11.0 Adjustments

With the exception of blade

tracking, disconnect machine from the power source before making adj ustments or c hangi ng vise position. Failure to comply may cause serious injury.

11.1 Adjusting vise square to blade

(Position A, Figure 5)

1. Place a machinist's square on the bed against the blade and the vise. The square should lie along the entire length of the vise and blade without a gap.

2. If adjustment is necessary, loosen bolts (A, Figure 5) holding the vise and adjust vise so square lines up properly. Tighten bolts.

3. You may want to perform a test cut. Cut off the end of the stock. Make another cut so that you have an accurate section to measure. Measure thickness with calipers.

Figure 5

11.2 Adjusting vise for miter cuts

Figure 6

11.5 Semi-automat ic arm

Preset the height, which the arm stops when it raises automatically. The height the arm raises depends upon the piece you want to cut. The limit switch is lowered or raised by loosening a locking handle (A, Figure 7). Tighten the locking handle when the limit switch has been properly adjusted.

(Position B, Figure 5)

1. Move the vise into the second set of threaded holes (B, Figure 5) by removing hex cap bolts (A, Figure 5).

2. When angle has been set tighten bolts.

3. Adjust other jaw.

4. There is an angle label on the backside of the bed. This is for reference only. Check angles with a machinist’s protractor.

For your own safety: only use position B for miter cuts. Vise square to the blade, in position B would expose more of the blade, rig ht of the vise, t han is necessary for the cut.

11.3 Positioning vise

To position the moveable vise:

1. Pull up on the rack block (C, Figure 5).

2. Move vi se to desired location by sliding along bed.

3. Tighten vise by turning hand wheel, found at the left end of the bed, clockwise.

4. Loosen vise by turning hand wheel counterclockwise so you can pull up on the rack block.

Figure 7

11.6 Automatic shut-off

The blade will stop after the material has been cut, and the arm reaches its lowest position. The arm will automatically rise to the preset height.

11.4 Changing blade speeds

Adjust the variable blade speed only while the machine is running. The dial (A, Figure 6) sticking out of the belt cover (right side) controls the variable speeds between 66 FPM to 264 FPM.

11.7 Adjusting feed rate

Rate of downfeed is adjusted by turning the downfeed knob on the control panel. Rate of feed is important to band saw performance; excessive pressure may break the blade or stall the saw. Ins ufficient pressure rapidly dulls the blade.
