Assembly
This machine comes pre-assembled from the fac-
tory. However, tension has been removed from
the blade for shipping purposes. Before operating
the machine for the first time, you MUST make
sure the blade is properly tensioned. Refer to the
Tensioning Blade procedure on this page for
instructions about how to do this.
Initial Lubrication
Your machine was lubricated at the factory, but we
strongly recommend that you inspect all lubrica-
tion points yourself and provide additional lubrica-
tion if necessary. Refer to Lubrication on Page
43 for specific details.
Tensioning &
Tracking Blade
Blade tension directly affects blade tracking so it
is important to adjust them together.
Tensioning Blade
Proper blade tension maximizes the life of the
blade and bandsaw components, improves cut-
ting performance, and reduces the risks related to
blade breakage.
When tensioning the blade, avoid the urge to over-
tension it. Too much tension reduces the life of the
bandsaw bearings and the blade.
Tools Needed
Hex Wrench 5mm, 6mm ........................... 1 Each
Open-End Wrench or Socket 17mm .................. 1
To tension the blade:
1.
DISCONNECT BANDSAW FROM POWER!
2.
Open the upper wheel door.
Model G0806/G0807 (Mfd. Since 12/15)
3.
Use the guide post knob (see Figure 22) to
raise the upper blade guides to the highest
position.

4.
Check the deflection of the blade by pushing
it with moderate pressure midway between
the upper blade guides and the table (see
Figure 23). The proper amount of deflection
is approximately
Figure 23. Proper amount of blade deflection.
Note: The most accurate way to check blade
tension is to use a tensioning gauge. Grizzly
offers the Model H5408 Blade Tensioning
Gauge (refer to Page 41).
5.
Use the blade tension handwheel (see
Figure 22) to make adjustments until the
blade is properly tensioned.
Qty
Note: Turn the handwheel counterclockwise
(as viewed from underneath it) to decrease
tension, and clockwise to increase tension.
