SAFETY PRECAUTIONS

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. •Wipe away excess lubricants around bearings and gears. Never lubricate parts in motion. •Always wear approved rubber gloves, and use insulated hooks or tongs when handling trail cable.

Operating Precautions

•Wear hearing protection when exposed to the following noise levels in excess of the period indicated. 8 hours at 90 dBa 4 hours at 95 dBa 2 hours at 100 dBa 1 hour at 105 dBa 30 minutes at 110 dBa 15 minutes at 115 dBa •When in doubt about the noise level, wear approved hearing protection. •Do not attempt to get on or off the machine while it is in operation. Notify the operator prior to any attempt to board/exit the machine. •Do not move or operate the machine without first knowing the location and purpose of all personnel, test or support equipment, on or near the machine. •Do not allow unauthorized personnel on board the machine while in operation. •Use audible signals to warn of machine movements. A signal horn button is provided for this purpose. •Do not propel until the travel route has been cleared of obstructions. •Do not propel the machine on a slope greater than specified in the stability limits shown on the

STABILITY CHART at the end of this section.

•Do not leave the rotary gearbox suspended in the air when leaving the machine unattended. •Prevent trail cable from being dragged on the ground for long distances or at high speeds. •Limit the amount of cable being dragged by the machine. Pulling too much cable will damage both the cable and the machine.
