MOUNTING WIRE 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.
NOTICE: To reduce the risk of damage to the tool, properly seat the
wheel hub before turning the tool on.
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.
4. Maintain contact between the edge of the wheel and the work
surface with wire wheels.
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.
MAINTENANCE
WARNING: To reduce the risk of injury, turn unit off and
disconnect it from power source before installing and removing
accessories, before adjusting or when making repairs. Before
reconnecting the tool, depress and release the trigger switch
to ensure that the tool is off. An accidental start-up can cause
injury.
Your D WALT power tool has been designed to operate over a
E
long period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and regular
cleaning.
Lubrication
Your power tool requires no additional lubrication.
Motor Brushes
This D WALT tool uses an advanced brush system which auto-
E
matically stops the tool when the brushes wear out. This prevents
seri ous damage to the motor.
Cleaning
WARNING: Blow dirt and dust out of the main housing with dry air
as often as dirt is seen collecting in and around the air vents. Wear
approved eye protection and approved dust mask when performing
this procedure.
WARNING: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. These chemicals may
weaken the materials used in these parts. Use a cloth dampened only
with water and mild soap. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.
