How should the tool be operated?

• It should never be necessary to force the tool. The weight of the tool applies adequate pressure. Forcing and excessive pressure could cause dangerous wheel breakage.
• ALWAYS replace the wheel if the tool is dropped while grinding.
• NEVER bang or hit grinding disc or wheel onto work.
• Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kickback.
• NEVER use the tool with wood cutting blades and other saw blades. Such blades when used on a grinder frequently kick and cause loss of control leading to personal injury.
• Never switch on the tool when it is in contact with the workpiece, it may cause injury to the operator.
• ALWAYS hold the tool firmly with one hand on the housing and the other on the side handle.

---

How do I use the tool?

1. Turn the tool on and then apply the wheel or disc to the workpiece.
2. In general, keep the edge of the wheel or disc at an angle of about 15° to the workpiece surface.
3. During the break-in period with a new wheel, do not work the grinder in a forward direction or it may cut into the workpiece.
4. Once the edge of the wheel has been rounded off by use, the wheel may be worked in both forward and backward directions.

---

What should I ensure when using an abrasive cut-off / diamond wheel?

• Be sure to use only the special wheel guard designed for use with cut-off wheels.
• NEVER use cut-off wheel for side grinding.
• A diamond wheel shall be operated perpendicular to the material being cut.

---

What should I avoid when using an abrasive cut-off / diamond wheel?

• Do not “jam” the wheel or apply excessive pressure.
• Do not attempt to make an excessive depth of cut.
• During cutting operations, never change the angle of the wheel. Placing side pressure on the cut-off wheel (as in grinding) will cause the wheel to crack and break, causing serious personal injury.
• Do not start the cutting operation in the workpiece.

---

How should I start a cutting operation with an abrasive cut-off / diamond wheel?

Let the wheel reach full speed and carefully enter into the cut moving the tool forward over the workpiece surface. The wheel may bind, walk up or kickback if the power tool is started in the workpiece.
