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.

hazardous situation, which, if not avoided, may result
in death or serious injury and equipment/property
damage.

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)

procedures that relate directly or indirectly to the
safety of personnel or equipment/property.
