MAINTENANCE

TO ADJUST THE FRONT AND REAR RAIL CLAMPS

See Figure 49.

The rail clamps are located below the rails and ensure tight attachment of the rail. Following extended use, the rail holder nut inside the rails may need adjusting.

Remove the miter table and accessory table.

Remove the front and rear rails by loosening the rail clamps and sliding the rails off.

Rotate each rail clamp to the left until it hits or comes in contact with the bottom of the saw table.

Tighten rail holder nut until it is snug.

Loosen rail holder nut one-fourth (1/4) turn.

Replace the rails and check the rail clamps.

TO ADJUST THE ACCESSORY TABLE

See Figure 50.

After extended use, the accessory table may work loose causing the accessory table to be loose on the rails. Follow the steps below, when adjustments are required:

Remove the hex nut on the lever using a 3/8 in. nut driver.

Remove the backup plate and spring plate. Rotate the spring plate 180° and reinstall on the handle shaft.

Reassemble all parts and tighten hex nut securely.

Note: The spring plate offers two ends for use before requiring replacement.

TO ADJUST THE SLIDING MITER TABLE ASSEMBLY

The sliding miter table assembly has been preset at the factory to be parallel to the blade. However, misalignment during shipping or requirements for very precise and accurate cuts may require realignment. The square relationship between the blade and the miter fence as it travels the entire distance from the front to the rear of the miter table base during a cut is very important for making precise and accurate cuts.

To avoid unnecessary setups and adjustments, we suggest that you check these setups carefully with a framing square and make practice cuts in scrap wood before making finish cuts in good workpieces.

Note: Follow the general rule of measuring twice and cutting once.

Do not loosen any screws for the following adjustments until you have made checks and are sure adjustments are needed. Once screws have been loosened, these settings must be reset.

Two basic checks should be made to determine if adjustments are necessary:

The miter base must be parallel to the blade as the table slides from the front to the rear of the miter table assembly.

The miter fence must be square to the blade when set at exactly zero (0° ) on the miter table scale. This is necessary in order to be able to use the scale on the miter table. The

miter table has adjustment screws for squaring miter fence to blade and maintaining 0° scale settings when miter base adjustments are required.

Note: These checks and adjustments are being explained in step by step procedures, however, you should be aware that they depend upon each other.
