IMPORTANT SAFETY INFORMATION :
- Most accidents involving product operation, maintenance and repair are caused by failure to observe basic safety rules or 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. Read and understand all safety precautions and warnings before operating or performing lubrication, maintenance and repair on this product.
- Basic safety precautions are listed in the “Safety” section of the Service or Technical Manual. Additional safety precautions are listed in the “Safety” section of the owner/operation/ maintenance publication. Specific safety warnings for all these publications are provided in the description of operations where hazards exist.
- WARNING labels have also been put on the product to provide instructions and to identify specific hazards. If these hazard warnings are not heeded, bodily injury or death could occur to you or other persons. Warnings in this publication and on the product labels are identified by the following symbol.
FOREWORD :
How to Use This Manual :
- This manual provides information for servicing the skid steer loader. All service procedures are broken down into detailed steps, listed in their recommended sequence. The manual uses both photographs and drawings to help locate and itemize components.
- The table of Contents on the preceding pages is your best tool for finding the service procedure you need. Be certain to observe all Safety information included in these pages. General Precautions for Disassembly Preparations Before Disassembly
- 1. Wash the machine before moving it to into the repair shop. Prior to moving the machine into the repair shop remove dust and dirt thoroughly by washing the machine. Dirt brought into the shop will degrade the cleanliness of the parts handled in the shop, will produce scratches, and can contaminate the inside of reassembled units.
- 2. Checking and inspection before disassembly. Before attempting to disassemble, check thoroughly to determine the cause of the problem, and record it. This will not only prevent needless disassembly and losses from needless replacement parts and man-hour costs, but will also prevent repetition of the same problem. It is important to keep records of problems and replacements in order to advise serviceman how to prevent trouble.
Items to be checked and recorded are as follows:
- Model, machine serial number and service meter readings.
- Reason for disassembly.
- Components replaced. Check for symptom, location and cause of problem. If necessary, try repeating the same problem.
- Amount of dirt in air cleaner elements and air leakage.
- Oil levels in the engine oil pan and status of oil (viscosity, color and mixed impurities).
- Water mixed in the oil and oil leakage.
- Clogging of the oil filter element.
