FOREWARD
This manual contains important information to help you properly install, operate and maintain your hoist for maximum performance, economy
and safety.
Please study its contents thoroughly before putting your hoist into operation. By practicing correct operating procedures and by carrying out
the recommended preventive maintenance suggestions, you will experience long, dependable and safe service. After you have completely
familiarized yourself with the contents of this manual, we recommend that you carefully file it for future reference. The information herein is
directed to the proper use, care and maintenance of the hoist and does not comprise a handbook on the broad subject of rigging.
Rigging can be defined as the process of lifting and moving heavy loads using hoists and other mechanical equipment. Skill acquired through
specialized experience and study is essential to safe rigging operations. For rigging information, we recommend consulting a standard
textbook on the subject.
