ALWAYS MAKE DRY RUNS TO CHECK FOR CLEARANCE AND CORRECTNESS OF CUTS.

SPECIAL CUTS

NEVER MAKE ANY CUT WITHOUT FIRMLY CLAMPING THE MATERIAL.

Aluminum Cutting:

Aluminum extrusions such as those used when making aluminum screens and storm windows can easily be cut with your saw. Position the material so that you will be cutting the thinnest cross section, as shown in Figure 26. Figure 27 illustrates the wrong way to cut these extrusions.

Use a wax lubricant when cutting aluminum such as Johnson’s Stick Wax No. 140. Apply the stick wax directly to the saw blade before cutting. Never apply stick wax to a moving blade.

The wax, available at most hardware stores and industrial mill supply houses, provides proper lubri- cation and keeps chips from adhering to the blade.

Bowed Material:

When cutting bowed material always position it as shown in Figure 28 and never like that shown in Figure 29. Positioning the material incorrectly will cause it to pinch the blade near the completion of the cut.

Cutting Plastic Pipe

Plastic pipe can be easily cut with your saw. It should be cut just like wood and CLAMPED OR HELD

FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING.

Cutting Large Material

Occasionally you will encounter a piece of wood a little too large to fit beneath the blade guard. A little extra height can be gained by rolling the guard up out of the way, as shown in Figure 23. Avoid doing this as much as possible, but if need be, the saw will operate properly and make the bigger cut.

NEVER TIE, TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THIS SAW.

Troubleshooting Tips

If your saw makes unsatifactory cuts:

Replace dull blades

Check to see if blade is mounted backwards.

Remove blade and clean with turpentine and coarse steel wool or household oven cleaner. Check to make sure the blade you are using is appropriate for work being done.

If blade does not come up to speed:

Extension cord may be too light or too long.

You may have low house current.

If your machine vibrates excessively:

Saw may not be mounted securely to stand on work bench.

Stand may be on uneven floor.

Blade may be damaged.
