CAUTION STATEME NT
To retain permissibility of this equipment the following conditions shall be satisfied:
1.General Safety. Frequent inspection shall be made. All electrical parts, including the portable cable
and wiring, shall be kept in a safe condition. Special efforts shall be made to maintain cable routing paths
free from mud rock and other debris that could eventually cause cable damage. Cables should be closely
examined on a regular basis and damaged cables or protective hose conduits shall be replaced and the
cause of the damage identified and corrected before the equipment is placed back into service. There
shall be no openings into the casings of the electrical parts. A permissible distribution box shall be used
for connection to the power circuit unless connection is made in fresh intake air. To maintain the overload
protection of direct-current machines, the underground conductor of the portable cable shall be connected
to the proper terminal. The machine frame shall be effectively grounded. The power wires shall not be
used for grounding except in conjunction with diode(s) or equivalent. The operating voltage should match
the voltage rating of the motor(s).
2.Servicing. Explosion-proof enclosures shall be restored to the state of original safety with respect to all
flame arresting paths, lead entrances, etc. following disassembly for repair or rebuilding, whether by the
owner or an independent shop.
3.Fastenings. All bolts, nuts, screws and other means of fastening, and also threaded covers, shall be in
place, properly tightened and secured.
4.Renewals and Repairs. Inspections, repairs or renewals of electrical parts shall not be made unless the
portable cable is disconnected from the circuit furnishing power, and the cable shall not be connected
again until all parts are properly reassembled. Special care shall be taken in making renewals or repairs.
Leave no parts off. Use replacement parts exactly like those furnished by the manufacturer. When any
lead entrance is disturbed, the original leads or exact duplicates thereof shall be used and stuffing boxes
shall be repacked in the approved manner. When machine cables are replaced or otherwise disturbed
from their normal position, they shall be routed in the same manner as they were when the machine was
shipped from the manufacturer. In addition, any clamps, conduit or guards, that were in place to prevent
cable damage shall be replaced.
5.Cable Requirements . A flame resistant portable cable bearing a MSHA assigned identification number,
adequately protected by an automatic circuit-interrupting device shall be used. Special care shall be
taken in handling the cable to guard against mechanical injury and wear. Splices in portable cables shall
be made in a workmanlike manner, mechanically strong, and well insulated. One temporary splice may
be made in any trailing cable. Such trailing cable may only be used for the next 24-hour period. No
temporary splice shall be made in a trailing cable within 25 feet of the machine, except cable reel
equipment. Connections and wiring to the outby end of the cable shall be in ac cor danc e wit h recog ni zed
standards of safety.
DO NOT CHANGE WITHOUT APPROVAL OF MSHA
