Porter-Cable 28-248 Tracking the Blade, Vertical Adjustment of the Upper Blade Guide Assembly

Page 20

5.The band saw blade tension can be fined tune by turning adjustment nut (N) Fig. 51, while the blade is tensioned.

6.A series of graduations is located on the back of the upper wheel slide bracket (T) Fig. 51. These graduations indicate the proper tension for various widths of blades.

NOTE: THESE GRADUATIONS ARE CORRECT FOR AVERAGE WORK, AND WILL NOT BE AFFECTED BY REBRAZING OF THE SAW BLADE.

WHEN CUTTING THIN PIECES, 3/4" OR LESS, SET THE BLADE TENSION BELOW THE MAXIMUM SETTING FOR BLADE WIDTH, TO EXTEND BLADE LIFE.

OVER-STRAINING IS A COMMON CAUSE OF BLADE BREAKAGE AND OTHER UNSATISFACTORY BLADE PERFORMANCE. RELEASE THE TENSION WHEN THE TOOL IS NOT IN USE.

TRACKING THE BLADE

DISCONNECT MACHINE FROM POWER SOURCE.

BEFORE TRACKING THE BLADE, MAKE SURE THAT THE BLADE GUIDES AND BLADE SUPPORT BEARINGS ARE CLEAR OF THE BLADE.

After applying tension to the blade, rotate the wheels slowly forward by hand and observe the blade’s movement. The blade (A) Fig. 52 should travel in the center of the upper tire. If the blade creeps toward the front edge, loosen the wing nut (B) Fig. 51, and turn the thumb screw (C) clockwise. This action draws the blade toward the center of the tire. If the blade creeps toward the back edge, turn the thumb screw in the opposite direction. Adjust the thumb screw (C) Fig. 51 only a fraction of a turn each time.

NEVER TRACK THE BLADE WHILE

THE TOOL IS RUNNING.

After the blade is tracking in the center of the tires, tighten the wing nut (B) Fig. 51.

VERTICAL ADJUSTMENT OF THE UPPER BLADE GUIDE ASSEMBLY

DISCONNECT MACHINE FROM POWER SOURCE.

Adjust the blade guides and bearings according to the following instructions.

Set the upper blade guide assembly (A) Fig. 53 as close as possible to the top surface of the workpiece. Loosen the lock knob (B) and move the guide assembly (A) to the desired position.

The 28-475X features a stainless steel magazine that ensures durability and smooth operation while reducing the risk of jams.

This model also includes a selective actuation switch, allowing users to choose between sequential and contact firing modes based on their needs. The built-in dry fire lockout mechanism is another valuable feature that prevents the tool from firing without nails, which prolongs its lifespan and ensures safety.

The ergonomic design of both models emphasizes user comfort, with features like rubber grips that minimize fatigue during prolonged use. Both tools are compatible with a variety of nail sizes and types, making them suitable for a range of tasks from cabinetry to flooring installations.
