The door chains and sprockets have been lubricated at the factory with high temperature "Never Seeze"
lubricant. After each six months of usage, lubricate the door chains and sprockets with the same type of
lubricant.
Motor lubrication information can be found on permanent label located on motor.
Casters are provided with a Zerk fitting for proper lubrication when required.
