1.3 M ANUAL PURPOSE

This manual provides information and specifications required for the safe operation andcontrol of the drawworks. Refer to the operation and maintenance, and installationmanuals for more information.

1.4 GENERAL S AFETY

Follow these additional safety principles when operating the drawworks:

Any personnel that install, operate, or service this equipment must have appropriatetraining and required certification.

Comply with all approved safety procedures when installing, operating, or servicing this

equipment.

To prevent contact with moving parts, make sure that all guards are in place beforeoperating this equipment.

During operation, ensure that all personnel are a safe distance away from thisequipment.

Wear appropriate safety gear when installing, operating, or servicing this equipment.

Before doing any work on this equipment, make sure that all parts of the equipmenthave come to a complete stop. Lock out and tag out all sources of electrical power,pneumatic pressure, hydraulic pressure, and any other energy sources that couldcause any portion of the equipment to move.






1.5 WELDING PRECAUTIONS

Follow these additional precautions when welding on or near the drawworks:

Contact PREP before performing any welding on the drawworks. Welding may void thewarranty.

Follow approved welding procedure and safety practices when carrying out any weldingon the machinery.

Ensure the ground cable is clamped directly to the component to be welded and asclose to the weld as possible. Improper grounding can damage components that areaverse to electrical currents such as bearings, valves, and electrical components. Ifpossible, remove any current-averse components before welding.
