To adjust/replace the knives:

1.DISCONNECT THE JOINTER/PLANER FROM THE POWER SOURCE!

2.Remove the cutterhead guard from the table, and flip up the lower the infeed and outfeed tables. This will give you unrestricted access to the cutterhead.

3.Remove the motor access panel to expose the motor pulley.

4.Rotate the motor pulley to give you good access to one of the cutterhead knives.

Knives are sharp! When adjusting knives, wear gloves or cover knives with rags to avoid contact with knives, which could cause serious personal injury.

5.Loosen the cutterhead gib bolts, starting in the middle and alternating back and forth until all of the gib bolts are loose, but not falling out.

—If this is the first time you are setting the knives, remove the gib and knife from the cutterhead. Decide which adjustment option you are going to use between the jack screws and the springs.

—If you decide to use the jack screws, remove the springs from the cutterhead (they are located directly below the knives).

—If you decide to use the springs, just thread the jack screws completely into the cutterhead so they will not get lost. Replace the gib and knife.

6.Remove and clean the gibs and clean inside the cutterhead slot to remove all pitch or saw- dust. Coat the knives and gibs with a metal protectant (Page 32), then fit the gibs back in the cutterhead with the new knives.

7.Adjusting the knife heights:

-44-

Jack Screws: Using a 3mm hex wrench, find the jack screws through the access holes in the cutterhead (Figure 62) and rotate them to raise/lower the knife. When the knife is set correctly, it will barely touch the middle pad of the knife setting gauge. For now, only tighten the gib bolts enough to hold the knife in place. Repeat Steps 5–7with the other knives.

Figure 62. Jack screw access hole.

Springs: Push the knife down with the gauge so that the knife edge is touching the middle pad of the gauge. Hold the gauge down and only tighten the gib bolts enough to hold the knife in place. Repeat Steps 5–7with the other knives.

8.Rotate the cutterhead to the first knife you started with. Slightly tighten all the gib bolts by following the tightening sequence show in Figure 63. Repeat this step on the rest of the knives, then final tighten each gib bolt.

9.If you used the knife setting gauge to set the knife heights, use the straightedge to adjust the outfeed table height evenly with the knives at top dead center (the highest point in their rotation). If you used the straightedge to set the knife heights, skip to the next step.

10.Replace the cutterhead guard and the motor access panel.

G0633/G0634 specifications

The Grizzly G0633 and G0634 models are two impressive machines in the realm of woodworking and metalworking equipment. Both models have gained a loyal following among woodworkers and metal fabricators for their exceptional performance, reliability, and innovative features.

One of the most prominent characteristics of the Grizzly G0633 is its robust build quality. Constructed from heavy-duty cast iron, this bandsaw promises durability and stability during operation, minimizing vibrations and ensuring clean, precise cuts. The G0634, an evolution of the G0633, offers enhanced features that cater to both hobbyists and professionals in various industries.

Both models boast powerful motors that ensure smooth and efficient operation. The G0633 is equipped with a 1 HP motor, while the G0634 comes with a more robust 1.5 HP option, allowing for deeper cuts and handling denser materials. This increased power translates to faster material removal rates and improved productivity on the shop floor.

The G0633/G0634 features a dual-speed function, allowing users to adjust the blade speed according to the material being processed. This flexibility is crucial for achieving optimal results on different materials, whether it's hardwood, softwood, or non-ferrous metals. Additionally, the blade guides on both models are precision-engineered, ensuring minimal friction and longer blade life.

Another standout feature is the large cutting capacity these machines offer. The G0633 provides a resounding 12 inches of throat depth, while the G0634 expands this to 14 inches. This increased capacity is a significant advantage for users tackling larger projects or working with oversized stock.

For user convenience, both models are designed with easy adjustments in mind. The quick-release blade tensioning system simplifies blade changes, while the height-adjustable table enhances user ergonomics. The tables are also made of high-quality cast iron, providing a stable surface for workpieces.

Incorporating advanced safety features, the G0633 and G0634 prioritize operator protection. Each model is equipped with a blade brake system that halts blade movement almost instantaneously when the safety switch is triggered. This is a critical function for preventing accidents during operation.

Ultimately, the Grizzly G0633 and G0634 stand out in the market for their excellent balance of power, versatility, and safety. With their outstanding cutting capabilities and engineered precision, these bandsaws are excellent choices for any workshop aimed at producing high-quality workpieces. Whether for a professional environment or a dedicated hobby shop, both the G0633 and G0634 continue to meet and exceed the expectations of craftsmen and creators everywhere.
