A Few Words About Safety

Safety Information

Read and understand the entire manual before

operating or maintaining Stoelting equipment.

This manual provides the operator with information

for the safe operation and maintenance of Stoelting

equipment. As with any machine, there are hazards

associated with their operation. For this reason safety

is emphasized throughout the manual. To highlight

speciﬁc safety information, the following safety deﬁni-

tions are provided to assist the reader.

The purpose of safety symbols is to attract your at-

tention to possible dangers. The safety symbols, and

their explanations, deserve your careful attention

and understanding. The safety warnings do not by

themselves eliminate any danger. The instructions

or warnings they give are not substitutes for proper

accident prevention measures.

If you need to replace a part, use genuine Stoelting

parts with the correct part number or an equivalent

part. We strongly recommend that you do not use

replacement parts of inferior quality.

WARNING

The signal word “WARNING” indicates a potentially

hazardous situation, which, if not avoided, may result

in death or serious injury and equipment/property

damage.

CAUTION

The signal word “CAUTION” not preceded by the

safety alert symbol indicates a potentially hazardous

situation, which, if not avoided, may result in equip-

ment/property damage.

NOTE (or NOTICE)

The signal word “NOTICE” indicates information or

procedures that relate directly or indirectly to the

safety of personnel or equipment/property.
