket to move seeding switch up
or down. Adjust switch bracket so toggle arm just
makes contact with tractor 3-point lift arms.
6. Move the switch bracket down 1/4inch (6.4 mm).
