SAFETY ALERT SYMBOLS

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, DANGER, and CAUTION graphics mounted on various areas of the machine.

Be certain anyone servicing this machine is aware of these SAFETY SYMBOLS and their definition. 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:

Denotes extreme intrinsic hazard which exists and could result in high probability of death or irreparable injury if proper precautions are ignored.

ACAUTION:

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 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 switch-gear. A ground continuity check system is required by law in many parts of the world.

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

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 most important concern. Consult your supervisor when safety is in doubt.

SAFETY PRECAUTIONS

- 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, a qualified electrician must lock out or remove the electric power supply from the machine and tag it so personnel are aware that someone is working on the machine.

- Do not start an engine indoors unless adequate exhaust ventilators are provided. Once an engine is running, move the machine outdoors as soon as possible.

- Keep hands, feet, and clothing away from rotating parts.

- Do not move or operate the machine without knowing the location and purpose of all personnel, plus test or support equipment, in or near the machine.

- Think before you act. Carelessness is one luxury the service man cannot afford.

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

- 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.

- Never utilize the machine alr or hydraulic systems for support when working on the machine. Deactivate and isolate the system prior to performing maintenance.

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

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

- Be sure heavy items are properly supported from cranes or hoists before removing supporting members from machine.

- 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 could slip off of the hook.

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

- When disassembling machine, 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 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 metal shield and are chained to the cart. Do not weld or heat areas near transformers or electrical cabinets and utilize proper shielding around 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 30 PSI (207 kPa), 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.

- After servicing, be sure all tools, parts or servicing equipment are removed from the machine, or secured in an appropriate storage area.

- 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 constantly aware of swing clearance. Never hold a load longer than needed in the dump cycle. Use swing brakes only when machine is stopped.

FIRE PREVENTION

- Always have a "charged" fire extinguisher on hand and know how to use it. Inspect and service the extinguisher as indicated on its instruction plate.

- DO NOT smoke while handling flammables or when near batteries.

- Inspect all lines, tubes, and hoses carefully. Tighten all connections to the recommended torque. See the Visual Inspection Schedule for the walk around inspection procedure.

- Loose or damaged lines, tubes, and hoses, which leak, can cause a fire.

- Make certain that all clamps, guards, and shields are replaced correctly so as to prevent vibration and the rubbing of one part against another which might result in heat build-up during operation.

- DO NOT carry flammable fluids such as gasoline or solvents on board the machine.

- DO NOT over-bend or strike pressurized hose lines. DO NOT install bent or damaged lines, tubes, or hoses. Replace them with new immediately.

- DO NOT start the machine or move any of the controls if a warning tag is attached to the controls or the start panel.

- Keep all cleaning rags properly stored. DO NOT discard them into a pile on board.

- Keep all structural frame compartments, walkways, and work areas clean and free of lubricant residue.

- NEVER weld, burn, or perform service on the machine alone.

- If a motor or other component is running hot, shutdown the machine until it has cooled and/or the cause eliminated.
