dling operation or performing any maintenance on semitrailer. Maintain

nance is completed. DO NOT connect semitrailer grounding cable (4) to

painted surfaces. An unbonded and ungrounded or improperly bonded and
grounded semitrailer could produce a spark. The resulting explosion will
cause serious injury or death to personnel.
