Porter-Cable 3700L Typical Operations and Helpful Hints, Adjusting Lower Blade Guard

Page 16

TO SET LEFT and RIGHT KERF ADJUSTMENT

1.Use the 1/8" hex wrench to turn the left or right kerf adjustment screws and set the laser lines to either side of the test cut (Fig. G). To adjust the left line, turn the left kerf adjustment screw counter-clockwise to move the line toward the blade and clockwise to move the line away from the blade. To adjust the right line turn the right kerf adjustment screw counter-clockwise to move the line toward the blade and clockwise to move the line away from the blade. (Fig. H)

Observe the laser CAUTION label (L)

Fig. H.

2. Remove the padlock and use the saw normally.

TwinLaser™ MAINTENANCE

For best laser performance, perform the following maintenance regularly:

DISCONNECT THE MACHINE FROM

THE POWER SOURCE.

1.Carefully clean sawdust from each laser lens (A) Fig. J with a cotton swab (B). Do not use solvents of any kind since they may damage the lens. Avoid touching sharp points of the saw blade with your hands or fingers. Dust build-up can block the laser and prevent it from accurately indicating the line-of-cut.

2.Remove the blade from the saw and clean pitch build-up from the blade (Fig. K) Pitch build-up can block the laser and prevent it from accurately indicating the line-of-cut.

ADJUSTING LOWER BLADE GUARD

After an extended period of use, the movable lower blade guard

(A)Fig. 32 may not operate smoothly when the cuttinghead is lowered. You can correct this by adjusting the nut (B) until the lower blade guard (A) moves freely.

Do not over-tighten the nut as this can make the guard hard to move.

MACHINE USE

TYPICAL OPERATIONS AND HELPFUL HINTS

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

2.Place the workpiece on the table and hold or clamp it firmly against the fence. Fig. 33 illustrates the work clamp (A). The clamp (A) can also be used on the right side of the machine.

3. If the position or size of the workpiece causes your hand to be in the “Hazard Zone”, use the work clamp to secure the workpiece. Keep your hands out of the “Hazard Zone”.

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

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