ASSEMBLY

SQUARING THE SAW TABLE TO THE BLADE

See Figure 8.

Turn the lock knob counterclockwise to unlock the blade guide assembly. Turning the blade guide knob clockwise, raise the blade guide assembly as far as it will go. Turn the lock knob clockwise to retighten.

Place a small combination square on the saw table beside the blade.

Loosen the table lock knob and rotate the angle adjustment knob to tilt the saw table up or down to align table 90° to blade (0° position). Retighten the table lock knob.

Using a 4 mm hex key, adjust the zero stop set screw until the set screw just touches the saw housing.

Check squareness of the saw table to the blade. Make readjustments if necessary.

Loosen screw on scale indicator with a phillips screwdriver and align scale indicator to zero.

Tighten all screws securely.

ADJUSTING BLADE TENSION

See Figures 9 and 10.

Remove the switch key.

Before using the band saw, turn the blade tension knob on the top of the saw clockwise to engage tension.

NOTE: Adjustments of blade tension can be made at anytime.

Another method of checking blade tension has to do with the sound the blade makes when plucked like a guitar string.

Pluck the back straight edge on the coasting side opposite the blade guides while turning the tension knob. Sound should be a musical note. Sound becomes higher pitched as tension increases.

Using either method to check blade tension can be devel- oped with practice.

Never increase blade tension so tight as to completely compress the spring. When completely compressed, the spring can no longer act as a shock absorber.

NOTE: Too much tension may cause the blade to break. Too little tension may cause the blade to slip on the wheels.
