Load Chain
Do not allow chain to run dry.
Lubricant greatly increases life of load chain. Weekly lubrication and cleaning is satisfactory, but under hot, dirty, and ex-
treme conditions it may be necessary to clean chain at least once a day and lubricate it several times between cleaning.
Apply sufficient lubricant to obtain natural runoff and full coverage, especially in interlink area.
Apply Lubriplate® Bar and Chain Oil 10-R or equal lubricant. Machine or gear oil (grade ISO VG 46 or 68 oil or equivalent)
may be used as an alternative lubricant but must be applied more frequently.
