NOTE:

Some types of plastics lend themselves to more pronounced results with the regular saw blades.

 

Sheets under ¼” thickness and tubing under ¼” wall thickness are not adapted to skip tooth blades.

MAINTENANCE

CHANGING THE BLADES

DISCONNECT MACHINE FROM POWER SOURCE.

1.Open the upper and lower wheel guard doors and blade guard door.

2.Release tension on the saw blade.

3.Remove table alignment pin and table insert.

4.Take the blade off the wheel, and guide it through the slot in the table.

5.Install the new blade by reversing the procedure. Table alignment pin should be re-seated by gently tapping it with a hammer.

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.
