LUERICATIQf^:
Motor bearings are sealed and do not require lubrication service.
Tumbler and idler bearings equipped with grease fittings should be lubricated
twice annually with a general purpose lithium base grease. Do not over grease.
Rotate shaft and add grease slowly until it begins to show at the seals'. Do
not use animal or vegetable base lubricants.
GAS CONNECTIONS:
Non-permanent gas connections (unions, flared tube fittings,
pilot line connections, gas manifold orifices, etc.) should be checked two or
three times annually for leakage that might be caused by vibration. Use a mild
soap solution. Do not use a flame at any time to check for leaks.
EŒCTRICAL CONNECTIONS:
Electric service and grounding connections should be
examined for looseness a week after initial installation, again after 3 or 4
weeks of operation, and thereafter two or three times annually.
