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, and the color Safety Red, indicate 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 machine components
that, for functional purposes, cannot be guarded.
WARNING, and the color Safety Orange, indicate 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, and the color Safety Yellow, indicate a
potential hazard which, if not avoided, may result in
minor or moderate injury. It may also be used to alert
against unsafe practices.

Operating Instructions
This section covers general operating procedures. It
assumes that setup items have been completed.
Experience, machine familiarity and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
General Description
Field operations are controlled by a tractor cab hydraulic
lever. When openers are lowered, a mechanical clutch
engages, and the left end wheel drives the seed meter
shaft.
Seed and fertilizer meters operate at a rate proportional
to ground speed, as set by sprockets and/or rate handle,
based on the rate charts, and calibration.
Seeding depth and furrow coverage are controlled by drill
down pressure and row unit setup.
Pre-Start Checklist
❑ Lubricate the drill as indicated under Lubrication,
“Maintenance and Lubrication” on page 36.
❑ Check the tires for proper inflation according to
“Tire Inflation Chart” on page 52.
❑ Check for worn or damaged parts and leaks.
Repair or replace before going to the field.
❑ Check all nuts, bolts and screws. Tighten bolts as
specified on “Torque Values Chart” on page 54.
High Pressure Fluid Hazard:
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 attention from a physician familiar with
this type of injury.

Raising Openers for Transport
The opener sub-frame is on a dedicated hydraulic circuit.
The openers raise and lower as a group, controlled from
a tractor cab lever.
The following instructions presume that the openers are
lowered, and need to be raised for transport.
Loss of Control Hazard:
Failure of the hydraulic cylinder during transport causes the
openers to drop suddenly, which could lead to serious road
accidents, injury or death. To prevent an accident, always
install the pivot-stop pin in the transport-lock position before
transporting the drill.
Opener Pivot Stop
1. Hitch the drill to a suitable tractor. See “Hitching”on
page 13.
Negative Tongue Weight Hazard:
Raising openers on an unhitched drill causes the drill tongue
to rise suddenly, which could cause serious injury or death. Be
certain that drill is hitched securely to your tractor drawbar
and the safety chain is securely attached to tractor before
raising openers.
2. Retract the opener lift cylinder to fully raise the
openers. Put the tractor circuit control in Neutral to
hold cylinder position.
