LUBRICATION
The gear case is filled at the factory with 11: quarts of
oil. It should be drained after 1500 to 2000 hours of
operation and refilled with a good grade of heavy
adhesive gear oil. A pipe plug is provided underneath
the band saw and is removed when draining the oil.
All models are equipped with a ,2-inch street elbow (A)
Fig. 24, and a pipe plug (B).
Remove the pipe plug (B) Fig. 24, to check the level of
oil in the gear case from time to time and keep it filled to
insure proper gear lubrication.
The wheels of the band saw are turned on permanently
sealed ball bearings, which require no lubrication. Ball
bearing blade supports are of the same type. Oil of
every kind should be kept away from the blade
supports.
