Pre-Assembly Preparation
Tools Required
• suitable tractor for raising and unfolding and test-
folding applicator
• clean buckets for draining hydraulic fluid
• light/white tape and marker for identifying hoses
• basic hand tools
• (most cases) wire or rod welder, tarps and fire
extinguisher; two or more 7 inch (18 cm) clamps
• (most cases) portable cut-off saw or torch (and fire
extinguisher), grinder and sanding equipment
• (most cases) Great Plains 821-001C spray paint, or
green exterior enamel close to Pantone 356C,
DuPont 262 or PPG 43817
Work Location
1. Move the applicator to a location with:
Prepare Applicator
2. If the applicator is an anhydrous model, perform a
system discharge before commencing work. This is
particularly important if the update is done indoors.
• flat, non-combustible surface free of flammable
materials
• adequate illumination
• clear surface beneath for recovery of any falling or
dropped parts
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing
serious injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
Only trained personnel should work on system hydraulics
Anhydrous Models - Suffocation, Blinding, Burning,
Freezing, Disabling and Disfigurement Hazards:
Do not perform maintenance with anhydrous ammonia in the
system. Fully discharge the system of NH
3
liquid and vapor
before working on the implement.
Crushing Hazard:
When disconnecting hoses at cylinders, do not disturb
restrictor orifice plates. These plates reduce wing falling rate
in the event of catastrophic hydraulic failure. Omitting a plate
could result in serious injury or death beneath a falling wing.
Fire Hazard:
This update may require welding and/or cutting thick metal.
Sparks are likely. Perform the work clear of flammable
materials. Wear suitable protective equipment. Allow hot parts
to cool before continuing work.
Crushing and Sharp Object Hazards:
Be careful working near row units. Knives and discs may be
sharp.
Equipment Damage Risk:
Disconnect harnesses and ground frame before welding.
Connected harnesses or ungrounded frame during welding
can result in permanent damage to electronic components.
