SERVICE & MAINTENANCE
Blade Guide Bearing Adjustment
Proper adjustment of the blade guide bearings is critical to efficient operation of the bandsaw. The blade guide bearings are adjusted at the
factory. They should rarely require adjustment. When adjustment is required, readjust immediately. Failure to maintain proper blade adjustment
may cause serious blade damage or inaccurate cuts.
It is always better to try a new blade when cutting performance is poor. If performance remains poor after changing the blade, make the
necessary adjustments.
If a new blade does not correct the problem, check the blade guides for proper spacing. For most efficient operation and maximum accuracy,
provide 0.001” clearance between the blade and the guide bearings. The bearings will still turn freely with this clearance. If the clearance is
incorrect, the blade may track off the drive wheel.
Warning! Disconnect the bandsaw from its electrical power source.
Caution!
Check the blade to make sure the welded section is the same thickness as the
rest of the blade. If the blade is thicker at the weld, the guide bearings may be damaged.
If required, adjust the guide bearings as follows:
1) The upper and lower blade guides are adjusted the same way.
2) Loosen the 2 blade guide set screws (A-Fig.10) with a hex. key.
3) Position the bearing by turning the eccentric shaft (B-Fig.10). Set the clearance by
approximately 0.001”.
4) Retighten the blade guide set screws with the hex. key.
5) Use the same procedure to adjust the other blade guide bearing.
6) When the adjustment is correct, the guide bearings should rotate freely with slight
pressure of the finger (blade stopped).
Cleaning
1. Clean off any oil and grease on the machine surfaces.
2. After cleaning, coat the machined surfaces of the bandsaw with a medium consistency machine oil. Reapply the oil coating at least every six
months.
3. Clean up accumulated saw cuttings after use.
Lubrication
Lubricate the following components at the recommended intervals using the lubricants specified:
1. Upper wheel bushing: six to eight drops of oil each week.
2. Pivot points, shafts and bearing areas: six to eight drops of oil each week.
3. Ball bearings: the bearings are lubricated and sealed, periodic lubrication is not required.
4. Blade guide bearing: the bearings are lubricated and sealed, periodic lubrication is not required.
Changing the Drive Motor V-Belt
Warning! Disconnect the band saw from its electrical power source.
1. Move the bandsaw frame in the rearmost position by pushing down on the saw frame release lever (H-Fig.6) and lock it by turning the
hydraulic
feed stop dial
(E-Fig.6) clockwise.
2. Remove the cabinet side panel to expose the belt and pulleys.
3. Pivot the motor upwards to loosen the belt.
4. Remove the worn belt.
5. Put the replacement belt in the pulley position for the speed you require.
6. Tighten the belt by lowering the motor downward.
7. Replace the cabinet side panel and unlock the bandsaw frame.
