MAINTENANCE
LUBRICATION
The gear case is filled at the factory with 1-1/2 quarts of
oil. The case should be drained after 1500 to 2000 hours
of operation and filled with a good grade of heavy
adhesive gear oil. A pipe plug is located below the
elbow (B) Fig. 62. Remove this plug to drain the oil.
This machine is equipped with a 1/2" street elbow (B)
Fig. 62 and a pipe plug (A).Remove the plug (A) to check
the oil level and, when necessary, to add oil. The oil level
should be approximately at the top of the bend in the
elbow (B).
The sealed-for-life ball bearings on the wheels of the
bandsaw and the blade supports require no lubrication.
