
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 Load Chain Lubrication
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 Hooks and Suspension Components
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.
6.3.2 Suspension Pins - Lubricate at least twice per year for normal usage; more frequently for heavier usage
or severe conditions.
