IMPORTANT NOTE
DANGER:
THIS MANUAL PROVIDES INFORMATION AND DATA FOR THE MAINTENANCE AND OPERATION OF THIS MACHINE. ALL ELECTRICAL EQUIPMENT MUST BE SERVICED BY QUALIFIED INDIVIDUALS WHO HAVE BEEN PROPERLY TRAINED TO WORK WITH HIGH VOLTAGE SYSTEMS, VARIABLE FREQUENCY AC DRIVES, AND/ OR WARD LEONARD LOOP DC DRIVES. FAILURE TO COMPLY COULD RESULT IN PERSONAL INJURY OR DEATH.
DANGER:
DO NOT ATTEMPT MECHANICAL OR ELECTRICAL MAINTENANCE ON THIS MACHINE WITHOUT A FULL UNDERSTANDING OF EACH COMPONENT’S OPERATION AND FUNCTION. COMPONENTS UTILIZING ELECTRICAL POWER, AIR PRESSURE, HYDRAULIC PRESSURE AND COMPRESSION OR TENSION SPRINGS FOR OPERATION MUST BE DEACTIVATED AND ISOLATED PRIOR TO DISASSEMBLY.
The FEEDER CABLE must contain a provision for a ground connection, especially whenever 2,300 volts or greater are used. At the substation, the power line must terminate (see paragraph on ground circuits) to a suitable permanent ground. At the machine, the power line must securely terminate through a bolted connection to the machine frame. This provides a constant ground for the machine and its electrical equipment. Failure to provide this adequate ground endangers employees and equipment.
THE NEED FOR A POWER LINE GROUNDING CIRCUIT ADEQUATE FOR THE MACHINE CANNOT BE OVEREMPHASIZED. Without a good grounding system, high voltages exist between the machine and the ground. The portable trail cable and power lines supplying electric energy to the machine must have a ground wire, ample in capacity, running parallel to the main wires over the entire distance from the transformer to the machine. A suitable grounding system must be used at the transformer. Consult your local electrical supplier for details.
DANGER:
DUE TO THE INHERENT DANGERS IN THE OPERATION OF HIGH VOLTAGE ELECTRICAL EQUIPMENT, A SAFE GROUNDING SYSTEM IS REQUIRED THAT INCLUDES GROUND CONDUCTORS IN THE CABLE, A NEUTRAL GROUNDING RESISTOR, AND RELATED RELAYS AND SWITCHGEAR. A GROUND CONTINUITY CHECK SYSTEM IS ALSO RECOMMENDED.

SAFETY PRECAUTIONS
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 man 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.
•Perform functional tests of all safety circuits.
•Allow electrical inspection and maintenance to be performed only by a qualified electrician.
•Use extreme caution when working around drilled holes.
Maintenance Precautions:
•Do not wear rings, wristwatches or loose fitting clothing when working on machinery. They could get caught on moving parts causing serious injury.
•Always wear a safety belt or harness when the danger of falling exists.
•Always have a second person to monitor the lifeline when working in confined spaces.
•Do not start an engine indoors unless adequate exhaust ventilators are provided and in operation.
•Never utilize the machine air or hydraulic systems for support when working on the machine. Deactivate or isolate the entire 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, pipe arms, etc.) Always work within the limitations of the equipment being utilized.
•Be sure heavy items are properly rigged and supported from cranes or hoists before removing supporting members from the machine.
•Utilize guide lines or ropes to minimize the swing of suspended heavy components.
•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.
•When disassembling a machine, be sure to use safety stands and adequate cribbing to prevent tipping or rollover of components.
•When using an oxy/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.
•Use pullers to remove bearings, bushings, gears, cylinder sleeves, etc. when applicable. Use hammers, punches and chisels only when absolutely necessary. Always be sure to wear safety glasses.
•Use extreme caution when using compressed air to dry parts. Use approved air blowguns, 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.
•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.
