G4186Z 18" Bandsaw

G. These knobs control blade tracking. Note

that the knobs have lock nuts to lock the

tracking in place.

H. The upper guide can be easily adjusted

using this handwheel. Adjust it to within

⁄4" of

the workpiece for optimum blade support.

I. This knob locks the upper blade guide

assembly in position. Do not operate the

bandsaw without locking the guide post

knob.

J. This hub controls the lower wheel move-

ment. Each bolt on the hub moves that por-

tion of the wheel in or out. For example, the

top bolt controls the top of the wheel, the left

bolt controls the left of the wheel and so

forth.

Blade Tension

Proper blade tensioning is important for optimum

bandsaw performance. See Figure 11 for the

location of the bandsaw tension controls.

Since a wide range of blades will work well in this

saw, proper blade tension ultimately depends on

the type and the size of blade you use. Thinner

blades require less tension than wide blades. Too

much tension will result in blade breakage. A

properly tensioned blade will track the cutting line

accurately and the cut will be smoother.

Proper blade tension can best be achieved by

determining the amount of blade deflection:

1. Ensure that the power is off and the saw is

unplugged. Raise the upper guide assem-

bly all the way.

2. Press, with moderate pressure, on the face

of the blade with your thumb. The blade

should flex about

3. Turn the tensioning knob at the top of the

machine to change the amount of tension.

If the tension seems correct, make the other

adjustments to the saw (making wheels coplanar,

aligning guides, tracking, speed, table and fence)

and test run the bandsaw. If the blade is not cut-

ting properly, the tension may be incorrect and

you will need to re-adjust the tension. Remember

to reduce the blade tension when the saw will not

be in use; this will help to prevent premature wear

or breakage of the blade and/or rubber tires.

The bandsaw blade is dangerously sharp.

Use extreme caution when working near the

saw blade. Failure to exercise care could

result in severe injury.
