4.5 Inch Metal Cutting Bandsaw Assembly & Operating Instructions 8
OPERATION
BEFORE OPERATING YOUR BANDSAW please read manual carefully
.
BLADE GUIDE BEARING ADJUSTMENT
This is the most important adjustment on your saw. It is impossible to get satisfactory work from
your saw if the blade guides are not properly adjusted. The blade guide bearings for your Metal
Cutting Bandsaw are adjusted and power tested with several test cuts before leaving the
factory to ensure proper setting. The need for adjustment should rarely occur when the saw is
used properly. If the guides do get out of adjustment, it is extremely important to readjust
immediately. If proper adjustment is not maintained, the blade will not cut straight and if the
situation is not corrected, it will cause blade damage.
Because guide adjustment is a critical factor in the performance of your saw, it is always best to
try a new blade to see if this will correct poor cutting before beginning to adjust the bearings. If
a blade becomes dull on one side sooner than the other, for example, it will begin cutting
crooked. A simple blade change should correct this problem-the more difficult guide adjustment
will not.
If a new blade does not correct the problem, check the blade guides for proper spacing. There
should be 0.001" clearance between the 0.025" thickness blade and guide bearings.
To obtain this clearance adjust as follows:
1. The inner guide bearing is fixed and cannot be adjusted.
2. The outer guide bearing is mounted to an eccentric bolt and can be adjusted.
3. Loosen the nut while holding bolt
with a wrench.
4. Position the eccentric by turning the bolt to the desired position of clearance.
5. Tighten the nut.
6. Adjust the second blade guide bearing in the same manner.
7. The back edge of the blade should just touch the lip of the Blade Guide Bearing.
BLADE GUIDE ASSEMBLY ADJUSTMENT
The Metal Cutting Bandsaw is equipped with two adjustable blade guide assemblies. This
feature will permit you to adjust the position of the blade guides for various widths of
workpieces. For the most accurate cut and prolong the life of the blade, the blade guide
assemblies should be adjusted to just clear the piece to be cut.
1. Place the workpiece in the vice of bandsaw and clamp tightly.
2. Adjust catch blade guide assembly to the desired position by loosening the hand knobs and
positioning the guides as required.
3. Tighten the hand knobs.
ADJUSTING BLADE TENSION
1. Make sure the motor is switched off and the machine is disconnected from electricity supply.
2. Press the blade lightly with the left hand so that the rear of the blade touches the flange of
the blade wheel and adjust the blade tension adjusting knob with the right hand until no blade
slipping occurs.
