MAINTENANCE

To Check Miter Fence Alignment

See Figure 53.

The miter fence must be perpendicular to the blade when set at zero degrees.

WARNING:

Begin by unplugging your saw. Failure to unplug saw could result in accidental starting causing possible serious injury.

Set the miter fence (H) at 0° as shown in figure 53. Miter indicator (I) should be set precisely on 0° and secured in place with adjusting clamp (J).

Note: The quick-stop is not necessary for this checking

procedure. However, you may want to check and adjust it to 0° at this time. See Quick-Stopsection that follows.

Place a framing square (G) firmly against the miter fence

(H) with the other side against the blade (E).

Check whether the miter fence and blade are square with each other. With the framing square against the miter fence there should be no gap from the front to the rear of the blade.

If a gap exists, the miter fence may be out of square.

Rotate the blade and recheck. If there is a consistent gap between the front and rear of the blade, the miter table needs aligning. Follow the adjustment procedures that follow.

MAKING ADJUSTMENTS TO SLIDING MITER TABLE ASSEMBLY

To Adjust the Miter Base

See Figure 54.

REMEMBER: Check all settings before loosening screws for the following procedures. Once screws have been loosened, these settings must be reset.

Eight screws are visible on the miter base (B).

Four screws (K) are on the holder plates and secure these plates to the rails. It is not necessary to loosen or adjust these screws for this adjustment procedure.

Another pair of screws (L) is in the base, at the rear. Loosen these two screws (L) and the rear miter locking clamps (M).

The last pair of screws is located on the infeed side of the base. Loosen the left screw (N) only.

The right screw (O) will be used as a pivot point.

Note: The front two miter locking clamps (P) and rail clamps should remain locked.

Follow the steps in TO CHECK MITER BASE PARALLELISM, adjust the miter base so that it is parallel to the blade.

Retighten the left front screw (N).

Clamp the rear miter locking clamps (M).

Retighten the two rear screws (L).
