6.0 MAINTENANCE AND REPAIR
6.1 Cutting the Chain
The load chain is hardened and is difficult to cut. The following methods are recommended when cutting a length of new
chain from stock or cutting off worn chain.
Always wear eye protection when cutting the load chain.
Use a grinder and nick the link on both sides, then secure the link with a vise and break off the chain link with a
hammer.
Use a 7” minimum diameter by 1/8” thick abrasive wheel (or type recommended by your wheel supplier) that will
clear the adjacent links.
6.2 Lubrication
Load Chain: The full length of the chain must be lubricated, including where the chain passes over the chain
wheel(s). Ensure that the contact points between the links (i.e. the chain saddles) are adequately lubricated. A
small amount of lubrication will greatly increase the life of the load chain. DO NOT allow the chain to run dry.
Keep the chain clean and lubricate the chain at regular intervals with Lubriplate Bar and Chain Oil 10-R or equal
lubricant. Normally, weekly lubrication and cleaning is satisfactory, but under hot and dirty conditions, it may be
necessary to clean the chain at least once daily and lubricate the chain several times between cleanings. When
lubricating the chain, apply sufficient lubricant to obtain natural run-off and full coverage, especially in the
interlink area.
Cutting chain can produce flying particles. Wear eye protection. Place shield over chain to
prevent flying objects.
Used motor oils contain known carcinogenic materials. Never use used motor oils as a chain
lubricant. Only use Lubriplate Bar and Chain Oil 10-R or equal lubricant as a lubricant for the
load chain.
Use of commercial or other manufactures’ chain and parts to repair MH Hoists may cause load loss. Use
only factory supplied replacement load chain and parts. Chain and parts may look alike, but factory
original chain and parts are made of specific materials or processed to achieve specific properties.
A worn chain can be an indication of worn hoist components. For this reason, the hoist’s chain guide, hook
block and lift wheel should be examined for wear and replaced as necessary when replacing worn chain.
