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

NEVER MAKE ANY CUT WITHOUT FIRMLY CLAMPING THE MATERIAL.
A A l l u u m m i i n n u u m m C C u u t t t t i i n n g g : :
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.
B B o o w w e e d d M M a a t t e e r r i i a a l l : :
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.

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.
