- WARNING-
DUE TO THE' DANGERS INHERENT IN THE OPERATION OF ANY mGH VOLTAGE ELECTRICAL EQUIPMENT, A SAFE GROUNDING SYSTEM SHOULD BE USED. SUCH SYSTEM SHOULD INCLUDE GROUND CONDUCTORS IN THE CABLE, A NEUTRAL GROUNDING RESISTOR AND RELATED RELAYS AND SWITCHGEAR. A GROUND CONTINUITY CHECK SYSTEM IS ALSO RECOMMENDED.
READ AND OBSERVE ALL warning signs, they're placed for your health and safety.
In the event you doubt, for any REASON. your ability to safely perform any of the enclosed maintenance and operational procedures as they refer to your machine. please contact Marion Power Shovel Company. Inc.
This manual has been prepared for the standard production machine. Any deviation due to advanced engineering design, optional equipment or the particular requirements of this machine may not be covered.
Additional information that is required will be furnished as soon as such information is available.

GENERAL INFORMATIDN
INTRODUCTION
This manual is provided for the guidance of all persons who operate, lubricate, adjust or maintain the Marion 8050 Walking Dragline. The information was prepared with the purpose in mind of furnishing accurately and concisely all the data necessary to the operation and servicing of this machine.
All information, measurements, and specifications herein are in accord with the Marion Power Shovel Engineering Department and should be strictly adhered to in all work on this machine.
PARTS BOOK
TillS MANUAL IS NOT A PARTS BOOK AND SHOULD NOT BE USED IN ORDERING PARTS.
You have been furnished detailed Parts Books which list all parts by group numbers with items and part numbers for your specific machine.
Read carefully the instructions in the front of the Parts Book for ordering parts.
SERIAL NUMBER OF MACHINE
Be sure that the serial number of the machine is given in any letters, telegrams, orders or other communications. Records for each individual machine are filed by serial number and if this number is available, the design and original equipment can be quickly and accurately checked.
RIGHT AND LEFT HAND PARTS
On the upper frame, right hand (R. H. ) and left hand (L. H. ) correspond to the operator I s right and left hands when he is facing the bucket while at the operator 1 s controls.
ORDERING PARTS
The Parts Book covering this machine gives complete information on how to order parts. Order carefully so that the right parts in the right quantities can be furnished. Wrong parts, ordered by mistake, which are returned to the company are subject to a rehandling charge.
FURTHER INFORMATION
If further information is required which is not found in the Manual or in the Parts Books, communicate with the Marion Power Shovel Company, Inc., at Marion, Ohio.
CHARGE FOR SERVICE, LABOR, ETC.
No charges for service or labor are accepted unless the work has been previously authorized by the company in writing.
STANDARD WARRANTY
Marion Power Shovel Company, Inc. guarantees the equipment manufactured by it to be free from defects in material and workmanship under normal use and service, its obligation under this warranty being limited to making good at its factory any part or parts thereof manufactured by it which shall, within six (6) months after delivery to Buyer, be returned to it, with transportation charges prepaid, and which its examination shall disclose to its satisfaction to have been thus defective, this warranty being expressly in lieu of all warranties, express or implied, and of all other obligations or liabilities on Marion Power Shovel Company's part .
.
Marion Power Shovel Company, Inc. shall not be held responsible or liable in any event for special or consequential damages, arising from any cause whatsoever, and Buyer agrees to indemnify and save Marion Power Shovel Company, Inc. harmless therefrom.
Marion Power Shovel Company, Inc. makes no guaranty or warranty, express or implied, as to adequancy, fitness, quality, or performance of any machinery, equipment, apparatus or accessories not manufactured at its own factory, which are subject only to such guaranty as may be made by the respective manufacturers thereof. 8050
The company reserves the right to improve or change the design of its products and specifications thereof and the company shall incur no liability thereby or any obligations to install such improvements on products previously sold.
SAFETY PRECAUTIONS
The usefulness of this machine depends entirely on the man at the controls. The operator is its brains. He must think safety and work safely.
Neatness and safety go hand in hand. Good housekeeping habits should be developed.
1. Keep the floor clean and free from oil and grease.
2. Keep the walkways clean, clear, and free from obstructions.
3. Prevent the accumulation of grease and oil around bearings and gears. Grease and oil collect and hold grit and dirt which work into finely machined parts.
4. A clean machine is easier to operate - easier to inspect - easier to service.
5. Keep hands and clothing away from moving parts.
6. Replace guards, inspection plates, access covers, etc., promptly after reason for removal is accomplished.
Strip mining equipment is subject to tremendous stresses arid shock loads. These stresses are thoroughly studied and considered in the design and building of Marion equipment.
This machine is built with an ample reserve of power and strength and is, well fitted to meet the demands of its task.
However, the Marion engineers cannot foresee the conditions imposed by abuse, mismanagement and neglect. These factors are more damaging to any piece of equipment than years of continuous operation and normal wear.
8are, sound judgment and reason are an economic necessity in the operation of power equipment.
DO
1. Carefully read this Manual and Parts Book.
2. Lubricate regularly. Establish a systematic procedure and stick to it.
3. When lubricating, check all bolts, nuts, lock nuts and cotter pins.
4. Keep loose objects in tool box or in suitable enclosure or cabinet.
5. Always replace guards.
6. Always watch your clearance when swinging.
DON'T
1. Service or lubricate parts that are moving.
2. Leave the load suspended in air.
DON'T APPLY SWING BRAKES WHILE MACHINE IS ROTATING, EXCEPT IN EMERGENCY.
PREVENTIVE MAINTENANCE
Open pit mining machinery is required to operate in the most adverse conditions of any industrial machines.
Conditions are rarely ideal. It is always too hot, too cold, too dry or too wet. The air is always saturated with fine abrasive dust. High production schedules tax both men and machines.
Downtime and delays are intolerable. Downtime can not be eliminated, but it can be kept to a minimum by a progressive and conscientious program of preventive maintenance.
Aside from regular lubrication, proper and accurate adjustments, the personnel should be aware of any deviation from the normal, which could be evidence of impending breakdown or components failure.
The maintenance people should inspect, during their rounds, all structural members for evidence of stressed, broken or loose parts. Evidence of a member stretching, bending, or deflecting can often be determined by the conditions of the surface paint. Stressed parts will show wrinkles or waves in the paint or check marks.
Breaks or chips in the surface or a collection of dust along a line may indicate a crack in the metal. Pay particular attention to those areas around openings where corners or angles are cut out, at the ends of gussets or at brace connections and at transitional points where heavy and thin parts join.
Stress in a monolithic structure may travel some distance from the damaged area and manifest itself at a remote point in some seemingly unrelated place.
The maintenance people should check all bolts, nuts, cap screws and rod bolts. Lock washers and other locking devices must be in place.
Be sure that bolted and assembled parts are tight. Evidence of movement may be detected by signs of scuffed paint, worn or bright spots adjacent to the part. Often a slight movement of parts that can 't be seen with the eye can be felt with the finger tip when the machine is working.
Grease or oil stains that are unaccountable, or out of place are often evidence of a fault.
If any part or .parts shows wear or distortion beyond that expected from normal wear, replacement part should be made available at once and promptly installed. The cost of prompt replacement of parts is negligible compared to the cost of breakdown - loss of production and man hours.
