Grizzly’s G1127 Extension Block increases the cutting height of the Model
G1019 Bandsaw by six inches. With the extension block installed, the saw is
capable of cutting stock up to 12" in height.
For best results while installing the Extension Block, we recommend referring
to the parts diagram on the last page of this instruction sheet. The numbers on
the diagram refer to the components supplied in the Extension Block Kit. The
letters refer to parts of your existing bandsaw setup. There are references to
the manual that was supplied with your saw, so have it close at hand.
1. Disconnect the bandsaw from electrical power before
beginning.
2. Remove the blade per the manual instructions.
3. Remove the blade guide assembly by loosening the
Lock Knob Ref C and sliding the Guide Post Ref D out

Seek assistance before continuing with this next
step. Remove Upper Frame Arm Ref A from the Base
Ref B by removing the Hex Bolt Ref D and Hex Nut

base. It will be necessary to rock the Upper Frame Arm
gently back and forth to work it loose of the base. Take
care in lifting it off the base and setting it to one side.
5. Remove the two Set Pins Ref G which are in the top
of the Base by using a pair of pliers and twisting it until
they come free. These will not be reused.

line up the mounting hole to the base mounting hole.
The Upper Frame Arm represents a heavy load.

the Extension Block to the Base. Do not tighten at this
time.
