SAFETY PRECAUTIONS

AThis safety alert symbol is used here and throughout this manual to call your attention to instructions concerning your personal safety. Carefully read and follow these instructions and observe all safety and danger, and caution graphics mounted on various areas of the machine.

Be certain anyone servIcing this machine is aware of these SAFETY PRECAUTIONS. In the event you question your ability to safely perform any of the enclosed maintenance and operational procedures contact your regional Marion service representative or the factory.

The following defines distinctions between safety instructions. In all these definitions the safety alert signal is used.

ADANGER:

ACAUTION:

Denotes extreme intrinsic hazard which exists and could result in high probability of death or irreparable injury if proper precautions are ignored. Denotes a reminder of safety practices or directs attention to unsafe practices which could result in personal injury if proper precautions are ignored.

An example of a safety alert symbol and special safety instructions is shown below.

ADANGER: Inherent danger exists in the operation of any high voltage electrical equipment. A safe grounding system includes ground conductors in the power cable, a neutral grounding resistor and related relays and switchgear. A ground continuity check system is required by law in many parts of the world.

Operating, maintaining or servicing this machine can be dangerous unless performed properly. Each person must satisfy himself and his employer that he is alert and has the necessary skill and information, proper tools and equipment, and all methods are safe and correct. Factory service representatives and specialists are available to provide additional information or technical assistance.

SAFETY PRECAUTIONS - continued

The operator must be alert, physically fit, and free from the influence of alcohol, drugs, or medications that might effect his eyesight, hearing or reactions.

Safety must always be the operator's most important concern. He must refuse to operate when he knows it is unsafe, and consult his supervisor when safety is in doubt.

The owner and/or operator must replace any and all safety and warning product graphics if they are defaced or removed from the machine.

Before doing any work on the machine, lock out or remove electric power supply from the machine and tag it so personnel are aware that someone is working on the machine.

Keep hands, feet, clothing away from rotating parts.

Before walking machine, place trail cable in a safe position.

Think before you act. Carelessness is one luxury the serviceman cannot afford.

Do not wear rings, wrist watches or loose fitting clothing. They could catch on moving parts causing serious injury. Never adjust and/or service a machine in bare feet, sandals or sneakers. Never work on rotating or moving machinery.

Always wear safety glasses when using a hammer, chisel or other tools that may cause chips to fly.

Excessive or repeated skin contact with sealants or solvents may cause skin irritation. In case of skin contact, remove sealant or solvent promptly by washing with soap and water.

Always use a safety bar to block air or hydraulic operated cylinders. Never rely on the machine air or hydraulic systems to hold when working on machines. An air or hydraulic line or cylinder could fail or someone could accidently strike the control levers causing tha equ ipment to fall.

Equipment must be level on ground at all times during machine servicing and periods of idleness.

Cranes and hoists must be of sufficient capacity to lift the heavier components (gear cases, dipper/bucket, boom, etc.) and have an ample safety margin.

Be sure heavy items are properly supported from cranes or hoists before removing support· ing members from machine.

SAFETY PRECAUTIONS - continued

Have sufficient service personnel available when removing or installing large heavy items to maintain control at all times.

Always use safety stands in conjunction with hydraulic jacks or hoists. Do not rely on the jack or hoist to carry the load, they could fail.

Use safety catch on all hoist hooks. Do not take a chance, the load cou Id sl ip off of the hook.

If a heavy item begins to fall, let it fall, don't try to catch it.

When disassemblingmachines, be sure to use safety stands and adequate cribbing to prevent tipping or rollover of components.

Keep work area organized and clean. Wipe up oil or spills of any kind. Keep tools and parts off of the ground. Eliminate the possibility of a fall which could result in a serious injury.

Floors, walkways and stairways must be clean and dry. After draining operations be sure all spillage is cleaned up. Electrical cords and wet metal floors make a dangerous combination.

Check all wire ropes for telltale signs of early wear or failure. Look for and secure any loose bolts or locking devices.

Use extreme caution while working near any electrical lines or equipment whether it be high or low voltage. Never attempt electrical repairs unless qualified. Check limit switches for proper operation.

When using an acetylene torch, always wear welding goggles and gloves. Keep a "charged" fire extinguisher within reach. Be sure the acetylene and oxygen tanks are separated by a meta I sh ield and are cha ined to the cart. Do not weld or heat areas near transformers or electrical cabinets and utilize proper shieldingaround lubrication lines.

Use pullers to remove bearings, bushings, gears, cylinder sleeves, etc. when applicable. Use hammers, punches and chisels only when absolutely necessary. Then, be sure to wear safety glasses.

Be careful when using compressed air to dry parts. Use approved air blow guns, do not exceed 207 kPa (30 psi), wear safety glasses or goggles and use proper shielding to protect everyone in the work area.

Be sure to promptly reinstall safety devices, guards or shields after adjusting and/or servicing the machine.

SAFETY PRECAUTIONS - continued

After servicing, be sure all tools, parts or servicing equipment are removed from the machine.

Protective eye goggles should be worn at all times when working on the air conditioning system. Work on the air conditioning system only in a well ventilated area.

Wipe away excess lubricants around bearings and gears. Never lubricate parts in motion.

Operate machine on level ground and be continuously aware of swing clearance. Never hold a load longer than needed in dump cycle. Use swing brakes only when machine is stopped.

PREVENTIVE MAINTENANCE -

Machine downtime is costly to owners in lost production. Preventive maintenance is the task of identifying, replacing or repairing machine components before they fail so that downtime is minimized.

ACAUTION: Do not perform inspection activities while machine is in operation.

Due to variations in operational wear rates of machine components and machine application conditions, component life cycles are different. A scheduled program of machine inspection with accurate record keeping can identify machine component and their rates of wear.

A continuous careful inspection routine can spot unusual conditions or fatiguing components before a failure occurs. Maintenance, repair and component replacement schedules should conform to schedu led machine shutdowns. If during daily, weekly or monthly inspection routines any part shows wear or distortion beyond expected normal patterns replace them with genuine Marion parts at the next scheduled maintenance interval. The cost of parts is small when compared to unscheduled breakdowns with their resulting lost manhours and machine production.

Machines which operate 24 hours, 7 days per week should have a scheduled 8-hour preventive maintenance period each 7-day period. See Section 8 for recommended inspection schedules.

Preventive maintenance inspection procedures listed below are suggested as an example of specific typical inspection activities. Each owner should establish his own preventive maintenance inspection schedule based on machine application conditions and production cycle.

ACAUTION: Maintenance and operating personnel should be aware of mechanical and electrical hazards inherent in servicing this machine.

INSPECTION CHECKLIST

Check condition of rope sheave groovesand bearings

Test all hold down bolts with impact wrenches

Check rope guides and bails for wear

Inspect all rope for broken wire or loss in diameter

Check auto-lube system for loose or damaged fittings and injector condition

Inspect dipper/bucket for cracks

ADANGER: Remove electrical power from machine whenever inspection of center journal, collector rings, rails or roller circle is performed. Use extreme care in removing guards and protective devices.
