1 Appendix Great Plains Manufacturing, Inc. 1 Nutri-Pro Spring Plunger pdate NP40 and NP4000 Applicators When you see this symbol, the subsequent instructions and warnings are serious - follow without exception. Your life and the lives of others depend on it! General Information These instructions explain how to update the fold locks on 2-point (semi-mounted) 5-section Nutri-Pro applicators. The kit reduces machine damage risk by adding a hydraulic limiter for the inner fold cylinders, and by providing lock channel capture during transport. One kit updates one applicator. These instructions apply to an installation of: Kit Kit escription A NP4000 PATE KIT. SPG PG efer to igure 1 This kit is not required for pull-type applicators, or any applicators manufactured in 12 or later. If the applicator in question already has the spring plunger assembly 1 on the lock channel, and a stroke control valve on the cylinder, this kit is not required. Some applicators, which do require the spring plunger update, may not require all of the parts in this kit. elated ocuments Have the following manuals available for implement operations and parts identification M NP40 Operator Manual P NP40 Parts Manual M NP40A Operator Manual M NP4000 Operator Manual P NP4000 Parts Manual igure 1 Spring Plunger Components Notations and Conventions eft and ight are facing in the direction of machine travel.

2 2 Great Plains Manufacturing, Inc. ront Page Appendix Spring Plunger pdate Pre-Assembly Preparation Tools equired suitable tractor for raising and unfolding and testfolding 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 C spray paint, or green exterior enamel close to Pantone 356C, upont 262 or PPG Work ocation 1. Move the applicator to a location with: flat, non-combustible surface free of flammable materials adequate illumination clear surface beneath for recovery of any falling or dropped parts 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. High Pressure luid Hazard: elieve pressure before disconnecting hydraulic lines. se paper or cardboard, NOT OY PATS, 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, linding, urning, reezing, isabling and isfigurement Hazards: o not perform maintenance with anhydrous ammonia in the system. ully 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. ire 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: e careful working near row units. Knives and discs may be sharp. Equipment amage isk: isconnect harnesses and ground frame before welding. Connected harnesses or ungrounded frame during welding can result in permanent damage to electronic components M ront Page Appendix
