7.5.1 

Whenever the hoist is to be placed into storage, place extra lubricating oil into the air inlet opening and 
circulate the air motor before plugging the inlet.  Make certain that no debris, dirt or moisture is allowed 
to enter the air hoist through air inlet opening during preparations for storage. 

7.5.2 

The storage location should be clean and dry.   

7.6.1 

For hoist installations that are outdoors, the hoist should be covered when not in use.  

7.6.2 

In order to prevent internal corrosion from occurring, the hoist must be operated using proper quality air 
at least once per week by raising and lowering the hoist one full cycle.  Note: the possibility of corrosion 
in the valve section of the hoist increases for areas where salt air and high humidity are present.  For 
such situations you may need to operate your hoist more often than once per week.
