Grizzly Essential Adjustments for the G0640X Bandsaw: Blade Speed and V-Belt Management
Page 33

Blade Speed

This bandsaw features a variable blade speed between 100–3600 FPM. There are two blade speed ranges. A fast range for wood cutting and a slow range for metal cutting.

The variable speed dial controls the blade speed within each range. The position of the V-belts behind the lower wheel cover control which speed range is activated. A disc with a spiral shape is located near the motor as a reminder to the oper- ator which blade speed range is engaged. The disc spins when the metal cutting speed range is engaged.

The V-belt tension is controlled in two ways, depending on which position it is in. When in the "wood" position, the V-belt tension is controlled by the position of the motor, which pivots to ten- sion/loosen the belt.

At "metal" position, the V-belt tension is controlled by the hand crank located between the dust ports.

5.Move the V-belt(s) to the desired position.

6.Tension the V-belt(s) to deflect approximately 1⁄2" (see Figure 42).

Note: If one belt is used more than the other belt, it will stretch slightly under normal condi- tions. This means that one belt may be looser than then other when both belts are installed. This is normal. Overtightening one belt in attempt to tighten the other will decrease the lifespan of the bearings in the pulleys.

7.Close all wheel covers.

8.Press the button below the "Blade Speed" digital display to light up either the "Wood" or "Metal" light so it matches your V-belt set- ting.
