6.0 Lubrication 

6.1.1 

See Section 3.0 for lubrication requirements. 

6.1.2 

 Lubrication to the motor will be provided primarily by the air supply lubricator.  The 

recommended amount is 10-15 drops/minute (2-3cc/min.).  Refer to 

Table 6-1

 below for the approved 

lubricant for use with your air hoist. 

6.1.3 

Additional lubrication to the reduction gears is not necessary.  When disassembling the hoist for service 
or repair, apply new grease to the gears before reassembling the hoist.   

6.2.1 

For longer life, lightly coat the load chain with machine or gear oil.  Ensure that the oil is applied to the 
bearing surfaces of the load chain links.   

6.2.2 

The load chain lubrication should be accomplished after cleaning the load chain with acid free cleaning 
solution.  Use approved lubricant in 

Table 6-1

 or equivalent.   

6.2.3 

For dusty environments, it is acceptable to substitute a dry lubricant.   

6.3.1 

Hooks - Bearings should be cleaned and lubricated at least once per year for normal usage.  Clean and 
lubricate more frequently for heavier usage or severe conditions.

or severe conditions.
