BOOM CHAIN LUBRICATION
Lubricate inner chains and chain sheaves through windows with boom fully extended and set
horizontally. There are grease fittings on chain sheave shafts both inside and outside the
boom. Reach in through boom windows with a long tipped oil can and spray chains generously
and grease sheave fittings. Do not attempt to grease chain shafts or oil chains inside boom with
engine running, as boom may move while your hands are inside.
