101 Chapter 2 - Service Service Introduction This Service section is designed to provide you, the customer, with the instructions needed to properly maintain the MEC self-propelled aerial work platform. When used in conjunction with the illustrated Parts section Manual and the Operator s Manual (provided separately), this manual will assist you in making necessary adjustments and repairs, and identifying and ordering the correct replacement parts. All parts represented here are manufactured and supplied in accordance with MEC quality standards. We recommend that you use genuine MEC parts to ensure proper operation and reliable performance. To obtain maximum benefits from your MEC Aerial Work Platforms, always follow the proper operating and maintenance procedures. Only trained authorized personnel should be allowed to operate or service this machine. Service personnel should read and study the Operator s, and the Parts and Service Manuals in order to gain a thorough understanding of the unit prior to making any repairs. Page 97

102 Section 6 - MEC Operator Policy MEC Operator Policy Note:The best method to protect yourself and others from injury or death is to use common sense. If you are unsure of any operation, don t start until you are satisfied that it is safe to proceed and have discussed the situation with your supervisor. Service personnel and machine operators must understand and comply with all warnings and instructional decals on the body of the machine, at the ground controls, and platform control console. MODIFICATIONS OF THIS MACHINE FROM THE ORIGINAL DESIGN AND SPECIFICATIONS WITHOUT WRITTEN PERMISSION FROM MEC ARE STRICTLY FORBIDDEN. A MODIFICATION MAY COMPROMISE THE SAFETY OF THE MACHINE, SUBJECTING OPERATOR(S) TO SERIOUS INJURY OR DEATH. MEC s policies and procedures demonstrate our commitment to Quality and our relentless ongoing efforts towards Continuous Improvement, due to which product specifications are subject to change without notice. Any procedures not found within this manual must be evaluated by the individual to assure oneself that they are proper and safe. Your MEC Aerial Work Platform has been designed, built, and tested to provide many years of safe, dependable service. Only trained, authorized personnel should be allowed to operate or service the machine. MEC, as manufacturer, has no direct control over machine application and operation. Proper safety practices are the responsibility of the user and all operating personnel. If there is a question on application and/or operation, contact MEC Aerial Work Platforms: MEC Aerial Work Platforms 1401 S.

103 Section 7 - Safety Symbols & General Safety Tips Safety Symbols & General Safety Tips MEC manuals and decals use symbols, colors and signal words to help you recognize important safety, operation and maintenance information. RED and the word DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. ORANGE and the word WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. YELLOW with alert symbol and the word CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. YELLOW without alert symbol and the word CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in property damage. GREEN and the word NOTICE Indicates operation or maintenance information. Regular inspection and constant maintenance is the key to efficient economical operation of your aerial work platform. It will help to assure that your equipment will perform satisfactorily with a minimum of service and repair. The actual operating environment of the machine governs the inspection schedule. Correct lubrication is an essential part of the preventative maintenance to minimize wear on working parts and ensure against premature failure. By maintaining correct lubrication, the possibility of mechanical failure and resulting downtime is reduced to a minimum. Never leave hydraulic components or hoses open. They must be protected from contamination (including rain) at all times. Never open a hydraulic system when there are contaminants in the air. Always clean the surrounding area before opening hydraulic systems. Use only recommended lubricants. Improper lubricants or incompatible lubricants may be as harmful as no lubrication. Watch for makeshift fixes which can jeopardize safety as well as lead to more costly repair. Page 99
