Lubrication
Proper lubrication with machine oil is necessary to increase the life of the chain. Lubrication should be done
based on usage and on a regular basis. It may be necessary on a weekly basis for heavy use or monthly if
used less often.
• Clean the chain with an acid free cleaning solution to remove debris.
• Apply oil to chain focusing on bearing surfaces such as interlink areas.
• Do not apply oil to braking surfaces.
• Gears and shafts run on sealed bearings and do not require lubrication.

2. Remove the lock nut (35), screw (39), lock washer (38), hand wheel (27), lever handle (22), overload/
