MAINTENANCE

Your DEWALT power tool has been designed to

operate 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 tool from

power source before making any

adjustments or removing/installing

attachments or accessories. Before

reconnecting the tool, depress and

release the trigger switch to ensure that

the tool is off.

The charger and battery pack are not serviceable.

There are no serviceable parts inside.

Pop-off Brushes

The motor will be automatically shut off indicating

that the carbon brushes are nearly worn out and

that the tool needs servicing. The carbon brushes

are not user-serviceable. Take the tool to an

authorised DEWALT repair agent.

Lubrication

Your power tool requires no additional lubrication.

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.

CHARGER CLEANING INSTRUCTIONS

WARNING: Shock hazard. Disconnect

the charger from the AC outlet before

cleaning. Dirt and grease may be

If the power supply is shut off by the RCD, take the

tool to an authorised DEWALT repair agent.

WARNING: In extreme working

conditions, conductive dust can

accumulate inside the machine housing

when working with metal. This can

result in the protective insulation in the

machine becoming degraded with a

potential risk of an electrical shock.

To avoid build-up of metal swarf inside the machine,

we recommend to clear the ventilation slots on a

daily basis. Refer to Maintenance.

Cutting Metal

For cutting with bonded abrasives, always use

the guard type 1.

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 27.

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.
