Delta 36-312 Adjusting Lower Blade Guard, Typical Operations and Helpful Hints, Cutting Aluminum

ADJUSTING LOWER BLADE GUARD

This machine incorporates a blade guard (A) Fig. 32A to cover the rear section of the blade. After an extended period of use, the movable lower blade guard may not operate smoothly when the cuttinghead is lowered. This can be corrected by adjusting nut (B) until the lower blade guard moves freely.

Overtightening the nut could impair guard movement.

NOTE: This unit has been designed with an articulating rear guard. Before contacting the workpiece, the rear guard will rotate upward to expose more of the blade as the cuttinghead is lowered.

Do not remove any of the blade guards. Make sure that all guards are in place and functioning properly before operating the saw.

Make sure that the fences are clear of the guard and blade before operating the saw.

TYPICAL OPERATIONS AND HELPFUL HINTS

If the size of the workpiece causes your hand to be inside the table hazard zone (see section “TABLE HAZARD ZONE” SEE FIG. 21), use a clamp to secure the workpiece.

1.Before cutting, make certain that the cutting arm and table area are at their correct settings and firmly locked in place.

2.Before cutting, determine that the workpiece is the right size for the saw.

3.Place the workpiece on the table and hold or clamp it firmly against the fence.

4.For best results, cut at a slow, even cutting rate.

5.Never attempt freehand cutting (cutting a workpiece that is not held firmly against the fence and table).

AUXILIARY WOOD FENCE

When performing multiple or repetitive cut-off operations that result in small cut-off pieces (one inch or less), the saw blade can catch the cut-off pieces and project them out of the machine or

into the blade guard and housing, possibly causing damage and/or injury. In order to limit the possibility of personal injury or blade guard damage, mount an auxiliary wood fence to your saw.

Holes are provided in the fence to attach an auxiliary fence (A) and (B) (Fig. 32B). This auxiliary fence is constructed of straight wood approximately 1/2” thick. Side A should be approximately 5.25" high by 10.5" long and side B should be approximately 3" high by 10.5" long.

NOTE: The auxiliary fence (A) is used only with the saw blade in the 0° bevel position (90°) to the table. The auxiliary fence must be removed for all bevel cuts (blade tilted).

Make sure that the fence is clear of the guard and blade before operating the saw.

CUTTING ALUMINUM

To reduce the risk of injury, use the proper blade when cutting this type of material.

Aluminum extrusions (aluminum screens and storm windows) can easily be cut with your miter saw. When cutting aluminum extrusions, or other sections that can be cut with a saw blade and are within the capacity of the machine, position the material so that the blade is cutting through the smallest cross-section, as shown in Fig. 34 The wrong way to cut aluminum angles is illustrated in Fig. 35. Be sure to apply a stick wax (similar to Johnson’s stick wax #140) to the blade before cutting any aluminum stock. This stick wax is available at most industrial mill supply houses. The stick wax provides proper lubrication and keeps chips from adhering to the blade.

Never apply lubricant to the blade while the saw is running.
