FORWARD
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.
