The unpainted surfaces are coated with a waxy oil to prevent corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. For thorough cleaning, some parts must be removed. For optimum performance from your machine, clean all moving parts or sliding contact surfaces.

(see Wheel Alignment on Page 42). When wheels are coplanar, vibration and heat are reduced during operation. The wheels on the Model G0621 are factory aligned, so center tracking is the only adjustment that needs to be performed during setup.

Page 21: Tensioning Blade
After blade tension and tracking are set cor- rectly, properly adjust the upper/lower sup- port bearings and guide-block assemblies into position before operating machine. G0621 Wood/Metal Bandsaw Adjusting Support Bearings The support bearings are positioned behind the blade to support it during cutting operations.

Page 25: Aligning Table
Adjust the table as needed until the distance between the blade and miter slot is equal at both ends. Tighten the trunnion bolts. G0621 Wood/Metal Bandsaw Aligning Fence To ensure cutting accuracy, the fence must be parallel with the miter slot.

Page 29: Ripping
ALWAYS use a push stick when ripping narrow pieces. Failure to fol- low these warnings may result in serious personal injury! G0621 Wood/Metal Bandsaw Crosscutting "Crosscutting" means cutting across the grain of wood. For plywood or metal, crosscutting simply means cutting across the width of the workpiece.
Page 30: Resawing
Turn the bandsaw ON. Using push paddles and a push stick, main- tain workpiece pressure against the fence and table, and slowly feed the workpiece into the moving blade until the blade is completely through the workpiece (see Figure 34). G0621 Wood/Metal Bandsaw...

''... 3 ⁄ ''... 5 Figure 35. Blade width radii. G0621 Wood/Metal Bandsaw One of the benefits of a bandsaw is its ability to cut multiple copies of a particular shape by stack- ing workpieces together and cutting them as one.
Page 32: Blade Selection (Wood Cutting)
Measured by the circumference, blade lengths are usually unique to the brand of your bandsaw and the distance between wheels. The Model G0621 uses 108" long blades. Refer to Page 35 for blade replacements. Blade Width Measured from the back of the blade to the tip of...
Page 33: Tooth Pitch
A clean blade will perform much better than a dirty blade. Dirty or gummed up blades pass through the cutting material with much more resistance than clean blades. This extra resistance also causes unnecessary heat. Grizzly sells resin/pitch dissolving cleaners that are excellent for cleaning dirty blades. Blade Breakage Many conditions may cause a bandsaw blade to break.
