CAT Bucyrus 495HR2 Mining Shovel Maintenance Manual SN 141320 PDF DOWNLOAD
GENERAL INFORMATION
- This manual is designed to assist the owner in the operation and maintenance of this machine.
- By following easy to understand step-by-step procedures the operators and maintenance personnel can perform all tasks in a safe manner.
- When a systematic and thorough maintenance/service procedure is used for this machine, a minimum of unplanned downtime and more reliable operation will result.
- Throughout this section, and the remainder of the manual, the use of the terms “LEFT, RIGHT, FRONT, and REAR” refer to machine locations as viewed by the operator sitting in the operator’s seat in the cab. THIS MANUAL IS NOT THE PARTS BOOK, and cannot be used as reference material to order parts. A separate, detailed parts book has been supplied for this purpose.
GENERAL PRECAUTIONS
• The employment of qualified maintenance personnel, through a scheduled maintenance program, is the best way to minimize machine downtime and maximize productivity of equipment.
Keep hands, feet and clothing away from rotating parts.
• Wear a hard hat, safety shoes and protective lenses at all times.
• Replace any and all safety and warning placards if they are defaced or removed from the machine.
• Think before you act. Carelessness is one luxury the service person cannot afford.
• Excessive or repeated skin contact with sealants or solvents may cause skin irritation. In case of skin contact refer to the Material Safety Data Sheet (MSDS) for that material and the suggested method of cleanup.
• Inspect safety catches (keepers) on all hoist hooks. Do not take a chance, the load could slip off of the hook if they are not functioning properly.
• If a heavy item begins to fall, let it fall, don’t try to catch it
. • Keep your work area organized and clean. Wipe up oil or spills of any kind immediately. Keep tools and parts off of the ground. Eliminate the possibility of a fall, slipping or tripping.
• Floors, walkways and stairways must be clean and dry. After fluid draining operations be sure all spillage is cleaned up.
• Electrical cords and wet metal floors make a dangerous combination.
• Regularly inspect for any loose bolts or locking devices and properly secure them.
• Use extreme caution while working near any electrical lines or equipment whether it be high or low voltage. Never attempt electrical repairs unless you are qualified
. • Check limit switches for proper operation.
• After servicing, be sure all tools, parts or servicing equipment are removed from the machine and secured in an appropriate storage area.
• Mechanical Brakes are designed for use as static holding brakes only. Use as a motion (dynamic) brake in emergency situations only.
• Use proper interior and exterior lighting.
• Install and maintain proper grounding and ground fault protection systems.
• Allow electrical inspection and maintenance to be performed only by a qualified electrician
