Maintenance - DeWalt DCG406 Original Instructions Manual

Cleaning and Disposal
1. All surfaces in the work area should be vacuumed and
thoroughly cleaned daily for the duration of the sanding project.
Vacuum filter bags should be changed frequently.
2. Plastic drop cloths should be gathered up and disposed of
along with any dust chips or other removal debris. They should
be placed in sealed refuse receptacles and disposed of through
regular trash pick‑up procedures.
During clean up, children and pregnant women should be kept
away from the immediate work area.
3. All toys, washable furniture and utensils used by children
should be washed thoroughly before being used again.
Edge Grinding and Cutting

WARNING: Do not use edge grinding/cutting wheels for
surface grinding applications because these wheels are not
designed for side pressures encountered with surface grinding.
Wheel breakage and injury may result.

CAUTION: Wheels used for edge grinding and cutting may
break or kick back if they bend or twist while the tool is being used.
In all edge grinding/cutting operations, the open side of the guard
must be positioned away from the operator.
NOTICE: Edge grinding/cutting with a Type 27 wheel must be
limited to shallow cutting and notching—less than 13 mm
in depth when the wheel is new. Reduce the depth of cutting/
notching equal to the reduction of the wheel radius as it wears
down. Refer to the Accessory and guard Applications Chart
for more information. Edge grinding/cutting with a Type A wheel
requires usage of a Type 1 guard.
1. Allow the tool to reach full speed before touching the tool to
the work surface.
2. Apply minimum pressure to the work surface, allowing the
tool to operate at high speed. Grinding/cutting rate is greatest
when the tool operates at high speed.
3. Position yourself so that the open‑underside of the wheel is
facing away from you.
4. Once a cut is begun and a notch is established in the
workpiece, do not change the angle of the cut. Changing
the angle will cause the wheel to bend and may cause wheel
breakage. Edge grinding wheels are not designed to withstand
side pressures caused by bending.
5. Remove the tool from the work surface before turning the
tool off. Allow the tool to stop rotating before laying it down.
Cutting Metal
For cutting with bonded abrasives, always use the
guard Type A.
When cutting, work with moderate feed, adapted to the
material being cut. Do not exert pressure onto the cutting disc,
tilt or oscillate the machine.
Do not reduce the speed of running down cutting discs by
applying sideward pressure.
The machine must always work in an upgrinding motion.
Otherwise, the danger exists of it being pushed uncontrolled
out of the cut.
When cutting profiles and square bar, it is best to start at the
smallest cross section.
Rough Grinding
never use a cutting disc for roughing.
Always use the guard Type B.
The best roughing results are achieved when setting the
machine at an angle of 30° to 40°. Move the machine back and
forth with moderate pressure. In this manner, the workpiece
will not become too hot, does not discolour and no grooves
are formed.
Cutting Stone
The machine shall be used only for dry cutting.
For cutting stone, it is best to use a diamond cutting disc.
Operate the machine only with additional dust protection mask.
Working Advice
Exercise caution when cutting slots in structural walls.
Slots in structural walls are subject to the country‑specific
regulations. These regulations are to be observed under all
circumstances. Before beginning work, consult the responsible
structural engineer, architect or the construction supervisor.

MAINTENANCE

Your D WALT power tool has been designed to operate
e
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regular cleaning.

WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect battery pack before making
any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury.
The charger and battery pack are not serviceable.
Lubrication
Your power tool requires no additional lubrication.
Cleaning

WARNING: Electrical shock and mechanical hazard.
Disconnect the electrical appliance from the power source
before cleaning.

WARNING: To ensure safe and efficient operation, always
keep the electrical appliance and the ventilation slots clean.

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.
Ventilation slots can be cleaned using a dry, soft non‑metallic
brush and/or a suitable vacuum cleaner. Do not use water or
any cleaning solutions. Wear approved eye protection and an
approved dust mask.
Optional Accessories

WARNING: Since accessories, other than those offered by
D WALT, have not been tested with this product, use of such
e
accessories with this tool could be hazardous. To reduce the risk
of injury, only D WALT recommended accessories should be used
e
with this product.

WARNING: Do not use a bonded abrasive wheel that is
past its expiration (EXP) date as marked near center of wheel
(if provided). Expired wheels are more likely to burst and cause
serious injury. Store bonded abrasive wheels in dry location
without temperature or humidity extremes. Destroy expired or
damaged wheels so they cannot be used.
