Proper operation of the Counterweight Removal System depends on a properly lubricated counterweight chain. If the chain is not lubricated properly, the chain may rust and seize during the removal operation. A seized chain can fracture and result in complete failure of the chain. The counterweight can then suddenly fall which can result in personal injury or death.Visually inspect the top of the counterweight chain for proper lubrication and rusting on a monthly basis. Lubricate the top of the chain, as required with 30 wt engine oil. Always lubricate the chain during removal of the counterweight, after the counterweight is lowered to the blocks on the ground. Use an approved ladder or platform when lubricating the upper portion of the chain.If seizure of the chain occurs during counterweight removal, stop the operation of the counterweight removal system and contact your nearest dealer for chain replacement.
The counterweight removal chain must be clean and free from rust. A chain with dirt or rust cannot be wound correctly.
Inspect the chain.
Remove any foreign material and rust from the chain.
