Chassis Service Manual.
- Most accidents involving product operation, maintenance and repair are caused by failure to observe basic safety rules and precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards.
- This person should also have the necessary training, skills and tools to perform these functions properly. Improper operation, lubrication, maintenance or repair of this product can be dangerous and could result in injury or death. Do not operate or perform any lubrication, maintenance or repair on this product, until you have read and understood the operation, lubrication, maintenance and repair information. Safety precautions and warnings are provided in this manual and on the product.
- If these hazard warnings are not heeded, bodily injury or death could occur to you or other persons. The hazards are identified by the “Safety Alert Symbol” and followed by a “Signal Word” such as “CAUTION” or “WARNING” as shown below. WARNING The meaning of this “Safety Alert Symbol” is as follows: Attention! Become Alert! Your Safety is involved.
- The message that appears under the warning explains the hazard and can be either written or pictorially presented. Operations that may cause product damage are identified by NOTICE labels on the product and in this publication. Mitsubishi Caterpillar Forklift America Inc. (MCFA) cannot anticipate every possible circumstance that might involve a potential hazard.
- The warnings in this publication and on the product are therefore not allinclusive. If a tool, procedure, work method or operating technique not specifically recommended by Mitsubishi Caterpillar Forklift America Inc. (MCFA) is used, you must satisfy yourself that it is safe for you and others. You should also ensure that the product will not be damaged or made unsafe by the operation, lubrication, maintenance or repair procedures you choose.
- The information, specifications, and illustrations in this publication are on the basis of information available at the time it was written. The specifications, torques, pressures, measurements, adjustments, illustrations, and other items can change at any time. These changes can affect the service given to the product. Obtain the complete and most current information before starting any job. Mitsubishi forklift truck dealers have the most current information available
