INTRODUCTION
The information contained in this manual provides guidance to all persons who care about the operation and maintenance of this machine. Needed data for operation, lubrication, adjustments and other tasks supplied in the various sections permits accurate operation and service. All enclosed specifications agree with the Marion Power Shovel Engineering Department. This information allows for quality maintenance when followed exactly.
This Manual is NOT a Parts Book. Do not use it to order parts. You have been supplied with a separate, detailed Parts Book. Please read carefully the instructions in the front of it. All parts are listed by group number with items and part numbers for this SPECI FIC machine. Please order the correct parts in exact quantity. Parts ordered by mistake and returned are subject to a Company rehandling charge. RIGHT and LEFT HAND PARTS on the upper frame correspond to the operator's hands at the controls as he faces the bucket. Please state the correct machine SERIAL NUMBER in any conversation or correspondence. Records of each machine are filed by serial number. Given this number, the specific design and original equipment check is accurate and quick.
ADDED INFORMATION, when required, not found in this Manual or the Parts Book may be obtained from Marion Power Shovel Company, Inc. at Marion, Ohio 43302.
SERVICE and LABOR CHARGES are NOT accepted unless previously authorized by the Company in writing.

SAFETY SUGGESTIONS
The operator controls the machine and its usefulness. The crew alone thinks for it. Safety, constantly in mind, prevents accidents. Develop good habits. Everyone has bad habits, bUJ try to erase them quickly. Cleanliness and safety go together. A clean machine is easier to operate, inspect and maintain.
READ and OBSERVE All warning signs, they're placed for your health and safety.
KNOW the location of fire extinguisher.
DO NOT START machine without a FULL tank of air pressure.
DO NOT LEAVE the controls without pushing the STOP BUTTON marked "EXCITATION", turning BOTH brake switches to "SET" and automatic drill control lever to the center detent position.
DO NOT SERVICE or lube moving parts.
PLEASE READ carefully this Manual and Parts Book.
PLEASE LUBE regularly.
PLEASE CREATE A SYSTEMATIC maintenance procedure and follow it.
PLEASE WATCH clearance when lowering mast.
PLEASE OPERATE machine on as near level ground as possible.
PLEASE KEEP safe operating procedures in mind at All times.
CAUTION IS THE BY-WORD. Develop a feel for the machine. Try to sense failure before it arrives. Take that extra second to look again at something that seems out of place. A paint chip or bubble may be an early warning. A slight hiss may indicate a growing air leak. It's much easier to tighten a packing nut than shutdown for packing repair.
PROPER LY GROUND the power source.
WATCH AI R system performance.
CHECK pull down chains for early signs of wear or failure that may cause permanent damage.
CHECK LIMIT switches for proper operation.

CHECK OVERLOAD and thermal breakers.
MAl NTAI N correct supply of lubricant.
MAINTAIN CLEAR walkways.
LOOK FOR loose bolts and locking devices.
KEEP FLOORS CLEAN and free of oil and grease.
WIPE AWAY excess grease and oil around bearings and gears.
KEEP hands, feet and clothing away from moving parts.
PROMPTL Y REPLACE all guards, inspection doors, access covers and other safety features after inspection or repair.
NEVER attempt electrical repair, unless qualified.
HIGH VOLTAGE power lines reguire using EXTREME CAUTION.
Open pit mining equipment undergoes tremendous shock and stress. Marion's design considers these loads. This machine, built with an ample reserve of power and strength, will meet the demands of its task. Marion's engineers cannot foresee the conditions imposed by abuse, neglect and mismanagement. These factors damage any piece of equipment more than years of continuous operation and normal wear. Care, sound judgement and reason govern the economic need in the operation of power equipment.
Downtime exists, but an ongoing program of inspection and evaluation minimizes it. Awareness of unusual conditions generally warns personnel before breakdown occurs. Normal wear of machinery parts escapes definition. Parts do not suddenly expire. Wear takes place at varying degrees over time. Constant checking indicates a wear pattern. An alert mainlenanee crew checks ALL structural members for evidence of stressed, broken or loose items. Minor cracks occur in steel structures. it's true of ALL macllines. This is NOT SERIOUS when weld repaired while SMALL. Cold weither causes faster expansion and brittleness than warm weather. Early detection and quick repair prevents failure. A stretch, bend or defect often shows up in condition of surface paint. A collection of dust along a line may indicate a crack in the metal. Look closely at areas around openings where angles are Gut out. Also check gusset connections and points where thin and heavy metals join. The good crew watches for loose bolts, nuts, cap screws, lock washers and other locking devices. Rod bolts are important too. Signs of scuffed paint, worn or brigl"lt spots next to any part indicate movement and becomes second nature to most personnel. Retighten ALL bolts shortly after initial start up. Grease and oil stClins often indicate problems. Perhaps just poor housekeeping, but at least something is wrong.

Replacement and maintenance schedules may conform to planned shutdowns. Lack of proper lube, poor adjustments and abuse cause and speed up wear. These facts show up as the MAl N reasons for breakdown. If any part shows wear or distortion beyond expected normal wear, order replacement and quickly install. The cost of parts is nothing when cO,mpared to breakdown cost and loss of man hours and production.
production machines operating 24 hours, 7 days every week deserve an 8 hour inspection and cleaning every 10 days. Cleaning before inspection eliminates dirt and dust falling into machinery parts when inspection plates and covers are removed.
A solvent makes removal of the accumulation of oil and grease in the machinery house easier.
Run the rotary gearbox and propel gearbox in each direction. Sound here may indicate damaged teeth on the gears. Check gearbox for oil leakage and visually inspect all seals. Check oil level with dipstick.
Check rotary gearbox alignment in hoist and pull down and examine the guide rollers for wear. Check for side to side cocking of gearbox in pull down. This could indicate an unequal number of links in the two pull down chains. Examine chains for excessive wear or failure.
Examine crawler belt for worn pins and broken keeper bolts. Check for cracked or broken shoes. Examine crawler drive sprocket for cracking or excessive wear. Check propel chain for exceSsive wear or failure. Examine hydraulic hoses for early signs of failure.
Check oil level in hydraulic tank, check dirty filter indicators at full system flow. Check gauges on tank for low charge pressure and high suction line vacuum.
Check and clean if necessary the inlet filter for the main air compressor. Check for proper operation of the three blutterflyvalves. Examine the main air piping for leaks. Check operationof the force feed rubricator. Check V-b'elt tension and tighten or replace belts if needed.
Examine and readjust, if needed, the hoist pull down brakes. Look at the condition o'f brake lining. Examine condition of propel brakes. Check auto-lube system for loose or broken fittings or injectors,
Secure ALL guards and safety features in place. DISCONNECT POWER SOURCE with machine shut down so electrical crew may adequately clean and inspect motor generators and electrical cabinets. NOTE any discolored electrical parts is a sign of overheating. In humid areas, look for fungus and mildew. Dry compressed air at LOW pressure works well for dust removal. Clean corrosion from parts, joints and connections. Retighten, where needed, any loose connections and terminals. Use of proper tool here eliminates broken
