Foreword This manual is written for an experienced technician. Essential tools required in performing certain service work are identified in this manual and are recommended for use. Live with safety: Read the safety messages in the introduction of this manual and the cautions presented throughout the text of the manual. &causym; This is the safety-alert symbol. When you see this symbol on the machine or in this manual, be alert to the potential for personal injury. Technical manuals are divided in two parts: repair and operation and tests. Repair sections tell how to repair the components. Operation and tests sections help you identify the majority of routine failures quickly. Information is organized in groups for the various components requiring service instruction. At the beginning of each group are summary listings of all applicable essential tools, service equipment and tools, other materials needed to do the job, service parts kits, specifications, wear tolerances, and torque values. Technical Manuals are concise guides for specific machines. They are on-the-job guides containing only the vital information needed for diagnosis, analysis, testing, and repair. Fundamental service information is available from other sources covering basic theory of operation, fundamentals of troubleshooting, general maintenance, and basic type of failures and their causes. This manual may not contain all up-to-date information. All information subject to change without further notice.

Only officially accepted crop protection chemicals and/or liquid fertilizers may be used with this machine, according to the legal directions. The statutory directions are indicated on the packaging and state the purposes for which the chemicals may be exclusively used (for which crops, whether or not in water reclamation areas, etc.). The crop protection chemicals may not be applied for other purposes. Officially accepted crop protection chemicals can be recognized by the authorization number on the packaging.

Chemical Safety
Wear Filtered Respirator
Wear Protective Goggles Crop protection chemicals must be applied with the greatest possible caution, in order to minimize side effects on the environment and your health: Take care when using crop protection chemicals. Use crop protection chemicals in such a manner that the risk of contact is kept to a minimum (work hygienically). This applies to all chemicals, however toxic they may be. Choose chemicals which are the least harmful to your health and which are effectively and quickly decomposed. Always read the packaging label carefully before use. Observe the Statutory Regulations and the Directions for Special Dangers, Safety Recommendations and the User Manual. Use breathing protection apparatus suitable for this type of application according information on packaging label, such as an effective filter mask or a breathing hood or helmet. When preparing the spraying liquid, use a suitable form of breathing protection, a facial screen, gloves, boots and protective clothing suitable for this type of application according information on packaging label. Make sure your head is also protected and do not use clothing also worn for other purposes. Maintain your means of personal protection regularly. Soiled masks may cause skin irritation. Change filters regularly! Refer to type of application and relevant information on packaging label. Choose a safe type of product. The preference must always be for types of products which generate minimum dust and chemicals which are least absorbed by the skin. Choose a safe type of packaging. Provide your employees with effective information on where and when chemicals are to be applied, to prevent them from working in a crop which is still wet from spraying. Do not walk through or work in a crop recently treated. Prepare the spraying liquid outdoors at working height, in order to minimize the risk of spillage. Ensure that wind blows <- Go to Section TOC

sideways when preparing the chemicals. Keep the machine clean. Use cleaners according to the information on chemical packaging label and avoid contact with the crop protection chemicals. When weighing, measuring and preparing crop protection chemicals, use materials kept exclusively for this purpose, such as scales, measuring jugs, funnels, buckets, etc. Clean these materials after each use. Do not prepare more spraying liquid than absolutely essential! Limit the daily working hours spent working with crop protection chemicals to 8 hours. Avoid strong transpiration and heavy physical exertion. Do not drink alcoholic drinks shortly before or after spraying. Never drink, eat or smoke while working with crop protection chemicals. Never clear blocked nozzles by blowing with your mouth. Always pay attention to the safety period when spraying and harvesting. If crop protection chemicals come into contact with the skin, rinse immediately with water. Always wash your hands and face before eating, drinking or smoking. Keep animals and children away from spraying equipment not yet cleaned. Clean this equipment or store it in an area sealed off to unauthorized persons. Wash well with water and soap after working with crop protection chemicals. Maintenance and repairs may only take place following complete cleaning of the machine. Should you or your colleague have problems, visit a doctor immediately and try to discover the identity of the active ingredient. The first measures you can take in the case of the following chemical “injuries” are:
Chemical Injuries - skin, eyes
: rinse with plenty of water
- swallowing
: drink water, not milk
- inhalation
: fresh air
