DeWalt D28115R Mounting and Using Cutting Type 1 Wheels, Using Wire CUP Brushes and Wire Wheels

1.Thread the wheel on the spindle by hand.

2.Depress spindle lock button and use a wrench on the hub of the wire wheel or brush to tighten the wheel.

3.To remove the wheel, reverse the above procedure.

CAUTION: Failure to properly seat the wheel hub before turning the tool on may result in damage to tool or wheel.

USING WIRE CUP BRUSHES AND WIRE WHEELS

Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing irregular surfaces.

1.Allow the tool to reach full speed before touching the tool to the work surface.

2.Apply minimum pressure to work surface, allowing the tool to

operate at high speed. Material removal rate is greatest when the tool operates at high speed.

3. Maintain a 5˚ to 10˚ angle between the tool and work surface for wire cup brushes.

Mounting and Using Cutting (Type 1) Wheels

Cutting wheels include diamond wheels and abrasive discs. Abrasive cutting wheels for metal and concrete use are available. Diamond blades for concrete cutting can also be used.

NOTE: All grinders that use Type 1 wheels use the quick-change backing flange (G1).

WARNING: A closed, 2-sided cutting wheel guard is not included with this tool and is required when using cutting wheels. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel contact. See page 8 for more information.

MOUNTING CLOSED (TYPE 1) GUARD

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or acces- sories. Before reconnecting the tool, depress and release the trigger switch to ensure that the tool is off.

5. Continuously move the tool in a forward and backward motion to avoid creating gouges in the work surface. Allowing the tool to rest on the work surface without moving, or moving the tool in a circular motion causes burning and swirling marks on the work surface.

6.Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating before setting it down.

CAUTION: Use extra care when working over an edge, as a sudden sharp movement of grinder may be experienced.

2.	Push the guard down until the
	guard lug engages and rotates
	freely in the groove on the gear
	case hub.
3.	Rotate guard (D) into desired
	working position. The guard body
	should be positioned between the
	spindle and the operator to provide
	maximum operator protection.
4.	Close the guard latch to secure the
	guard on the gear case cover. You
	should be unable to rotate the
