12. MASTS E-MS SERIES LIMITED FREE LIFT 2-STAGE MAST

Each pair of chains has been factory-lubricated using heat and pressure to force the lubricant thoroughly into the chain links. Avoid removal or contamination of this factory applied lubricant. Do not wash, sand blast, etch, steam clean, or paint the chains on initial mast installation.

The chains must be adjusted with equal tension to ensure proper load distribution and mast operation. To determine equal tension, extend the unloaded mast to put the chains under tension. Press the center of a strand of chain with your thumb, then press at the same place on the other chain of the pair. Each chain in a pair should have equal

“give”. If tension is not equal, adjust the chains as de- scribed in Chain Adjustment.

Inspect the chains. If inspection reveals that one strand of a pair of chains requires replacement, both strands of the pair should be replaced.

*Check for cracked side plates. If you find cracked side plates, replace both strands of chain.

*Check for tight joints. If tight joints are caused by rust or corrosion, loosen them with SAE 40 wt. oil or penetrating oil. If they cannot be loosened, or if the tight joints are caused by bent pins or plates or by peened plate edge, replace both strands of the chain.
