  • Page 17: G3619/G3620 Tracking

    G3619/G3620 Tracking The wheels on the Model G3619/G3620 Resaw Bandsaws are crowned with rubber tires. This style requires center tracking for proper opera- tion. To center track your blade: Make sure the bandsaw is unplugged! Open the upper wheel cover door. Slowly rotate the upper wheel and watch where the blade rides on the wheel.

  • Page 18: Support Bearings

    Adjust the tracking handwheel until the blade gullets ride approximately edge of the wheels while you are spinning the upper wheel by hand. Your saw is now properly tracked. Support Bearings The support bearings back-up the blade during the sawing operation.

  • Page 19: Guide Blocks

    Guide Blocks The guide blocks ensure that the blade cannot move side-to-side too far during operation. Perform steps 1-4 for both upper and lower guide blocks. Loosen the guide blocks from the center setscrew in the guide bracket. The guide blocks should be approximately .004"...

  • Page 20: Table Stop

    Blade Guard The blade guard is attached to the guide post above the upper blade guide assembly. For prop- er setup, the blade should be centered in the blade guard. To center the blade guard: Loosen the hex bolt that secures the blade guard bracket to the guide post.

  • Page 21: Table Tilt

    Loosen the large hex bolt and the jamnut in the center of the table trunnion. Raise the upper blade guide assembly and place a 6" machinist’s square on the table against the blade as shown in Figure 16. Notice how far out of square your table is and approximate this distance by adjusting the positive stop up or down.

  • Page 22: Test Run

    The rest of the adjustments in this section require you to start the bandsaw. Before starting the bandsaw, make sure you have performed the preceding assembly and adjustment instructions, and you have read through the rest of the manual and are familiar with the various functions and safe- ty issues associated with this machine.

  • Page 23: Fence Adjustment

    To adjust the fence so it is parallel with the blade: With a different saw, cut a board to 1" x 4" x 28". Down the length of the board, joint one edge perfectly straight, or rip a narrow strip off the length of the board with a table saw.

    Blade Length Measured by the circumference, blade lengths are usually unique to the model of your bandsaw and the wheel diameter. The Model G3619/3620 is designed for blades that are 175" long. The Model G9963/G9966 requires blades that are Blade Width...
  • Page 25 This extra resistance will also cause unnecessary heat. Maintain your blades with a cutting blade lubricant like SLIPIT G5562/3 in the Grizzly Catalog). Blade Breakage Many conditions may cause a bandsaw blade to break. Blade breakage is unavoidable, in some cases, since it is the natural result of the peculiar stresses that bandsaw blades are subjected to.

  • Page 26: Blade Changes

    Blade Changes Always power to the machine when changing blades. Failure to do this may result in serious person- al injury. To remove the blade: After making sure unplugged, release the tension on the blade by turning the tension control knob counter- clockwise.

  • Page 27: Ripping

    See Figure 19. The maximum board width that can be ripped is limit- ed by the maximum throat dimension of the band- saw. For ripping, a wider blade is better. In most rip- ping applications, a standard raker tooth style will be sufficient.

  • Page 28: Resawing

    Use the widest blade that will fit your band- saw. (Use the data sheets in the back of this manual to determine the maximum blade width for your saw.) The blade must also be sharp and in good condition.
